Can I install upgrade 7 Home Premium edition onto a pc with no operating installed providing I have the disc that it upgrades from ie xp pro or home etc / anyone tried this ?
Does the double-install trick made famous in Windows Vista still work?
As far as I can tell, yes. The short version goes like this: Boot from the upgrade media and do an installation without entering a product key. Then use the same media to �upgrade� your brand-new installation. I�m still testing this scenario but it seems to be supported. The technique is essentially unchanged from when I wrote about it shortly after the launch of Windows Vista back in February 2007.
