IPFire 2.27 - Core Update 182 (test) not booting at all

I knew something was wrong with this update when I heard my device beep 2 times instead of 1 time while booting after the update.

It boots directly into the BIOS menu. I have no idea what is wrong. Pakfire messages looked all normal before the reboot.

Did the update change something in the boot partitions?
