I've run in to this before and the only solution I'm aware of is to reformat your file system. Here's what I suggest you do: Boot off of your OSX install media and use Disk Utility to clone your OS image on to another drive. Reformat your main drive with the file system you want Restore the contents of your backed-up system to the main drive. You could ...

I had the exact same problem and searched the web until I found this easy little fix, so I thought I should share it. First I made a backup of my primary drive with Carbon Copy Clone on an external drive. Then I restarted the computer, as it starts hold CommandS for just a moment until it starts to boot. At the prompt enter fsck -fy. Then let it do its ...

You can try the following programs to retrieve your data from lost/damaged partitions: FileSalvage, Data Rescue, Stellar Phoenix Mac Data Recovery, DiskWarrior. The good practice is to create an image of the actual partition and restore data from it.

The problem will lie with the dock disk-controllers and the method they use when translating the hard disk layout. I recently serviced an HP NX7400 laptop and the BIOS has two different modes for dealing hard disk translation - LBA Assist and Bit-shift. Both work, but if a drive is formatted using one method it will not be recognised if the other option is ...

Great post, it really worked and I'd buy you a beer for saving me from reinstalling Yosemite. Now I don't have to hear my wife complains about "System Disk Space is full". Took me a few days to find this answer but I'm glad I did. A few extra tips: While you are in "Recovery Mode" - also do a Repair Disk on the main OSX partition. I had a couple small ...

Disk1 is a "virtual device" which resides in disk0s2 (the Apple_CoreStorage Volume Group which actually contains a FileVault volume). You have only one 'physical device' indeed. Disk0s5 is probably an old Bootcamp installation. The clean way (get rid of the 2 Recovery HDs): Make a complete Time Machine backup of Macintosh HD. Start to Internet Recovery ...

OK, now i got my installation screen back How could i solve this problem? I just remove a blank NTFS partition (label as WINDOWS_HD) and leave it be a free space. That's all.

OS X Yosemite includes a recovery partition, the main one and a further one whose use i do not know but these are important so don't delete them. Sorry, you'll just have to work around it.

Boot holding Command ⌘ R at the chimes to boot into Recovery Mode, run Disk Utility & Repair Disk.

There is no need to delete the CoreStorage Logical Volume Group. Just resize it: Have a backup! Reboot into Internet Recovery Mode (hold Option-Command-R) as the machine is restarting). You'll eventually be presented with a Max OS X Utilities window. In the menu bar along the top of the screen, click Utilities -> Terminal. At the prompt, enter ...

Recovering a few files (or even most of them) in a backup does you no good. It's no longer a backup. I wouldn't even attempt to recover from this problem. Wipe the drive, let TM start backing up anew to it, and chalk this up as a lesson learned. It's easy to keep Time Machine itself backed up. Just start a TM backup on a different disk, and occasionally ...

Run the fstab command and remove all the setting there, then write the command. What I had there was preventing my Windows BootCamp partition from mounting. After removing it everything worked fine. http://www.cnet.com/how-to/prevent-a-partition-from-mounting-in-os-x/

In order to increase your Windows partition, you will need to first free up disk space on your Macintosh HD partition, as it appears to be full. 128GB isn't very much these days, I would recommend getting a larger hard drive, but transferring larger, less frequently used items such as movies or videos can often help free up large amount of space.

You should be able to delete the partition, and you would be able to re-use the space to create a new partition (of the same size). For some reason (not technical) OS X (lion or later) won't let you resize partitions on MBR disks. You could delete using gparted from a Linux live CD or many partitioning tools. You don't say what you are proposing to use the ...

If you use CarbonCopyCloner (after reformatting the SSD) it will give the option of moving across the Recovery Partition before moving your 500Gb of data to the new 1Tb partition.

The following diskutil cs resizeStack command is vastly undocumented and as such potentially destructive. Please backup your Mac OS X before proceeding. First you have to backup your Recovery HD: Start Terminal.app and enter defaults write com.apple.DiskUtility DUDebugMenuEnabled 1 press enter and quit Terminal.app Start Disk Utility and enable 'Show ...

The drive cloner did exactly what it was supposed to do – clone the drive, right down to the original volume's capacity. Try reformatting the SSD with one 1TB partition and then doing a standard Time Machine restore.

There is PARAGAN PARTITION MANAGER FREE EDITION with wich you can do this, to format in windows partitions to Apple HFS.

I had the same problem and I HAVE THE SOLUTION. The problem is that when you install Windows with bootcamp it is creating a Logic Volume Group. What you need to do is delete the Logical Volume Group. Very similar to if you have ever undone a manual fusion drive. Bust out terminal: diskutil coreStorage list Copy the Logical Volume Group ID diskutil ...

Try holding down the alt key while powering on your Mac. This should yield a boot device selection. If this doesn’t help, try booting in Recovery Mode as outlined here: http://support.apple.com/en-us/HT4718 There you can run Disk Utility to check wether your partition is corrupted.

That's an old bug in the BootCamp prefs. Just reboot and hold the alt key to get to the boot menu. Then choose your Mac OS X partition to boot into Mac OS X.

Try booting from a USB drive. Internet Recovery uses the local disk to temporarily store the image, which it won't let you delete. via

klanomath's answer is correct (and should probably be made an answer and not a comment) You already have three partitions on your computer: The EFI partition, the Mac recovery Partition and the main Mac filesystem (usually labeled Macintosh HD). Boot Camp will resize the Mac partition and create a Windows partition, that part is easy as the Boot Camp app ...

The Mac would only have a single partition devoted to OSX (actually there are also hidden partition). You cannot modify the partition while it is in use by OSX. You should restart in recovery mode, and you can then modify the partitions. I have never used Bootcamp, so @Buscar's suggestion may work, but it is easier to use diskutil to make a partition for ...

Fusion Drive technology is part of the Mac OS itself. Windows cannot use it. It can, of course see the Core Storage Drive & its NTFS partition & boot from it, but it cannot use the hybrid technology underlying 'Fusion' itself. Bootcamp will make the NTFS partition purely on the HD. btw, Bootcamp is the only way to add the extra partition to a ...
