Unable to use boot key combinations
Hi, I’ll try to explain all details so that somebody is able to help me, hopefully:
I own a MacBoor Pro 15’’ Retina Late 2013. I’ve replaced that SDD with a new 2TB one. but that time I was using Mac OS Catalina. right after that I installed windows 10 using Bootcamp. Some time later I’ve upgraded to Big Sur and everything continued working fine.
Recently I had some issues with windows due to being testing a lot f experimental software. so I removed BootCamp to be able to reinstall Windows 10 again using Bootcamp. But Windows 10 installation doesn’t start and the screen stays black for hours.
To try and overcome that I decided to try to go back to Catalina as with that version I never had any issues with bootcamp. But after created the USB installation media (MAC Extended Journaled) I’m not able to boot it. Neither through System Preferences -> Start Up disk nor through Start Up manager. I’m not able to go to Startup Manager as no Start Up key combinations are working, apparently. Eventried to reinstal from Internet Recovery but it always boots to the OS.
During all those actions I also realised that it seems that I have no recovery partition.
Thanks in Advance,
Is dit een goede vraag?
