It’s possible that your computer’s hardware is still functional, but you’re unable to boot into Windows. Perhaps the bootloader is corrupted, preventing you from booting Windows. However, if the computer is still functional, you can use it to boot into a different Windows environment that will (hopefully) allow you to retrieve your data.

You can make use of a bootable USB drive connected to Windows. Download and launch Microsoft’s Media Creation Tool on that PC, then choose ISO when requested.

Then, open Rufus and pick your USB drive under “Device,” your Windows ISO under “Boot Selection,” and Windows To Go under “Image Option” from the drop-down menus. Wait for the process to complete after clicking Start. Follow similar instructions for operating macOS on a USB device if you’re using a Mac.

You can restart your computer once it’s finished. When you view the starting screen, press a key on your keyboard to enter the boot menu—it will generally inform you which key to press on-screen. For example, at the startup screen on the computer, click F11 to open the boot menu, to boot your laptop/Windows PC into a Windows environment.

If it doesn’t work, you can access the BIOS configuration by pressing Delete or F2 on your keyboard. Locate the “Boot Order” box, then drag your USB drive to the top of the list.
