VVAW,
Yes, you need to edit the grub menu before it boots. It's pointing at the old partition (/dev/sda1), but now it's on the new one (/dev/sda2).

When you select "Ubuntu" you'll see the grub menu. Hit 'E' to edit the first entry, and change it from:

Code:

insmod part_msdos
insmod ntfs
set root='(/dev/sda,msdos1)'
search --no-floppy --fs-uuid --set=root A4AAC4A2AAC471FA
loopback loop0 /ubuntu/disks/root.disk
set root=(loop0)
linux /boot/vmlinuz-2.6.38-13-generic root=UUID=A4AAC4A2AAC471FA loop=/ubuntu/disks/root.disk ro quiet splash
initrd /boot/initrd.img-2.6.38-13-generic

To:

Code:

insmod part_msdos
insmod ntfs
set root='(/dev/sda,msdos2)'
loopback loop0 /ubuntu/disks/root.disk
set root=(loop0)
linux /boot/vmlinuz-2.6.38-13-generic root=/dev/sda2 loop=/ubuntu/disks/root.disk ro quiet splash
initrd /boot/initrd.img-2.6.38-13-generic

Then Ctrl+X to boot. After booting update the grub menu:

Code:

sudo update-grub

Note I also deleted the line 'search --no-floppy' (not critical, but it will probably pop an error msg if you leave it in).

Thank you very much it worked..

I have one question if I were to upgrade my laptop to say i7 8 gig. Could I move the root file and boot my wubi install .

Just do the same steps above

thanks again

You can move wubi installs between computers. only issue is if you have a custom graphics driver, or try to run a 64-bit install on a 32-bit architecture. This thread is about migrating from wubi... and that's what I'd recommend. Wubi works great but there are too many corrupt root.disks out there for my liking and for that reason I'd recommend the dual boot route.
