Losing disk partition after choosing startup disk
Hi,
I'm using MB Pro retina 2012, I have 3 disk partitions. 1 for Mac osx, 1 for windows (bothcamp) and 1 for data (ExFAT). I using it normally until I change startup disk to Windows. After that, data drive is not show anymore. I have more than 100GB important data on this drive. What happend? How to restore them? I cant repair disk, it doesnt work for me. It show like this on disk utility.
I've tried to mount it, repair, verify but not successful. This is the log:

Thanks for help
You CAN'T have 3 partitions on your Mac and have the Windows install work. Windows only allows 4 Primary partitions on any one physical hard drive. Since you created a exFAT partition you have past that Windows limit.
One partition for OS X, one for Windows, one for the OS X Recovery HD and the forth for the EFI. Now that you have created a so called Data partition windows will no longer boot.
You are basically TOAST and might need to start over with a total wipe, Re-Partitioning, of the drive then reinstall OS X and you programs and files then reinstall Windows program and files and then do not try fooling with the partitions again, any of them on the OS X or Windows side, because if you do Windows again will not boot.

Hi!
I am getting the error:
"The startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted as a single Mac OS Extended (Jounraled) volume or already partitioned by Boot Camp Assistant for installing Windows."
I read up some on google, but all of them says that they have crated a partition and that is the problem, I only have the standard "Macintosh HD".
I tried to create a partition manually in disk utility but then the error message: "Partition failed with error message: Could not unmount disk."
Can anyone help me? It's driving me crazy.
Thanks.This message, and threads like yours got asked daily for over two years, now it is only a couple times a week!!
Is it so hard to follow through? you were to have backup already, clones are best, then erase/format and restore.
Then partition.
Some have been able to use Disk Utility booted from OS X DVD or another drive, and repair the drive.
You have to use Boot Camp Assistant (99.9% anyway) to create and achieve a proper Windows Master Boot Record partition. -
Can't resize disk partitions after Yosemite install.
My disk has two partitions. I run Mavericks on the first, and recently installed Yosemite on the second. The OS works fine, but I no way to resize the partitions. I've tried booting into both Yosemite and Mavericks but the partition layout in disk utility appears locked with fixed partition sizes.
It now appears that I have two options.
Use the undocumented "resizeVolume" command in diskutil to resize the core storage volume in my Yosemite partition, or
Use the "revert" command in diskutil to revert from core storage to the default partition type and try my luck.
Is anyone else facing this issue of not being able to resize your disk partitions after the Yosemite install, and if so, how did you resolve this?
Thanks in advance.None of these worked. I had to resolve this the hard way.
Make a complete TM backup of the new Yosemite installation.
Use a bootable install DVD or USB drive, re-partition the disk and do a complete reinstall.
Recover the applications and data from the TM backup.
It took me about an hour and a half once I decided on this approach, not counting the hours wasted trying to get it working.
To give them credit, the TM backup and restore worked flawlessly and all my apps and data were back without a hitch.
However, reading the other posts in the forum and elsewhere it does appear that Apple has not done a good job with the disk utility in supporting core storage volumes, which is fairly ridiculous since Yosemite defaults to that without giving you a choice. -

If you have Apple Care, call them and get a case number. Otherwise, take the computer to an Apple store or an AASP. Whichever is more convenient for you.

I know there's a bunch of procedures for starting up in different modes, I just can't find them on the Apple Support pages. (I know, I'm supposed to know them) Right now I want to start up on the mode where you choose the startup disk. There's others too, like starting in safe mode. I'd like to see a list of them. Like choosing startup disk, do I hold down the 's' (for startup) or the 'd' key (for disk), or maybe the 's' key is for safe mode. Thanx, sorry to ask such a nooby question.
Hi Ken Spiker;
If your Mac is shut down and you are starting it then holding down the option key will reveal the system disks.
If you are running open System Preference > Startup disk will reveal the system disks also.

Key combination to choose startup disk
My Windows partition is hosed. How do I get back to a screen that lets me choose my start-up disk? I can't remember the key or key combination.
Thank you,
NancyResetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
>>Turn on the computer.
>>>Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. If issues persist, your Mac's logic board battery (not a portable Mac's rechargeable battery) may need to be replaced.

