Answer 1

Boot into Windows.

Open the Disk Management.

Identify the partitions associated with the Linux installation.

Right-click on each of the Linux partitions and select "Delete Volume"

Once you've deleted the Linux partitions, you should have unallocated space on your disk. Right-click on the Windows partition and select "Extend Volume" to expand the Windows partition to use the newly available space.

Run a disk cleanup in Windows to remove any leftover files or folders related to the Linux installation.
