Can't create Macintosh HD partition - greyed out
I was erasing the data on a mid 2012 MacBook Air before giving it away and I think I deleted the Macintosh HD partition (The second one from the top in disk utility that is indented over.)
Once this happened I lost the OS X and was not able to get past OS X Utilities when turning it on.
I tried doing the Reinstall OS X but my entire hard drive (128gb) was not there to select, only the recovery HD (approximately 600mb.)
I was able to download OS X onto a flash drive and that lets me get into the MacBook, however I still cannot access the hard drive.
When I go back into Disk Utility the option to create a partition and access the entire 120gb is greyed out.
I don't care about saving/recovering any information, I just want it back to normal.
If anyone can help me out it would be greatly appreciated, thank you!
Do this:
Install OS X Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

How can I create a new partition to install Windows 7 by not using Bootcamp
How can I create a new partition to install Windows 7 by not using Bootcamp?
If you want to dualboot you have to use boot camp i think. I think you have already a full disc and cannot make another partition I'm I right?
Your question seems a bit blurry so I'm giving you a general tip here.
If you want to just try the beta you can always use Sun's "Virtualbox". -

Windows 7 setup can't create or see partition
Hi all, I am trying to install Windows 7 x64 SP1 on my late 13 MBP. I used BC assistant to mount the iso on a 8gb usb. I have used two different iso files, one from digital river and one from torrents (its not a 'cracked' one or anything, I just couldn't find how to get one from Microsoft. This one is supposedly the same as the one from microsoft.) I plan to get a license key from my university once I make sure I can install it. Anyway, I can mount the iso and download bootcamp files using the assistant. I can make the partition using BC assistant as well, and I set aside 32gb for the Windows partition. After it partitions, it reboots into the Windows setup.
In windows setup, I pick windows 7 professional 64-bit from the list, hit next until I get to the part where you select the partition (of the four) on which to install Windows. When I select the BOOTCAMP one, there is the same little dialog text at the bottom as if I had selected a mac partition, saying that it can't install and the partition must be formatted or something. So I select the BOOTCAMP partition and press Format. When I press Next, a message appears saying that "Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information."
I have also tried: unplugging all USB peripherals
using the right instead of left USB port
not formatting the drive and pressing 'next' only
deleting the bpptcamp partition from within windows setup and then forming a new partition and then formatting that
using both ISO images
selecting each of the four editions I can choose from (home, home premium, pro, and ultimate)
repairing/verifying the mac HD and permissions
Note that every time I re-attempt, I am forced to remove the windows partition and recreate the partition using BC assistant. In other words, if I quit windows setup and restart, hold down option, and select the windows USB to boot, a different windows setup starts up. It is similar but has slightly different screens than before, and after I press "install now" (a button absent from the first setup) an error message pops up saying that a CD/DVD driver is missing and I must locate it. When I try to locate the driver, which I would think would be in the bootcamp folder on the USB, it can't find the USB! Under My Computer all I see are the C: drive (inaccessible from here) and X:, which I think is the windows partition because it has some of the windows system files on it. I can't get past this stage of looking for a driver without completely removing the partition and then rebuilding the windows partition using BC assistant.
What do I do?
If it helps, in the mac os disk utility I can look at the Info for the windows partition, and in the properties it says "Owners Enabled: No, Can be Formatted: No, Bootable: No". Does that matter?
Thank you!I don't have a hub, I will try a usb 2.0 though when I get a chance. Diskutil list gives:
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *251.0 GB disk0

