So I’m going over to the boot option using arrow key. And, there is the UEFI option. Again, we’re searching for UEFI legacy, or CSM Legacy is kind of something very similar. However, essentially the thing we’re going to do here is we’re switching between them. So in case, you’re identical to me, and you can see UEFI.

It would be best if you changed it to legacy or CSM. And, If you can see the Legacy or CSM there. You’re changing it to UEFI.

Now the best approach to do. This will vary in various Bios systems. but, with me, I highlight the option and then press Enter. and UEFI is enabled.

1st, Boot your PC via a Windows installation media accessible, which could be a USB flash drive, DVD, and CD. You need to press a key to reach the BIOS utility during the boot process.

Different PCs have a different Boot keys. However, there is consistently a Prompt this way:

2nd, Subsequent to entering BIOS effectively, you must have to set a boot order, specifically setting the Removable Device (bootable USB flash drive) or CD-ROM (bootable DVD or CD disc) as the primary boot device by utilizing keys like ↓,↑,  and pressing Enter. 

3rd, Once it has been successfully done, Save the changes and exit from the BIOS utility setting interface, and afterward, your PC will boot from the Windows installation media.

4th, At that point, you can see the Repair your computer option.

Next, you have to click on the Troubleshoot option, next select Advanced options, then open Command Prompt. 

Now the main thing, you have to type these commands. We mentioned below:

1st, Type the Command:

Diskpart

2nd, Type the command:

list disk

.it will show all disk lists.

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.

So it shows up much of the time. You’re not really ready to boot into Windows 10. To get around that, the initial step we need to really do is boot your PC to the Windows 10 installation USB or CD-ROM. that you may have used to at first install Windows 10. However, there’s additionally a media creation tool. You can download it from Windows’s official site.

You’ve finished setting those changes on BIOS (We mentioned previously) except before you click install now. We are going to instead click on Repair your computer. 

And afterward, this will open the Advanced Options menu. OK, so now that we’re under the Advanced Options menu, we need to choose the troubleshooting tile, which will reset your PC. Next, you need to select the command prompt on the top right here.

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.

Then type the command.

bootrec /fixmbr

To rewrite Windows MBR in the system partition of your hard disk. When it is over, we can see the message that the operation is completed successfully.

Utilizing this command isn’t in every case enough (for instance, if any virus is blocking the bootloader).

This is the reason you need to type the command:

bootrec /fixboot

To write another new Windows Master Boot account in the system partition. When it is finished, close the command prompt and try to boot from the disk.

Next, you need to enter:

bootrec /rebuildbcd

and then press Enter on your keyboard again. 

you need to type Y on your keyboard. when prompted to add the installation to finish it successfully.

Then type the command:

Exit

and type the next command:

bcdboot C:\Windows/s E:/f ALL

(Here С is your PCs drive letter; E – is the secret Hard drive segment or partition letter which you assigned on the disk part section) and waits for the cycle to finish.

After the cycle is finished, we can see a report saying that boot records have been created successfully.

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. 

So we need to switch it off. also, we’ll get directly into it. presently disclaimer clearly, do this at your own risk. if you don’t have any knowledge of what you’re doing, take it to an expert. But as a rule, it’s quite straightforward. so how about we do it? so since we’ve disconnected your PC. 

We will remove the sideboard. what’s more, examine now. before you do that however you will need a few pieces and bits of erases. you will need a brush. This will clean off a portion of the dust. and mess that you find.

Simply ensure it has sensibly solid bristles. In any case, it will not be effective. try not to utilize a brush that obviously is filthy or anything like that. you’ll need an eraser. ideally, one that is not also utilized as before but just a standard square pencil eraser will get the job done.

In case you don’t know which side comes off. find where your motherboard is. this present ones on the left side. This implies the right-hand panel comes on to get inside the PC.

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. 

I’m simply going to get my eraser. furthermore, put it down on the table here to squeeze it. so it doesn’t move around. Furthermore, I’m simply going to run this eraser all over. this gold contact simply puts a little bit of force on there. what’s more, this will easily handle all that filth sitting on these gold contacts.

It should agree with the motherboard when you set it back in sometime in the future. So remember that since, in such a case, you try to place it backward. Now reboot your pc, check the Reboot and select proper boot device error or Insert boot media in selected boot device error screen gone or not.

Solution #11, Reinstall Windows 10

In the event that this fixes your PC. You’ve recognized BIOS as the problem. if this doesn’t fix the “reboot and select proper boot device” error on your PC. Presently you need to proceed onward and analyze your hardware or your hard drive or your operating system in my Shop. I would then utilize a diagnostic program that I need to analyze the hard drive. if it’s healthy.

you don’t have that in a suit and it doesn’t have a built-in diagnostic program. so you will test for an operating system and the hard drive kind of at the same time. now if it’s not working. At that point, you have to try to reinstall Windows. 

Utilize the link to make a new reinstall Windows 10.

It’ll tell you the best way to download and install media from Microsoft free of cost. you can utilize that to reinstall windows new. if you install it and it turns out great. you’ve recognized that the operating system had the issue.
