Upgrade Vs Full version

can someone please clarify a few things for me.

1. the upgrade disks and the full disks are exactly the same EXCEPT the upgrade one requires proof that you own a copy of vista or xp.

2. what kind of proof does it require? does it just ask you for an XP/vista serial during the install?

thanks

Welcome to Sever Forums, fadetoblack.

Actually, you don't need any proof.

Check out this tutorial - Clean Install with a Upgrade Windows 7 Version

thanks for the reply. it looks like you need an existing copy of windows installed to follow the steps in that tutorial. i have an oem copy of vista ultimate but wanted to install win 7 on an empty hd. in that case, what kind of proof would it require?

No existing copy is needed. The note under Option One says:

This option has been confirmed by me to be able to install from a formated blank drive or system, and install the retail upgrade Windows 7 and activate it without doing anything else.

oh ok sorry i missed that. so then what exactly is the difference between the upgrade and full disk?

1-Yes

2-an activated OS on the computer. No serial numbers

This is what the differences between upgrade and full are supposed to be. REcent evidence suggests there is less diferences in reality

1. Correct.

2. The Upgrade version checks for an INSTALLED qualifying OS.... XP / Vista. It doesn't ask for a serial....nor does it ask you to insert your XP / Vista disk for verification.

There are ways around this. You can install the Upgrade version without entering your Product KEY. Then use the old Double Install Method.... or better yet, use the method on Paul Thurrott's site:
