I have two hard disks sda and sdb. I have Windows XP installed on sda2 and Ubuntu 10.04 on sdb5. When I installed Windows XP, Ubuntu stopped booting. I tried to repair grub2 from a Live CD unsuccessfully. Now I have completely messed up my MBR of both HDDs. I just want to configure grub2 to load both OSes in dual boot mode.
View 9 Repliesi 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.

I recently got a netbook and setup as dual boot between win7 starter and 9.10 (64bit). Win 7 starter is not impressive so i want to nuke it and give the space all to my /USR partion. I am comfortable working with Gparted and assume that i can launch using my gparted live usb and delete the windows partion and then resize the /usr partion.
what changes do i need to make w/ Grub2? I would prefer not to see the Grub menu at all and have it load right the main kernel if possible. Also, if this is possible is there a way to get to the Grub menu during boot should i need to select a different kernel?
After installing karmic with Grub2 I am unable to boot into Archlinux partition. Grub2 has removed the last line of the Archlinux boot stanza! It used to read:-

But no luck. Only way into Archlinux is to get into the edit shell and manually add the missing line and remove other stuff not needed. I have spent hours trying to resolve this issue and I am fairly p----d off
I've already had WinXP SP3 installed on one HDD, so i've installed 10.04 on my spare HDD. When I try to boot to Win, I get ntoskrnl.exe missing error. This is my boot info script report:

