Re-sizing Macintosh HD 2 Partition

While trying to install OS X I had to partition my hard drive in to 2 disks, because the OS wouldn't install onto the first disk. So now I have it running fine on Macintosh HD 2, which is at 123.95GB, but I have 125.12GB of space on the first disk that I would like to rejoin with the second. I've looked on threads that say all I need to do is delete the free space partition and re-size the partition you want to keep. But since I want to keep my 2nd partion, I'm having trouble re-sizing it.
So in recap, I want to resize my 2nd partition to the full size of the hard drive. How can I do that?

Be very careful here. I attempted a resize similar to this and I nearly lost everything to a corrupted B-Tree.
Make a Time Machine backup before messing with this stuff.
You should be able to click around in Disk Utility until you find the page with information about your hard drive partitions. Select the Partition you wish to delete and press the minus icon just below.
Hopefully you get the prompt to remove and everything sounds good.
If this doesn't work, pray to whatever god you believe in that your hard drive still works. If your hard drive no longer works, you can hopefully reformat the drive and reinstall mac, then migrate stuff back from your Time Machine backup.

I had Partitioned my Macintosh HD, so now it has two, Macintosh HD and Macinyosh HD 2, but the question is, my computer has an minor update OS X 10.8.2 to 10.8.3, i wan to move all the files as BACKUP to the Macintosh HD 2, but how? Thanks.

As long as the Macintosh HD 2 partition is just the same size as Macintosh HD to avoid problems in the future, then you can clone one to the other using Carbon Copy Cloner, then use Disk Utility to Repair Permissions on both and if you need too you can hold the option key down while booting and select the #2 partition to boot from.
However you need to set CCC to maintain a pure clone, or else by default it will save the changes between clone updates and overfill your #2 partition.
Also the #2 is merely a bootable backup alternative and for retrieving the rarely occuring deleted files, don't use #2 for storage or anything you want to save pernamently.
In addition you also need external clones and backups, as the machine may fail or get lost etc.,

TS1600 OS X could not be installed on your computer. OSX can't be installed on the disk Macintosh HD because a recovery system can't be created.

I just bought the new OS X 10.8 and downloaded but when I tried to install it on my computer Installation Failed and I got this message:
"OS X can't be installed on the disk Macintosh HD , because a recovery system can't be created."
I tried so many times but the same message comes out to me each time and when I restart the computer I am back to the same OS X installer and can't access my computer any more so I am really stuck I can't install the new OS X version and can't go back to the old OS X version or access my computer.
Please help
My computer is MacBook Pro 13"

OK. You have a Boot Camp partition which is why the issue. See the following:
It seems the issue is that the space at the "bottom" of your available space when Lion installs it's partition is already occupied by BootCamp. The fix was to go into Disk Utility; Select your Hard Drive; Select Partition; Move the bottom of your main partition "up" a bit to create a space for Lion; close Disk Utility; Install Lion; once Lion is successfully installed, go back into Disk Partition and drag the bottom of your main partition back "down" to the bottom of the window.
In your case use Disk Utility to "shrink" your OS X partition a little more than 1 GB.
To resize the drive do the following:
1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired empty space. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.
Remember that you only need to shrink the OS X partition a little more than 1 GB. Now, when you try the Mountain Lion installation the installer will be able to make the Recovery HD.

Partition my ssd

Hello,

I would like to partition my SSD and FileVault is not enabled.
I completely format the drive and I have to partition before installing OSX, but now I'd like to change my diagram partion without deleting my data.
I open Disk Utility, and I click Macintosh HD => partition => I see the disk partion shcéma on the right side of the window, but the little "+" and the tab "patition scheme "are grayed out, I can not add other partitions.
Could you help me please, Thanks in advance.

It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.

How do I create a bootable Snow Leopard partition on my iMac running Lion?

