Should I Delete All Partitions When Installing Windows 10?
Contents

You’ll need to delete the primary partition and the system partition. To ensure a 100% clean install, it’s better to fully delete these instead of just formatting them. After deleting both partitions, you should be left with some unallocated space.

Is deleting partitions okay?

Yes, you can delete those partitions and it won’t affect anything on your current operating system. If there is nothing on the entire disk that is needed, I like HDDGURU. It’s a quick and simple program that does a low level format. After, just format it to NTFS in disk manager.

Will reinstalling Windows remove partitions?

It depends. While you literally reinstall Windows 8 (from usb drive or dvd), you will redirect to disk selection. In this section you will choose partition where windows 8 will be installed. In this section you can delete or format partition, or left the way it is.
