This is a GPD WIN (first generation). Power-on and boot-up have been confirmed, but the UEFI Shell screen is displayed after startup. The storage is recognized, but currently, no OS (Windows, etc.) is installed, and there is no bootable system. The buyer will need to reinstall the OS in order to use it. Because there is no OS, only the BIOS/UEFI has been checked. No further operational checks have been performed. The exterior of the main unit shows signs of use appropriate for a used item. Please check the photos for details. This item is being sold as-is (junk). Please purchase only if you are able to reinstall the system, or for repair or parts. Cancellations and returns are not accepted after purchase.
