You only half quoted me. I gave your procedure as an alternate procedure,
but you didn't quote that part. The procedure that I suggested
to try first is superior, in my opinion, because, if it works,
it allows him to boot his full production system (X and all). The rescue
CD essentially becomes a portable bootloader. The chroot procedure
can be used as well, but a rescue CD which runs the same exact
kernel that he has installed on his hard drive and which is booted
with "root=..." pointing to his permanent root file system essentially
becomes a portable boot loader, allowing him to boot his full
production system.
