Tip: This whole process can just help fix some predefined boot issues, Such as system files getting lost, but it can’t fix the problem 100%.But again, if it would be a solution step of Reboot and select proper boot device error.

Solution #9, Check The System Boot Configuration Data

Look over how to resolve issues ideally. You may have explicitly the error code “0XC000F” in Windows 10. 

Such as, when attempting to start  the PC, you got errors, for example, “BOOTMGR is missing,” 

 “No bootable device found” “reboot and select proper boot device” and so on.

In this way, the primary technique to fix the bootloader will work with all versions of Windows: 7, 8, and 10 (in my situation, it is Windows 10).

You have to wait for a moment, and it will open the command prompt.

You need to choose the account that is an administrator on your PC. My administrator account turns out to be named computer, and I’m going to enter my password. Alright.

This is the reason you need to type the command:

bootrec /fixboot

Solution #10, Clean Your RAM

This is an excessively common issue that I see on PCs. particularly those that exist in a kind of damp and kind of dusty climate. This is something I see across all various kinds of PCs, even a few laptops.  and, I wouldn’t go over the thing that is engaged with cleaning the inside memory. also, it’s called RAM. 

And, guaranteeing that those memory sticks are clean. what’s more, their slots are also clean and situated appropriately. so this is a typical common reason why many PCs won’t boot up or why they’ll freeze. I’ll have some graphical glitching. it might produce the reboot and select proper boot device problem.

you realize this can be caused by all kinds of things. PCs are complicated machines. but, this is presumably the most well-known reason why PCs make trouble.

Not very confused. so you can see the modules here (See the Picture). These are what we call RAM or system memory. and, this is the thing that I find is presumably the most well-known reason for system issues concerning boot up or freezing or general crashing. 

so the thing we will do is, we will take these out and we will give them somewhat of a clean. 

So to pull off the RAM module you should simply put your finger or your thumb on these little clasps. also, do what needs to be done on the two ends and they ought to turn out to be free and they would now be able to come out.

you’ve taken out your RAM. we’re going to examine these gold pins down the side of the RAM. also, simply check whether you see any residue or signs of filth sitting on these pins. That tends to be one of the tell-tale signs of RAM issues in your PC.
