Reset PRAM and NVRAM
If that didn’t work, then restart your Mac in Safe Mode. To do so, make sure that the computer is shut down. Press the power button. Immediately after you hear the startup tone, press and hold the Shift key. Release the Shift key when you see the gray Apple and progress indicator. Let the Mac boot up to safe mode.
If Safe Mode doesn’t work, run Disk Utility in Single User Mode. Follow the steps below;
Turn your Mac off. Turn it back on and this time hold down the Command (Apple) key and the S keys at the same time. Then type the following command... /sbin/fsck -fy (note the space between fsck and -fy) If you can't run /sbin/fsck -fy then type only fsk -fy Hit return and the disk utility should run and let it finish. When it finishes and there is no error, then type reboot and hit return. Let the Mac boot up. (Disk Utility will fix all system errors, bad preferences files etc)
Please let me know if those steps didn't work, so we can continue troubleshooting.
no success so far, I got it in Single User Mode and have text on the screen with errors trying to load the drivers and the wireless keyboard is not able to type any text.
The reinstall of the 0SX failed overnight,,, the screen was full of failed install messages. Since I was sleeping during that time and not sure if any messages came up before the failure I will try to install again this morning.
most have been but some very important ones were being worked on that day and would be lost so thats not an option yet.
After going through the installing process of 45 minutes the time bar is totally blue and the time remaining is now increasing per minute (now up to 10 minutes).. so not sure what to do.
Yea, it just kept adding minutes to the time and when it got to - 50 I shut it down. I was able to recover almost all the data with the last time machine backup fortunately. Doing a clean install of SL.
Yes, it seemed to get worse after every attempt too so it was a necessity to do it. Yes, I erased the HD with the disk utility first then went for the install. Three cheers XXXXX XXXXX Machine as it backed up just before things went south on the HD so everything was there... at least what I remembered and needed. Thanks for the help Ashik.
I did a disc repair again and then a clean install of OSX snow leopard last night. This morning I checked it and the screen showed the OS had been installed successfully. When I restarted the computer it seemed to start up slow and then went into the welcome screen with all the languages saying hello but the screen would freeze then start and freeze then start all through the introduction so every thing was jerky visually but the sound track was fine. After that it froze and then went to a black screen for about 30 minutes. I restarted it and the gray screen with the apple and time indicator came up and has been going on for 20+ minutes. Looks like I'll have to take it in for diagnostics and repair after all. Bummer!