Unable to choose startup disk with "Option" key
I recently ran into this problem after installing Windows through Boot Camp. When I boot up my Mac and hold the "Option" key it just ignores it completely and flies right on into whatever OS I have selected as my startup disk.
It also will not work if I have a DVD or CD in the drive, and I noticed it is doing this even without a Windows partition.
Any ideas or help is appreciated.
Thanks in advance,
AaronAs I said above, it works fine.
I noticed this as well: none of the keys on the keyboard work when the machine starts up. I tried plugging the keyboard directly into the Mac instead of having, at I usually do, plugged into the Cinema Display and that didn't change anything.
I recently just took the machine in for repair and the replaced an I/O board, any chance that may have something to do with it? It was working fine before I had the repairs. -
IMac G3 freezing after changing startup disk?
Hello.
I bought a iMac G3 I few months ago just for a hobby and have been playing around on it.
This morning I noticed two other previous system folders in the system folder.
I then opened "startup disk" (I think that is the name) and chose to restart with "Previous system folder".
When it re-booted it opened up differently, had a new background and made sound effects when clicking and scrolling.
I decided to change the startup disc to "Previous system folder1" (which is the other previous system folder)
This time when restarting it booted normally until the desktop icons loaded. The mouse and keyboard froze and then a message popped up saying "To use your internal modem you need to select the country from where you will be using your computer". I try to use the mouse and keyboard to select, "Australia" and then "OK" but as previously started the mouse and keyboard are frozen.
When booting up I can use the mouse and keyboard on the loading screen until it freezes when the desktop appears.
(The computer was working amazingly before I stupidly changed the system folder)
Why is this happening. How do I return to a previous system folder when it keeps freezing.
Here is a youtube video showing you what happens:
https://www.youtube.com/watch?v=uYURgG2W5x4
Please note, I do have all the software CD that came with computer, however for some reason discs won't work on the computer they are unrecognizable.
All keyboard commands do nothing for example holding down shift into safe mode still freezes.
Thanks in advance!
StewartI'm not sure what OS you are running here.
There is a way to set what os boots from the firmware. Not sure how. Look tomorrow. let me know via another post.
For classic, you could try hold the
space bar
then booting. or is it the shift key?
If this is a slot loader, try:
The startup manager will list all of your bootable partitions then give you a choice of which to boot. Hold down the option key then power on. Continue holding down the option key until you see the startup manager. This brings up the startup manager. Click on your hd or disc. Click on right arrow key.

