    I am not sure if I am in the correct category(my apologies if not) but this is a frustrating problem because I cannot access my windows. I was able to boot windows 7x64-bit just fine until my bios got updated(I guess) to this Gigabyte UEFI DualBIOS. The error I'm getting is: "Reboot and Select a proper Boot device or Insert Boot Media in selected Boot device and press a key". As I understand it won't find the hard drive in which windows are installed(?). The only devices that show in boot sequence are P3:Optiarc DVD-ROM DDU1675S and P0:MKNSSDCR180GB. I'm using Windows Ultimate 7x64-bit and Intel core i7-4771 processor. Can anybody help!??

    That probably has to do with AHCI mode or not. I would try with and without. Also you want to boot as if Ide. Make sure the Secure Boot is not enabled also if there as that really only works with Windows 8.

    Thank you very much for replying though I just fixed the problem. The issue was electronic and nothing to do with BIOS/windows. Actually I fixed it by swaping the cables of my hard drives with each other. You'd think that since that worked I would be able to boot the windows but end up having the other hard drive (the P0:MKNSSDCR180GB that was recognized by BIOS before but not the one that contains the installed windows) not working since logically there must've been something wrong with one of the cables, but I just switched them and now they both work! I have absolutely no idea how that happened but I'm glad it did
