Debian Configuration :: Grub2 Multi Boot With XP ?
Jun 29, 2011
I recently upgrade my grub to grub2 and had problem to boot debian. After trying to fix it myself, I played around with grub-image-ntldr, my debian now works ok, but I cant boot my XP anymore.
Now when I try to boot XP, I got "No grldr" message. If I copy my ntldr and rename it to grldr, my XP will boot ok. So it seems that when I try to boot XP it doesn't chainload ntldr anymore, it is looking for grldr.
I tried to change "chainload +1" to "chainload /ntldr", it complains about invalid signature. Does anyone knows why my grub now using grldr instead of ntldr?
there were no entries in the Grub 2 menu after booting. I don't really understand the numbering of hd0,0 to like sda, but I changed "root (hd1,0)" to "root (hd0,0)" if Windows is on hd0, but after rebooting, I still didn't see it. I read somewhere that Grub2 starts partitions at 1, but wasn't sure that was true because in menu.lst they start with 0 sometimes. know entry-level steps to solve this?
I upgraded a while back to Windows 7. I run two separate HDDs, with debian on sda and windows on sdb. Everything worked fine, up until i upgraded to windows 7. The installer forced me to unplug sda. After installing I repositioned the HDDs and was stuck with a "NTLDR is Missing" message. After removing the search -fs--uuid tag from grub.cfg, Windows 7 booted for a good 0.5 sec and then rebooted. All that flashed was the "Starting Windows" page. I see similar bugs reported in the launchpad, but nothing that directly parallels this.
Here's my windows entry in grub.cfg:
Changing ${root} to (hd1) makes no difference. Also, I've been using Windows 7 for moths now without a problem, it's only when I try and boot it form grub2 that I get a problem. Physically removing sda lets Windows 7 boot fine.
i created a second instance of postfix.It isn' t the first time that i made this procedure but with debian i had a lot of problem.I think that the problem is chroot configuration of postfix .In the first i had two problem smtp “fatal: unknown service: smtp/tcp” and the second instance was enable to make nslookup of domain.I copied the necessary file in /var/spool/postfix-second-instace and i solved the errors.Now the problem is that there aren't error in log file but connect to xxx.xxx.net[yyy.nn.yyy.yyy]:25: Connection timed out for all connection. and the email are all in defer directory and the second instance doesn' t send emails.
I have Lenny, and Jaunty Jackaope installed on the same hdd. Jaunty Jackaope was installed 2nd so it has control of grub (I don't know if that is the correct expression) I want to remove Jaunty Jackalope however I know from past experience that after I do this I will no longer be able to boot into Lenny as I will get a grub error at startup. How to I give boot/grub to Lenny so that I can remove the other operating system?
After removing a hard drive I (thought I)wasn't using, GRUB failed to load(turns out stage1 was on that drive) and it refused to install to a new drive(even after I kexec'd into the system - which was fun, considering the LiveCD used a different name for the hard drive). I finally threw in the towel and installed GRUB2, which worked after removing a second, incorrect root=. However, I can't find out how to switch the font from the fugly default to something that doesn't try to gauge my eyes out with a rusty spoon.
I have just upgraded from Lenny to Squeeze, and followed the D-I recommendation to upgrade to Grub2. However, the server will no longer boot - giving a 'missing operating system' error, so it's not getting very far in the boot loader process. I have read, in various location that Grub2 supports GPT, but my efforts to fix the situation have met with little success.
I have managed to boot the system using SuperGrub2 (recovery live cd) and can start up successfully from there. However, when I try to fix the grub installation using the Debian wiki recommendation, I'm met with:
<host>:/# grub-install /dev/sda /usr/sbin/grub-setup: warn: This GPT partition label has no BIOS Boot Partition; embedding won't be possible!.

The attached disk is 4.5TB of RAID 5 disk behind an Adaptec 5405 if that's useful.
Daily updated Debian Testing Because Debian is the only operating system on this laptop and I keep at least two working kernels, I would like to hide Grub2's menu unless I press a key (like one could do with Grub). I can hide the menu if the line GRUB_TIMEOUT=0 is in /etc/default/grub but it doesn't appear after pressing SHIFT, which is a threat if the system cannot boot the selected kernel. Right now, the timeout is set to one second. I've read Grub2's documentation and [URL] and tried various combinations, but I haven't been able to make this work.
