I acidently created a second partition on my HD, how do i delete it?

i dont want to reimage

OK, then. Here's what you can do.
1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list. This should be the drive you want to re-partition.
2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. Click on the partition you want to remove. It will become outlined in blue.
3. Click on the [-] button below the sizing window to delete the partition.
4. In the lower right corner of the sizing rectangle for the remaining partition is a resizing gadget. Select it with the mouse and drag it down to fill up the space left by the deleted partition. Click on the Apply button and wait until the process has completed.

I have a 15" MacBook Pro with Mountain Lion installed. I have partitioned the hard drive into two partitions. Is it possible to install Snow Leopard on the second partition? If so how do I do it?

If your MacBook Pro had Snow Leopard on it at one time then sure. (Early 2011 or earlier)
How to erase and install Snow Leopard 10.6
Obviously choose the second partition to install into. It has to be OS X Extended journaled formatted in Disk Utility (BootCamp software makes it a MSDOS/FAT32 formatted partition if you used that to partition with)
If it's a Early 2011 or Late 2011 that came with 10.7, it's possible, but it's not easy.

Geotagging - how can I edit new places that I have previously created but with typos, errors etc? How do I delete a place I have set up?

Geotagging - how can I edit new places that I have previously created but with typos, errors etc? How do I delete a place I have set up? Then I could create a new, correct entry. I'm using iPhoto '09.

Is it OK to reply to my own question?? Thanks to the related posts that appeared AFTER I'd made the post above, I learnt about the 'Manage my places' item under the Windows menu. I felt a bit dumb not knowing this.
BUT it doesn't completely resolve the issue. The info shown in the EXIF (using opt-cmd-I) under Places has the place name I choose, but it is followed by a few other lines that are incorrect and do not seem to be anything to do with any data I can see under 'Manage my places'.
Can anyone explain where these other entries might come from, and how to edit them?

How to create a second partition on the harddisk?

Hello To All Members!
I recently got some viruses on my laptop. So I had to use my recovery cd to recover my system.
Now the problem is that I asked me for the partition where are the files which are being extracted. I marked it to 30GB.
So, windows is working fine but my Rest of 50GB will not be shown.
I thought that the recovery cd will make a new second partition as well, but it did not. Now how to make some other partitions?
Second question related to first one is how much time i can use this recovery disk. I mean will the windows remain genuine?????
For the partition problem i dont know of some possible solutions cause i needed three partitions, 1st of 30GB(Windows Default) and other two of 25GB.
The Best Solution coming in my mind is to make any windows ME or 98 bootable cd and run fdisk to create the remaining partitions.
But it is makes some new questions in my mind. Do i have to use a recovery cd again? If yes than I will not use this process again cause it will ask for partition to extract files of windows and i will choose 30GB again.
And again it will remove additional partitions.
Please help me and clear the questions coming in my mind..

Hi there,
do know for the UlltimateBootCD4Win? This from CD bootable WinXP-BartPEedition with additional tools gives you the ability to make such things like partitioning, backup or formatting your HDD.
It has many more applications which help you to maintain your system without booting your original OS.
So I think that this CD will solve your partitioning issues.
Heres a link: www.ubcd4win.com/
Just try it and tell me your opinion.
Nice weekend and greetings from the sunny south ;)

Tecra A8-104: How to create a second partition on HDD

Hello.
i had to use the recovery disk, and i deleted by mistake my initial (two) partitions of the HDD. :(( now i have only one.
Can somebody tell me how can i fix that?
I want 2 partitions not one. 10x

Hello
If operating system is already preinstalled and configured you can now use third part software to split HDD and create second partition. The best tool for doing this is Partition Magic.
If you want to install OS again using delivered recovery DVD there you can find option for doing this. Start notebook and press C button. Keep it down for few seconds. This will force your notebook to use CD/DVD driver as first boot device. Simply follow the menu on the screen.

