Black screen after installing nvidia drivers

I can’t access the BIOS, the screen glitches and stays black.

I kept Windows in case I’d need it for anything but actually haven’t used it since Manjaro. I’m thinking if there’s an easier way of fixing this e.g. replacing Windows altogether. Just mumbling here.

Trying different Kernels now

Installing kernel gives me error: no targets specified

I tried something I found in another thread:

grub-install --recheck --no-rs-codes update-grub

Gives me

Installing for i386-pc platform.
grub-install: error: cannot find a GRUB drive for update-grub.  Check your device.map.

This is from the USB iso chroot

Nothing seems to work and I’m running out of options. I did a separate partition for /home, so I should be fine reinstalling and maintaining my configs and files?.

From this post

New x86 PC preloaded with Windows 10, want to overwrite - #11 by stephane

try before to update bios & firmware if possible
you will have to check all options in bios for a boot EFI

  • no secure boot
  • no fast boot
  • no csm
  • no Legacy
  • UEFI on others ( not windows )
  • disks on AHCI ( no raid )
  • no optane

for check before installing , open a terminal

inxi -Fza 
sudo parted -l
sudo efibootmgr -v
test -d /sys/firmware/efi && echo efi || echo bios

use Gparted to format in GPT , you will need a /boot/efi fat32 ( 33Mo) with flag boot & esp
( can be added by Gparted )

I don’t have access to bios for some reason. I remember having setup “boot from USB whenever connected” when I had access a while back so that should be fine?

Since I have Windows in my SSD and Manjaro in my HDD I would like to get rid of Windows altogether and have Manjaro there instead. What is correct way of doing this on GParted?

Would my new Manjaro installation automatically recognize packages in /home?

Any other things to consider?

Thanks a lot for the help so far!