Hi.
I have recently bought an iMac running Lion. I also have software such as Office 2004 and CS2 which I believe I can run using Rosetta, however I think I need Snow Leopard for this. If I purchase Snow Leopard from the Online Store, how do I install this 2nd OS within another partition on my iMac (yet to be created) and how do I switch between Snow Leopard and Lion on start up? Will my Lion software and data remain intact as I don't have any Lion disks should I need to reload this? Can anyone help with a step-by-step instructions as I'm not incredibly confident with the repartitioning of my nice new iMac?

I recently upgraded from Snow Leopard to Lion and now some CDs I use for school do not work. Can I create a partition to run both Snow Leopard and LIon or does it only work to run windows? How do I do this?

Getting a new CD from publisher is not an option as they would want me to pay for a new one and they are pricey. If possible I would prefer to keep my upgrade to lion but would go back to leopard if there's no other option.

You can add another partition on which you can install Snow Leopard. If you do, however, you cannot use Boot Camp Assistant to install Windows. Just so you know.

Can I partition an external drive into MSDO and MACOS extended and use under bootcamp ?

I am interested in using Windows 8 alongside my OSX MAVERICK with the Bootcamp 5 solution.
However, I am trying to save the space on my internal SSD . Can I partition my 4TB WD external drive into 3 parts like this :
1.5 TB dedicated for Time Machine in MAC OS Extended Format
1,5 TB MAC for general purpose in MAC OS Extended Format
1.0 TB Windows for my PC games and other stuff in exFAT for files larger than 4GB
Is this possible at all or what would be better ?
Thanks

Disk Utility won't partition my drive.

I have a LaCie external hard drive with a capacity of 298 GB and 247 GB used leaving 51 GB free. I am trying to create a 30 GB partition of just free space, but when I tell Disk Utility to start, it will start working for a while saying "Modifying partition map" and have the blue and white barber-shop pole for the loading bar. After a couple of minutes, Disk Utility will popup with and error saying there isn't enough room on the drive. Can someone explain this to me?

How do I create a Snow Leopard partition?

I just upgraded to Lion, and unfortunately, can't access my Quicken 2007. (Didn't realize Quicken didn't work in Lion until after I downloaded it. Clearly, I live in a barrel.) I just downloaded iBank and need to export my Quicken data to it. From what I understand, I need to create a Snow Leopard partition where I can export my info.
My question is, how do I do this? Although I know a lot about a lot of things, this isn't one of my areas of expertise, so please be gentle and walk me through it.
Thanks SO very much!

Adding a new partition in free space wipes all others?

geez, I hate writing a question when I think I've already found the answer!!
But in this case, the answer's so baad, I thought I'd run it by you all before I hit "desperation" mode! Here goes...
I've got a USB 1TB external that I back up on to. It's in 4 partitions (audio, video, system, archives). The 4 partions are using about 750 Gb total, with 250 Gb free. I wanted to resize the "system" partition, as it was getting pretty full. I found some instructions about; (1.) creating a new, fifth, empty partition out of that 250Gb free space then (2.) "merging" the new partition and the system partition, resulting in a single larger partion for system backups. All other partitions *should* have been left untouched.
I was a bit wary of it all, but Disk Utility's Help says, "You may be able to create multiple partitions on your disk without losing any data" and then goes on to tell me how to, using the + sign, create a new partition out of the 250Gb of free space.
I followed the instructions to the letter but, after "Applying", it did create the new fifth partition, *BUT IT WIPED ALL OF THE DATA OFF OF THE OTHER FOUR PARTITIONS!!*
I'm in major panic mode, did a bit of searching and, on Indiana Univ. help page, found:
"Warning: ...when changing the partition scheme in Mac OS X 10.5 and later, partitioning your hard drive with Disk Utility erases all the information on the drive."
As I see it, a direct conflict to what Apple claims in Disk Utility's Help.
So, I'm about to pull out and upgrade my data recovery programs - - will just try and get the pix and tunes back, I guess.
But if anyone has any idea how I can "undo" what's been done, it sure would help!!
many thanks in advance,
b myers

