Hello, I received my pc reward yesterday, and upon trying to start it up, I was stuck at the UEFI Boot shell. The BIOS detected my ssd but did not show any bootable devices. I tried various things, such as disabling secure boot and unplugging peripherals. I was eventually able to reinstall windows using a flash drive. I am now able to use my pc, but my window is unregistered. Is there any way that I could have the product key that was associated with the pc so that I don't have to buy a new license? Thank you.

Hey, someone will be with you as soon as possible to help figure out what's happening here!
