I have a MacBook with OS X on one partition, a few other partitions and a Bootcamp Windows 7 on another partition.
Right now, I can boot into Windows but I cant boot into OS X. I am typing this while using Windows as the host OS.
When I boot into OS X I get the prohibited sign, and boot into OS X via Safe Mode, I see
hfs_mountroot failed: 5
cannot mount root, errno = 19
At first glance this seems to be an I/O issue, that my harddrive is dying or something, but the Windows partition works flawlessly.
So something has happened to the boot on that OS X partition. Other places on the net say the drive is done and that I need to image it or that I need the OSX startup disc but even then its a gamble. But I disagree since it is clearly that one partition that is having some issues with its boot protocol and not the entire hard drive.
To further illustrate my point, my Windows 7 has MacDrive installed, and I can browse all the files on my OS X HFS+ partitions!
With that in mind, is there anything I can do to get my OS X boot partition to work again? Thank you!
