Windows 7: need to uninstall win 7?

I was running 32 bit Vista ultimate. I tried installling 7 from a disk i burned from MSDNAA but apparently it didn't work. so I used the Enterprise 90day trial version thinking my product key would work to go to premium. Apparently you can't go there from enterprise so now I need to get rid of enterprise and get 7 professional which I have a product key for. I did a custom/clean? install and used windows easy transfer and have a windows.old folder on an ext HD. I also copied everything using complete pc backup on another HD. so I am pretty sure I have covered my bases as far as saving what I might need. I have my original vista disks and also the ultimate disks but I don't know if I have the product key for ultimate, I haven't checked. but if I am only going back to reload win 7 pro do I need to go to ultimate or could I even use the recovery partition that came on the laptop from dell? last question, do I need to transfer everything now before I go back to vista or since the windows.old file is on my ext HD can I just transfer once I get the correct version of Win 7 installed? I know this is complicated and I have looked every where but haven't found the exact info I need just bits and pieces. Thanks in advance for any help.

Welcome to Seven Forums, mrscullen.

I highlighted your two questions, which are related. The quick answer is that there is no need to re-install anything but the copy of Windows 7 Professional that you want to use.

You can even get rid of the recovery partition, if you want.

(Note: If you are using the Upgrade version of Windows 7, you can do either a clean install, custom install, or upgrade install (The links point to tutorials here on how to do each.))

You kind of lost me with all these different versions.. But I think you want to have Pro installed Do you have a Bootable DVD of Windows 7 Pro that you can set your DVD drive to be the first device to boot from ?

Ok because I posted a similar question on microsoft dot com and was told I had to go back to vista first. when I asked a followup question I got no answer. so 'i can just use a new dvd with the file from msdnaa and boot from that?

There is no need to go back to any prior version of Windows. If you have a bootable DVD, just go for it.

(If you have just the files from MSDNAA and need to make them into a bootable ".iso" file, there's a tutorial here on how to do that. Make bootable iso from student d/l)

not one that works, I have files from dig river and msdnaa.

You should do the tutorial as TheSchaft talked about above !
