Need some help setting up 10.04 (Lynx) and GRUB

[Puffie40]

Hey everyone.

I just upgraded to Lucid Lynx, and while everything kernel-wise is running fine so far, I have a problem that is giving me heartburn.

It appears that I have broken my Windows XP boot command, as selecting that boot option will only loop back to the GRUB selection menu.

The Partition is there, and I can access it through ubuntu's file manager, but right now I simply cannot boot into windows.

Partition information: 540gb set for windows (NTFS), 55 set for unbuntu.

Menu Configuration:

### BEGIN /etc/grub.d/10_linux ###
menuentry 'Ubuntu, with Linux 2.6.32-21-generic' --class ubuntu --class gnu-linux --class gnu --class os {

}
### END /etc/grub.d/30_os-prober ###During the update, an autoconfig screen came up asking me to select what I wanted to boot from in GRUB. I selected what I thought referred to the harddisk partitions (and not simply selecting all of them. ](*,)) Is there any way to bring that window back up to change that?

while I am a *cough* Windows power user *cough*, I don't understand ubuntu (or Linux) very well, so please keep that in mind when replying.

Thanks!

Same problem here!

During the upgrade to Lucid Lynx I was asked to choose where to install the GRUB, because I didn’t know what to choose I just followed the instructions and marked all of the options.
Right now the windows XP is in the GRUB list of OS’s, but when I’m trying to boot it – nothing happens (black screen).

Please help.

I had problems with grub2 and windows too. The Windows startup repair in Windows 7 didn't work, so I had to use a rescue disc to boot to the prompt and the run bootrec.exe with one of the following switches:

to fix master boot record: bootrec /fixmbr

to fix boot sector: bootrec /fixboot

to rebuild entire bcd: bootrec /rebuildbcd.

I was able to boot into windows but not into ubuntu.

So I followed these excellent instructions to install grub2 from the ubuntu live cd:
https://wiki.ubuntu.com/Grub2#Recover%20Grub%202%20via%20LiveCD


The more I think about it though I think XP doesn't have the startup repair, but you should be able to run the XP recovery console from disc using these instructions:
http://support.microsoft.com/kb/307654/#3 (scroll up on that page to view the recovery console installation instructions).

Here's a link to the Recovery Console overview, which includes links to pages instructing how to use the Recovery Console and to a list of the Recovery Console commands:
http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/bootcons_fixmbr.mspx?mfr=true

I hope this helps.

Following the instructions in lidsjunky's link repaired the windows boot entry (I was able to do it right in Ubuntu's terminal with the instructions in firefox opened, which is a plus)

I'm relieved it was just a simple boot sector problem. it looks like the entry was miswritten / corrupted when ubuntu was updated.
