win98, winxp and rh7.3 in a box prob

I got a problem here...

I have a pc with a win98 and win xp os installed... Then i put a linux Redhat 7.3 in another partition...
After that, i set up the GRUB so it can access all the 3 os... everthing is ok, except the winxp, where i cann't run it.. the winxp started but it has start up checking error (after that it will automatically halted the pc)...

any one have any ideas to solve that?

Hmm.. another one, what is the command should i put to mount ntfs partition within the root?..

thanks.

i suppose u want to mount C:\ in /mnt/win_c/ then the entry in ftab file will look like (as is mine)
/dev/hda1 /mnt/win_c/ ntfs iocharset=iso8859-1,ro,umask 0 0 0

well your other prblem is not very clear try to explain it in more detail along with the error messages(if any) you are getting
