You are doing a mega work session. You turn on your computer and an error is displayed: Restart the device and select the correct boot device. Wait a minute, what does that even mean? The computer worked just fine when you turned it off and now it has stopped working at all? If your system triggers the reboot and selects the correct device error, check the following fixes.
What's the mistake of restarting and choosing the correct boot device?
The "restarted and selected the correct startup device" error indicates that your computer cannot find the operating system.
During the startup process, your system BIOS / UEFI determines which hard disk your operating system is on. The operating system will then start and you will be taken to the Windows 10 login screen. This is an extremely simplified version of events, but you get the point.
If the BIOS does not recognize where the operating system is, it will not load.
Rebooting and choosing the correct boot device error have several possible causes:
Corrupted BIOS / UEFI installation
Damaged hard drive
These are not the only causes, but the root of a reboot and picking an appropriate device failure usually relates to one of these areas.
So how can you fix the reboot and choose the correct boot device error?
1. Check your connections
The first thing you need to do is check the connection between your hard drive (or SSD) and your motherboard in your computer. If your hard drive is not communicating properly with your motherboard or is completely disconnected, your operating system will not load.
Checking your computer case can be a bit overwhelming. You need to unscrew the case and then look for any cables that are not connected.
Clean your computer
While you have your computer's page open, take this opportunity to clean your computer. Cleaning your computer may not resolve the restart and select the correct boot device error. However, this can help protect against overheating and the problems that arise from it.
2. Wrong drive selected in BIOS / UEFI
If your hard drive is properly connected to the motherboard, then you'll need to try another fix. The next step is to check that your BIOS / UEFI recognizes your hard drive and your system boot order. From here, you can see if the hard drive is the first thing your computer looks for when you try to load the operating system, or if something has replaced it.
To check this, you need to enter the BIOS.
During the boot process, you must press the BIOS / UEFI access key. The specific key differs between computers, but commonly used keys include F2, F10, DEL, and ESC.
After the BIOS loads, find a menu or tab with the name boot or similar. Look for a menu named Boot device priority, Order of start options, or similar. The name varies between different motherboard manufacturers and the BIOS used, but the menu contents are the same.
In the device priority menu, you need to check two things. First, check if your hard drive is on the list. If it's there, that's a good sign. Second, the starting position must be checked. The hard drive with the operating system should be loaded first and should therefore be Start option 1 or the BIOS equivalent. Make sure that your operating system hard drive is in the first starting position.
Now save your BIOS settings and restart your system.
After restarting your system, your operating system should load properly.
3. Windows Startup Repair
If you're troubleshooting problems with the BIOS, or you didn't have a problem with the BIOS and boot order at first, there are two more solutions you can try.
Windows Startup Repair via advanced options
Use Windows’s built-in Startup Repair feature. Windows Startup Repair will automatically repair your startup problems – but only if it's running.
If Windows has problems booting, Startup Repair should start automatically. When that happens:
The Advanced startup options menu will open.
Go to Troubleshooting> Advanced Options> Startup Repair.
You will then need to enter your password. After that, the startup repair process begins.
The boot repair process may take a while, but it should fix your boot device error.
Fix the startup using the command prompt and Windows installation media
If the advanced startup options don't open automatically, you can still access them using your Windows 10 installation media. This is the Windows 10 USB drive or disc. If you don't have Windows 10 on a USB drive or disc, read our guide on creating Windows 10 installation media and move on to the next part of the tutorial.
Once you have Windows 10 installation media ready, you can force your system to load the installation process. From there, you can manually repair the startup process using bootrec.exe Tool.
Insert the Windows 10 installation media and turn on your computer.
Tap either F2, F10, F12, or ESC to bring up the system boot menu. These are some of the common buttons, but they vary from system to system.
The Install now The button is displayed. At this point, press Shift + F10 to open the command prompt.
Now you need to type the following commands in sequence, pressing Enter each time:
exe / fixmbr
bootrec.exe / fixboot
bootrec.exe / rebuildbcd
Once the process is complete, you can restart your computer, remove the Windows 10 installation media, and boot as normal.
Exporting and recreating the master boot record
If none of these fixes work, there is a third fix that you can try. Microsoft recommends exporting and recreating the BCD storage (the place where your startup data will be saved). You'll need to go to Command Prompt with your Windows 10 installation media following the steps in the previous section.
When you get to the command prompt, you need to type the following commands in sequence:
bcdedit / export c: bcdbackup
attrib bcd -s -h -r
ren c: boot bcd bcd.old
bootrec.exe / rebuildbcd
The export and restore process should repair your restart and select the boot device error.
4. Set the active partition
While using Command Prompt through Windows 10 installation media, there is another fix you can try. Windows DiskPart is a built-in system tool that you can use to manage your hard drives and hard drive partitions. In this case, you can make sure that your operating system's hard drive is active.
Re-enter Command Prompt with your Windows 10 installation media as detailed in the steps in the previous section. When the command prompt opens, do the following:
entrance Diskpart to enter the Diskpart tool.
Now enter List hard drive to view a list of the hard drives on the computer. You need to find out which drive contains your operating system. The drive letter for your operating system is usually C..
When you find the correct hard drive, enter it Select disk X. (where X is the corresponding plate number).
entrance List partition to list the partitions on the hard drive. You have to choose those system Partition that contains the boot loader (the bit of code used to start the operating system). In my case I would type Select partition 1.
Now enter active to mark the system partition as active.
Restart your system and the boot device error should no longer occur.
Troubleshoot the reboot and select the correct boot device error
The mistake of restarting and choosing the right boot device is frustrating. It comes up without warning and it can paralyze your computer and lock you out of your important files. You can use any of the fixes to restore your boot devices in the correct order and regain access to your computer.
How to Fix Master Boot Record in Windows 10
The master boot record (MBR) is a special type of boot sector that is located at the beginning of your system partition. The MBR informs the boot process of what will follow, e.g. B. Partition layouts …
