Windows 7: How do I clean install Windows 7 upgrade to new mac?

How do I clean install Windows 7 upgrade to new mac?

Hello, I have kind of a complicated question...
Is there a way to install Windows 7 Professional Upgrade as a clean install to Parallels on a Macbook Pro? I purchased the Windows 7 Professional Upgade as part of the "Ultimate Steal" student discount program which requires that I own a copy of Windows XP or Vista. I do own Windows XP. I have a genuine product key and product ID.

Here's my situation:
I have 2 macbook pros. One very old (2007 macbook pro) with Windows XP Professional installed. I have the Product Key and ID but no install disc. (I lost it)
One new macbook pro (2011) and a bootable windows 7 professional upgrade iso (and have it burned to a DVD as bootable). I have an authentic product key and product ID that microsoft emailed to me. I ordered a backup installation DVD but that won't come for a few days (hence why I made the iso a bootable DVD)

So technically I own Windows XP (on one mac) and want to install a clean version of Windows 7 Professional on a new mac. Anyone know how to do this? When I try to install Windows 7 using the iso or the DVD Windows (in parallels) tells me I need a prior version of windows installed. The "Ultimate Steal" website says that there are no returns allowed and no where on the page does it say I must upgrade from a computer that has XP or Vista on it. It only specifies that I must own a valid XP or Vista license. I really hate how Microsoft makes this so difficult.

Your help is greatly appreciated!

Had i known that Microsoft would make this so difficult I would not have purchased Windows 7, but there are no refunds.

here's an idea I had if worse comes to worse... If there isn't a solution to the above, how would I go about downloading a Windows XP Professional ISO to install using parallels on my mac (and deactivate windows on my older laptop), reinstall windows xp on the new computer. Problem is I don't have a install CD so I would need a source for a legit full iso.

oh, and I also have a normal functioning windows 7 home premium laptop if I need to use windows 7 to download anything (in addition to the 2 macbook pros i listed above)

Hello otissmithd, welcome to Seven Forums!

I have no idea at all if this will work on a mac but since you own a qualifying Windows version, have a look at this tutorial at the link below and be sure to post back with any further questions you may have and to keep us informed.

unfortunately none of those options worked :/

parallels automatically opens and tries to install windows 7 when I open parallels

Is there any way I could get a legit iso for XP professional?

activation was successful! Thank you very much! For the record, I did the option 1 and had to do the registry work around.

Quick question: I had to download the registry mod and open the command prompt and follow the steps; is there any chance that Microsoft would invalidate my copy of Windows 7 or for this to backfire in the future?

Thanks again guys!
