GRUB problems on dual XP+Ubuntu install NC8000 internal+multibay
I have an HP NC8000 with Windows XP (all SPs) installed on the primary drive and Ubuntu Feisty installed on a removable multibay drive.
With the removable multibay drive inserted I can boot into GRUB and choose my operating system and eveything works fine however when I remove multibay drive (to make room for a 2nd battery) I can no longer boot into XP (GRUB Error 21). Looking through the forums here I've got an idea of how I might remedy this (repair MBR using XP installation or SuperGRUB) but I'd like to know what the error is and how I might be able to get my dual XP/Ubuntu configuration working properly... Any takers? I've tried reconfiguring GRUB using the following procedure: sudo grub root (hd0,0) setup (hd0) quit However I cannot execute setup (hd0)... I think the problem may be that I cannot see my Windows partition from Linux (or vice versa for that matter)... I am appending my /boot/grub/menu.lst for reference: # menu.lst - See: grub(, info grub, update-grub( # grub-install(, grub-floppy(, # grub-md5-crypt, /usr/share/doc/grub # and /usr/share/doc/grub-doc/. ## default num # Set the default entry to the entry number NUM.

That being said, I'm impressed with Ubuntu thus far but need to have access to my XP installation standalone... I can configure my BIOS to prompt me as to which drive I wish to boot into but atm GRUB doesn't allow me to boot my internal drive standalone... Any takers? |
I've just figured out how to list out my partitions (go newbie!)...
Disk /dev/sda: 100.0 GB, 100030242816 bytes 240 heads, 63 sectors/track, 12921 cylinders Units = cylinders of 15120 * 512 = 7741440 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 12921 97682728+ 7 HPFS/NTFS Disk /dev/sdb: 60.0 GB, 60011642880 bytes 255 heads, 63 sectors/track, 7296 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 * 1 6992 56163208+ 83 Linux /dev/sdb2 6993 7296 2441880 5 Extended /dev/sdb5 6993 7296 2441848+ 82 Linux swap / Solaris ... it would seem that sda1 is my XP installation and sdb1 is Linux... given this info can anyone clue me in to how to fix GRUB so that I can boot into XP (sda1) w/o my multibay drive installed... ie how to get GRUB installed entirely on the sda1 drive? |
