Dual boot with windows.old

[AlexCold]

Hi guys,

I installed windows 10 over another windows 10.

Basically, I boot on the second windows 10. However, I still have the old windows (windows.old folder).

I need to boot on the old windows. I'm wondering how to do that, how to have the choice to boot between both windows.

Windows.old doesn't contain everything needed to boot of or run windows. If you want you can only reverse to old one while you still have it. Depending on your W10 version, it may last only 10days or a month and will be automatically removed.

In order to dual boot you will have to buy a new license for Windows 10 and then set up a new partition or a separate hard drive and install on to that. CountMike is absolutely correct.

With Windows xp and 7, when I install windows over the first installation and then when I boot I can choose between the old or the new installation.

Sometime I have to put the boot in msconfig, but everything works.

Basically, It's like 2 installations on the same partition.
