![]() Tried emptying EFI partition, playing with EFI/Mac-OS partitions boot flags, Zapping the PRAM, nothing still allows me to boot either from Mac-HDD or any Mac-Bootable-DVD.Ĩ. > Looks like most of my problems are due to the fact that I have Mac-Mini which does not allow eject/replace of DVD from command prompt / out side of Mac-OS-X.ħ. So I didn't yet try other popular rescue media - as I suspect that is not the direction I need to go into. Suspecting EFI is now corrupt, I tried other 'hacks' like:Ħ.1 eEFIt Boot Disk - which does not work at all,Ħ.2 Empire EFI w/ Chameleon - not sure how to proceed with options presented - trying either does not work,Ħ.3 Super GRUB2 - boots fine, but attempting to boot from Mac-HDD fails after a couple of seconds,Ħ.4 Boot-132 - boots fine, prompt asks for input, but then I cannot eject/replace the DVD due to Mac-Mini (lack of) design,Ħ.5 Ubuntu 11.04 / 11.10 - still boots fine - just that I cannot go into Mac-OS-X from here,Ħ.6 TechTool Pro bootable DVD - which used to boot fine earlier stopped to boot.Īs you can see, none worked successfully. Googled and learnt that just attempting to boot using Ubuntu DVD can take away ability to boot using Mac bootable media - possibly due to EFI internals. However using Ubuntu's bootable disk, I could access Mac-HDDs contents - and was able to successfully back-up *all* my important data.Ħ. However this step took away my ability to boot from Mac.ĥ. Anyway, attempting volume repair that way couldn't fix the problem as well. I had that handy, but forgot to disable HFS+ journaling before attempting to fix the problem. Started looking into forums, learnt that someone had successfully repaired this problem using Ubuntu 11.04 install DVD (i.e., without installing the Ubuntu, but just using its 'try from DVD' feature). (How do I claim my lost money with TechTool Pro - suggestions appreciated as well).Ĥ. Sent the details to TechTool Pro support team, they couldn't help either after a couple of e-mails+data exchange. Again, it's surface scan suggested disk hardware is 100% fine. Tried its bootable DVD only to learn that TechTool Pro cannot fix it. Started googling and had to choose between and, opted for TechTool Pro. I lost the DVDs that came with this Mac Mini, so the option to boot from that DVD and launch Disk Util etc. Volume Repair never worked, since OS X was installed on the primary disk. Surface scan said disk hardware is 100% fine. Performed Mac's Disk-Util check and used to display "invalid directory item count, should be 31 instead of 29". ![]() My best guess is that right after the use of Carbon-Copy Cloner (but I am not 100% sure) it all strated to happen.Ģ. When trying to boot, it would show a progress bar for about 5 minutes - I am assuming that was disk-consistency check being performed. All of a sudden, one fine day, on start up, my Mac Mini strated to shut itself down without no apparent reason to me. So please, any casual beginner, please do not demoralize with something like "cannot be done" etc.ġ. I always very much appreciate the efforts of true geeks. The OS/installer from the DVD does not seem to boot either. ![]() Once you look at the program and choose the Source and Destination Target I think just try it and should be self explanatory more than words.I have Mac Mini (late 2009) which does not boot anymore and I need to install Snow Leopard using retail DVD (version 10.6).
