I get this error when i try to boot


missing file - /Library/Preferences/SystemConfiguration/com.apple.boot.plist

The same happened for me twice already, still dont know the reason.
If you have backup copy of this file - instert installer dvd, boot into single user mode and copy the file back to where it should be. Thats how i fixed it the 2nd time.

For the 1st time i just reinstalled the system...cant propose anything else. Or you can recreate the file somehow ( or copy it from another system but have no idea if it would work )

Hello, I have your same acer model 5520. No pbm for booting at all, it takes a while but it goes on. At start-up I press F8 and then I type -v -x, all goes well:)
However It stops further ahead for me... :( when I have to choose where to install Leo the installer does not see my HD at all!! If you can go ahead with booting and get to this part please post some feedback!

Well I have updates about AcerAspire 5520!
The SATA problems remains so I chose to install in external USB HD. I used kalyway dvd installer, with minimal specs for install (kernel sleep, smbios default by netkas, amd patch) and bingo! (Y) I got it! OS was installed correctly, restarted with -f at boot prompt and there it was the os welcome movie!
Some tweaking is required now:
-internal SATA HD and DVD-CD drive are not detected
-no audio
-no internet
-resolution set at 1074x768 when it could go to 1280x800

The first pbm is the most relevant as I need DVD-CD drive to access iDeneb DVD installer for some kext I need now that is included there ... keep looking for info and trying! any tiny piece of advice is welcome :)
My hardware report is attached

So we are still in the dark. I was hoping that the live dvd would solve some problems, although I think that we don't have some drivers for our laptops.
