How to Fix “Reboot and Select Proper Boot Device” Error in Windows

When you see the error message “Reboot and select proper boot device” on the screen, it clearly shows that there is an error in the BIOS. When the BIOS of your system has any issue due to any reason, it cannot detect the system’s drive. It even cannot detect any bootable device in the system. So, it shows this error message. It is not specific to one operating system.

It can occur in Windows 7, 8 or 10 or may be any other version of operating system. Let me explain this error a bit. The operating system exists on the Hard Drive, and a chip is installed on the motherboard of your PC is known as “BIOS Chip.”

When you boot the system, the BIOS Chip starts the operating system and runs it with the help of Boot Volume. When the BIOS cannot recognize the OS drive, it shows a message “Reboot and select proper boot device.”

If you are connecting a bootable USB flash drive and your system shows this error, it means your flash drive is not functioning well. That’s why it is showing the error. So, you need to disconnect it from the system. Wait for a few minutes and then reconnect it to another port.

If you have bought a new system and you encounter this error on that, it means there may be no OS exists on it. You need to install an operating system on it. Sometimes, you see face this problem when you install an SSD or new Hard Drive to your system. There may be an error in the new Hard drive you are trying to install.

If you see this error frequently, it means you need to use the following fixes to get rid of this grim issue. If you encounter this problem, no worries.

Precautions to Follow Before Going Ahead

If you have connected any USB flash drive with the system, just disconnect it. Make sure the DVD/CD-ROM is empty, and it does not contain any CD or DVD. Moreover, you do not have any floppy disk in its drive. When you connect the external drive with the system, these devices can show the error. So, before going ahead, please remove all of the above-discussed drives from the system.

Well, guys! Without much ado, let’s move towards the guide to see what techniques I have brought for you guys to get you out of this grim BIOS error.
