Question Editing an OS drive

[hankjob]

Will my Windows 10 PC try to format a Windows 7 drive connected via an external USB harddrive enclosure?

Not unless you tell it to.

U will only be asked that if after hooking up the external, Windows can't recognize the drive as anything its knows, then u have the option to say NO, not in your life!
