At what point in the boot process does the boot fail (BIOS, grub or
kernel)? What sort of error messages do you get when the boot fails?
Give us a clue, what actually happens?
FWIW fstab is irrelevent for a boot failing. The kernel gets its root
partition from the grub command line in grub.cfg and mounts that read
only. /etc/fstab comes into play later when the bootscripts do their
work.
