I used the default options during installation. I also used the default partitions created by 'autopartioning'.
I have successfully installed RHEL4, however, after rebooting I get this:
Booting 'Red Hat Enterprise Linux ES (2.6.9-42.ELsmp)'
kernel direct mapping tables upto 10100000000 @ 8000-d000
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz-2.6.9-42.ELsmp ro root=LABEL=/ pci=nommconf rhgb quiet
[Linux-bzImage, setup=0x1400, size 0x195886]
[Linux-initrd @ 0x37f02000, 0xed992 bytes]
Booting the kernel.
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
I am new with Red Hat and would really like to learn. I have searched the knowledgebase and other forums, but could not find any solution. Can you assist me and tell me what I did wrong? or what I should do? I would appreciate any help that you can give me.
The error you get means kernel has no driver for your HDD controller. However, it is preceded by a CRC error. This may mean anything, starting with corrupted install CD, faulty hard disk... Probably HDD controller module is not loaded because some file is corrupted. Hope it gives you some ideas.
Issue has been resolved. There was no problem with the hdd controller nor there was file corruption. I did some tinkering with the grub.conf and found out that there was indeed no mount point for /root. It was pointing to a NULL location.
