Went back to factory settings on the netbook. It looked fine with Toshiba icons and the Explorer icons waiting to be updated. I then got a blue screen and the netbook shut down. when I turned it back on I got a DOS screen with :
Realtek PCIe FE Family Controller Series v.1.22
PXE-MOF: Exiting PXE ROM.
Operating system not found
Any ideas from here??
