I asked you for a screenshot of Disk Management - Post a Screen Capture Image
which is required before we can safely advise you how to delete the other OS.
The correct way to delete an OS is to delete its partition in Disk Mgmt or using a boot disk.
The partition is active, Greg. But, I will post a screenshot of disk management.
Disk Management
Yep right click D partition and click on Format leave as default ntfs and agree that all items will be erased
At that point you can leave it as a D partition with nothing on it or right click it again and click on Delete
That will make it Unallocated space just like the 15.10gb in front of C partition,
After that it's up to you if you want to reclaim all of unallocated space now or later ?
You can reclaim the portion to the right of C by using Windows Disk Management.
You would need a third party tool such as Partition Wizard to reclaim the portion to the left of C.
Your C partition is only 20 percent occupied, so there's no over-riding reason to reclaim the space. You can just ignore it for now and reclaim it next month, next year, or never--whenever you need the space.
Here's one I've used to reclaim to the left of C or to the right of C partition
To the right you can easily use disk management but the 15gb to the left you'll need mini tool
Do you want to add space to system c drive partition or resize system partition? The partition magic MiniTool Partition Wizard is a good choice.
I believe Greg has a better video of using mini tool that I'm not finding at the moment
If I find it I'll post it unless Greg returns with it himself :)
For the portion to the right of C, after you have deleted D.
Go to Disk Management.
Click on C partition.
go to Action menu.
choose All tasks.
choose Extend Volume
