There’s something strange happening as your filesystem gets mounted read-only and thats the reason your system does not come up.
To get more information, we need a complete log of whats going on during boot. The easiest way to archieve this, is to:
- Enter the Bootloader by holding Shift (BIOS-Boot) or ESC (UEFI-Boot)
- Press E to edit the default boot entry.
- Remove
splashandquietfrom the boot list (navigate with cursor, remove with backspace):
- Boot with F10 and record the entire boot sequence with your mobile phone. You should now also see the very early boot messages.
Is there anything interesting in? Something with can help us analyze the problem?
