Re: Compaq 5300 with RH7.2 using Grub

[Hari Narayanan]

If you can boot with the Old Kernel (using the same grub.conf file),
then the problem is not in Grub, but in your kernel. Looks like
the kernel is booting up fine. You seem to have missed out some
options in your kernel. So the kernel craps out. You are already
past Grub.
