davpel Posted May 7, 2015 Share Posted May 7, 2015 I recently set up my Hackintosh with a Gigabyte Gaming 5 motherboard dual booting between Yosemite and Windows 8.1. I have 4 hard drives with multiple partitions on each. Everything was working great. I had set the boot priority to for the OS EFI and successfully booted into Clover each startup.Last night, however, Windows downloaded system updates and installed. When I was prompted to reboot, the system quickly flashed the Gigabyte flash screen and then went right back into Windows without sending me to Clover. So I assumed Windows had taken over the #1 boot spot and went into the Bios to fix it.Here is where the problem lies. When I boot into the Bios, it now shows over 500 different boot options, many of which are simply listed with garbled text/characters! Even worse, when I try to set the OS EFI containing Clover as the #1 option and then select save, the system freezes every time an I am unable to get that option to stick.Any idea what happened or how to fix this? I can still get into Clover manually by hitting F10 on boot, but this isn't optimal. Moreover, it can't be good for my Bios to (falsely) see that many drives.

crusher Posted May 7, 2015 Share Posted May 7, 2015 Try to resert CMOS remove battery and pull the cable from the power supply wait one min. After back battery and cable. Ok turn on PC and settings your bios. This will not work properly? Then take and download the BIOS ROM and flash your bios with QFlash. Good luck.

I'll give this a try when I get home from work this evening. Really hope I don't have a bad mobo. This was my first ever computer build and it will kill me to have to essentially start over.

davpel Posted May 8, 2015 Author Share Posted May 8, 2015 whether it works for you or not? Hi Crushers. Resetting CMOS did not fix the problem, but flashing an updated BIOS did temporarily resolve the issue. However, once I booted into Windows 8.1 again and used it for awhile, the problem immediately came back. One thing that I noticed was that while in Windows, I made a bootable backup of my Windows drive using XXCopy to a different internal drive. I think this may have precipitated the problem. Nevertheless, for the time being I have wiped Windows off the SSD and will be using this Hackintosh solely for OSX. This way I can confirm that it is my Windows install which was causing the problem. On that note, I originally installed Windows 8.1 first, before OSX and it was done as a UFEI install. Could that be an issue? Thanks again for all of your help.

crusher Posted May 9, 2015 Share Posted May 9, 2015 Ok. Create UEFI windows bootable USB with rufus and again install of windows. Try this method. Which method of install UEFI Windows you use?

And look on my previous post how to settings your bios. I thought most people recommended installing Windows in legacy for dual-booting? That's how I originally installed it. I would use Rufus except for the fact that I'm in an all OSX environment and have no access to a Windows machine until I get dual-booting working -- ironic, no!