I just got a new hard drive and figured I might as well do an installation of Squeeze (and was previously using Lenny). That went fine, and then I decided that I should copy over my old Lenny installation to the new disk -- mostly to have a working backup without bothering to do a new installation on a partition of the new drive. My partition scheme was a smaller /boot partition and then a much larger / partition with everything else standard (and a much larger /data partition rather than storing everything under /home). So I copied /boot over to a new partition on the new disk, and the same with /. That was done from the Squeeze installation, so the Lenny install wasn't active at the time. I modified all the appropriate entries in /etc/fstab to use UUIDs rather than partition numbers and ran an update-grub.
It detected everything on the old and new disks without a problem. When I went to try and boot up the transferred Lenny installation, it hung on trying to activate the root file system (I've forgotten the exact messaging). Not entirely unexpected, mind you. I went and took a look at the grub.cfg file. It does list that the transferred Lenny is on partition sda8 (correct), it has the correct uuid for the boot partition... but it seems to be setting the root incorrectly. Specifically, the root is still set for the old disk (though in its new position of hd1 instead of hd0), and the "linux" line sets a root for the old device. Or more specifically, this is the menu entry I get, with a few // comments.
menuentry "Debian GNU/Linux, kernel 2.6.26-2-amd64 (on /dev/sda8)" { insmod part_msdos insmod ext2 set root='(hd1,msdos2)' // <------ This position is the *current* location of my old Lenny disk/partition search --no-floppy --fs-uuid --set [the correct /boot UUID] linux /vmlinuz-2.6.26-2-amd64 root=/dev/sda5 ro vga=795 // <----- that root=/dev/sda5 line is what it was on the old device. initrd /initrd.img-2.6.26-2-amd64 }
The odd thing there is that it sets the root according to the *current* position of the old install disk (maybe some trickery with detecting the correct UUID before setting the root), but the "linux" line refers to the *old* partition. The two lines will never match up no matter what. Now if I edit grub.cfg manually, I can make it boot (and run) normally, as I've verified. For example, I made a couple manual changes to do this:
menuentry "Debian GNU/Linux, kernel 2.6.26-2-amd64 (on /dev/sda8)" { insmod part_msdos insmod ext2 set root='(hd0,msdos3)' // <----------- First hard drive, partition sda3 is where I put /boot search --no-floppy --fs-uuid --set [the correct /boot UUID] linux /vmlinuz-2.6.26-2-amd64 root=UUID=[the correct / UUID] ro vga=795 // <--- Changed it to the UUID here; could be /dev/sda8 instead initrd /initrd.img-2.6.26-2-amd64 }
And that works perfectly, the installation works just fine. Of course, the problem is that those changes will/would be lost every time I run an update-grub. So my question, in a nutshell, is how can I configure things so that update-grub sets things properly to the new devices? Or in other words, where in the copied installation are the variables I need to change? I did note one thing odd -- the existence of a vga=795 line. For the new Squeeze installation, I'm using gfxpayload and there's no vga=anything line anywhere. My old installation, of course, had its own grub installation where I did use vga=795 to set the console resolution properly.
So my first guess was that update-grub (for Grub2) was pulling config information out of the Lenny /boot/grub folder (grub legacy). Unfortunately I tried several changes there and it made no difference. Then I deleted the entire /boot/grub folder entirely from the copied Lenny installation and ran update-grub again (the Squeeze grub version). It changed absolutely nothing. That's very confusing for me, since I have no clue where it could be getting vga=795 from, *except* the now-deleted Lenny /boot/grub folder. Where in the copied Lenny installation, I can change something to make it so that update-grub picks up the correct information?
I just netinstalled Squeeze to a netbook with Windows7. The installation went well without any problem. Linux is also working OK. When I boot now, grub does not show Windows7. I took default settings during installation. I mean I did not do anything special. What should i do to fix it? Should I run osprober and grub-update?
After an update on squeeze about a week or two ago, my console font turned green. I'm not exactly sure of the timing, because I switch between lenny and squeeze, and some time passed between the update and the reboot in squeeze.
