Still Waiting for Root Device

[achsta2004]

Hello,

i have Mountain Lion 10.8.1 installed on my Acer Aspire 5755g, however when the operating system tries to load i get a still waiting for root device error. Nevertheless, it will boot perfectly into safe mode. Any solutions?

Thanks in advance.

Hi,

others have had the same problem, including me. I have to boot with UseKernelCache=No, or -f. Alternatively, I can use IOAHCIBlockStorageInjector, but for some reason that makes my optical drive disappear.

I have create my Boot USB with UniBeast and Mountain Lion and I am getting the same error.

I have search all over the internet and I didnt find any solution yet...

Where should I run these:

cd /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS
sudo mv IOAHCIBlockStorage IOAHCIBlockStorage.origsudo cp IOAHCIBlockStorage.orig IOAHCIBlockStoragesudo /usr/bin/perl -pi -e 's|\xbb\x4b\x00\x00\xeb\x03|\xbb\x4b\x00\x00\xe8\x01|g' IOAHCIBlockStoragesudo /usr/bin/perl -pi -e 's|\x74\x0e\x48\x8d\x3d\xb2\x91\x00\x00|\xbf\xc8\x00\x00\x00\x90\x90\x90\x90|g' IOAHCIBlockStorage sudo touch /System/Library/Extensions

These are the errors I get, if it helps....
