I’ve got Ubuntu and XP dual-booting on my SATA drive. I went to install Linspire on my IDE drive and it wrote the MBR to the SATA drive with the result that The MBR is corrupted (Grub) on the SATA and I can’t boot XP or Ubuntu . I need to re-install the boot loader. How do I do this without re-installing all Ubuntu? I can get to the grub prompt by pressing ‘c’ if that helps.

Thanks in advance

If you can enter grub, then why you can't boot ????

Anyway, to reinstall grub:
Enter the grub command line and type It should return with something like that: (hd0,5)
If it returns with an error then try: find /grub/stage1
Now type: but change the numbers to match the ones returned by the find command.
If there is no error, type: (that's the string returned by find but without the ",5")
If there are no errors, grub is reinstalled.

I can't boot because the Ubuntu loader has been replaced by the Linspire loader and for some reason the Linspire one lists my operating systems but won't boot to them. I think it's because i installed Linspire on my IDE but my primary drive (in my bios) was the SATA so Linspire wrote the loader to both, (at least that seems to be what happened!!) i can boot to Linspire on my IDE no problem but when i boot the SATA i get the Linspire loader which won't run the OS's.

I am a newbie so i could be talking rubbish of course!

I just want to get my Ubuntu loader back!

Thanks for your help, it worked perfectly!

The problem looks a lot like the one I'm having now. XP on SATA, kubuntu on IDE fully updated and working the way I wanted.Great! After a reboot with the dvd in the drive:boot from first hard drive---> grub error 15. I already changed the hd bootsequence in the BIOS but it still won't work. So can anyone please tell me WHAT worked perfectly as I can't find it on this page?
Tnx
Edit: fixed it by reinstalling Kubuntu on the hda1 partition and booting from that hard disc I read something about that in another thread. So indeed thanks for your help
