Hello, thank you for reaching out to Microsoft Q&A.
- May I please know the make and model of your device?
- Did you make any recent system changes to your device, such as updating Windows or BIOS?
I understand that you’re encountering a “No Bootable Devices Found” error. This issue can occur if the hard drive is not being detected, if there have been recent changes to the BIOS settings, or if the operating system or installation media is corrupted.
- First, boot your PC into the BIOS Utility screen. (usually by pressing Del, F2, F10, F12, or Esc during startup - the key varies by motherboard manufacturer, so check the documentation)
- Navigate to the Boot Order section and check that the Boot Priority is set to 'Windows Boot Manager'.
- In the Boot Configuration window, check whether Boot Mode is set to UEFI only and that your Hard disk is detected in the Boot sequence section.
- Save the configuration and click Exit.
