If you’re faced with this issue, you can try our recommended solutions below in no particular order and see if that helps to resolve the issue. Let’s take a look at the description of the process involved concerning each of the listed solutions.

Not enough space to Reset PC

1] Run Disk Cleanup

As indicated in the error message, to free up some disk space, you need to run Disk Cleanup. Make sure you remove all unwanted files including Windows Update Delivery Optimization Files or old Windows version files. Disk Cleanup is a maintenance utility that was developed by Microsoft for its Windows operating system. The utility scans your computer’s hard drive for files that you no longer need such as temporary files, cached webpages, and rejected items that end up in your system’s Recycle Bin. Unless you remove those files, they add up over time and begin taking a lot of space on your computer. The utility displays the identified files and the amount of storage space that each of them uses within your hard drive. You decide which items to delete by the importance that you place on the files and the amount of hard drive space that you’ll be able to recover. If after the operation and you’re still receiving the Additional free space is needed on the drive where Windows is installed error message, you can try the next solution.

2] Run CHKDSK

This solution requires you to run CHKDSK. CHKDSK (pronounced check disk) is a command that displays a status report for a volume, such as a disk, and can correct any errors found in that volume. To use CHKDSK, computers must have the Autochk.exe file already on their system. Admins have options for what switches to run with CHKDSK.

For example, using /f tells CHKDSK to fix any errors it finds.Using /r tells CHKDSK to look for and recover any readable information in a disk’s bad sectors.

3] Clean install Windows

At this point, if the issue persists, it’s most likely due to some kind of system corruption that cannot be resolved conventionally. In this case, you can back up your files/data and then clean install Windows 11/10 and see if that helps to resolve the issue. Hope this helps!