Startup keys
http://macs.about.com/od/macoperatingsystems/qt/osxstartupkeys.htm
I have a list of magical boot key sequences:
Key Combinations-- Effect
* mouse down -- Eject removable media ( I think Boot ROMs prior to 2.4f1 excluded the CD drive )
* opt -- Bring up OF system picker on New World machines.
iMac g3 400 or newer machine
* cmd-opt -- Hold down until 2nd chime, will boot into Mac OS 9 ?
* cmd-x (or just x?) -- Will boot into Mac OS X if 9 and X are on the same partition and that's the partition you're booting from.
* cmd-opt-shift-delete -- Bypass startup drive and boot from external (or CD). This actually forces the system to NOT load the driver for the default volume, which has the side effect mentioned above. For SCSI devices it searches from highest ID to lowest for a partition with a bootable system. Not sure about IDE drives.
* cmd-opt-shift-delete-# -- Boot from a specific SCSI ID # (# = SCSI ID number)
* cmd-opt-p-r -- Zap PRAM. Hold down until second chime.
* cmd-opt-n-v -- Clear NV RAM. Similar to reset-all in Open Firmware.
* cmd-opt-o-f -- Boot into open firmware
* cmd-opt-t-v -- Force Quadra AV machines to use TV as a monitor
* cmd-opt-x-o -- Boot from ROM (Mac Classic only)
* cmd-opt-a-v -- Force an AV monitor to be recognized as one
* c -- Boot from CD. If set to boot to X and no CD is present, may boot to 9.
* d -- Force the internal hard disk to be the startup device
* n -- Hold down until Mac logo, will attempt to boot from network server (using BOOTP or TFTP)
* r -- Force PowerBooks to reset the screen
* t -- Put FireWire machine into FireWire Target Disk mode
* z -- Attempt to boot using the devalias zip from first bootable partition found
* shift -- (Classic only) Disable Extensions
* shift -- (OS X, 10.1.3 and later) Disables login items. Also disables non-essential kernel extensions (safe boot mode)
* cmd -- (Classic only) Boot with Virtual Memory off
* space -- (Classic only) Trigger extension manager at boot-up
* cmd-v -- (OS X only) show console messages during boot
* cmd-s -- (OS X only) boot into single user mode
Did not work simply 'z'?
You could buy an external DVD drive. It needs to be firewire and bootable by Mac OS. If you have another PPC with firewire, you could try target Disk mode and installed tiger that way.
You need to figure out the level of your firmware before installing 10.2 or greater. ( The PC name for firmware is BIOS. ) Installing 10.2 with a down level firmware will most likely make your iMac unusable and difficult to fix.
What is Open Firmware?
The firmware on a PPC is called Open Firmware. Open Firmware software receives control when you poweron your machine. It does some hardware testing and some hardware configuration then passes control to your version of Mac OS. It reside on a PROM ( program read only memory ) chip on the logic board.
Figuring out what level of Open Firmware you have?
1) Mac OS 9.x or 8.x, you need to use the Apple System Profiler.
Apple -> Apple System Profiler
2) Mac OS X, use the System Profiler.
Apple -> About This Mac
click on the More Info... tab
click on Hardware
read the Boot ROM Version
3) Open Firmware, boot into Open Firmware.
Power on your iMac while holding down command+option+o+f
The first output line contains the firmware level. Mine reads:
Apple PowerMac4,1 4.1.9f1 BootRom built on 09/14/01 at 13.18.04
Copyright 1994-2001 Apple Computer Inc.
On my machine, I have 4.1.9f1.
What firmware do you need?
http://support.apple.com/kb/HT1395
You can download the firmware from this page:
http://support.apple.com/kb/DL1283
filename: N-iMac_FWUpdate_4.1.9.smi.bin
avoid expanding the file on the download computer.
For a slot loading iMac, this article indicates that you need to be running 9.1 or later version of Mac OS Classic.
http://support.apple.com/kb/DL1283
"The iMac Firmware Update 4.1.9 will only run on iMac computers with slot-loading CD or DVD drives running Mac OS 9.1 or later from a local drive. If you are using Mac OS X you must boot from a local Mac OS 9.1 or later writeable partition (not a CD, or network disk) prior to following the update instructions."
You can download the Mac OS 9 updates from the Apple site.

For tiger, you need 256meg of memory. A slot loader will take 1gig of memory.
You may need to get more memory.

Can't write to external disk after cloning startup disk to it
After cloning my PowerBook Pro's startup disk to an external Thunderbolt drive, and temporarily using that drive to boot-up, the Thunderbolt drive is locked into Read Only mode. How do I enable it to write again? The INFO pane says the following: System privilege: "Read & Write"; wheel: "Read Only"; everyone: "Read Only". The basis for my cloning was to deal with a very full startup disk that I did a lot of video editing on (very processor intensive). The disk had become fragmented to the point that it couldn't access sectors fast enough for editing, so I cloned it over to a G-Tech Thunderbolt drive (using Carbon Copy Cloner), reformatted the MacBook startup disk, then reverse-cloned the copied files back over from the Thunderbolt, the idea being that they'd be re-written nice 'n neat in unfragmented order into their proper sectors. I then ceased booting-up from Thunderbolt, but now the system seems to think that Thunderbolt is still special in some way like a gossling bonded to a surrogate human mother, and it won't let me write to it. Can anybody help me with this?
Have you verified and if necessary, repaired the disk(s) using Disk Utility on your Mac?

