Unplug your Hard drives Unplug the Dom plug a new hard drive in Sata0 plug an Usb-DVDrom witht W7 Dvd on it plug a Keybord and a mouse. plug a PCI Video Cards mine was a Matrox MGA Millenium (whooooo that's oldddd) In Bios select USB dvd-rom as boot device.
all done you just have to boot and install W7.
It works like a charm , with all hardware ok!
in hardware list i could see there is a video chipset on the motherboard and as the N5200 there is a place to connecte a VGA connector.
So it could be done for other OS.
For me it was just a test i went back to thecus OS waiting NEW UPGRADE.
