Specific configurations of partitions (or rather, byte patterns) are
known to cause some BIOSes to hang during POST - on mine it was Windows
and FreeBSD. If you can, try switching from AHCI to IDE or vice versa.
Otherwise you might have to remove the drive and reconfigure it on
another system with a less buggy BIOS.
