RHEL 4/USB hard drive
I am trying to boot RHEL4 which is loaded on a USB hard drive. I have GRUB installed. On power on, GRUB starts loading and all of a sudden it gives an error saying unable to mount the partition, press any key to continue. Upon any key stroke, it takes me to a window where I could select "RHEL 4" to boot, which takes me back to the GRUB. I tried to load the kernel and initrd manually from the GRUB prompt and boot the kernel. It says it cannot mount the partition and throws a Kernel Panic - Error mounting VFS.
Can anybody give me some ideas on how to troubleshoot this?
boot up in 'linux rescue' mode through Installation CD/DVD and post the contents of /boot/grub/grub.conf and /boot/grub/device.map files.
you can use any LiveCD too.

Here are the two files. Thanks for your help.
grub is installed on internal drive. first of all remove that. boot up from Windows Installation CD, select 'repair' and execute 'fixmbr'.
Plug-in External Drive as Primary Master and 'First Boot Device' in BIOS. boot up from RH installation CD/DVD and execute this code at boot: prompt
press Ctrl+D two times.
grub-install /dev/sda --recheck
