Reinstall Windows 11

I'm Greg, 10 years awarded Windows MVP, specializing in Installation, Performance, Troubleshooting and Activation, here to help you.

The definition of a "Clean" install is to wipe the drive clean. You don't need any of those partitions, as long as your data is properly backed up. The WinRE tools will be replaced by a Windows 11 Recovery partition that contains them. The Image partition which contains the Dell factory image of your old OS will be useless wasted space. So what I'd do is delete them all one-by-one, select the resulting Unallocated Space and then click Next which will automate creating and formatting the needed system partitions and begin the install.

Workable SolutionsStep-by-step Troubleshooting
