    Unable to install/use GeForce GT640 on MPG645 (Medion)


    So I bought an MPG645 which is actually a Medion and I have a GeForce GT640 (which should work fine with Windows 8). First time when I installed the card I got the beeps (long short short) and nothing happened. Went into bios and noticed I had an "OS selector" for either Win8 and Win7/OtherOS. Setting it to the Win7/other OS solved the beeps and I could use my GT640. Now yesterday I had a big problem resulting in me needing to get back to factory default so as I am used from the previous OS setups I removed my videocard, set the bios back to original and re-installed my system

    Then I wanted to put my card back.....black screen (after setting the OS back to WIN7/otherOS). tried it without the card and got a message telling me I had to use the proper boot device, hit any key and try again". The solution I was reading on the nvidia page told me to disable secure boot, no solution.

    Basically, it has worked fine until I had to reset my system and now whatever I try I can't install my graphics card

    Thanks to a poster on the geforce forums I found the solution because he used some nice screenshots of the settings needed which made it all very clear where to use the eufi and where to use legacy options. Not sure if this works for any system but at least it worked for my MP/Medion desktop pc. Happy to pass on the screens for those with this prob

Solved Unable to install on GPT disk in Installation & Setup
I'm trying to install the Windows 8 x64 RC on a 200GB partition on a 2TB drive. I'm installing from a DVD, and it tells me it can't install because the disk is of the GPT partition style. I was under the impression that this was the style it was supposed to be. Any thoughts? Thanks, Christian
