hda died, moved hdb to hda-->> kernel went crazy. Help

[Antonio Rodr008 <arodriguez31@cfl.rr.com>]

Hi all, I had in my other computer a dual booting, win98 in hda, testing in hdb. Then hda died, so I removed it, and put hdb as hda. So now the kernel goes into panick, somewhere it has written hdb, but hdb doesn't exist anymore. I have got in using the rescue CD woody cd 1, booting with rescue root=/dev/hda1 but I don't know what changes must be made.
Can some point to the needed changes? I would like to avoid a whole new installation.
Thanks.
