After a few days of good experience with Yosemite, my Macbook pro cannot boot anymore. After 30 or 40% of boot, it just restarts. Here are what I did to fix it:
- Booting to single-user, runnign
fsck -fy, since the laptop fallen one day or two ago and I was suspicious about hard drive. But
fscktold everything is fine with my hard drive. I don't think it is checking bad sectors.
- Resetting PRAM
- Booting to Recovery, checking hard disk via Disk Utilities
- Reinstalling Yosemite from OS X Utilities
Now it does not even boot into recovery (reboots after 30%).
My last try was to verbose boot, and the last message printed out before rebooting was:
VBoxDrv: Failed to open kernel symbols (rc=-102)
In another try, the last message was:
VBoxAdpDrv: version (some number)
I had VirtualBox installed on my MacBook and worked prior to upgrading to Yosemite (in Mavericks). I did not check it in Yosemite.
So my question is: can VirtualBox prevent Yosemite from boot? Can I uninstall it using single-user boot (which is the only successful boot on my computer now)? Or do you have a better idea to get it fixed?
