Thanks for your reply. Here is my situation. My original disk has 3
partitions : /boot, / and swap.
It failed. I use a new drive and re-create 3 similar partitions but may be
with different sizes because I do not remember exactly the size of /boot and
/ then I install Linux ( RHE 3 in this case ) with minimal configuration.
Then I do a full restore of the tape that include /boot and other
directories as /usr , /lib, /etc  ...( except /dev, /mnt, /proc ).

When I restore everything from tape ( including the /boot ) and reboot from
the hard disk, the server reboots and display only "GRUB" with the flashing
cursor right there. It hangs right there.

When I restore everything except /boot, then the server is booted normally
from the hard disk. And in this case, the kernel is the one that the RHE 3
CDs has.

I mentioned old and new kernels because on the original drive, I ran the RHN
update to some new kernel. The tape does have this new one.

GRUB is installed onto MBR.


Thanks,

Vu
