Switching Back to windows

Hello everyone! Hope you all are doing well.

Im having trouble switching back to windows after installing Ubuntu. I had switched to Ubuntu after updating my computer from Win 10 to Win 11, and it was giving major problems. When playing videogames or using blender, after like 30 minutes my entire computer would begin to lag real bad, im talking like 5 fps through out the entire System except the mouse for some reason, the mouse moved around the screen like butter.

Anyway, I just want to switch back to windows, I tried to install it the regular way via usb but none of my storage devices are recognized when in the windows set up screen.

Im not too knowledgeable about this stuff and I want windows 10 back as I barely have time throughout the day and I just want my computer to work with the applications I use.

Thanks in advance. Also sorry if this is posted with the wrong tag.
