[SOLVED] Mint 20.1 64bit only boots into busybox/initramfs

After reinstalling Mint it won't boot from SSD, instead displaying GRUB menu before entering busybox. It did work with same hardware before reinstallation, however in BIOS mode instead of UEFI.
Live session works perfectly fine.
Boot and EFI are the same partition (/dev/sda2)
Root partition is separate (dev/sda5)
Motherboard model: MSI B450 Gaming Plus

I found many solutions online but none of them work. Fsck doesn't do anything. Switching from UEFI to legacy mode or reinstalling Mint don't help either. Boot repair detects the boot partition as a windows partition for some reason and refuses to do anything.
Recovery mode shows some extra info:

Code: Select all

Target filesystem doesn't have requested /sbin/init.
BusyBox v1.30.1 (Ubuntu 1:1.30.1-4ubuntu6.3) multi-call binary.
Free initramfs and switch to another root fs:
chroot to NEW_ROOT, delete all in /, move NEW_ROOT to /,
execute NEW_INIT. PID must be 1. NEW_ROOT must be a mountpoint. 
No init found. Try passing init= bootarg.
While it is a set of instructions, i have no idea what am i supposed to do and what's the problem.

Do you mean they are separate and on the same partition? I'm not sure why you are referring to them as separate names. The EFI partition is where the bootloader is when you boot EFI mode. That is the "boot" partition.

You indicate you can boot to a live session. Can you check your partitions on GParted to let us know what it shows?

I somehow got it to work by wiping the drive and reinstalling several times while desperately trying any solutions to similar problems found online. Honestly not sure what fixed the issue. Sorry for not replying earlier.
Marking as solved i guess?
