Causes of “Reboot and Select Proper Boot Device Error”: There are few reasons why window users are facing this error on their system. There are two main causes which include physical issues and software problems.

  1. Physical issues: The meaning of physical issue consists of your boot disk not being connected appropriately to your PC’s hardware. If you have a boot disk that is already damaged or has failed or connected to a faulty cable, a damaged SATA slot, or a failed hard drive, you can face this issue.
  2. Software issues: When we talk about the software issues, it means you may face “Reboot and Select Proper Boot Device Error” if your computer system has an inactive boot partition, a dead or corrupted master boot record (MBR), a failed boot sequence in the BIOS, failed or absence of boot files. If your operating system is corrupted, it can also lead you to this error.

At this moment, we all are aware of all the possible causes, now it is time to look for the solutions. Here, in this article, we have come up with several solutions. Let’s take a look at the various causes that can fix this error:

Fix 1: Check the power cable connecting your hard drive disk

If you want to use your system without any interference, you need to make sure that the hard disk drive that stores the operating system, should be connected to your motherboard with a power cable. In case the power cable is broken, frayed, or not connected properly, likely, the hard drive is not being detected by the PC. To fix this, you need to do is:

First of all, you need to power off your computer and open it up (Restart process).

Now, you have to navigate the power cable running from the hard drive disk to the motherboard. After that, you need to find out if it is physically damaged and connected properly or not.

At this point, we are hoping you have checked it. However, in case you found out that it is properly connected but you are still getting the same error, then you are required to remove it from your system (PC) and test it on another one.

In case, the “Reboot and Select a Proper Boot Device Error” occurs on the test computer too, then the last option is to replace the power cable with a new one.

However, if everything goes well with the test computer (meaning no error on the test computer), then re-attach your power cable appropriately and move onto the next steps mentioned down below.

Fix 2: Clean your Random Access Memory (RAM)

Cleaning the RAM (Random Access Memory) is very important for the smooth running of your computer. If your RAM has not been cleaned or taken out since you got your PC, it could be the reason for the error.

To clean the RAM, you need to power off your system and pull off your computer’s sideboard by removing the screws from the tower or bottom of the PC, laptop and find your RAM. 

Now you have to open the clamps that keep your RAM in place and then carefully remove them from their positions.

After that, you need to clear any dust present on the RAM with a soft cloth and reposition them back into their spaces.

Now you need to clamp them in place, close your system (PC, laptop). At last, you need to restart the system to check if the error is solved or not.

Fix 3: Check if boot drive is detected in BIOS

In case the boot drive is not detected in your system’s BIOS, you need to follow the steps mentioned down below:

First of all, you need to restart your system and after that just press the post-screen designated key which will lead you into your computer’s BIOS.

Here, you will find a list of all devices that are detected by your BIOS, on the main screen of your BIOS. The list will include fans, hard disk drives, and any other hardware that you have connected, for example, a DVD and CD drive.

You need to turn off your computer, in case your hard disk drive is not listed, and then turn it on- basically a restart.

Now, when the computer is open, you need to connect your hard disk drive to another SATA slot or you can utilize another SATA cable to connect the hard disk drive to another SATA slot in your motherboard.

Here, you need to restart your BIOS to check if the hard disk drive is detected or not. If yes, you should realize that it was either the cable causing the error or the SATA port on your motherboard which should be blamed.

However, in case it is not detected, the boot disk may be bad, corrupted, failed, damaged, or dead. You need to change that to get rid of the error.

Fix 4: Check boot order in BIOS

There are times when the mucked-up boot sequence is the real culprit. You know what, the muck boot sequence can get mucked up and lead you to experience the “reboot and select proper boot device” error.

To find out the boot order in your BIOS, you need to boot the computer up and then enter the BIOS with the post-screen key.

In the BIOS, you need to go to the “Startup” or “Boot” tab or screen. Here the boot order will show up on the main screen on the news BIOS systems.

Note- In case you are not able to find the boot sequence, you can try the advanced BIOS features to find it there.

At the moment you find the boot sequence list, now you should ensure that your boot disk is the first device listed.

However, in case it is not listed in the first position, however, if you find it in the list, you need to move it to the first position.

To do that, you simply need to drag and drop to change the boot order in the newer BIOS systems. You can use your arrow keys in the older BIOS systems.

When your boot drive is in the first position, you need to save the changes and restart your computer to check whether the error is solved or not.

Fix 5: Disable, enable legacy boot

There are few cases when the basic input, output system (BIOS) may come with a feature named a legacy boot, which can lead you to experience this annoying error named the “reboot and select the proper boot device”. If you want to fix it, you are required to disable it or enable it. Here how you can do it:

First of all, you need to reboot your system and then go to the BIOS.

At the moment, you found it, you need to enable it if it is disabled. If it is disabled, then enable it.

Here, you have to save the changes and exit the BIOS.

At last, you just need to restart your computer to check whether the error is solved or not.

Fix 6: Set BIOS to defaults

To be honest, this method is a bit of a long shot, there are times when you do not have your BIOS set to its default values which can be the reason to cause instability. Further, this instability can definitely lead you to face “reboot and select proper boot device error”.

In order to do that, first of all, you need to restart your computer system and then load it into your BIOS.
