Hello, I currently have Windows 10 installed on C drive, and I have a D drive for downloads pictures and stuff, so my question is, if i install Windows 7 to the D drive will it delete my files? ( custom install)
It won't necessarily delete your files if you properly partition it beforehand, but that makes installation a bit more difficult. Could you move the pictures and other things to another PC or storage while you do the installation instead?
I would if I could, but my old hdd died and now this one is like 600 gb used, and the D drive uses like 400ish gb so I dont have where to place it. The critical files take maybe a 100gb or something and a backed up hdd, i tried to install just now but i though no it could break and now my taskbar is black and start menu wont open. A Windows.old got created in C drive too though. (Could it be installing to C drive?)
So there is only one drive, but it already has multiple partitions? I didn't quite understand the drive setup.
It is quite possible that you accidentally tried to install to the C drive. Make sure you select the right partition on the installer, or you could easily lose valuable data. I would consider manually adding a partition before trying to do the install, and then selecting that partition during the installation.
There are problems installing win 7 after win 10 on same drive. Main one being win 10 won't boot as the win 7 boot loader will overwrite it.
Is your bios set to legacy boot? If its set to UEFI and HDD is formatted as GPT, then win 7 won't boot anyway.
Ideal situation is use two hdd and install them in the win 7/win 10 order, not opposite.
