How to put Windows instead of Linux?

Question

linux

(Perhaps a stupid question, I know) I decided to master Linux, installed ubuntu, and instead of installing ubuntu along with windows, I erased the completely old OS, now when I install Windows from a USB flash drive, it always knocks out a Boot error, I searched everything in the BIOS, I know that on Linux, a different file system, tried to share a disk with the ntfs system, nothing happens

When I put Windows from a flash drive, it always knocks out the Boot error

Apparently, the BIOS does not see a device from which to boot. Either you wrote the bootable USB flash drive incorrectly, or the boot from the USB flash drive setting is not enabled in the BIOS or it has the wrong priority over the broken bootloader on the hard drive.
It has nothing to do with it at all.
