Thanks for your insighful comment: The recovery disk images are completely useless because neither the SATA CD nor the SATA HD (or any other post IBM-PC device for that matter) work when you reinstall Vista.
It's also interesting that you think you can prove Vista is perfect by telling us that you could not install Windows 7 correctly.
Acer doesn't ship CD's with their desktops, and when the harddisk dies there's no drivers on that disk either. You can find SATA drivers and burn them on CD if you have a different system available, but the SATA driver messes up the Acer SATA CD-player, so you then need a second CD drive to continue the installation.
You clearly haven't installed Windows on an empty system disk, as you seem to be unaware of these amusing practical details.
If you need a week to do that you obviously haven't tried to install Windows (say, Vista on a SATA only Acer system with nvidia chipset, endless amusement of the kind I haven't seen in Linux since the early nineties....)
