Ok, I'm still in the weeds. When I boot with the BT4 USB, my HDD becomes /dev/sdb, so I think that's causing problems with LILO
1) I edit lilo.conf to sdb so that it works when I load it 'lilo -v'...but when I reboot, it's now sda, so that didn't work (panic)
2) I edit lilo.conf to sdb, load lilo, then edit conf back to sda...doesn't work, same kernel panic
3) I install nUbuntu via the Ubuntu installer, (w/GRUB)...all is well. So I tried just taking the existing partition structure and installing the various BT folders/files...ended up getting GRUB error 17...tried editing default.cap to no avail.
4) Tried sticking with the install guide, inserting some GRUB language:
(for full disclosure, my vista partition is /sdb2, so my boot partition is 1, swap is 3, rest is 4, but I've tried so many alternatives (extended partitions, no swap) that I think the issue is with the boot loader. This time I got GRUB error 22.
# mke2fs /dev/sdb1
# mount -t ext2 /dev/sdb1 /mnt
# grub-install --root-directory=/mnt /dev/sdb1
# umount /mnt
Last comment: I do have a nUbuntu USB, and when used, the usb is sdb, HDD is sda...is there a way to edit SOMETHING on the BT usb to direct this assignment? I did try reordering my boot order in BIOS but nothing changed.
Also, no CD drive available so when I get to the point where I really need to get to vista, I just boot to nUbuntu, clear partitions with fdisk, then go back to the installer...grub sees vista just fine and I'm in business...but I want to be in business w/BT4, not nUbuntu.
