Hi,
I have a pretty old laptop (HP Compaq nc6400) in my home, with Windows 7 installed in it. I want to install Windows 10 Insider Previews on It.
Is it possible to copy all the data including Windows 7 to an External Drive, clean install Windows 10 on internal drive(this drive will be most used, as a regular drive), and boot Windows 7 from External Drive when needed?
 
Solution
Simple answer is no it wont boot into an external drive. If you want both operating systems to work correctly-1 back up any important data to the external then -2 use a partitioning program to create 2 partitions -3 install your OSs 1on each partition and 4 use a boot manager to choose which OS to use.

Okay. Thanks :)
But, actually to be honest, the pc contains some old games which may not be genuine and I've heard that Win10 scans the pc frequently and breaks any software found doubtful that's why my plan was that when Win10 loads up in my pc there shouldn't be any such older software in the harddrive that's why...
What you guys think of it?

Hi,
Just to do an experiment and see what practically happens, I connected my internal HDD externally to my friend's laptop and tried booting from it, it didn't said Windows won't boot from external but ultimately resulted in it. I chose Windows's Repair and boot option, tried various combinations but same thing every time. Hence Proved
