I encountered a problem while re-partitioning my computer the other day, shortly after installing Windows 7, and now I'm unable to reinstall *any* version of Windows on any of the three hard drives in my computer.
When I try to install from scratch - which I'm only doing because it's proved impossible to reinstall over the top of existing installations - using the Windows installation disks, I'm informed that "Your product key cannot be validated. Review your product key and make sure that you have entered it correctly."
That specific wording is from the Vista installation routine, but a similar formulation comes up in all three versions I have - XP, Vista and 7.
I know that the product keys are in fact correct - I've used them before on the same computer - and all of these versions of Windows are authentic, the original disks and purchased through officially approved channels.
Looking up this issue on the web, none of the scenarios mentioned appear to apply. One suggested for Vista is that the installation disk is pre-service pack 1 and the product key was issued after that, but that can't be the cause here as the same thing is happening in XP and 7 too.
Looking in the BIOS, everything appears to be normal. And looking at the disks using a boot CD for the two partioning programs I have - TeraByte BootIt NG and Acronis Disk Director 10 - nothing appears to be out of the ordinary. All three internal disks are functioning and their booting order in the BIOS is the same as I had them set up originally.
My system's spec is as follows: Intel Core2 Duo E6600 @ 2.4GHz, 4GB RAM; Intel Desktop Board D975XBX2; ATI Radeon X1050 graphics; three Seagate Baracuda hard drives (80GB, 250GB and 1,500GB); Microsoft Windows 7, Vista and XP.