Creating second partition stuck

I have tried to create a second partition on my WD Mybook 1tb, I set up disk utility to create a small 10gb partition and set it to work, during the 'shrinking disk' process it seems to have stopped and doesnt seem to have progressed for about an hour, I guess it is not save to quit Disk Utility is there anything I can do?
Thanks

Try looking at the drive in Disk Utility and insure that it shows the correct partition table (GUID) in the status area below the window.
No it isn't 'safe' but I think you are going to need to quit DU and then restart and repair the drive if possible.
My tip: don't modify a drive you don't have a backup for.

Help Creating a Windows Partition

Hi I've got 2 hard drives. I want OS X Leopard on Bay 1 and Windows Vista on Bay 2. In Boot Camp Assistant which Bay do I select? Do I select "Create a second Partition for Windows" or "Erase disk and create a single partition for Windows"? any help is greatly appreciated

Your support person you spoke with wasn't thinking multi drive, only the single internal hard drive configuration.
Boot Camp Assistant will actually ONLY use the entire drive. So some people put a small OS X partition on it to force it in two.
I would play around, practice. But if you get familiar - can't hurt and always only helps - Disk Utility => Partition tab => Options.... (bottom of screen) and change it from default "GUID" to Windows Boot Record. Create MSDOS (FAT32).
Vista will install just fine, and gives you the option to format / delete and create - but if it is on its own drive it usually complains about "GPT" due to the presence of OS X drive. That is easier to do than describe / explain. There is an Apple and MS tech note though.
I like the OS to be on the outer tracks, higher performance. The idea of putting an OS on the 'backend' where I/O is the slowest is just.... sluggishly slow and I'd never want or put OS X there for regular use.
Also, once you have Vista, it is a lot easier to install a 2nd system, like "7" on another drive or partition; rather than boot and run from DVD, copy DVD easily to disk and it is lightning fast. Down the road.
You should be able to just boot from Vista even without doing anything, just remove OS X, treat it like a PC, and install. Works best if the drive is raw and was never formatted in OS X even.

Partition layout greyed out – not possible to create a third partition

Hi all,
Being in need of a new laptop, I bought myself a Macbook Pro retina, 13inch, 512gb SSD last weekend. I’ve been a windows user for almost 20 years now, with occasional exploits into Unix/Linux, but I’ve had it in mind to try out OS X for quite a while. I like the hardware and the design of the Macbook Pro and the fact that Boot camp promised to make dual booting into win7 a walk in the park, lead me to just try it out. However…
When I tried running boot camp (based on creating bootable USB’s):
ISO number 1 first didn’t get recognized by boot camp
Omitting the bootable USB creation by boot camp, downloading the drivers on a separate USB stick and using my own bootable USB lead boot camp to state that it didn’t recognize a windows install disk (even though the USB is bootable and does work)
Creating a full new ISO and using that one to create a bootable USB by boot camp worked, but gave an error during the copying of the files (can’t create USB, error during copying windows installation files)
Making a new image of that ISO within OS X to avoid compatibility issues gave the same error
Using another USB stick gave the same error
Unmounting the image still gave the same error
At that point I gave up on wanting to use boot camp and I decided to do the install myself. Going to disk utility to create new partitions triggered a new issue:
Via the “+”-sign, I can create a second partition on my drive. I can name that partition, format it any way I want and make it as big as I want.
After doing that, the “-“-sign is available to remove that partition again and to merge all back into one big HFS partition.
The tool doesn’t allow me to create 3 partitions though. The partition layout box is greyed out and fixed on “current”, and after the second partition is created, I can create a third one
Rebooting and doing disk utility via CMD+R gives the same issue.
I looked on the internet, found people with similar issues, but until now no real solution (unless a “boot via USB and partition from there”-solution, which I didn’t try yet).
Why doesn’t the system allow me to create 3 partitions?
What can I do to still create 3 partitions?
Is working via a bootable OS X USB really the only way to do this?

Boot older version of mac as a second partition

Hi I'm running OS X Yosemite on my mac currently and want to make a partition so that I can boot OS X Lion. I have the InstallESD.dmg file and a 4.7GB re-writtable DVD that I've burnt it to and I have created the second partition ready for the operating system to be loaded onto. As far as I can tell, I just need to hold Alt while the mac restarts for me to select the DVD as the startup disk for the installation to start. When I click on the disk however, it just boots into the regular Yosemite startup disk. I want to install Lion from the disk I've created onto my second partition.
Any ideas?
Many thanks,
Dan

It won't boot from the DVD. What you need to do is put it on an 8 GB USB flash drive properly partitioned and formatted for OS X.
Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
Use DiskMaker X to put your installer clone onto the USB flash drive. Wait for the process to complete which will take quite some time.