I recently installed Ubuntu 10.04 on my dual boot system and noticed that my boot options were changed. I typically have Windows XP as the default OS. Here are the steps that worked for me to get Windows XP as the default boot using Grub2.During my initial Window XP install I had partitioned my hard drive into 3 partitions:
Code:
Partition 1: NTFS format (Windows XP installation) in Linux it is called /dev/sda1
Partition 2: NTFS format (Data for Windows XP) in Linux is is called /dev/sda5
[code]....
Been using Linux for many many years but Grub2 is annoying the heck out of me at the moment.
My home desktop PC is set up as follows:
/dev/sda � 40GB 10k Raptor with Ubuntu 10.10 installed
/dev/sdb � 500GB HDD formatted to ext4
/dev/sdc � 500GB HDD split up as follows:
/dev/sdc1 � 80gb NTFS partition with Win7 installed
/dev/sdc1 � Remaining drive space NTFS but nothing on it yet
Grub2 refuses to detect that Windows is installed on the 3rd HDD. I've googled and spent hours trying all sorts of things to get it to detect it and add it to my boot menu.
If I disconnect all drives except the Windows drive it boots up straight into Win7, so it's healthy and happy. (as healthy and happy as Windows can be, I need it for work purposes only!)
Does anyone have any tips on what would be the best method to force grub to realise that Windows is sitting there?
As far as I understand, the Win7 partition should be (hd2,1) � does that sound right to you?
I haven't tried booting off an Ubuntu CD and re-installing grub, since I can get into Linux and all the guides seem to be about how to restore grub after a Windows install eats it...
I'm thinking of dual-booting Ubuntu 10.10 and Arch Linux. It seems that I'll have to do some editing of the grub.cfg file, but I have seen numerous warnings not to do so. After a bit of poking around, I've heard about a script that does the editing for you built in to Linux (or maybe just Ubuntu).
My questions are:
- If the aforementioned script does exist, how do I use it?
- else if it doesn't exist, how do I not directly edit grub.cfg?
Problems with dual boot, grub2 auto os prober
Drive #1 (sda) Master CS Ubuntu 9.04 grub upgraded to grub2 version 1.96
Drive #2 (sdb) Slave CS Ubuntu 9.10 grub2 version 1.97 /boot is (sdb1) root is (sdb5)
grub2 is installed in /boot (sdb1) and the mbr of (sdb)
I want to be able to boot drive #2 from drive #1 grub menu at boot time. I have run �update-grub and it probes and finds (sdb5) and creates a new grub.cfg called grub.cfg.new in the /boot folder, but the new cfg file does not show (sdb5) or (sdb) it shows all other changes that I made such as splash screens and they are working. How do I get it to recognize drive #2 with Ubuntu 9.10. I can boot each drive independently of one another and I can boot 9.04 with 9.10 if I swap the drives around. And run update-grub The auto probe is working in the Ubuntu 9.10 and may be working partly in the 9.04.
This may or may not be a problem, but is a pain anyway. When I run update-grub in 9.04's grub version 1.96, it does not change anything in the current grub.cfg it does make a new file called grub.cfg.new I have to go into /boot/grub and change grub.cfg to old and change grub.cfg.new to grub.cfg I do not have this problem running the same command in Ubuntu 9.10's grub. It finds changes and os's and automatically updates the current grub.cfg
is it possible to edit Grub2 to hide the rectangular frame around the selectable OSes? Also, is it possible to hide the Grub 'title' ("Grub GNU 2 (1.97~beta4)" et cetera)?
View 1 Replies View RelatedI've just installed the 64 bit edition of 9.10 on my workstation. My raid drivers worked without any custom installation, which is very impressive! I am however having a problem installing grub2. I boot to the live CD, run the install process, resize and partition my free space as an ext4 primary partition with mount point /. Everything installs except grub, so I'm always booting in to windows.This seems to be a bit off as I've never had this occur with dual booting before.
View 9 Replies View RelatedI have a Dell Studio 14 laptop with Windows 7 64bit preinstalled. The processor is core i5 and the machine has 4GB RAM. I freed 25GB of memory from my Hard disk and tried to install Ubuntu 10.04 (AMD). Everything went fine. I restarted and Logged into Ubuntu. It worked like a charm. Then I restarted to Windows7. This also worked well as expected.
But, when I rebooted again, I got a black screen saying that �No modules found. Press any key to restart�
When I press a key, it says �No operating system found�, probably after checking through a network (it printed lines starting with PXE).
I tried exactly in the same way with Ubuntu 8.04 in my machine, and this worked without any problem. The Bootloader was not corrupted after restarting from Windows. I noticed the problem with Ubuntu 9.10 and 10.04. I feel like a problem regarding the bootloader version. AFAIK, 9.10 and 10.04 is using GRUB2 when 8.04 use the old version of GRUB. Will I have to switch to the legacy GRUB? (I would love to keep using GRUB2). If yes, I would like to know How.
I have a Dell ZINO HD and dual booted fine prior to 10.04. Grubs seems to not identify the Win7 OS partition correctly. According to Disk utility DEV/SDA1 is a DELL utility partition, DEV/SDA2 is the RECOVERY partition, DEV/SDA3 is my Win7 OS partition...and DEV/SDA5 is my Linux partition. Ubuntu boots fine... but with GRUB using SDA2 (HD0,2) for win7 I cannot boot to it... is there a fix?
The following is in my GRUB.CFG file

I want to load grub2 from grub4dos.I want to load directly the grub2 core. I know how to load first 512 bytes from some patition by chainloader and load grub2, but what I need is to load directly grub2 core without passing by bootstriping code (first 512 bytes).So, my first boot manager is grub4dos, then I can load grub2 and later I load Ubuntu. But I think I have to edit --set-root
What I dont know is how.
In hdd 0,7 (sda8) I have Ubuntu 10.10 and /boot/grub/core.img is in sda8 (hd0.7)
I tried this way:
Code:

kernel /boot/grub/core.img
The system came with Windows 7 installed.
After installing Ubuntu 11.04 (Natty) with Unity, I installed Xubuntu 11.04. All three OSes could be seen in the GRUB menu and I could boot any OS of choice.
Then I installed OpenSUSE 11.4. I suspect it installed legacy GRUB on the OpenSUSE root partition. Thereafter, I was not able to boot Ubuntu or Xubuntu.
I have now used a LiveCD (system rescue mode) to re-install GRUB on the MBR. However, I can only boot Win7 or Ubuntu. Can't access Xubuntu or OpenSUSE.

