Bought a new Macbook M1 but can’t reinstall Big Sur

I just bought a new Macbook Pro M1 2020 but after booting it with backup data from time machine, it’s really slow and freeze a lot. I decided to just factory reset everything and reinstall the Big Sur.


Here comes the problem. I erased the HD and Data but when I wanted to reinstall the Big Sur, it took very long to install, the bar even shows “8 hours and ___ minutes remaining”. Decided to wait about an hour but the estimated time remained the same.


Can anyone help?
