Pop!_OS on my surface laptop (From windows to Linux). It is the only OS on my system. As the keyboard doesn't work as it should I tried to do the steps from this tutorial. After I completed these steps I did a reboot. After that the system won't boot anymore. I just have a black screen with a non blinking underscore in the top left corner.
After that I wanted to do a fresh install -> plugged in the usb stick from the installation before and reboot the system. But this time the system didn't load the installation, instead it loads
For grub I also looked into several tutorials to get the usb stick booted but I couldn't get it to work. So now I need specific help as I don't know what happened and how to fix it.
I want to do a complete and clean install from the usb stick as I did earlier this day. These are the partitions I have.
(memdisk) (hd0) (hd0,gpt4) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1) (cd0) (cd0,msdos2)
(hd0,gpt2) is the current installation and
(cd0,msdos2) is the usb stick. But I'am not 100% sure.