I managed somehow to successfully install a dual boot with Ubuntu 9.02 and Windows XP. Ubuntu was on a PATA drive and the WinXP was on a SATA drive. The SATA drive was configured to boot first. As I was having problems with Ubuntu I booted into WinXP, re-formatted the PATA drive, then restarted the computer and installed Ubuntu 9.10. It all went well.I rebooted the machine and the following message was on the screen:
GRUB Loading stage1.5.GRUB Loading, please wait....Error 17
I rebooted, changed the boot order so that the PATA disk (Ubuntu) started first, then the SATA(WinXP). Ubuntu loaded up the dual boot screen.I chose WINXP, but I was greeted with a black screen.I rebooted again and chose to load Ubuntu, which it did without a hitch.what I should do to restore my access to WinXP? Or should I start again? If so, how?

I'm having installation issues with linux. I'm trying to set up a dual boot with vista and linux. I prepared my computer by backing up my files and partitioning my hard drive, leaving 20GB for linux. I downloaded Linux Mint 7, and booted from USB (using the universal USB installer from pendrivelinux.com). All good, entered into linux and installed by following the prompts (selecting use largest unallocated partition to point linux to the partition). At this stage the screen cleared to just leave me with the desktop background.
I patiently waited for it to reboot which never happened. So I waited for 20mins or so, then shut the computer down because I couldn't think of what else to do. When I restarted (without using the livecd/usb) it just went straight to vista. I did a bit of reading and found it might have been something to do with vista taking over grub, and some of the tutorials suggested downloading EasyBCD. So I did that, here's the summary:

-my hdd is 320 so i separated 200(for win 7) , 50 (for personal ) , 40 unallocated for linux
-inserted ubuntu 10.04 rc1 CD
- in fourth step when selecting disk , i selected manual option(3rd)
- and i selected 40GB unallocated and formatted to ext4 and selected as root and install

I've set up a triple boot system (Ubuntu Karmic, Windows Vista and OSX86 -- a patched OS X which works on a PC) on a Dell 9200 (C2D 2.13 GHz, 4GB RAM, nVidia G210). I sue Grub2 as the bootloader and update-grub picks up OS X and it boots without any problem.
However, although when booting OS X using its own Darwin bootloader, I can apply the boot option "Graphics Mode"="1680x1050x32" to ensure that I get the screen resolution that I want, when OS X boots from Grub2, the only resolution available is 1024x768 which is disappointing. I have tried adding gfxmode=1650x1050x32 to the OS X section of /boot/grub/grub.cfg in Ubuntu but this does nothing.
I am unable to load Ubuntu onto computer as dual boot or inside windows. Thus scanned the CD and found it has 23 errors.Are these files suppose to be on the CD?casper, .disk, install, install, isolinux, pics, pool, pressed, autorun, md5sum.

I have a number of legacy pcs upon which I would like to install Lubuntu. None have CDROM drives, but they do have floppy drives. None can natively boot from USB devices. My goal is to boot into Grub2 from a floppy with USB support, but I'm having trouble making the floppy. I've seen recommended a few times a command string something like
Code:
grub-mkrescue --overlay=/boot/grub --image-type=floppy GRUB2.img
dd if=GRUB2.img of=/dev/fd0
But when I go to do this, grub-mkrescue has no --overlay nor --image-type option. My man grub-mkrescue page only lists --modules and --output as options. I have managed to make a floppy using the commands
Code:
grub-mkrescue --output=FILE
dd if=FILE of=/dev/fd0
This disk does boot into Grub2. The problem with this is that I need to add other files to the disk to have USB functionality in Grub2, but this process writes to the floppy in iso9660 format, which mounts as read-only. I have tried to go this route using the mount -o remount option to try to make the fs rewritable, but I also haven't been successful with that (and I think my limited knowledge is restricting me here).
Maybe I can add the correct files to the file output by grub-mkrescue --output before I write it to the floppy, but I also don't know how to do that.
Basically, I'm a little burned out and looking for some direction. Am I going about this wrong? When I try and follow other people's guides, they seem to have options available to them that I don't have. I'm doing all this from my Lubuntu 10.04 live CD, but have found similar things on my regular Ubuntu 10.04 install as well.
