Solutions to Fix Reboot and Select Proper Boot Device in Windows:
The solutions mentioned will work for all Windows versions including Windows 10. Thus, you can use them to solve reboot and select proper boot device Windows 10 as well.
Solution 1: Check the Power Cable Connected to the HDD
Make sure that the power cable is properly connected to the HDD. Otherwise, your computer will fail to detect the HDD and cause this error. Even if the problem occurs after checking the connection, then the power cable is most likely to be faulty. So, test the situation by using another power cable.
Similarly, you can test the same power cable on a different computer. So, if the power cable seems to be faulty, then replace it with a new one. Whereas, repair your computer if the problem lies somewhere else.
Solution 2: Clean RAM
It is not an easy task to clean the RAM manually. Still, access the RAM on your computer and make it clean with a soft cloth. If the error continues, move to the next solution.
Solution 3: Check the BIOS Settings
BIOS is one software incorporated inside the motherboard of computers. It is entirely responsible for running the Operating System and connecting all components of your computer.
If the BIOS settings are not correct, the motherboard won’t detect the hard drive installed on your computer. Thus, you will face many difficulties including the reboot issue. So, check the BIOS settings as we have discussed below.
- Open the Settings app and navigate to the ‘Update and security’ section.
- Click on the ‘Recovery’ in the ‘Update and Security’ section and select the ‘Advanced’ option.
- Click on the ‘Restart Now’ button to prompt your PC to reboot.
- Instead of the login page, you will find a ‘Choose an option’ screen.
- Click ‘Troubleshoot’ to access the ‘Advanced Options’ window.
- Then, select ‘UEFI Firmware Settings’ and click the ‘Restart’ button when prompted.
- Your computer will restart once more time and open the BIOS settings page.
- The BIOS setting page might look different depending upon the manufacturer of your computer.
- So, head over to the dashboard to check whether the motherboard detects the hard drive or not.
- If the motherboard can’t recognize the hard drive, then check the connected cables.
- Whereas, if the motherboard detects the hard drive, then check the boot order.
- Now, go to the ‘Boot’ tab and find the list of programs arranged therein.
- Rearrange the order and place the hard drive in the first place. ‘
- Thus, from now onwards, the hard drive will load first and act as the foremost boot device.
Solution 4: Disable or Enable Legacy Boot
This solution can be applied to UEFI computers only. So, if your computer BIOS has been replaced by UEFI, then enable or disable the Legacy Boot features as discussed under.
- First, go to the Start menu and click the arrow next to the Power button.
- Select the ‘Restart’ option and enter your computer’s UEFI settings menu as the computer restarts.
- In case the Legacy Boot option is active, then disable it and click on the ‘Save’ button.
- Then, restart the system and check whether it boots normally or not.
Note: Refer to the user manual as the process of entering the UEFI settings menu can differ according to the computer model.
Hopefully, the aforesaid solutions will help you to find a way from getting rid of the error in question. However, if the error continues to appear, then update the drivers associated with the system reboot. If nothing happens, then uninstall and reinstall the Windows Operating System to fix the issue. Finally, replace the CMOS battery if the existing one is no longer in good condition.