Hi,
I want to create a new partition as I have done before a few times.
Now, the problem is, that I get an error message, when I'm trying to create one.
Unfortunetally the error message is in German, so I try to translate it:
"Partitioning failed
During partitioning is occurred an error:
MediaKit reports: System has for the desired process not enough memory"
You can see the screenshot under following link:
http://www.apfeltalk.de/forum/partitionen-zusammenf-hren-t174556.html
The point is: I have 2 GB RAM and more than 100 GB on my harddisc free!
Probably this problem occured with Mac OS X 10.5.5.
Does anybody know an solution?
How can I contact Apple to inform them about this problem and get some help?!
Best regards
StefanoYour translation is probably a little off and rather than meaning there's not enough RAM it means there's not enough contiguous hard drive space to make a partition of that size. I'm assuming that you are trying to partition a drive that already has data on it. If I am right, before the drive can be partitioned, it has to be defragmented so that the drive has no data in a group of tracks equal to the size you requested. It is possible to request a partition size that looks like it should fit but there's one or more files that cannot be moved out to make space for it. That, is what I think has happened to you.
If I am right you can try defragging your hard drive with a program dedicated to defragmenting and optimizing. Some people have had success doing this and others have used such a program and still couldn't partition their drive. You can clone the drive to another hard drive (SuperDuper! and CarbonCopyCloner are two good cloning programs) and then turn around and clone right back to original. This will work because as the files are copied to the target drive they will all be placed in contiguous sectors so the drive will be completely defragmented. Or you can try making a smaller partition. -
Can't create a 3rd partition in Disk Utility
Long story short I have used Boot Camp to get Windows, so I have 2 partitions. But, I need to create another partition to install another copy of Windows on it, but Disk Utility has grayed out the '+' to allow me to create a new partition. All I can do is delete the 'BOOTCAMP' partition which I don't want to do. I tried another way by going into Boot Camp Assistant and installing Windows through there. I have a bootable USB drive and I know how to install it, all that's stopping me is the partition issue.
Any ideas?
If it helps, I'm using a Late 2013 MacBook Pro with a 15" Retina Display, 2.5 GHz, 512 GB SSD, 16 GB RAM and a NVIDIA GT 750 M.
Thank you for your helpGood thing to mention that, I forgot to do that.
Unfortunately it did not help.. The screen to remove the existing Boot Camp partition does not pop up, it just tries to create the new Boot Camp partition.
The partition I'm trying to create it 150GB. The 50GB mentioned above was on the stock Fujitsu 250GB disk.
Edit:
I'm actually trying to avoid using Boot Camp Assistant.. I became to dislike the utility due to problems creating a partition on my previous HD.
I would like to create a partition using Disk Utility and then install Windows 7 by selecting that DVD to boot from.
Thank you for the tip though, I'll post it there as well! -
How can I create a recovery partition to use Find my Mac?
I want to activate Find my Mac on my MBP. The iCloud system preference says I don't have a recovery partition that's required for it. It apparently didn't install when I upgraded to Mountain Lion.
How can I retroactively create a recovery partition? There are no other partitions on the drive (other than the Macintosh HD, of course).
Thanks.
RobFIRST, assuming you do not have another Mac of the same model with a working restore, I would suggest using your Lion, mountaint lion or Maverick install to create a bootable system on a flash drive. You will need a DMG image created with Disk Utility from that stick to recreate the restore partition on your mac.
Once you create the bootable USB stick, Use it to log in and follow the below process to back up the restore partition. Then, save the DMG back up anywhere and finish the walk through on your normal operating partition.
