Chosen Solution
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, Antonio
Check your keyboard input: Preferences > Keyboard click on Input sources make sure you have the correct keyboard listed in the left column (U.S.) @abasilio To see what your drives are its easier to access your System Report via About This Mac. Now drop down to the USB to access the thumb drive, here I’m accessing a FireWire drive
And here I’m accessing the internal drive
Within Disk Utility you must alter the View to ‘Show All Devices’ Then you should be able to see the top level of your drive, In my case that would be the Samsung SSD and clicking on erase to clean things off when you add the partition you’ll be able to select the format of the partition.
