I pressed off while resetting the laptop, what should I do?

So it was me: I reset my laptop like every month, but this time I accidentally switched off my laptop when I reset it. I thought I could start it again and everything would be normal. But no, the laptop has been restarting every 30 seconds for 3 hours and I can't do anything. Could someone please help me? LG zion

I destroyed the bootloader

Reinstall Windows, that should work.

Assembler has a knot in its stomach

Get a stick, set up the Windows installer on it, and try the repair option.