Close Disk Utility if it is open.
Open Terminal
Enter the command below
defaults write com.apple.DiskUtility DUDebugMenuEnabled -bool true
Now open Disk Utility and pull down the Debug menu
Click Show Every Partition
Now, select the Recovery Partition and create a new image.
NOTE: The Recovery Partition will need to be made in Read Only format if you wish to restore the image normally with disk utility or by software such as Deploy Studio. If you take an image with Deploy Studio and want it to restore the Recovery Drive normally, you will need to adjust the Work Flow for Image Capture to use the Read Only format. It will slow things down. If you dont use the read only format, the .dmg will not scan properly. This is most likely because the recovery drive already hosts compressed files. That said, this guide WILL restore from even a compressed .dmg image. HERE IS THE WALK THROUGH FOR RESTORING A SCANNED READ ONLY FORMATTED .DMG.
Copy the Recover HD.DMG image to a flash drive
The following must be on an Administrator account
Next, Log on to the admin account of the computer you wish to restore the MLTI Recovery Partition.
Copy the Recovery HD.DMG from your Flash drive to the HD
Enter the following command in terminal
diskutil list
If there is no partition for the restore drive listed, then use Disk Utility to create a GUID Partition keeping in mind the size of the original restore partition. (19 gigs for the MLTI Version of the restore drive)
Open Terminal and enter the following command
sudo asr -noverify -source (PATH FOR DMG IMAGE HERE) -target (PATH FOR RECOVERY HD PARTITION HERE) -erase -noprompt
NOTES: You must replace the () and everything in between with the respective path. You can simple drag and drop the source (your .dmg) and your target (the drive to be restored) while you are typing in terminal.
Enter admin password
In terminal Type the following command
diskutil list
note which disk and slice is the restore partition. It should be /dev/disk0s3, but it could vary a bit.
Now, run the following in terminal
sudo asr adjust --target /dev/disk0s3 --settype "Apple_Boot"
REMEMBER: you may need to replace /dev/disk0s3 with your new restore partition's designation.
Enter Admin Password when prompted
Restart.
Don't forget to enter the following terminal command into the machine you took the Recovery HD image from.
defaults write com.apple.DiskUtility DUDebugMenuEnabled -bool false -
Can i create a disk partition and install SL onto it from my disks I got with my iMac
I want to start learning how to use the Terminal and how to start inputting and outputting data via the Terminal. I thought that I could create a small partition on my hard drive and then install Snow Leopard onto that partition (so that while I was learning how to use Terminal commands I would not wreck anything.)
It then occurred to me that by doing this I would also learn how to install OS X.
Can I do this?
Does the disks I got with my iMac have a limited number of installs? Because if they do I don't want to use them up in case I have to reinstall at any point in the future.
Do those disks have a full version of OS X Snow Leopard on them, or are they just for repairing the version on my system?
If I was to create a partition, when I delete that partition will I automatically get back the space?
Is what I want to do hard?
Can someone please give me some guidance before I begin doing this?
Many thanks
JasonThe OS X Install Disc that came with your computer is just that a full licensed copy of OS X for your system, it can be installed as many times as you would like but it will ONLY work on your machine. The only limitation to those discs that I'm aware of is they are machine specific.
My suggestion would be to get an external HD and use the Install Disc to install OS X on the external. Don't get a cheap USB drive, get the fastest drive (at the moment that would be Firewire 800) you can get. Drives I'd recommend are Lacie Quadra d2 series, G-Tech G-Series and OWC (www.macsales.com) Mercury Elite Pro series. This would be a much wiser strategy than partitioning your internal drive, that way if you real create a major mess it won't affect your internal HD.

