Here's my situation:
I installed Ubuntu on my work laptop on a partition before IT implemented whole hard drive encryption via bitlocker. I had to do some quick work when IT announced they were using bitlocker because GRUB was causing problems. In order to fix the issue, I removed grub and reinstalled the windows boot loader.
EDIT: I can't simply re-install GRUB because it would most likely lock me out of my windows partition.
I can't figure out how to boot back into Ubuntu now that GRUB is gone. I know that the Ubuntu partition is not encrypted, because I saw it when I booted from a live USB.
Ideally I would like to have a USB boot option to select Ubuntu instead of overwriting anything.
So what can I do here?
