Help disabling Intergrated GPU on MBP 2011

[u/s1neztro]

Hey y'all!

I tried installing linux mint onto a 2011 mbp with an i7 and a failed/ failing amd gpu.

Currently my installation fades to white when I boot and then it hangs until the laptop shuts itself off

I've tried repairing the installation but that didn't work(?) (i can post the log when i get home) it said somewhere that the efi is locked

I currently can't seem to get grub to initialize when booting (its just holding e after the chime right?)

Any ideas on what to do?
