Hey Abula7,

To clarify, are you able to enter macOS Recovery?: Use macOS Recovery on a Mac with Apple silicon - Apple Support

If you can, try these steps: Create a bootable installer for macOS - Apple Support

"Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing. (A bootable installer doesn't download macOS from the internet, but it does require an internet connection to get firmware and other information specific to the Mac model.)
Turn on the Mac and continue to hold the power button until you see the startup options window, which shows your bootable volumes.
Select the volume containing the bootable installer, then click Continue.
When the macOS installer opens, follow the onscreen installation instructions."

Let us know how it goes! Take care.
