GRUB dual-boot 32/64bit RHEL ES

[Marcelino Mata]

I believe the /etc/fstab will also need to be updated to reflect the new
e2label label....or remove the labels from menu.lst and fstab.  Labels
can a be pain with dual/triple boot OS installs.

Example of menu.lst without label:

kernel /vmlinuz-2.4.21-32.ELsmp ro root=/dev/sdc1 hdc=ide-scsi
