Windows-10 Upgrade without an Existing Booting Operating System
I have a windows-7 platform here which is bluescreening on boot.
I intend to upgrade it to windows-10.
If I boot with a windows-10 ISO, will it be able to upgrade it by detecting the existing Windows-7 or does the upgrade has to be started from within Windows-7, ie meaning I first have to fix Windows-7 to have it boot up and then upgrade?
Is there any way around fixing the Windows-7 and still be able to do a gratis upgrade?
