Hello, I need to restart my PC from a USB card instead of the C: drive, but I don’t know how to do it: I tried pressing the F8 key during the boot, as I read on the internet, but the selection menu doesn’t appears and the PC restarts normally. I tried to enter the UEFI (BIOS), in the BOOT section, but I can’t find how to set booting from USB. Can anyone help me ? Thank you and greetings Ermanno ---

Try to press Ecs or F7. You can choose boot device in “boot override” ![Untitleaaad](https://us1.discourse-cdn.com/flex020/uploads/chuwi/original/2X/4/4efc0e3ce3e2653a05cd17f7ac3b11b5f04cfcd2.jpeg) ---

Hi Max, thank you; pressing the F7 during the bootstrap key has no effect, Esc open the BIOS window, but in the Save & Exit section, under Boot Override I only seee two options: Windows Boot Manager (P1: W800S 512GB SSD) Windows Recover and no other option relating to USB or SD card. On my very old laptop the F2 key open a window that let me choose the boot sequence, but on Gemibook F2 has no effect. Any other idea ? Ermanno ---

You can try to press all F keys also try fn+F combination. Make sure you have uefi boot usb, this bios may have problem with legacy boot. ---

Is your USB bootable? How ? In the bios you have to enable legacy boot. ---

Enter in the Boot menu. Just put on the first option and press ENTER, then choose “USB…” ---

Make sure your bootable USB drive is connected. Restart and press the ‘Delete’ key over & over during boot-up to enter BOIS. It should show up under the ‘Boot’ tab. Choose it and press ‘Fn’ and ‘F4’ to exit into the USB drive. ---

Mine automatically boots from USB drive (UEFI bootable). I suppose, that its firmware can’t boot legacy (MBR) OS media.
