Windows 7 on second hard drive

[KawaiiDoge]

Hey guys, I have an SSD in my pc, as well as a hard drive, the SSD is my main OS drive with windows 10, and my 500gb hdd, is for games and such, and has windows 7 from when I was using it as my main os drive, is it safe to now delete it? I will not be going back to Windows 7, so I'm okay with deleting it if it won't affect anything else.

Welcome to the community, KawaiiDoge!

I'd advise you to install Windows 10 onto the SSD and make sure you have the HDD unplugged during the installation. Otherwise, it's highly likely to encounter an OS confusion, which would require you to re-install everything from scratch again.
Once Windows 10 is up and running onto the SSD, you can plug back the Windows 7 HDD and reformat it through Disk Management. This will erase everything you have on the hard drive, so make sure you have backed up any important data beforehand.
Once the drive is reformatted, you shouldn't have any issues using it as a secondary storage for your data.

Best of luck! Keep me posted if you have any more questions!
