Trouble with Windows after switching from Linux..?

Question

linux

Huh, in general, I climbed from Windows to Linux, I didn’t really like it), and decided to go back, but after installing Windows on reboot, the laptop turns on, the company lights up, and then a black screen and an underscore blinks in the upper left corner ...
I don’t know what to do, please help.
I formatted the partition with Linux and installed Windu on it, maybe something is wrong with the partition format ...
There is an option that hdd flew, but there were no oddities with it earlier during work, so this is unlikely

Answer 1

Perhaps after installing Linux, the disk format changed from mbr to uefi. Did you install Linux mint?

Answer 2

Have you tried resetting BIOS to default?
