Here I will assume you are using the BIOS/MBR legacy boot method for Windows. This means you are using a hybrid GPT. Idea 1: You could delete disk0s3 so you only have 4 partitions. I would first copy the contents disk0s3 to a flash drive. The application needed to do this can be found here. It works with Lion through Yosemite. I have not yet tested with ...

If you want better answers, try refining your question. Also, post a comment after my answer, so I will be notified. Question: 1) Recovery HD is visible, which, I could be mistaken, but this shouldn't be visible OR mounted in Disk Utility Answer: In the MBR partition table, the id should be AB and you have AF. In the GPT, the partition type should ...

I had experienced the same problem after resetting my Macbook Air and then attempting to re-install W7 in Bootcamp. The default bootcamp assistant download returns an error message, so I had to download an older version which did boot the W7 desktop, but without drivers for sound and wifi. I did however have USB functionality, from this I was able to insert ...

In your example, the command would be as shown below. ./install.sh --alldrivers --ownhfs /dev/disk0s5. I assume disk0s5 has been formatted "Mac OS Extended (Journaled)". I don't think I would use a 17.1 GB partition. The rEFInd partition on my Mac is 134 MB in size. If you need to write to disk0s5 while booted to Ubuntu, you may have to disable ...

I realize you have posted your own answer, but others may want to know what was wrong. Basically, you had journaling turned off. To turn journaling on, you need to highlight the partition and click on the "Enable Journaling" button. To see the change, you may have to quit and reopen the Disk Utility application. To turn journaling off, do the following ...

Since I'm trying to install Linux, I just booted from the Linux usb that I made, logged in with the "test linux" mode, then partitioned the disk using gpart.

It's indeed impossible to create a third regular partition in Disk Utility. The +-button is greyed out (please check the screenshot below): The superior HDD is my CoreStorage Volume Group, the inferior HDD is my CoreStorage Volume (spanning over disk1s2 and disk2s2) and HDD 2 is a simple JHFS+ non-CoreStorage volume. The complete volume list and the ...

It's not really wise to try repartition the disk you're booted from, so Disk Utility doesn't let you. You can boot from a USB key containing a recovery partition or a CD/DVD if your Mac is old enough to have a Superdrive.

The method to repair your disk and recover the GUID partition table is related to my answers to similar questions: HFS+ invalid number of allocation blocks and Hard drive no longer accessible. Basically you have to find characteristic strings of JHFS+ volumes, use some simple math and common sense and have some luck to fix the GUID. And don't loose sight of ...

You could try booting into internet recovery (hold Command+Option+R during boot) once there open disk utility and try partitioning again.

To free up space in your EFI partition, you would have to first mount it. This can be done using the command given below. Enter the command in a Terminal application windows. diskutil mount /dev/disk0s1 Below is an image of the entire contents of my EFI partition. I assume you can delete any folder and/or file other than what is shown below. (Actually, ...

I had the same problem. You just need to reformat it again even though it shows 100% empty, just click format.

You will likely have to install Windows 10 without the benefit of the BootCamp installer. Which means that you will have to create a bootable Windows 10 USB installer. If I recall correctly Microsoft will allow you to do exactly that with a Windows 10 download. Once that is created you should be able to boot the Mac from the Windows 10 installer and install ...

The simplest thing is to delete the "Data" partition and resize the Mac partition to take the whole area. At that point, you are one click away from running BootCamp Assistant. Options are to use Disk Utility to make an image of Data to an external drive (or perhaps to Macintosh HD if there is space). Another option is to clean as much files off Data or ...

This basically is a repost of the following sites: get "appleSSD.sys" error when installing windows 7 through bootcamp and bootcamp - appleSSD.sys digital signature can not be verified Looks like there are problems with Boot Camp Support Software (BCSS) being downloaded from Apple. Here is a solution: Download an older version of the BCSS for your Mac. ...

You cannot boot windows off a USB flash drive. You need a special type of flash drive then windows ultimate which comes with a USB bootable creation tool and a specialized USBkey. There are other methods with which to install USB bootable windows onto and I have tried them and they do not work.

