Confused SSD won’t boot
Looking for a definitive answer to the following problem:
2006 iMac running 10.7.5 with 4 megs ram and 250 SSD
Upon reboot the system refused to come back up and gave what appeared to be faulty video. Since I already had one video card failure, I replaced the video card and rebooted.
System starts to boot and stops at the white screen with the Apple logo and the spinning vertical wheel lines. Will not pass that step.
Rebooted and went into Recovery mode. Ran simple repair options on the SSD with no results. I have the option to Restore via (old) backup on local Airport. Since I don’t really want to lose everything I used Disk Warrior and was able to easily gain access to the SSD. I then downloaded pretty much everything off the SSD so that I at least could retrieve documents I needed.
However, still cannot boot the SSD. From the various methods I have tried I feel confident that the MBR has been corrupted. I have expert experience with Windoze operating systems and have always been able to re-write the MBR to get an MS drive to boot. Especially if the data was not corrupted, as is the case with my SSD.
How do I re-write the MBR to get the SSD to boot? Or is there another method for gaining access without having to lose the data by re-installing the OS?
