I have a HP TouchSmart IQ700 that needed the SATA hard disk replacing. With a brand new formatted hard disk I inserted the Windows Vista x64 DVD and it starts to load.
It gets past the Loading Files screen (black screen, white progress bar) and the next screen changes to the Microsoft green progress bar and it hangs. I have left it for well over 30 minutes to make sure.
This hangs before I get any install menus/GUI for installing Windows Vista.
All peripherals are disconnected and the BIOS has very limited options. I have disabled power management and there are no USB options at all (was looking for the disable legacy USB).
The only item connected is the wireless keyboard.
