Ubuntu Installation :: Grub2 On Re-imaged Machines?
Aug 29, 2010
I just inherited a lab full of computers currently running XP and 9.10. They all worked when I last saw them. Recently, tech support re-imaged the XP partition and now I can't boot into Ubuntu. Obviously it overwrote the bootloader that was there, but I can't get it back. The general setup is XP on /dev/sda1 and Ubuntu on /dev/sdb1 with swap on /dev/sdb5.
I've followed a bunch of instructions about reinstalling grub by chrooting into /dev/sdb1 (right? that's the one I should use), grub-install and update-grub all run without a hitch detect both Ubuntu kernels, memtest and the XP install as they were before the reimage. Exit and reboot, it still boots straight to Windows. If I move the boot flag from sda1 to sdb1, the computer hisses at me about not finding anything to boot.
I've gone nuclear on one computer and installed 10.04 on sdb1, but it still boots to Windows. I feel like I need to do something to the MBR on the Windows drive but last time I did anything there I had to fix it with ms-sys. I left out anything wicked important, I'll get what info you need. Oh and if upgrading to 10.04 in a trick fashion will help me, by all means suggest it, because once they get going I'm upgrading anyway.

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 have an XP laptop which I booted up using an Ubuntu live CD.When I'm in Ubuntu, is there a way that I can access files on the internal laptop XP drive which has been imaged as NTFS? I thought there might be an option through places=>computer, but couldn't see a way.

The problem is every forum I read pretty much ends up with someone suggesting DD, everyone agreeing and the threads dead-end. This is not a good solution for real world large scale usage which is what I'm trying to do. At least it doesn't appear to be unless there is some switch I have misinterpreted when invoking the command. The problem I have with it is it's super bloated and god awful slow. It tries to write out the entire partition or set of partitions (based on the choice I have made) reguardless of if any of the space had been empty, and lets say the partition I copied from was 80 GB and I copy it to a 160 GB disk/partition... I am left with an 80 GB partition and 80 GB unused space and a need to use another tool such as Gparted to resize the newly imaged disk accordingly.
Right now what I use is Norton Ghost and it can do the job I need in only a couple minutes instead of a couple hours and it sizes the partition to max size all at once. I do not want to use this program tho... The fact is in order to make ghost run at a usable speed I have to use it's Windows and not its DOS version which leaves me using something like BartPE and... that's worse than using Windows ME. Surely someone out there has noticed this is a problem and developed a better program that can at least run on par with Ghost.
why I was hoping for a Linux solution it's because I would like to use a "one stop shop" disk, so to speak, where I can boot into a small linux distro such as Puppy and have a full suite at my disposal rather than booting with one disk, wiping, rebooting with another disk, ghosting then testing everything. I suppose if anyone knows of a distro that can already do all that including a good ghost alternative already packaged I would love that.

We are giving away 20+ machines to 3rd world county and I was asked from the receiving party to install linux on them. What I don't want is to pop a cd into all of them and do the manually install.
I'm thinking of installing one computer the old fashion way and do the OEM-configuration on it afterwards. It would be nice to just clone the hard drives since the computer is identical right down to the hard drive.

I do some volunteer work repairing and re-purposing older computers for the Salvation Army Thrift store where I live. Of course most of the computers we get are older. My reason is to get some of the poorer kids a fighting chance at school. We sell these things for next to nothing to accomplish this. I include free tech/training support for 30 days to get them started as. My problem is that finding a version of ubuntu and openoffice that will run on them is becoming difficult. Any suggestions as to a version that works for those not real familiar with computers?

if I need to install Linux o/s in 50 or 100 machines, how do I do it ? (lets imagine that all the machines are identical)
Is it possible to install in one of the machines and just clone in all of the other machines (without actual installation). If so , how do i do it ??

I have VMware player on my laptop. I have three working virtual machines, Android, Windows Vista, and Kubuntu, and three that something went wrong don't work. How do I get rid of these space cloggers? Just go to Home folder/VMware and jus delete the folders of useless machines? Or is there a way to do it properly? Or am I stuck with these forever? And how do I rename a virtual machine?

I have tried to boot from Fedora 10 CD on Compaq Evo D510 desktop as well as HP Pavilion DV6700 Laptop several times. Goes through everything for a long time. Ends up in a screen with colored stripes on the desktop and a blank dark screen on the laptop. I do see the wireless light on the laptop turn blue from orange indicating it is enabled. But was of no use. Both machines crash at the end. I tried both GNOME and KDE.....both crashI am suspecting the display drivers. The desktop has a Intel Chipset and the laptop Nvidia GForce 8600 I guess....These are not old comps. The desktop is just a couple of years old and the laptop is brand new. This is without actually installing Fedora

I have now got three machines with Debian on in my home. I use Mobile Broadband with a very modest monthly limit and remember somehow using Synaptic to gather either Updates or packages to download on one machine where there was another type of internet and could then move the packages back to my computer. Can anyone here remind me of what I would have done there or suggest a means of getting these three updated without blowing my limit. I'd either use a relative's broadband and my netbook, or do the Updates once at home and move the packages to the other two machines.
I'm using Debian 6.01, Gnome edition, 64 bit, on an Atom N450 netbook, a 3ghz dual core AMD pc and a a 2 ghz single core AMD pc, whatever of this is relevant. They have slightly different programs installed but are at the same stage of not being updated yet, with 252mb of them to add.