During the update, I was asked if I wanted to keep my altered /etc/grub.d/00_header or take the package maintainer's version. I took the PM's version, knowing I'd lose my edit (set gfxpayload=1024x768x16). When I add that line to the new 00_header, run update-grub and reboot, the console font is the size I want, but it's a dull green. Reminds me of my first computer. How do I get it back to white and keep the 1024x768 resolution?
Currently booting with grub-legacy and chainloading grub2. If I boot entirely with grub-legacy, and pass vga=791, the console font will be white. It doesn't matter which kernel I use. Currently, I'm running 2.6.32-3-686. Same behavior exists if I use 2.6.30-2-686. If I use 1024x768x8 I get a dull gray instead of dull green.
Anyone successfully using VNC client on a Mac to control a Debian server?I have the vncserver setup on the Debian machine properly. But I'm having problems connecting to it from both a PowerMac running Tiger and a MacBookPro running leopard.I can connect no problem from a machine running Slack12.2, have not setup port forwarding on my router to connect remotely yet.My Debian machine is running the latest stable release of squeeze with KDE4.I originally tried this with RealVNC Enterprise for OSX but I'm not gonna buy it so I need another alternative after the 30 day trial ends as they have no free version for OSX. The situation is that I do freelance graphic design on the PowerMac with Cinema4D and Photoshop so I spend most of my time on that machine which is located in my home studio in my attic. Aside from the MacBook and a Dell desktop(family machine)all my other machines and network hardware are in the basement. So to go from the attic to the basement everytime I need to do something on another machine is not practical, and the only other machine I need to access on a regular basis is the Debian box in the basement, this makes the most sense.
I also have a 14 year old living in the house and he's fascinated by all this and will meddle in anything he gets the chance to so all the Linux machines and network hardware need to be behind lock and key.
I have a dual boot computer. I seem to be having a bit of a problem with Grub lately. Every time I do any kind of update in Debian Lenny AMD 64 it borks my Grub. The first time I had to change a few lines in menu.lst (hd1,1 to hd0,1), no problem. The second time, things went downhill fast and G-Parted was giving me errors on my NTFS partitions. I had to do an XP repair, fixboot, and I had to reinstall Grub completely to the MBR.
Now, I having a "Grub Loading stage1.5. Grub loading, please wait.... Error 22". All I did was update Debian Linux and shut down. From my initial searches this is an error relating to not finding the correct partition. I have booted with a G-Part CD and it shows all my partitions. I do have a Windows XP Home boot cd if I need it. Here is my partition outline if you need it:
/dev/sda1 NTFS (Windows) flags--boot /dev/sda2 Ext3 (Linux) /dev/sda3 FAT32 (shared space between Windows and Linux) /dev/sda4 extended /dev/sda5 linux-swap
I wrote a GRUB multi-boot configuration so I can boot multiple distributions and have storage space on one 32GB flash drive.
set imgdevpath="/dev/disk/by-label/multiboot"
Code: Select allmenuentry 'Debian Jessie amd64' { set isofile='/iso/debian-8.0.0-amd64-DVD-1.iso' loopback loop $isofile linux (loop)/install.amd/vmlinuz initrd (loop)/install.amd/initrd.gz }
This works in virt-manager when I boot the physical usb device a virtual disk with a usb bus and it works flawlessly, but when I plug it into a physical machine the cdrom detects fails to mount /dev/sdb1 as fstype=iso9660.
i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again. i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.
sudo fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x3c3a81f5
I went through so many post but I haven't found the proper answer yet hope you have an Idea1. Grub2 saves only Linux OS as last selected no Windows OS2.It is possible to boot into a cdrom (drive)?
Whenever I reboot, I get GRUB and the _ pinking, and that's it. With rescue cd I can have chroot shell, to troubleshoot I did the upgrade-from-grub-legacy and installed it to both /dev/sda and /dev/sdb In recovery I redid the upgrade-grub and grub-install commands but still have the same "GRUB and _ blinking".
Because the text "GRUB" and then nothing I didn't enouncter while googling, I need to ask here for further troubleshooting.
