I've recently been having issue with my apt package installer (more details here: I can't use apt install anymore after upgrade). The issue stemmed from my grub, and I fixed it by essentially destroying my grub. This might not have been as much of an issue if I could have fixed it before restarting, but now I'm stuck in windows without being able to access my ubuntu partition.
When starting up, I get a black screen at the moment where I'm supposed to get the grub. After a while it semi reboots and goes into BIOS. I checked, and ubuntu is first in the boot order.
Is there any way I can fix the grub from windows or setup a different grub from windows?
