Fixing “Reboot and select proper Boot Device” on Windows

Fix #1: Check Boot Order

The easiest fix for the “Reboot and choose proper Boot Device” error is to ensure your computer’s boot order correctly lists your hard disc as 1st option.

To check the boot order, follow these steps:

1. Restart your computer
2. Press the required key to open the BIOS menu. This key depends on your computer manufacturer and computer model. This is usually listed on the primary screen that appears on your monitor. It is often any of the following: Esc, Del, F2, F8, F10, or F12. If your screen shows multiple keys, find the key to open “BIOS,” “setup,” or “BIOS menu.” The boot order is modified from here.
3. Go to the Boot tab
4. Change the boot order and list your computer’s HDD first
5. Save the settings
6. Restart your computer

Fix #3: Disable Legacy Boot (UEFI only)

On computers that have UEFI rather than BIOS, having the Legacy mode option active could cause the “Reboot and choose proper Boot Device” error to seem.

If that’s the case, you’ll disable the Legacy mode and restart your computer:

1. Restart your computer
2. Open the UEFI menu by pressing the required key. This relies on your computer manufacturer and is listed on the primary screen that appears on your computer. It is often any of the following: F2, F8, F12, or the Del key.
3. Switch off the Legacy option. Counting on your computer model, this will be listed at the safety tab > Legacy Support.
4. Save the settings
5. Exit UEFI menu
6. Restart your computer

2. At System Recovery Options (for Vista or seven systems) or Troubleshoot (for Windows 8 and eight .1), click prompt 

3. Type:

diskpart