I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
A week ago I opened this thread viewtopic.php?f=17&t=61580 in "Board index ‹ Help ‹ Installation" and asked for a moderator to move this to here. Because it hasnt happened up to know, I am reopening the thread here. It would be reeeeally great if somebody could help me with my problem!
I own two computers, one netbook and one laptop. I want to boot my netbook as a diskless client via PXE.I set up a dhcp-, tftp and nfs-server on my laptop but when i boot my netbook, the follwoing messages are displayed:(to make it more clear, i uploaded the whole output and shortened the output below)
I have been frustrated attempting to get Grub2 to boot a Debian Live system from hard disk. Have set aside a 4gb partition /dev/sda1 to contain the Debian Live and some other recovery tools. I actually have them all working from a 4gb USB stick successfully, but getting it to work on my HDD has proved challenging. On USB, I have PartedMagic, Gparted, Grml, and of course my standard 6.01 Squeeze. I have also managed to get the Debian Live booting from that USB stick. Very slick.
However, I can NOT get Debian Live to boot from my HDD; altho all of the others above boot fine. Have tried it two ways - one using an iSO image, which is how it is done on my USB stick. The other attempt is to copy the entire contents of the ISO to a directory.
Here are my directory structures:
debian_live_gnome_squeeze_i386- contains the following: debian-live-6.0.1-i386-gnome-desktop.iso initrd.gz initrd.img vmlinuz which is how it is laid out on my USB stick debian_live - contains the files from the ISO image The error I get is something like "panic unable to find live filesystem" My grub.cfg snippet for the two methods I have tried - the 2nd menuentry is similar to how it works on the USB stick.
menuentry "Debian 6.01 Live (on /dev/sda1)" { insmod part_msdos insmod ext2 set root=(hd0,msdos1)
[code]....
Probly don't really need to get it working since PartedMagic can do almost everything I need for recovery and I can use the USB for reinstall or whatever else.
I have a Dell PowerEdge SC1425 with two SCSI-disks, that I have tried installing Debian Squeeze on. This machine has previously been running Lenny (with grub 1), and the upgrade was done by booting a live-cd, mounting the root partition and moving everything in / to /oldroot/, then booting the netinstall (from USB), selecting expert install and setting up everything (not formatting the partition).
Both disks have identical partition tables: /dev/sda1 7 56196de Dell Utility /dev/sda2 8 250 1951897+ fd Linux raid autodetect /dev/sda3 * 251 9726 76115970fd Linux raid autodetect /dev/sda1 and /dev/sdb1 contain a Dell Utility, that I have left in place. /dev/sda2 and /dev/sdb2 are members of a Raid-1 for swap. /dev/sda3 and /dev/sdb3 are members of a Raid-1 for / formatted with reiserfs.
After installation, grub loads, but fails with the following message: GRUB loading. Welcome to GRUB! error: no such disk. Entering rescue mode... grub rescue>
I can do the following to get grub to boot: set root=(hd0,3) set prefix=(hd0,3)/boot/grub insmod normal normal This will bring me to the grub menu, and the system boots.
It appears that grub has only found md0, which I believe is the swap partition, because ls (md0)/ returns error: unknown filesystem. I have installed grub to both sda, sdb and md1, and tried dpkg-reconfigure grub-pc and dpkg-reconfigure mdadm, as well as update-grub.
I manually added (md1) /dev/md1 to /boot/grub/device.map, but still no result.
I have run the boot_info_script.sh, but unfortunately I cannot attach the RESULTS.txt, because the forum aparently does not allow the txt-extension. Instead I have placed it here: [URL]. I am tempted to go back to grub-legacy, but it seems I am quite close to getting the system working with grub2.
I have just installed Ubuntu (/dev/sda7) and Debian (/dev/sda4), but since I have updated all informations on Ubuntu, then Debian did not appear anymore on the grub list. There is an wiki I have found, but I an not really sure about what to do.
Here are the boot informations: Boot Info Script 0.55 dated February 15th, 2010
Boot Info Summary:
=> Grub 2 is installed in the MBR of /dev/sda and looks at sector 488861020 of the same hard drive for core.img, core.img is at this location on /dev/sda and looks on partition #3 for (,gpt3)/grub.
