Hello! I was just reading through the comments but could not find a similar issue. So here it is - I am tried to install Yosemite on my Inspiron 3537 and I followed your guide till the 11th step and ran the HVT tool with selected options. But the problem is I am unable to continue and mount EFI partition as I have to always boot in safe mode for OS X to boot properly, and in safe mode mounting FAT32 volumes (EFI) is not allowed. Whenever I try to boot normally without the -x flag in verbose mode, OS X shows no errors in verbose mode and it passes, but immediately after verbose screen, I get stuck at a black screen with a white apple logo and a loading bar with mouse available, no progress in loading bar. If I boot in safe mode it boots fine, but then I cannot mount EFI and there is no graphics acceleration or sound. I tried many flags like GraphicsEnabler=No, -f, etc. but they don't work. How do I solve this issue? Can someone help me out?
