Right now I have a HDD with 100GB partition for my OS. I just received my SSD in the mail, and I am swapping Motherboard, CPU, and adding the SSD for my OS. I know how to download and install Windows 10 to the SSD and get it to boot, the thing is, how do I go about deleting the 100GB OS partition from my HDD? My HDD is 1TB and 100GB is currently used for my OS on the C: Drive, and I use the "A: Drive" as my storage for photos, important documents, and etc. I would like to remove the partition and not remove anything from my storage section in the A: drive. How do I go about doing this?