[Code]...
ps: on this file, it says that the /boot is installed on the MBR and /dev/sda3. I will remove the boot from MBR as I am now using /dev/sda3 instead. Sorry for my english
I have 2 GPUs in my system, a HD4870 and a HD4350. The HD4870 has a Benq 24" and a Dell 17" which are working fine in a multi-display desktop setting (No Xinerama) configured via CCC. On the HD4350 I have a single Samsung 17" which in CCC is listed as '[Unknown Display] Unknown adapter' and cannot be used. How can I get that working properly so I can configure it as an additional screen in this setup?
I have tried a few different configurations in Xorg but I don't have a great understanding of the configuration files so I have broken it a few times. I have read through this guide [URL]. It's a guide based on the work around for multiple Nvidia GPUs with a six monitor configuration while still being able to run visual effects without a hitch. But I didn't continue after reading "If you're prepared to use ATI cards, and therefore deal with their drivers, a better option might be to buy an Eyefinity card." Since that is based on the drivers back then I figure maybe it's possible with ATI drivers now. I'm sticking to Ubuntu this time around there is no doubt there so I would really like to get my third monitor working.
Without going into a lot of the reasons, I have a bootable program on a USB stick that i would like to 'boot' when debian is starting up (or after it completes, or whenever it makes sense to do it). My MB does not support a USB boot, I've removed the floppy and CD so I can add additional HDs (its a small box but well ventilated).
Another option I have is to use my bios 'network boot' option, but I have no clue how to use it and the only description in the mb manual says "Allows system to be booted over a network" In network boots, *usually* one is given an option of specifying a device address, and the network boot executes a boot protocol (e.g. bootp), and the boot image file is downloaded to the target, stored and run out of RAM. No evidence of this behavior is exhibited when the network boot option is selected in the bios...
I have a network with two WAN links. One link is supposed to be for Senior Management and the other for the rest of the company. Currently all traffic seems to be going via one WAN link.
Is it possible to setup squid to select the link to use by checking the mac address of the requesting computer
I know that boot partition is possible to create within debian distribution that has grub 2.0, as I have done before with ubuntu. I have been trying many different options with my preseed file but it keeps taking the boot partition out of LVM and creating and extended partition too and then creates the LVM primary partition.
### Partitioning. # you can specify a disk to partition. The device name can be given in either # devfs or traditional non-devfs format. For example, to use the first disk
Problem: I have installed two Ubuntu servers, 10.04 32-bit and 10.10 64-bit, in a multi-boot environment (also have FDOS and WinXPsp3). The 64-bit will not boot because grub can't find the UUID for the disk with the 64-bit system.
Brief Background: Installed 10.04 LTS two months ago with no problems. 10.04 is in a primary partition on hda with FDOS.
Installed 10.10 (64-bit) in a new primary partition on the same hd. The install seemed to go ok, but the MBR and the fs on the 10.04 were corrupted; could not boot. Restored drive, and rebuilt grub.
Installed 10.10 on separate hd (hdb). In grub step all OS's were recognized so I pointed the grub to hda. Grub failed to boot.
Rebuilt grub from 10.04 on hda. All systems recognized but 10.10 will not boot because it says it cannot locate the UUID specified.
Compared the grub.cfg for both systems, the UUID specified for hdb is the same. Also, when I mount the drive for 10.10 on the 10.04 system the drive UUID is consistent.
I know I must be missing some thing, but I know not what. Have searched and can't find any clues. All other OS's boot ok.
Hardware: AMD64 4GB, 2 internal IDE drives (hda and hdb), 1 internal SATA (hdc WinXP), various USB and Firewire Drives (no bootable systems).
I have successfully configured my system for a multi-seat setup using 2 nvidia cards in Linux Mint 10 and it works great except for a few things that I can't seem to get to work.
1: I can't access any other drives other than the file system drive. All usb flash drives and even esata external hard drives. When I try to mount, it gives me an error: Unable to Mount <drive>, Not Authorized.
2: If not logged into for a while, the second seat (the one on my tv) seems to "go away". I just get no signal on my tv. I have a hunch that this might be the power saver options turning off the display. I think it does it after an hour or so. [EDIT]: just tried to move the mouse and click the keyboard on the no signal screen, it worked!
