[Satyajit Das <satyajit@spnetctg.com>]

I have 6.4GB Harddisk.
Hda1 --- > Win98  ( 1800 MB)
Hda5 --- > RedHat 6.1 Kernel : 2.2.12-20 (1700MB)
Hda6 --- > Swap (133MB)
Hda7 --- > Storm Linux -2000 (2510 MB)

Firstly I install Win98 > next RedHat 6.1 > at last  Storm Linux.
My problem is now I'm not able to boot Red Hat linux.
only boot win98 and storm.
Installation period, I use Lilo  boot loader in MBR ,I give level
hda1 for win98, hda5 for red, hda7 for storm linux.

please help me how can I solve this problem, waiting reply urgently
because I have so many important files and email.
