What is Startup Repair & What does it do on your computer?

Startup Repair is a tool designed to fix problems like missing or damaged system files used to load the Windows operating system. It can’t detect or fix hardware failures, nor does it help against virus attacks and the damage they do. Instead, it scans your computer or device for system issues (corrupt system files, invalid boot files) and then tries to fix the problem.

Obviously, this tool is safe, as it’s made by Microsoft itself, and it comes in handy when Windows fails to boot correctly.

How to launch Startup Repair

Obviously, your computer or laptop can’t boot Windows properly, which is why you’re trying to run Startup Repair. So, you can’t rely on your operating system to launch it. But, in order to use this tool, you can and should boot your Windows computer from a recovery drive, a System Repair disc, or a Windows installation drive.

Either one will work, and you can create any of them on a working Windows 10 or Windows 11 computer. If you don’t know how to do that, here are some tutorials that will guide you through the required steps:

Before we go any further, you should know that the steps you’ll have to follow and the options you’ll get are the same in both operating systems - Windows 10 and Windows 11 - so, to keep things simple, we’ll only use screenshots taken in Windows 11.

Once you have a recovery drive, a System Repair disc, or a Windows installation drive ready, boot from it. To do that, plug it in and start your computer or device. Immediately after your PC starts, press the boot device selection key from your keyboard. It’s usually the F12, F11, or the Escape key, but it could also be another one, depending on the manufacturer of your computer’s mainboard.

Doing that will make your computer display a boot priority selection menu. Use the arrow keys on your keyboard to select the USB recovery drive or the System Repair disc. Then, press Enter.

If Startup Repair manages to repair your problems, you are informed, and you can restart your Windows computer or device and use it normally again.

On the other hand, if it can’t repair the problems, Startup Repair will tell you about it, and you’ll have the option to access the Advanced options screen again, where you can find other troubleshooting tools. Or... you can simply Shut down your computer.

In case you’re wondering about “How long should a Startup Repair take?” we can tell you that it should all be over in a few minutes on a modern computer with a solid-state drive. However, on a slow PC that still uses a hard-disk drive and a lot of boot issues, the whole process will take longer than that.

TIP: If nothing seems to work to make your computer boot normally, your MBR or EFI Bootloader might be broken. In that case, you might want to try troubleshooting them using the bcdboot or bootrec tools. You’ll find instructions here: Repair the EFI Bootloader or the MBR (Master Boot Record) for Windows.
