I built a new system a few months ago with Vista 64, which came with free windows 7 upgrade coupon.

Got my Windows 7 upgrade disc a few days ago but it will not install. After the first reboot of the install process it fails with the error message

"Windows cannot find the partition selected for installation"

I am running 2 partitions.

1- is 1 160GB HD with Vista and other programs
2- is 2 500GB HDs in a RAID mirror with my data

I've tried updating the HD drivers, but Vista says all drivers are up to date. Any help would be appreciated.

PS I am not a computer nerd, so please explain everything very clearly. Thanks