Allow all users to choose startup disk
Is there any way to allow all users to choose the startup disk on the OS X side? We want non admin users to be able to reboot to windows without having to hold down the option button when booting.
There are two methods for what you want to do.
1. Remotely - Boot Camp: Set the startup disk remotely from a server
2. Locally - How to choose a startup disk on your Mac - Apple Support -
Difference between choosing startup disk at boot, or via System Preferences
Not a technical problem exactly, just a straighforward question: when I choose a startup disk in System Preferences or in the Windows Boot Camp Utility, where is this preference stored?
I have noticed that using either of these utlities is the only way to make the disk choice persistent; booting while holding down the Alt/Option key only allows you to temporarily select a startup disk.Only difference is when you use the Startup disk applet in System Preferences the system will auto boot to that OS. When using the Option key boot system no matter which OS you select the next time you Reboot the system will boot back to the one that was selected from the Startup Disk selection.
So if you are auto booting into OS X and then reboot and use the Option key to get the Boot selection screen and select Windows (or another version of OS X) the system will boot to that selected OS. But when you do a Shut down or Restart the system will then boot back into OS X. The Option Key boot selection screen is only for that one startup.
Same thing go for if you are auto rebooting or auto starting up in Windows and use use the option key to boot into OS X. Then next time the system is restarted, Restart or shut down and then turned back on, it will Auto boot into Windows.
The Startup Disk option tells the EFI firmware which OS to Auto Boot To. The Option key is a ONE Time Boot option. -
Time machine no longer backs up after cloning startup disk
I cloned my startup disk (250 mb) in April 2013 to a 500 mb disk and replaced it with the cloned disk. Before the clone, Time Machine was backing up properly to the 6tb external drive designated for backup. Since installing the clone Time Machine has not backed up anything. Everything (all the apps) is working properly on the cloned disk except, apparently, Time Machine. In fact, I cannot get Time Machine to allow me to make any adjustments to the settings. I went on the Apple Support website to see if I can reinstall Time Machine, but could not find anything. Any suggestions?

Not able to resize and make a partition of my startup disk
Hi, I'm running Lion on a late - 2010 15 inch MBP and I already have a Boot Camp partition of Windows 7. I wanted to partition my hard drive again to install Ubuntu (which should be relatively painless). I tried out the live CD to get a taste of what it would be like, and actually tried partitioning from there, which did not work. So I booted back to OSX and went to Disk Utility, selected my drive and tried to resize my Macintosh HD partition to make space for a 4ish GB partition for Ubuntu. I hit Apply, but then I get this error:
Partition failed with the error:
File system resize support required, such as HFS+ with Journaling enabled.
My Macintosh HD is of type Mac OS Extended (Journaled), and my Bootcamp is NTFS. I see EFI and Recovery HD partitions that I haven't seen before, but I understand they have always been there but were hidden.
I tried repairing disk permissions, and it works for the Macintosh HD, but when I try for the entire drive I get this error, even though I clearly have an EFI system partition that I can see:
This disk doesn’t contain an EFI system partition. If you want to start up your computer with this disk or include it in a RAID set, back up your data and partition this disk.
I ran diskutil disk in Terminal and this is what I get. Looks alright to me:
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *320.1 GB disk0
1: Apple_HFS EFI 209.7 MB disk0s1
2: Apple_HFS Macintosh HD 285.1 GB disk0s2
3: Apple_HFS Recovery HD 650.0 MB disk0s3
4: Microsoft Basic Data BOOTCAMP 29.1 GB disk0s4
5: EFI 209.7 MB disk0s5
So what do I do so I can partition my disk successfully? I'm willing to backup and erase my harddrive completely to install Lion again, but I recently did that (well, a few months ago) when I felt that updating from Snow Leopard without a clean install was laggy. So I hope there's a way I can do this without doing a clean install again.
Thanks a lot, and this is my first question so I hope I've provided enough info.I am experiencing the same problem and was interested in how this was resolved?

Problems with Snow Leopard and choosing startup disk.
I just installed Snow Leopard 10.6.3 on my external drive to test it out. Most things seem to work just fine, but I'm having problems selecting a start up disk from system preferences. When I bring up start up disk, I see the internal and external drives but they are greyed out and unselectable. How do I get back to starting up off of my internal drive? Is this a common problem?
Do try CT's suggestion first; that might be the most likely explanation.
In Disk Utility in Applications>Utilities, do you see both drives?
You might be able to get back into the Internal by starting up from Startup Manager. Hold the Option (Alt) key down at the startup chime. When that finishes loading, you should be presented with icons for both drives. If that succeeds, and you can return to the Internal, you can then see if the options in Startup Disk are available.
In Disk Utility, I would also repair the External, if and when you are booted back from the Internal.
And once you are booted back normally, highlight the mounted External Volume and do a Get info (CMD-I). Make sure "Ignore Permissions on this Volume" is unchecked.
Edit: as CT suggested, you should also repair Permissions, but -- and this may have changed in 10.6, not sure -- you should generally repair Permissions booted from the Volume you are repairing. Before repairing Permissions, however, on any Volume, you should first Verify that Volume. Repairing Permissions on a Volume with problems will only make those problems worse.
