Can't Access BIOS after installing Zorin OS

Can I reinstall the OS on CSM Boot mode.

I am afraid I can't help you with an answer to that question, others on here may be able to respond.

In the meantime, maybe this thread could give you a steer in the right direction:

UEFI CSM boot problem

Referencing Cannot boot from USB - sole edit added by moderator I’m having the same problem with my Toshiba Satellite C50-A and I can confirm the issue (in my case) is the UEFI. My Win7(64) is CSM, so if I switch the BIOS to UEFI, Zorin will boot but Windows will not. If I switch back to CSM, Windows will boot but Zorin will not. Someone else I found only needed to reset his BIOS. If you haven’t already ruled it out, it’s worth a try: https://superuser.com/questions/1432795/usb-not-booting-…
