I recently downloaded and installed BO dated 6/7/11 (the date when I installed the latest BO)

The install went fine.  No errors indicated.

When I rebooted I get this message;

-------------------------------------------------------------------------------------------------------
VFS: Cannot open root device "VolGroup00/root" or unknown-block(0,0)

Please append a correct "root=" boot option

Kernel panic - not syncing
-------------------------------------------------------------------------------------------------------

The Dell Dimension 2400 uses standard IDE drives --- not SATA type drives.

I changed the drive to be master instead of cable select.  The drive is on the IDE0 controller.

Any suggestions would be greatly appreciated.

Thank you,

Hello,

First of all, I would boot the system using a live CD. In the live CD, I would run "lsmod -k" and see all the drivers in use. Run "dmesg" and maybe try to "chroot" and check the disk devices and compare it with the grub or lilo menu and under /etc/fstab.

For example, if under /etc/fstab the / is mounted to /dev/sdx and your hard drive is seen as hdax you will have kernel panic.

Live CD will help you figure out what is going on.

Good Luck.
