Restoring GRUB to MBR

slidermsu · 01-08-2006, 05:03 PM

I've looked at some other threads, and when I had this problem before, I followed instructions from the Ubuntu Starter Guide, but couldn't get it to work, so I'll lay out the setup and all here.

Four partitions:
/dev/hda1 (WinXP, NTFS)
/dev/hda5 (just my files, NTFS)
/dev/hda6 swap
/dev/hda7 / (ubuntu 5.10)

During Ubuntu installation (performed after XP installation), I let it install GRUB to the MBR. Now, I am preparing to reinstall WinXP, but I'm not exactly sure how to get GRUB re-installed exactly the way and location it is now once I've reinstalled XP. Note: I do have an Ubuntu Live CD. Could someone give me some direction here?

Restore GRUB quite simple in Ubuntu, instead going through all the "gain root access" and play with shell commands, you can use the Ubuntu installation CD to restore it without going through all kinds of hassles.

Here are the steps:

1. Boot your computer up with Ubunto CD
2. Go through all the process until you reech "[!!!] Disk Partition"
3. Select Manual Partition
4. Mount your appropriate linux partions

/
/boot
swap
.....

5. DO NOT FORMAT THEM.
6. Finish the manual partition
7. Say "Yes" when it asks you to save the changes
8. It will give you errors saying that "the system couldn't install ....." after that
9. Ignore them, keep select "continue" until you get back to the Ubuntu installation menu
10. Jump to "Install Grub ...."
11. Once it is finished, just restart your computer

Good luck!.
