I have a Acer Aspire 7520 laptop that used to have Vista installed. I've been playing with it some and installed Ubuntu some time back. Got recovery and system disks from Acer to reinstall Vista but keep getting a window saying something about windows/vista not able to install with this hardware. I haven't changed any of the original hardware and have reformatted the drive with both fat and ntsf but get the same problems with hardware message.
