Windows startup repair is one of the tools in System Recovery menu used when the system does not boot normally. It is designed to fix damaged or missing system files that are necessary for booting the system normally. You can access this tool on your system or on the Windows installation disc.
Method 1: Access startup repair from recovery menu
If your PC doesn’t start, you can access Windows startup repair tool by following the steps below.
- Restart your system and choose a boot option. In Windows 10 and Windows 8, keep pressing F11 until the ‘Choose an Option’ screen appears.
- Next click on Troubleshoot > Advanced Options
- From the advanced options menu, select Startup repair
Now the tool scans your drive and attempts to fix errors, so your computer can boot normally. If the repair is successful, you will receive a success message. If not, you may have to run the tool again depending on the error.
If the repair is still not successful, Startup repair may suggest that you perform a system restore. You can proceed if you prefer, if not click Cancel to stop the process.
If you want more details about the process undertaken by Start-up repair, click on ‘View diagnostic and repair details’.
However, sometimes you may not be allowed to access Startup repair from the boot. In such cases, you can use the Windows installation CD/DVD to access startup repair. This is explained in detail in the next section.
Method 2: From Windows installation media
You can access startup repair from the Windows installation media as well. If you don’t have it handy, Microsoft allows you to download and copy it to a USB or DVD.
- Insert the installation media into the system that cannot boot normally
- You will receive a message ‘Press any key to boot from DVD’. Watch out for that and press any key appropriately.
- In Windows 10 and 8, click on Repair your computer in the bottom left corner
- Then click on Troubleshoot > Startup repair
Now Windows will run Startup Repair and fix problems issues associated with system files that help the computer boot and work normally.
If this does not work, you will have to reinstall Windows entirely and check if your system can boot. Of course, if there are physical issues with hardware, this may not be helpful.
Using a Windows installation media start-up repair, you can also fix errors such as ‘Bootmgr is missing’. However, if you have lost data due to these errors or while performing some of these procedures and there is no backup available, you can use data recovery tools such as Yodot data recovery software. It is a comprehensive hard drive recovery software that can be used to recover data and partitions. For detailed steps on recovering data refer ‘Bootmgr is missing’ guide.