Boot from second partition on usb hard drive

I have a time machine external usb drive. I have created a second partition of 8GB on this drive and restored OS X Install ESD 10.7.5 to this second partition so that I can easily rebuild if necessary. I would like to be able to boot from this second partition. When I hold down Option key at startup, I see the external drive as an option, but the iMac wants to boot from the Time Machine Backup partition, rather than the Lion Partition. It doesn't give me the choice of the second, bootable partition on this drive. Is it possible to do this?
[Mac 24" early 2009, running 10.7.5 Lion]

rchealey wrote:
Curiously when you boot from this partition, you get virtually the exact same experience as you do when booting from the recovery partition except that the recovery partition tends to suggest that it will download and install Lion, whereas booting from the partition containing the install doesn't mention download.
That's normal behavior. The Recovery HD only has enough code to go to Apple's servers and DL the installer; whereas, the InstallESD contains everything. Do note, however, that running either will check Apple's servers for additional components, whatever those might be. Thus, Internet access is required to do either.

Create Boot camp partition on multiple partitions disk without reformatting

Hi everybody,
I am trying to install Windows 7 on a multiple partitions 1TB disk.
Currently I have 2 partitons:
300GB - OS X Lion
700GB - Data
I have read some tips and advices on how to install windows on multiple partitons disks - most of them are invasive (backing up to a removable drive and then reformatting). However, I haven’t found conclusive answer (hence my posting here):
I’m wondering does anybody know in any way - is it possible to do this more painlelssly - to divide second partition (or maybe first) and use that one as a bootcamp target?
Or am I stuck with reformatting to a single partition and then installing from scratch?
Thank you.

No. To use Boot Camp Assistant your drive must start with a single volume encompassing the entire drive - one partition. BCA will then create a second partition for Windows and modify the bootloader so you can select which volume to use for startup - OS X or Windows. BCA can also remove the Windows volume and restore the drive to its original state - single OS X partition.
If you have more than one partition already then BCA cannot modify it. If you have a drive configured with BCA and subsequently add a third partition then BCA is no longer able to manage the drive, and you may no longer be able to boot Windows because of changes made to the bootloader.
So, yes, you are stuck with "reformatting to a single partition and then installing from scratch."
Your alternative is to create however many partitions you want. Install Windows on one of them. Download rEFIt to replace the standard bootloader so you can select between Windows and OS X (or any other OSes you install.)

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 help

Good 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 do I delete a partition that was created in Bootcamp?

I installed XP on my MBP using Bootcamp a while ago, and recently erased all the data on the partitioned drive. I have the second partition doing nothing and would just rather delete it.
I have been told that I need to use Bootcamp to delete the partition, but everytime I load bootcamp it says:
The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.
I cant even get into bootcamp, what should I do? Do I need to do something in Disk Utility?
Thanks in advance.
Chris

Yeah I find using the Boot Camp utility is much easier. Open Applications and find the Utilities folder and open that. Then find and open the utility called "Boot Camp Assistant". It will walk you through the process of restoring the drive to a single partition -- it's real easy.

How do I delete primary partition?

So yesterday, I decided to try mountain lion by creating a second partition and doing a clean install onto the second partition. Since I've decided to keep only mountain lion, what would be the best way for me to delete my primary lion partition?
I've read about using CCC or Superduper, but was wondering if there are any other easier alternatives like deleting the primary partition and keeping the 2nd partition with ML on it.
Thanks.

You need CCC. It's very easy to use.
Boot from your 2nd partition, download and install CCC and then use it to clone the 2nd into the 1st. CCC will also take care of creating the recovery partition on your 1st partition, which is very important (just follow the instructions when prompted).
Once CCC is done cloning, boot from your 1st and if everything is OK, you may erase the 2nd if you want to.