I actually figured it out myself. All I had to do was turn off FileVault and restart the system. Disk Utility works normally now.

In Disk Utility, select the drive that you wish to partition, but select Repair in the bar with the options. Then, click Repair Disk Permissions in the bottom right. Repairing Disk Permissions isn't guaranteed to fix your problem, but it's a great start.

I think all you need to do is rename the drive using Disk Utility to MacIntosh HD. Then reinstall to it.


1

It doesn't look like you need to erase anything. Would you mind rebooting to Recovery HD and re-running Disk Utility to repair the drive? If that works, try again and see if you can get an error from Console or system.log if it fails you again. I'll dig into where BootCamp might log the failure in the mean time.

To interrupt the endless installation attempts you have to remove the temporary Yosemite installer folder and some invisible files in the root of your main volume. Boot to Recovery HD by pressing cmdR right after the start-up chime. Open Terminal from the menubar Utilities -> Terminal. cd to your main volume in the /Volumes folder with: cd ...

As a test, I formatted and external USB drive as exFAT (wrongly shown as ExFAT in Disk Utility) and then ascertained its UUID. Then ejected and unplugged the disk. I then added the following to my /etc/fstab file: UUID=402894E4-03EE-3CF7-80D2-A4EC74048C2F none exfat rw,noauto Note: Use the UUID assigned to the exFAT partition on your device. These ...

Just a point on scratch drives - SSD's are not recommended for scratch (virtual memory) in 2015 for two reasons (there may be more) - SSD's don't enjoy constant overwrite and data swappping and it will reduce the life of an expensive drive. Using a clean partition set aside on an internal Sata drive such as a WD Black (with 64MB on board cache) will be more ...

You most probably still have the disk partitioned in the GPT, but there are no partitions on the disk any more. This has happened to me twice when trying to remove the Boot Camp partition. You have to compare the output of diskutil list disk0 and sudo gpt show disk0 to see which partitions are still in the GPT, but are marked as unused. Then you'll have to ...

As the gpt command reveals you have two recovery partitions (and a lot of unallocated disk space after partition 4): partition 3 with a wrong size and a correct hexGUID (426F6F74-0000-11AA-AA11-00306543ECAC) partition 4 with a correct size (1269536 blocks) and a wrong hexGUID & visibility The second Recovery HD (slightly visible below the Macintosh ...

While you could technically use dd to image a smaller partition onto a larger partition and it still show using the space of the smaller partition you'll not be able to resize the NTFS partition using Disk Utility. Also the GPT and PMBR will not be synced and that will need to be resolved. Windows 7 will also need to be reactivated. That said, using ...

You have several options to clone the main volume of the MacBook Pro (early 2011) to the MacBook Pro 2015. Prerequisites: Update the MacBook Pro (early 2011) to the latest Yosemite version a Thunderbolt cable or an external hard drive and/or a full OS X on a thumb drive optional a backup/imager app like Carbon Copy Cloner Thunderbolt: Attach the ...

You can use Thunerbolt/FireWire to boot a Mac into Target-Mode to use it as a drive. Than you can clone it using disk utility, like you would clone a regular external drive. Next you'll (probably) need to reinstall OS X on the new MacBook Pro over that partition (so you have the latest OS X with all the drivers for the new device and whatnot), you can either ...

Take a look at Time Machine, it may be keeping local snapshots. From Apple Support: Because Time Machine removes local snapshots as needed, Finder and Get Info windows don't include them in their calculations. To see how much storage space local snapshots are using, choose About This Mac from the Apple menu, then click Storage. The space used by local ...

It was the Time Machine local backups. After running: sudo tmutil disablelocal I have my space back! The /Volumes/MobileBackups/ folder was enormous. I never use Time Machine aside from restoring from a catastrophic failure, and I don't know if I've ever touched the Time Machine GUI - so the local backups were completely unnecessary for me.

I can suggest you to try Disk Inventory X (http://www.derlien.com) It has a visual preview for the size of each file and different colors for groups of files/etc.

This post explains the procedure. Now is probably a good time to make a backup. Then proceed at your own risk...
