Can macrium reflect free do just the OS system files versus the personal data files?
I have a separate 3tb drive I use for personal files and video recordings. The 1 TB drive has win7 on there.
Mostly that 1TB goes to waste, only used for the OS.
It would be nice to just back up a bootable system leaving out the extra personal files. Anyhow that drive has about 40gb, what size would an image be?
I am on win10 on its own drive, win7 has its own drive too. Can the image be made of the non running win7 drive and written to the 3tb drive? As in running macrium from win10, I suppose so.
If the non-running Windows 7 drive is on, then yes, Macrium can make an image of it. However, Macrium Reflect Free is somewhat limited compared to the paid version. I don't think it could back up just the OS part of the drive; but I may be wrong about that.
It sounds like you have three drives: one for data, one for Windows 7, and one for Windows 10. If this is the case, you could tell Macrium to backup just one of the drives, if all you want to backup is your data or your OS. In fact, I back up one drive at a time, rather than all of them, because Macrium seems to work better that way.
Since apparently you have three drives, you could power down, disconnect your data and Windows 10 drives, then do a clean install of Windows 7 on that drive. In this way, there is no way that the data or Windows 10 drives would be affected by the reinstall.
I have three drives in my computer: one for data, one for Windows 7, and one for Linux Mint. I have installed a SATA power switch so that I can switch the drives on or off as needed:

(I always power the computer down before switching any drives on or off.)
The data drive stays on; if I want to switch from Linux to Windows (or vice versa), I shut the computer down, power on and off the appropriate drive, then power on the computer. Like magic, I am in the other OS; and my data is always available, because that drive is always on.
If you had a SATA power switch like I have described, you could turn off all drives except your Windows drive, then power up and do a clean install of Windows 7. Then power down, turn on your data drive, then power up the computer. Your data would have been totally shielded from the clean install, then available once the install is done.
