Unlike any previous Windows operating system, Windows 10 is not a specific OS. It more a service than operating system (it includes a series of personal computer operating systems released by Microsoft). Can’t boot into Windows 10 is horrible and desperate; because of that, I’d like to talk about the Windows 10 boot failure error and introduce the useful repair tools and methods.

Till March 2019, there are more than 800 million Windows 10 users. So any problem on Windows 10 would have huge repercussions. One of the most terrible problems users could meet on Windows 10 is the computer boot failure. Once you find your Windows 10 won’t boot, no programs on the computer could be used and no data saved on the disk could be accessed. What a hopeless thing!

But luckily, Windows 10 boot failure can be fixed in most cases. You can use the Windows installation disc, built-in Windows programs, and even third-party software (from MiniTool Solution and other renowned company) to fix the problem so as to boot into Windows 10 successfully again.

Therefore, my focus on will be put on introducing Windows 10 boot repair tool and the corresponding steps to repair Windows 10.

Causes of Windows 10 Boot Failure

Before talking about Windows 10 repair, I’d like to show you the common reasons for causing a computer not to boot (the causes of disk boot failure Windows 10). The disk boot failure is a serious problem that will make your Windows 10 fail to load correctly. You will see a black screen or blue screen when you can't boot Windows 10 and the error message & error code will be displayed in most cases.

There are 8 main factors responsible for Windows 10 startup problems.

#Factor 1: the Boot Disk Is Not Connected Properly

Your computer will not recognize a hard disk if it is not plugged in correctly or if the connection is loose.

Fix: you need to shut down your computer and remove all power supply; then, check the connection between your boot disk and the computer.

#Factor 2: the New Disk Is Not Configured Correctly

If you have brought a new hard drive to replace the old boot disk but didn’t configure it in the right way, you also can’t boot into Windows 10 successfully.

Fix: you’d better power off your computer -> insert the system installation disc -> set up the new hard disk properly.

#Factor 3: the Boot Sequence in BIOS Is Not Correct

As you know, the function of BIOS (Basic Input/Output System, also known as System BIOS, ROM BIOS or PC BIOS) is to look for the bootable hard drive on the basis of the configured boot device order when you start a computer. Therefore, it’s the BIOS boot sequence is not correct, your Windows 10 will not boot.


Fix: enter BIOS window while starting up your PC in order to change the boot order, moving the correct boot disk to the first place.

Note: A corrupted BIOS on Windows 10 could also lead to the boot failure. In that case, you need to repair/fix the BIOS so as to boot into Windows 10 system successfully.

#Factor 4: the System Files Are Corrupted

System files play a significant role in booting an operating system (OS). If the necessary system files are corrupted/damaged, of course your Windows 10 will not boot up.

Fix: if you don’t have any backup of the system files, you’ll have no choice but to reinstall your Windows 10 OS.

#Factor 5: the Boot Partition Or Disk Is Damaged

Assume that the bootable hard disk or Boot Partition is damaged, your Windows won’t start. Once a partition/disk is damaged, all data saved on it (including boot files) will be affected, so Windows 10 fails to boot.

#Factor 6: Partition Table Is Invalid

Located on the hard disk, a partition table is a 64-byte data structure that contains information about the disks and partitions layout. In some cases, Windows 10 won’t boot because the partition table becomes invalid.

Fix: you should find out the possible causes for invalid partition table error and then perform corresponding solutions.

#Factor 7: the Boot Sector Is Damaged

The Boot Sector is actually a physical sector on your hard drive; it stores necessary information that should be used to complete the OS boot process. Therefore, Windows 10 repair is needed if the boot sector is corrupted due to virus attack or other reasons.

Fix: you need to fix/rebuild the Master Boot Record (mbr) and remove virus to fix the corrupted boot sector effectively.

#Factor 8: There Is Software Conflict with System Settings

Sometimes, your system will run as usual after you have installed new software on the computer. However, when you restart the PC the next time, it won’t boot up. The possible reason for causing this is that the new software is conflicted with your current OS.

Fix: you need to boot into Windows recovery to uninstall the software or reinstall the operating system (which will definitely lead to data loss).
