Windows won't boot?

I set up my laptop again and after that Windows no longer booted normally. Despite the correct boot order, I can only start Windows by manually selecting the boot manager in the BIOS. When I start the laptop normally there's only a blinking line.

How do I fix the error?

Now,

do you have two Windows versions on it?

Then BIOS does not know which one it should take when starting.

No, I have completely deleted the ssd

Has

you reformatted the?

Or do you have an HP calculator?

I reformatted it

Boot order changed?
