Well your going to have to get an older BIOS back on your Notebooks hard drive the BIOS file needs to be named G75VW.bin then use the Ctlr + Home. I have been running 210 since it came out. Havn't seen any improvement in 222 or 223 and have seen a lot of bricked Notebooks Pick out the one you want. mount our hard drive some where so you can copy or paste the file on the Root of your hard drive. Its your only hope. Then go to
http://windows.microsoft.com/en-us/windows-8/create-reset-refresh-media and download the version of window you have a key for? The embedded key most likely is a core 64 bit, If you have a Pro key use
