New Computer Reboot & Select Proper Boot Device Fix

In this article, I will discuss how to fix the “Reboot and Select proper Boot device” error on a new computer.

Common Causes of Boot Device Errors

Boot device errors can be frustrating, but they are often caused by common issues that can be easily resolved. One of the most common causes is a corrupted boot sector or master boot record. This can happen due to a sudden power outage, improper shutdown, or malware infection.

Another common cause of boot device errors is a misconfigured BIOS settings. Make sure to check your BIOS settings and ensure that the correct boot device is selected.

Hardware issues, such as a faulty hard disk drive or solid-state drive, can also lead to boot device errors. It is important to check the connections and health of your storage devices regularly.

Software issues, such as corrupt device drivers or an outdated operating system, can also cause boot device errors. Make sure to update your drivers and operating system to the latest version.

If you suspect that malware may be the cause of your boot device errors, run a full system scan with your antivirus software. It is important to keep your system clean and protected from potential threats.

Checking Boot Drive Detection and Order in BIOS

Step Instructions
1 Access your computer’s BIOS by pressing a specific key during startup (often F2, F10, or Del).
2 Navigate to the “Boot” or “Boot Order” section in the BIOS menu.
3 Check if your boot drive (usually your main hard drive or SSD) is detected by the BIOS. If not, check the connections and power supply to the drive.
4 Ensure that the boot drive is set as the first boot device in the boot order list. You may need to use the arrow keys to move it to the top of the list.
5 Save your changes and exit the BIOS. Your computer should now boot up from the correct drive.

Setting Correct Active Partition and Rebuilding MBR

To set the correct active partition and rebuild the Master Boot Record (MBR) on your new computer, you will need to access the Command Prompt. Press the Windows key + R, then type “cmd” and hit Enter.

Type “diskpart” in the Command Prompt and hit Enter to open the disk partition tool.

Next, type “list disk” to display all the disks connected to your computer.

Identify the disk that contains the Windows operating system and note its number.

Type “select disk X” (replace X with the disk number) and hit Enter.

Then, type “list partition” to display all the partitions on the selected disk.

Identify the partition that should be set as active and note its number.

Type “select partition Y” (replace Y with the partition number) and hit Enter.

Finally, type “active” to set the selected partition as active.

Once you have set the correct active partition, you can rebuild the MBR by using the “bootrec” command in the Command Prompt. This process will ensure that your computer boots up correctly and resolves any boot device selection issues you may have been experiencing.

After running these commands, restart your computer and see if the issue has been resolved. If not, you may need to consider other options such as running a system restore or reinstalling Windows.