I'm planing to get 4 dedicated, remote servers for my start up, the question I have is: how to do only one installation and then duplicate or clone this installation into all the other machines. I could install those 4 servers manually, but the problem is - we have a lot of things that our application needs, and later there will be more servers. So an automatic way to do that would be better. We are using Debian. Perhaps there's a way to create a "big package" that will contain all of the necessary software in it, then simply require from the hosting provider that all of our servers come with Debian installed, and then manually upload the "big package" and install it?

I have three Ubuntu desktops that I would like to upgrade from 9.10 to 10.04. Is there a way to avoid having each PC download the same packages? Is there some magic I can do with two of the PCs to maybe point the software source list at the third 'master' PC that does all the downloading?

I've been having some problems trying to get a new netbook working with China Telecom's 3G service (works wonderfully in Windows, but still trying to figure Ubuntu out), so until I figure out the problem with this Huawei modem, I've written a quick python script to handle updates/installations on the Ubuntu side. (Synaptic does fine on generating download scripts for packages, but it needs an option to handle updates as well)
If anyone else has a use for this, you're welcome to use it. Please let me know what needs to be changed to make it work on your box.

I have a home network with 6+ x86_64 machines, all with similar setups. In the past (FC10 and before), I've had common package repositories (e.g /var/cache/yum/fedora/packages) shared via NFS with all the machines (and with keepcache=1 in /etc/yum.conf). That way, a given RPM only got downloaded once; the other machines would then pull it from my local package repository. And I don't mind the disk usage of keeping one copy of all my old RPMS around.
It seems that while DRPMS is great for a single machine, it doesn't make sense in my case. If I have to download the DRPM 6 times (and take the time/CPU hit to recreate the RPM 6 times), I might as well have downloaded the RPM once and been done with it. Is there a not-too-convoluted method to keep a common package repository across multiple machines even with DRPMS? Or, better, to have that first downloading machine pull a DRPM, generate the RPM, then save the RPM in the local shared repository?

I installed Fedora 15, which was my first real departure from Debian based Linux OSs. I absolutely love the new Gnome 3, and was able to configure F15 to work as I wanted it to. On rebooting I realized that there was no boot loader screen, that F15 just booted and didn't give me a choice as to which OS I wanted to use. Eventually I was able to configure grub to let me see the boot loader and added my old boot loader as a choice. This worked well, maybe not a perfect solution, but it worked. This weekend I installed LMDE (Linux Mint Debian Edition) to another HDD. LMDE uses grub2 and after the install F15 was not recognized.
Two questions: Is there a way for grub2 to see F15? or Can F15 be installed using grub2? I really don't mind re-installing from scratch.

we are having new printers. At the moment we over 1000 machines on multiple sites but no print server they are manually added on the machine ( I know don't ask).
Anyway there is no way they would let use a windows server so the only option I have is to use linux however I little unsure if it is capable of doing the job I need it to do. Basically I want to add the printers on the linux server either using samba or ipp (I would assume samba would be best).
The reason i want to do this is when we have to do around the machines I just want to go around the machines and just the map the printer and it brings down the driver and config etc as we want them to duplex. The issue is I been trying to gain information on the internet and getting conflicting information apparently I can add the windows driver onto the server so when I map the printer it brings it down. However some guides state you still have through the whole process of adding the printer and then choosing the driver etc. Which kinda of makes it pointless to do the printer server since I would already have to do this anyway if we don't have one.
I just want to go be able to go around the machines and for example click star run and do something like \192.168.1.1printer01 and then it done kind of thing.

