Install Windows 7 OS from .iso upgrade

[macanazon]

I am setting up my VM and am curious if anyone knows about installing Windows 7 without the disc.

I had vista, then upgraded to windows 7 on my PC...I have none of the discs and am only able to download the .iso file from the previous purchases section of the Microsoft store. This iso described as the Windows 7 upgrade.

Can I use this .iso file to install windows to my VM?

Thanks!

Did you actually try?

Typically with an upgrade ISO it expects to see a previous version of Windows already installed on the (virtual) hard disk, or it will prompt you at some point to insert the setup CD for the previous Windows version - as proof.
