Grey screen when booting mavericks
2 2

Question

Hi, the other day installed mavericks as usual, everything went fine.

It worked a few days, and when i wanted to boot it again i got a grey screen after the apple logo. It doesn't worried me a lot because i get used to have a crash on my hackintosh everytime a month..

So, i decided to install it again, and after the install, again, the same problem.

 

I tried with so many bootflags, even -v, but the verbose mode it's ok, and then it goes to the grey screen, so in the verbose mode i don't see any errors.

 

PS: Also, i tried to install Mountain Lion, and i can't get video signal after install, the monitor (Screen) goes to stand by mode with my GTX 760.

 

Any info will be appreciated.

Those are the last lines before going to the grey screen. Sorry for the quality.

As i can see i have 'NVDAStartup: Official' and 'NVDAGK100HAL loaded and registered'

 

PS: And yes, using GTX 760 4GB

I had this problem and resolved it fairly quickly.  My graphics card is a Gtx 760 192bit (OEM) and had the same grey screen. What I did was once it was finished installing i booted using the line "GraphicsEnabler=No" and that fixed it. So it was trying to use my intel graphics every time it booted. I had to reinstall without the GraphicsEnabler line unselected at the install screen and it worked perfectly after that. Good luck. :D

I got Undefined error 0 when finish installing. But maybe it's because i tried with a different torrent. I will use the torrent that niresh shaid (Which worked for me the other day)
