I am resetting my sister's MBP late 2010 to factory defaults. It's all backed up. I'm reinstalling from the recovery partition currently. Before I started working on it today, it had the very descriptive problem: "wouldn't boot."
I previously had installed Ubuntu on this since she wanted to try it, and it was run as a dual boot system for about a year. Now, the disk space needs to be brought back into Mac, since the HDD was almost full. To top it off, Grub/rEFInd seem to have gotten lost at some point along the way during an upgrade, so Ubuntu is functionally gone anyway.
I did some research, took it into safemode, which did boot, backed up, and then booted into recovery (
r), opened up disk utility, formatted, and clicked the
- button on the three Linux partitions (boot, swap, and file system, I believe).
Now, when I look in Disk Utility, on my 320GB HDD I see a ~200GB Macintosh HD (which I have erased and formatted), a Recovery HD, and there's over 100GB missing. There's no other partitions, and I can't expand the Macintosh HD partition.
Immediately after removing the partitions, I had a Partition Table error when I ran Verify on the HDD. Repair kept failing, so I rebooted into recovery mode and ran repair. Now there's no error, but still no drives.
When click on the HDD and go to the Partition tab, I can choose 1 Partition, which does correctly show 320GB. Otherwise, I can't find the lost 100GB. I tried enabling debug mode (something like
defaults write com.apple.DiskUtility DUDebugMenuEnabled 1) and checking making everything visible, but the partitions still are not visible.
- Is it possible to reinstall without the disks (not my machine, no idea where the disk is) if I change the drive to 1 partition and format it? Am I going to be able to do this from Recovery Tools?
- Following Unable to increase partition size with subsequent blocking partition, I believe after reinstalling OSX I will be able to use a 3rd Party utility, probably gParted, to move stuff around on the drive. Can I use gParted from an Ubuntu live disk for this?
- Is there a way to make the partitions reappear is disk utility so that I can at least format them?
After reinstall finished:
Edit: Per the comment, here's the output of

And a screenshot of DiskUtility's output. As you can see, my 320.07GB HDD has a partition just shy of 217GB
Macintosh HD. The
Recovery HD partition is 654MB, leaving 102GB lost.
