Switching on the computer and getting a ‘Reboot and Select Proper Boot Device’ error screen, which prevents you from booting up your operating system or doing anything at all, has to be one of the most aggravating things. Even if you repeatedly reboot the computer, the issue persists, frustrating you.
Many users of Windows 10, 8, or 7 get a black screen with an error message that says “reboot and select suitable boot device.” This error message could be caused by a failing or failed hard disc, corrupted system files, or an erroneous PC startup order.
Let’s take a closer look at what might be causing this error number and how to repair it.
What Is Reboot And Choose Proper Boot Device Error?
This problem indicates that the BIOS (basic input/output system) on your computer is unable to locate the boot drive that contains your operating system.
When the device prompts you to restart it, enter the BIOS (UEFI) and select the boot device that contains your operating system, then get the PC to boot up from there.

What Causes This Error?
There could be a problem with the software. A defective or broken master boot record (MBR), an inactive boot partition, a flawed BIOS boot sequence, lost or corrupted boot data, or a corrupted operating system are all possible causes.
A failed or damaged boot disc, a boot disc that isn’t correctly linked to the PC hardware, a bad connection, a dead hard drive, or a damaged SATA slot are all examples of physical computer problems.
To boot into the BIOS system, you must restart the computer and keep pressing a key. The key to the press might be F2, F8, F10, F12, ESC, or DEL, and it should be displayed on the post screen.
If not, it should be listed in the motherboard handbook that came with your PC. Continue pressing the key until the PC enters the BIOS system, then attempt the remedies below. Also, read How To Fix Twitch Error 2000.

Your PC will not be able to recognize the hard drive if the connection is not correctly attached, frayed, or broken.
