Assuming you are booting with grub2, you will need to use /dev/sdx in
the grub2 configuration file. This is known issue with grub2. Example
from my script:
--------------------------------------------------------------------------------------
echo 'Loading Linux desktop ...'
linux /vmlinuz-desktop root=/dev/sda7 ro splash quiet
echo 'Loading initial ramdisk ...'
initrd /initrd-desktop.img
---------------------------------------------------------------------------------------
