Does the boot option represent the partition where / root and /boot are
located. I ran into a similar problem when doing upgrades. Hd0,1 was
swapped for hd1,1 in the boot list. When the list is show at boot
highlight it and hit e for edit twice and change your numbers around to
see if you can get it to boot. The changes you make won't stick so if you
can get it to boot you'll have to remember what you changed it to. If I
knew exactly how you configured your disk I could tell you exactly what
you needed to do. Here is my boot config;

title Ubuntu 7.10, kernel 2.6.22-14-generic
root (hd0,1)
kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=c84c97ef-c126-427f-81a0-da6482e5ed1f ro quiet splash
initrd /boot/initrd.img-2.6.22-14-generic

Windows is the first partition hd0,0 (not shown) linux is the second hd0,1.
If yours is the same then change it to hd0,1.
