We couldn't create a new partition or locate an existing one

One possible solution is to manually create a new partition from Windows 11 installation screen.

You see the error "We couldn’t create a new partition or locate an existing one" and you're already on the "Where do you want to install Windows?" screen with partition options listed.

Step 1: Delete All Existing Partitions (Data Loss)

Select each partition one by one (e.g., "Drive 0 Partition 1", "Drive 0 Partition 2", etc.). Click Delete and confirm until you only see “Unallocated Space” on the drive.

Step 2:  Create a New Partition

Select the Unallocated Space (usually “Drive 0 Unallocated Space”).

Click New → then click Apply (accept the default size unless you have a specific reason to adjust it).

Windows will automatically create:

Primary partition (where Windows will install).

System Reserved, MSR, or Recovery partitions as needed.

Step 3: Select Primary Partition

Click the newly created Primary partition (the one with the largest size or labeled as "Primary").

Click Next to continue the Windows 11 installation.

If this still doesn't work, click Refresh after deleting or creating partitions, or restart the PC and try the same steps again
