Toshiba laptop wont boot

[Conovore]

I've been trying to fix this laptop, I can go to Bios, and can choose what to boot but i cant boot. i don't care about losing whats on the hard drive i just want to use it. I have a valid copy of windows on usb and key and try to boot from that but it doesn't work. it says "reboot and select proper boot device." I need any advice i just want to use the laptop so i don't care about losing data. I can open the chassis so if i need to tell me
The model is toshiba satellite p845t-s4310

Download and run Seatools for DOS to check the drive health. Run the short drive self test and long generic. Report back with the results.

You may need to go into the BIOS and enable booting from USB or DVD.

UEFI is activated

UEFI has nothing to do with enabling USB or DVD boot permissions. UEFI refers to the BIOS type and hardware that is compliant with UEFI type BIOSs. It has nothing to do with hardware specific permissions for boot devices.
