Grub gives Error 13 when trying to boot Windows XP

[draco]

After installing Gentoo Linux, I tried to boot back into windows but got this error message:

Error 13: Invalid or unsupported executable format

Output of fdisk -l

Device Boot Start End Blocks Id System

Sorry it looks so bad.

I have this as my grub.conf file

please confirm which partition equates to your WinXP C: drive.

At the moment grub is looking at /dev/hda2 for the C: drive , is this correct (remember that grub counts from zero and not one).

{b]If[/b] your C: drive is the fat32 partition - /dev/hda1 - then grub needs to point at (hd0,0) (ie. 'rootnoverify (hd0,0)' ).

/dev/hda2 is the windows C: drive, the reason why /dev/hda1 is fat32, is because my computer only came with HP Recovery CD's, and I couldn't choose which partition to install Windows on, it just automatically did it and added an extra HP_Recovery partition for some reason.
But yes, /dev/hda2 is supposed to be C:

what haapens if you put 'rootnoverify (hd0,0)' ?

I know what will happen, it's not a bootable partition. I use /dev/hda1 to transfer files between Windows and Linux. (Before, I was using SuSE). But I got it to boot... I'm not sure what I did for it to work though.

You really dont need that makeactive statement, but does no harm. Why dont you give setting rootnoverify (hd0,0) a try. From looking at fdisk output I see that the first parition is very small, bout the size of a boot partition maybe?. It could be that windows xp has the boot information on that partition, in which case you need to boot to it.


Also, check /boot/grub for the correct stage files. I cant remember which one boots windows but its probably fat_stage1_5.
