[Solved] Cannot boot after installing Nvidia Web Driver GTX 750 w/o UseKernelCache=No

[Badd_Blood]

My system was working great until I installed my GTX 750 card. I installed the Driver for 10.10.2, plugged in the card and enabled the driver. After rebooting it now is very slow and freezes at boot screen with a circle with a line through it. Using -v is says "still waiting for root device".

I am able to boot by adding UseKernelCache=No to my chameleon plist, however this causes it to take 2 minutes to boot instead of 10 seconds on my SSD. After the slow boot everything works. Thank you for the guides on here so far, but I really could use some advice on how to fix the KernelCache or speed up boot time.

Here are my Chameleon settings:

Cannot boot after installing Nvidia Web Driver GTX 750 w/o UseKernelCache=No

Finally seemed to fix all issues!

As for UseKernelCache: Downloaded Kext Utility and repaired permissions. UseKernelCache=Yes now boots.

For slow boot time: In the BIOS I disabled UEFI and used Legacy only, also disabled Intel Integrated Graphics (not sure which fixed it).

7 second boot time, thank you Lord!
