Other factors such as low disk storage, issues with the ISO file, or problems with the disk can also trigger this error.
1. Run CHKDSK
It is recommended to run CHKDSK before trying anything else. This command scans the disk drive for errors and fixes them. Running this scan will detect and fix any disk errors.
2. Check Disk Storage
Check your disk storage. If there is not enough space available on your PC, this can lead to issues and cause this problem. The minimum storage required to upgrade to Windows 11 is 64 GB. If it’s not enough, you can try disk cleanup, which will remove all unnecessary files on the drive like temporary files, system update files, and other cached files. This can help free up storage space for Windows to upgrade, potentially resolving the issue.
3. Extend EFI Partition
Insufficient storage in the EFI partition can also cause this problem, as the EFI partition contains the boot files that load when the PC is powered on. You can extend the EFI partition using the Command Prompt in Advanced Startup settings. Note: Ensure to backup your data before proceeding with this method. Although this step shouldn’t cause any problems, things can go wrong sometime with Windows and you could end up losing some important data that you may have in your storage drive.
4. Clean Install Windows
If none of the solutions work, you can perform a clean install of Windows, which might help solve the issue. Clean installing Windows will delete all previously installed files and download a fresh version of Windows. You can check our article on how to clean install Windows here.
