Hmm, i guess you can try booting in safe mode maybe you have more freedom then. I have to go now, i'll think about this and post later.
OK, i'm back now
@dominusdj, multibooting is easy when you got only MBR.
1. Install OS X on MBR Partitioned HDD
2. Install Windows
2.a Now, after installing Windows, your laptop will boot automatically into it.
3. Burn rBoot LE (Lion) #####
Legacy (Snow Leopard)
and boot off it intro OS X.
4. Now you must re-install your bootloader (chimera) and voila, you got Windows and OS X working on the same drive
@bastisk8 A picture or a transcript of the Kernel Panic screen would be great, i need to know whats causing this. I'm planning on making a L502x Only boot CD so more info will be valued.
@Kirky Try using terminal or booting with -v -s and use the commands there. or boot with -x maybe that will allow you to move those files. Or build the kext cache manually (kext wizard has that option (installation > drag all kexts from /E/ and /S/L/E into it, and check extensions.mkext on desktop) when its done, move it in the proper kextcache location (/S/L/caches or something) repair permission manually with terminal, and reboot with UseKernelCache=Yes
