Windows 7: Windows upgrade problems. Windows XP to Windows 7

Windows upgrade problems. Windows XP to Windows 7

Hey all. I'm rather new here and am semi-competent with computers, but I have no idea what to do here.

One of my laptops is running Windows XP x64 and I actually DON'T have a copy of Windows 7. After the laptop originally got a virus I downgraded from Windows 7 Professional 64 bit system. But for some odd reason, now that I downgraded it's not picking up wireless capabilities, so I'm hoping to upgrade. I downloaded an .iso file, simply because I used my friend's 7 disc to upgrade my other laptop. He lost the disc, so I'm using an .iso as I said above. When I go to start the .iso file I get the following message: Windows Setup: This installation disc isn't compatible with your version of Windows. To upgrade, you need the correct installation disc. For more information, check your computer's system information. To install a new copy of Windows, restart (boot) your computer using the installation disc, and then select Custom (advanced).

I have no idea what to do now. I'm upgrading to the EXACT same OS that the laptop had previously. I've tried using Windows Ultimate and Windows Home Premium 64 bit and I get nothing, the same stuff. Any suggestions? As I said, I do not have an actual disc, and I'm running off of an .iso file. Help would be much appreciated seeing as how I need this laptop fixed soon. Thank you!

So this laptop originally shipped with Win 7 Professional 64-bit and that is what the existing Product Key is for?

If so, the next question would be where did you get the ISO? I assume you burned the ISO to DVD?

You can't run off an iso file. You need to burn a DVD and boot it to do a Clean install as there is no upgrade path from XP to Windows 7.

Use ImgBurn and burn the DVD at the lowest available speed, usually 4X.

Boot the DVD and install. The only option you will be offered is a Custom (Clean) install.
If you have any data on the XP computer you don't want to lose, back it up first.

Is the Product Key on your COA sticker readable? You will need it to reinstall. It will look similar to this and be located on the bottom of laptop:

Windows upgrade problems. Windows XP to Windows 7-1270558000_86224332_1-pictures-buying-windows-7-prof-coa-sticker-only-100pcs-up-needed.jpg

Then follow these steps to clean reinstall with the latest official ISO download with SP1 for your version: Reinstalling Windows 7
