View Full Version : [ubuntu] After reinstalling Windows, cannot restore GRUB

Well I'll give a brief rundown of how my morning's been: LONG

Now that, that's out of the way let's get down to business. My XP installation caught a cold via an advert on an anime site I frequent (Bleach fan). So I formatted the partition and reinstalled windows XP home edition 32-bit.

I made the mistake of filling the drive to capacity (which is a no-no apparently if you want to be able to use gparted). I just so happen to have had 2 other small ubuntu installations from previous experiments, so I deleted them and that enabled gparted to work again.

The problem I am having however is when I try to re-enable GRUB using the steps listed here (https://help.ubuntu.com/community/WindowsDualBoot).

Finding the stage1 designation following those steps led me to know that my hd's marking was (hd1,5). I got all the way through the steps and received an error on the last line after running the command: setup (hd1)

The error ran as follows:

Running "install /boot/grub/stage1 (hd1) (hd1) 1+17 p (hd1,5)/boot/grub/stage2 /boot/grub/menu.lst"... failed

Any thoughts?

Let's get a better look at your setup & boot process. Boot the Ubuntu Live CD/USB. Choose "try ubuntu without any changes", when the desktop loads come back here and do the following:

1. Download the boot info script. There is a link in my signature.
2. Once downloaded move the boot info script to the desktop.
3. Open a terminal and run the command
sudo bash ~/Desktop/boot_info_script*.sh

This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

See here (http://bootinfoscript.sourceforge.net/) for more info on the boot info script.

Above link is to meierfra's Sourceforge web page.

I would put GRUB on MBR of sdb then make sdb first disk to boot in the hard disk boot order in BIOS. Then boot into Ubuntu and repair the MBR of sda to a windows MBR.

First reinstall GRUB on MBR of sdb. Boot the ubuntu 9.04 Live CD/USB & choose "try ubuntu without any changes." When the desktop loads open a terminal and do this:

1. Type sudo grub. Should get text of which last line is grub>
2. Type "find /boot/grub/stage1". You'll get a response like "(hd1,4)".
Use whatever your computer spits out for the following lines.
3. Type "root (hd1,4)"
4. Type "setup (hd1)", to install GRUB to MBR
5. Quit grub by typing "quit".
6. Reboot and remove the bootable CD.

Go into BIOS and set sdb (640 GB) disk as first to boot in the hard disk boot order. Save changes to CMOS and continue booting. Choose Ubuntu from the GRUB menu. When the desktop loads open a terminal and run
gksu gedit /boot/grub/menu.lstThat is a lowercase L in .lst

I get an error at the very end of the grub command line instructions, I'm posting a screenshot of it. I will continue on past this and see if it works still, but previously when I got this error Grub gives an error that it cannot load my partition. I will post again shortly with the results of continuing these instructions. Thank you again for your time, patience and help!

Ok after finishing the grub commands I rebooted and changed the boot sequence. Upon doing so, Grub comes up and freezes at:

GRUB Loading stage1.5

Quick update:

I can log into the partition using the Super Grub Disk, however if I do not use it I get errors in GRUB.

Extended partition linking to another extended partition

Your partition table is slightly messed up. But it should be easy to fix. Boot into Ubuntu with Supergrub



sudo fdisk /dev/sdb

Press "w". That rewrites the partition table. Reboot (using Supergrub) so that the changes take effect. Then use presence960 instruction to reinstall Grub.

Somehow or another using supergrub to load again resolved the issue, Grub's back up and working for booting into both Ubuntu and XP. Thanks much for all the advice and help! I'm defintely glad I joined this forum, and I will be taking down notes of all of this as well.

Ubuntu for life! :guitar:

Yes, if you use SuperGrub to install Grub to the MBR you are able to boot. But your partition table is still messed up (for example gparted will see your whole hard drive as unallocated) So I recommend to carry out my instruction from my last post.

I will still follow those directions, I have to run to the store for a bit but when I get back I will run the fdisk command. Yeah I was a bit surprised that gparted can still see my partitions (I figured my partition table was wonky with all the tinkering I've had to do yesterday and today).

Thanks again so much! I went through and did the fix in order to fix the partition table and everything's smooth (in addition to a non-cluttered GRUB menu). Off to go finish installing windows apps and then back into Ubuntu \\:D/