Can I create a Bootcamp partition without installing Windows immediately?
I have a clone of my bootcamp that contains Windows 7, but can't restore to the Clone without a Bootcamp partition.
I am running Lion.
Is there anyway to create the bootcamp partition without the Windows Install Disk?...if so, I could just restore my Cloned Bootcamp onto the Bootcamp Parition.
Thank you,
AKWait...after I hit send, I realized you had cloned your boot camp parition with winclone. My bad...well, you can always try putting the cloned partition on the exFAT partition, if possible. I think what I had to do when I bought a new hard drive was to boot into the old had drive. I then attached the new drive with a handy universal drive kit (http://eshop.macsales.com/item/NewerTech/U3NVSPATA/). I think I used iPartition to create an NTFS partition on my new drive. I then copied my cloned Windows partition onto the new drive.

Boot Camp can't create a Windows partition
Hello,
I'm trying to create a new partition to install Windows 7 on, but I am unable to do so.
At first I tried to do this with Boot Camp Assistant, but it didn't work.
Then I tried to create a FAT partition with Disk Utility, which didn't work either.
So I verified and repaired the disk, tried to create the partition again, yet it still didn't work.
I verified and repaired the disk and tried to create the partition while running the OS, in Safe Mode and from the Mac OSX Install DVD.
Neither of them worked.
I noticed while running the OS, the info of the HD said the capacity is 749.81 GB, while checking that from the Mac OSX Install DVD it only says about 700 GB (I mentioned 698.6 GB).
Strange..
It might also be important to mention that I recently (2 days ago) I installed a new HD: Western Digital Scorpio Black 750 GB, and today I swapped my 2x 2GB RAM for 2x 4GB RAM (Samsung).
On my previous HD, the Fujitsu 250GB, this proces was no problem at all. I installed W7 on that drive just a week ago.
I made a clone of the Fujitsu HD and "back-upped" it to my new WD HD. The W7 partition on the Fujitsu HD was 50GB, which is the difference in capacity mentioned above. I'm not sure if there's a link here..
I've got a MacBook Pro from mid 2009.
I'm not sure what to do next... I'm stuck!
Any help is greatly appreciated!Did you do an upgrade to Leopard? If so, some files may be scattered over your HD, making it impossible for BC to find a single contiguous area on the drive.
Also, be sure you did not have eDisk installed - that's the thing from the TechTools disk that comes with AppleCare.
This is not an uncommon problem. It's not just you.
If you have a complete backup of Leopard, you can use the DU to make a single partition. You may be lucky and not lose any data, but backup anwyay.
In DU, repair the disk, if necessary and verify/repair permissions.
Once you have done this try again.
If BC still fails, you will need to erase the HD and then copy everything back from the backup.
I always suggest a bootable clone for the backup and be sure to test it first to see it works. -
Can't create a windows partition
I'm trying to create a windows partition through bootcamp but it refuses to do so because I'm guessing that it's scanning permission that need to be repaired. The message states that I need to run disk utility.
The problem though is, I can't do anything about the permissions cause of a known "bug" (??) on leopard.
It states 3-4 permission need repairing but they can't be repaired. Others have that issue but they probably had windows installed before this happening.
here is an image of disk utility.
http://idisk.mac.com/dkatsafouros/Public/permissions.jpgAlright I solved the problem. It was a repair disk and a repair permissions check.
Everything is fine now -

But the table could hold at most a single record (per client). The design is lacking.

How can I create Fade-in or Fade-out on Click of Button?
I'm using Encore DVD 2.0. My DVD starts with a video on a timeline, and then jumps to a main menu with a motion background and music. The main menu links to a couple videos on timelines.
I'd like to do 2 things:
1) When the user clicks a button on the main menu to bring them to a video on a timeline, I'd like the main menu itself to fade out before jumping to the timeline. How can I make this happen in Encore? I of course can't create this fade-out in the editing of the video, since the user could possibly click the button at any point throughout the video.
2) In transitioning from the initial timeline to the main menu, I would like the main menu to fade in. Is this possible, and if so, how can I make this happen in Encore?
Thank you for your help.> I'm trying to understand what you mean. Did you mean that I can make my entire menu part of the background motion video? How would the buttons work? Is there a way to create invisible buttons in Encore?
Sorry for the confusion - I didn't write that as clearly as I should have done.
Right now, in Encore, you
i cannot
use "Buttons Over Video" as it is not in the feature set. What I was trying to say is that a feature request might get this functionality added in a later build. We can but hope, anyway.
What I can recommend you try is using After Effects or Premiere Pro to create your Motion Menu, and set things up so that the appearance of the actual buttons is delayed to the point you want them to appear at.
Another solution - this will give you minimal delays (should be very close to seamless on the final DVD) is this:
1 - Intro to Main Menu.
Create your intro to the main menu, and set this not as a timeline, but as a motion menu. Set the End Action of this to go straight to a static/still copy of the final frame from the Motion Intro.
2 - Main Menu
This will be a still menu, with or without Audio. If you use Audio it will need to loop though.
3 - Outro from Main Menu to timeline.
Fake this as follows.
Method A.
Create the outro to the timeline and set this as another motion menu - not a timeline - with it's end action set to automatically play the main film. The outro will presumably fade to black, so any transition will be un-noticeable.
Method B
Fake the outro by adding it to the start of the main timeline.
I think Method A will be your best bet here.
