Dual Boot, Hard Disk Partition Issue

[khauam]

Hi, so I have a question actually, I saw the britec "How to Dual Boot Windows 7 and Windows 10" video and about the hard disk part where he would shrink his hard drive in half to install windows 10, if I did that with my SSD that has 240gb and split him into 120gb (C: with windows 7) and 120gb (D: with windows 10) would I be able to still install files in C: the one that has windows 7 operating system and use it in windows 10? and vice versa? or I would only have 120gb for all windows 10 files and not be able to touch in the other hard drive because it has another operating system?

a better example:
I downloaded a game while using windows 10 that is in D: but I wanna install it in C: that has windows 7
would I be able to play the game even if he is not in the ( D: ) windows 10 partition?

Yes... just create a new directory on the C: drive to point the download to.

After loading from the OS installed in D:\, you can choose to install your game in C:\. But you might couldn't play the game if you boot to the OS installed in C:\, except your game is a portable application.
