Big time problem after trying to install Big Sur update

Hello,

Yesterday I tried to install this Big Sur system update. At some point it wanted to restart the computer and after that there came quite a long loading screen with lots of waiting time. I went to sleep and for my surprise it was still in the same loading screen with ”less than one minute remaining” when I woke up and nothing happens. I have tried to reboot the system but it gets stuck in the same sitiuation after 25 minutes. Now I am basically stuck in this endless boot-loop.

I have tried some different reboots when holding some keys, but they wont work either. I can get to this hard disk / target disk mode or restore point to year ago but that is it. Any suggestions what to do? This is very frustrating.

You should move your question to MacOS tag. iOS is not the right tag.

You should not restart during system update, even if it seems to be very long. You risk to corrupt badly the installation.
