shrieken213 Posted June 18, 2014 Share Posted June 18, 2014 Hi! I recently switched to Clover from Ch*mera/Chameleon and am struggling to get dual boot to work. The two OSes are on separate GPT hard drives; Clover is installed currently to the Mac hard drive but not the Windows 8.1 drive. I also have the UEFI version of the Windows 8.1 installer on a USB 3.0 flash drive. OS X boots fine with little to no issues (only thing not working is ALC892 but I have an external audio interface), but the problem comes in when I try to boot into Windows. First of all, I can't boot into the Windows 8.1 installer from Clover. Every time OsxAptioDrvFix causes an error with "more blocks allocated than requested" or something like that, which is very weird. And I can't disable the driver because it's necessary for my board. To boot into the installer, I have to go to the boot devices selection of the BIOS/UEFI before Clover loads. I also discovered that installation was impossible when other hard drives were connected, so I had to disable those ports as well. Once booted into the UEFI USB installer, there are no problems. Then once the install finishes, I can boot into Windows fine from Clover. But the moment I try to install something like the GeForce drivers it freezes up and forces a reboot. Any subsequent attempt to boot Windows from Clover results in no video output from the GPU and only half the drivers loaded (keyboard caps lock light doesn't toggle). Again, when I select the default Windows bootloader instead there are no problems at all. One exception still stands, and that is the startup options menu that comes up every 3 failures and Safe Mode that I am using to type here. Since Safe Mode boots fine, this issue seems to be a driver causing a system crash on boot, but I have no idea how to fix it. Can any experts help me out with this? Thanks!

shrieken213 Posted June 19, 2014 Author Share Posted June 19, 2014 The driver that I most suspect is the latest Nvidia GeForce driver (337.88 I think?) which causes the boot-time crash. Not sure, though. Link to comment Share on other sites More sharing options...
alexanderq Posted June 23, 2014 Share Posted June 23, 2014 I don't think that Clover can interfere with windows but if you want someone to help you on that when you are on clover's gui press f5 and it will save preboot.log (but only on fat32 filesystem) and then post it here.
