LEO won't load to desktop, please help

[MrRoper]

So i was popping back and forth between osx & windows( i use my bios to switch HDs) and i accidentally started booting into osx, instead of waiting and rebooting , i decided to hardboot the machine, which i've done in the past many times without any problems. (but also a new bios, which is a different headache but may have contributed to this problem) anyway this time, something got corrupted on my osx ide hd and it will not load to osx desktop anymore.

What happans is, OSX loads the all the extensions normally and i get the flash of blue osx background, the cursor shows up and then i get the error.. (I've attached a copy of the osx logs below in a zip file) it then goes into a loop where it continually trys to load loginwindow.app i'm guessing, then crashes and lets me know its posting the error to the crash logs. . . .

 

I can:

boot to single user mode, fsck -fy

boot to install dvd and diskutilities/repair permissions

I've tried booting with -x -v with the same loop/crash as described above

i downloaded a copy of loginwindow.app and replaced/renamed the existing via macdrive on the pcside

 

 

I'm not sure where to go from here, i defer to the experts...

if I can recover this install would be great, seems to want to get to desktop just won't "turnover" if i can use that analogy...

 

Please help, any help is greatly appreciated

thank you

I think you have damaged file system and when you repair it by fsck you lose some system files or bad encryption state.

It's impossible to understand what file is wrong. The only way is format partition adn begin from initial.

Try using the Repair Disk option from Disk Utility on the OS X Install DVD. I don't think it will do much thought because it does essentially the same as fsck -fy, correct me if I am wrong. If that doesn't work out, I think the easiest way would be to reinstall the base system from your OS X install DVD. It should leave all your files as they are, and just overwrite the hard drive with a fresh copy of OS X.