I have decided to dual boot again because I found a old hard drive laying around.
primary drive: sata 500 gb
ubuntu 10.4 64 bit installed with
boot
[code]...
secondary drive: 120 gb ide drive with xp installed. xp was installed first and wrote the mbr to sda1. I then installed ubuntu 10.4 and it overwrote mbr on sda with grub2. I have tried every combination of the 40_custom script for xp I have found here on the forums but to no avail. The 30_OS probe never seems to see it either. Grub 2 will not see xp. I have it in the menu from the custom_40 but it just reboots the system when I choose it. Any advice is greatly appreciated as I am ready to go back to legacy grub which only took 5 minutes to dual boot last time I did dual boot. I want to give grub2 a chance, since it supposed to be better, but I am getting frustrated.
Here is the output from the boot info script.
Code:
Boot Info Script 0.55 dated February 15th, 2010
============================= Boot Info Summary: ==============================
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #1 for /boot/grub.
=> Windows is installed in the MBR of /dev/sdb

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 wish to setup a network that works like windows but for with lunix of course!. It will need to be able to handle security/DNS/DHCP & Document store from one location. I've been doing some reading and have found that I think I need to be using one of the following:
LDAP
NIS
Kerberos
I have looked at a few Linux based OS's. I did notice that when you install fedora live desktop it gives you the option to connect to one of the above. So I am looking for a complete solution.
1. How to setup fedora to act as server for my needs (or other Linux build)
2. Add fedora/linux mint machines to server to use new security settings. (or other linux build)

I posted this about 3 weeks ago in the 'Desktop' forum and with no replies feel this may be a better area
I've got Karmic installed on my netbook which I understand uses Grub2 which is still a BETA version.
I still seem to have the original GRUB (legacy) within the file system, still have a menu.lst file but is appears to be showing the contents of grub.cfg at boot time.
What is happening at boot time, is GRUB Legacy handing over to GRUB2 at boot or is the an option for GRUB2 to hand over to Grub Legacy.

Here is my current setup. I have installed Windows 7 Home Premium 64-bit, Ubuntu 9.10 64-bit, and BackTrack 4 Final in that order. All operating systems are able to boot and all is working well. The only problem I'm faced with is really just an annoyance. Which is BackTrack is showing up with a "Ubuntu 8.10" entry name.
Now I did some research on this. I found out that BackTrack was based on the Ubuntu 8.10 OS so it makes sense why it would show up that way. I found several articles and topics explaining how to modify the GRUB programming files. I guess to change the entry name, but all of them don't seem fool proof to me nor the best way to go about doing things.
One thing I wasn't able to find info on is where GRUB2 actually gets these entry names from. My theory is if I can find out where GRUB gets this info from, I can simply log into the BackTrack partition and change where the "Ubuntu 8.10" entry is to "BackTrack 4" and then run the update-grub2 command within Ubuntu to update the entry names.

I installed Ubuntu 9.10 & grub2 on a Toshiba sattellite laptop last night:
- Win XP shows up in the Grub2 menu.
- When I boot Win XP, it says autock program not found, skipping autocheck, then Win XP stops booting.
- I did a little digging on the net, & found I have to unhide the NTFS partition for Win XP (hd0,1)
- Grub2 doesn't have an unhide command.
- I tried to run parttool, & got the "command not found".

I installed Fedora 12 on my second drive.
Xubuntu 9.10 is on my master drive, and I use it to install/update grub.
When I installed Fedora, I answered "NO" to installing a boot loader.
After install, I booted Xubuntu and ran update-grub, grub couldn't find (apparently) my new fedora install.
I've tried adding it to /etc/grub.d/40_custom, and when I list /boot/grub/grub.conf, it appears to have added Fedora to the bottom of the menu.
When I boot, it doesn't stop at the grub screen, indicating only one installation of linux.
Here are the pertinent file listings, can you see where I've gone wrong?
Code:
dav@dav-desktop:~$ cat /boot/grub/grub.cfg
#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by /usr/sbin/grub-mkconfig using templates

So I recently tried to install Ubuntu Lucid in the following configuration code...
The installation procedure went fine, and it said it had successfully installed GRUB2. But then, when I tried to boot up the fresh system, GRUB2 didn't even load!!
It's not giving me any GRUB errors, or giving me a 'grub recovery>' prompt, so I suspect that it really isn't even booting into GRUB.
I tried booting into the LiveCD, and installing grub to BOTH /dev/sda and /dev/sdb, but it still does not work, and I am at a loss.
Has anybody else had this problem?

Right I had to uninstall windows xp and install windows 7 to play more games! I use windows to play games and that is it. I have restored grub before and I even double checked with this guide: [URL]
I have two hard drives
sda - 320gb with windows
sdb - 100gb /home
-12 gb /
-480gb (NTFS) shared
However after reinstalling grub it still boots into windows! I will boot into windows properly then shut it down cos its coming up with windows was not shut down properly and if that doesn't work it has then been shutdown properly and I will install grub again.

I have Win 7 in my hard drive (sda) and I installed Ubuntu 10.04 in other hard disk (a usb disk), but when I try to boot my pc from the usb disk (sdb), the grub shell is displayed. No menu is displayed. When I boot Windows 7 from sda, it runs correctly. The problem it's when i wanna boot Ubuntu. I ran bootscript on the live CD and this is what I've obtained:
Code:
