Hello, It sounds like you forgot to label your / partition (/dev/sda2) as "/". As a workaround, interrupt the grub loader and edit the boot command line from kernel /vmlinuz-2.6.9-42.EL ro root=LABEL=/ rhgb quiet to kernel /vmlinuz-2.6.9-42.EL ro root=/dev/sda2 rhgb quiet you should then be abble to boot the kernel and get a minimal shell, but probably failed to mount "/" ie finish the boot process : /etc/fstab may also mention "LABEL=/" instead of "/dev/sda2" for / FS. To fix it, 2 solutions: * once booted, (mount and) modify /boot/grub/grub.conf to modify the kernel boot parameters as did to boot and also the /etc/fstab. * or label your root partition as "/" to match the kernel options in grub. the command to do it is: e2label /dev/sda2 "/" I'm not sure you can do it on your running system (ie /dev/sda2 mounted), you should use a rescue system to do it.
