For a computer to run a boot, everything from the system to the boot device should be ready to function without any hiccups fro corrupted or damaged files. However, the boot device not found error can sometimes occur, leaving one with a headache, trying to troubleshoot this problem. There are various reasons that cause this error. It could be due to a corrupted or damaged bootable disk, damaged boot sectors or MBR on the boot disk, BIOS disorganization, or hard disk connection problem. Malware can also damage boot sectors or the entire bootable disk.
The boot device not found error is a common Windows problem with 4 error prompt scenarios:
When you receive these errors, the PC will fail to boot, due to undetectable bootable disk or boot sectors. The hard disk cannot support the system boot process because the BIOS failed to make the connection with the boot device. In order to start your computer normally, you will need to perform one of these actions:
a. Turn off your PC.
b. Remove any docking station and unplug AC adapter. Check and unplug any other external devices plugged in the PC.
c. Long press Power button to drain the remaining charge for 15 seconds.
d. On the Startup menu, navigate to Start Windows normally using your arrow keys.
e. Press Enter.
a. Turn on your PC and immediately press the F10 key a few times to enter BIOS menu.
b. Press F9 to restore previous BIOS default settings on the setup menu.
c. Once the settings load, press F10.
d. Choose YES and then press the Enter key to save the changes.
e. Follow the wizard and restart accordingly.
a. Long press the Power button to switch of the PC.
b. Unplug the power socket from the outlet.

Since this error is caused by a number of reasons, identifying the root problem might not be an easy task. Here are three of the usual culprits that cause this specific error.
Boot device not found error is usually caused by a bad sector. Boot device (aka the hard drive) is made up of partitions or sectors. If any one of these are damaged either by corruption or deletion, the BIOS will fail to access the Random Access Memory (RAM), which in turn causes failure to boot. This causes the hard drive to be unable to read and write requests made at boot.
Although the hard drive performs error checks even when unprompted, there are certain cases that prevent the hard drive from responding to commands. One common factor is a faulty or damaged hardware.
The MBR or Master Boot Record is an important component of the booting process. This section of the hard drive has executable files used to load the OS into the RAM. Some factors that damage this part of the boot device is usually caused by a virus attack, overwrite of the MBR or total disk failure. An MBR damage entails rebuilding it entirely.
Seek an IT professional who can rebuild the MBR for you, so that recovery is done fast and no further damage is made.
Physical damage to essential sections of your PC causes the whole system to fail. The computer has a lot of parts, and most of the tiny mechanisms work in congruence to each other. The hard drive is a fragile part, and boot failure may be caused by damages in the motor failure, platter scratches, PCB damage, or head crash. Maintaining your boot device's health by regular integrity checks is recommended. If any damage is already made, you can contact an expert instead of the DIY approach to make sure that no further damage is done to the PC.
With the right tools and expertise, the error Boot device not found can be solved. There is no need to worry because these methods are the most common solutions to the specified error. However, you can also seek an IT expert's help if you want the problem to be solved efficiently. The DIY approach poses a lot of potential threats. Your PC is a delicate contraption that requires.
