Installstion issues with Boot Camp Assistant

After a trip to the Apple repair store, I'm back up and running. It does seem there is some file formatting differences in Big Sur that can cause problems. They restored my computer to Catalina. Interestingly, they were able to restore using the lates test backup but my photo library wouldn't open in Catalina (possibly also because of different file format?) After installing Boot Camp along with Windows software, I re-upgraded to Big Sur. The only problem I had was that I had to fix my Photos library. I am also able to use Parallels in the Mac OS reading from the Boot Camp drive. Thanks for your help.

After I log into the Internet and get to the recovery options here are a few of the problems:

1. The install OS X takes me to an option to install Mac El Capitan. When I click continue to install I get a message saying “ could not find installation information for this machine. Contact AppleCare”
2. i’ve also tried restoring from a time machine back up. After I enter my time capsule password and hit continue nothing happens.

I’ve tried installing El Capitan using a USB stick used for restoring an old laptop without success.

I think my only option now is to take it in to be repaired 😦

I have a second MacBook Pro but it’s a mid 2009 model. Unfortunately Catalina won’t download because it’s too new for the computer. I’m downloading Sierra and will attempt to put it on a USB drive to install on my iMac. Can I simply move the installation file from the MacBook to the USB drive than boot my iMac from the USB?

Thanks for your help but now my computer is dead in the water. I erased the hard drive and cannot get 0SX installed using recovery. I’ll be taking it in to get repaired.