I'm not sure what you did exactly, but having done it you cannot undo it. You may yet be able to recover files from the drive using recovery software:
Basics of File Recovery
Files in Trash
If you simply put files in the Trash you can restore them by opening the Trash (left-click on the Trash icon) and drag the files from the Trash to your Desktop or other desired location. OS X also provides a short-cut to undo the last item moved to the Trash -press COMMAND-Z.
If you empty the Trash the files are gone. If a program does an immediate delete rather than moving files to the Trash, then the files are gone. Recovery is possible but you must not allow any additional writes to the hard drive - shut it down. When files are deleted only the directory entries, not the files themselves, is modified. The space occupied by the files has been returned to the system as available for storage, but the files are still on the drive. Writing to the drive will then eventually overwrite the space once occupied by the deleted files in which case the files are lost permanently. Also if you save a file over an existing file of the same name, then the old file is overwritten and cannot be recovered.
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.
For future reference:
To resize the drive do the following:
1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.
2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.

Recovery partition missing after Time Machine restore of Lion

I recently purchased a new hard drive for my macbook pro and restored my system to the new disc via a Time Machine backup of the old disc. Everything worked fine and my mac is running faster than ever thanks to the new drive
I just recently realized, however, that by using this method of restoration, the Lion recovery partition that was created during my first install is gone. This is probably due to it being a hidden partition that disc utility on my install disc was unable to recreate.
I verified that the partition is missing by downloading the new recovery tool that Apple released a few days ago. It failed to work because the partiton could not be found.
My question is if anyone else has realized this issue and if there is a solution. Is it possible to recreate the partition without going through an archive-and-reinstall routine? In my opinion this is a bit of a blunder by Apple as it renders Time Machine usless.
Thoughts? Suggestions?

Read the instructions for using the Recovery HD installation tool. You must make a small partition on the new hard drive of about 1 GB or so on which to install the Recovery HD.
To resize the drive do the following:
1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.
2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.

Partitioning Lion and Snow Leopard

I've tried following the instructions other people have posted about this to no avail. I'm on a 17" MacBook Pro with 2.8 GHz Intel Core 2 Duo. The only reason I bought Lion was to run Avid MC6. It's rubbish, so I want to reinstall Snow Leopard and run both. Tried to partition my drive, but I keep getting this message: "Partition failed with the error: Couldn’t modify partition map because file system verification failed." Did repairs in first aid without success. Any ideas?

Have you tried partitioning your drive from the Recovery HD?
Try rebooting into the Recovery HD by pressing COMMAND and R together at the startup chime. Go into Disk Utilities and try adding a 2nd partition. If all works, you should have your Macintosh HD and a Macintosh HD 2 partition that you can use to install SL onto.

Upgraded my macbook pro to mountain lion. But during windows installation, it refuses coz of FAT file system. Also is it possible to partition after windows installation???

I just upgraded my macbook pro to mountain lion. Now I want to install windows, but during installation using bootcamp, it says windows can't install on FAT partition. I couldn't change it to NTFS. Also how can I partition my hard disk after windows installation. Coz before windows installation, if I partition hard disk, it won't allow me to install windows saying startup disk can't be partitioned.......help would be appreciated.
Thanks

Yosemite does not allow a new installation of XP, but an existing XP installation is self-contained and will continue to work. Does your XP installation use a FAT partition? You may be better off using NTFS and then upgrading to Yosemite.
Will the Yosemite upgrade process delete my Windows XP partition or crash my current BootCamp? Can I still have an option to load OS X or Windows XP (press 'alt/option' key during boot up) after upgraded to Yosemite?
If you have made any re-sizing attempts to WXP partition Yosemite will cause problems, otherwise the Yosemite upgrade leaves XP untouched.
Are there any specific reasons to upgrade to Yosemite?

Hello shah129,
You’re having a problem running a recovery from the recovery partition. When you upgraded to windows 8 you disabled that partition.
In order to go back to Windows 7 you will have to order the recovery media from hp.com.
