"Invalid format" when trying to boot into Mint 20.3

Post by Angvs »

I have an encrypted Linux Mint 20.3 partition installed on a dual boot alongside an unencrypted Windows 7 partition.

Today I started my computer as I do everyday but, after I typed the encryption key, instead of proceeding to Mint's log in screen, my monitor simply went black and displayed the message "invalid format". I tried Boot repair, resetting the BIOS to default settings and even re-installing Mint via the USB stick, but the problem persists. It only starts on the recovery mode of the live installation. Windows starts normally.

I suppose some system update I did yesterday messed up with the resolution or something, but I have no idea how to fix it.

Recovery of encrypted partitions is tricky.You should avoid it. I hope you have backups in case of the worst scene.
Please see viewtopic.php?f=42&t=315207

Good luck.
