Deleting partitions

Is sit possible to delete partitions and leave data intact?
Or must I back up each partition and then erase the HDD and restire data.
One partition is my boot partition (Lion 10.7.3) , another is uTunes , a third is data and the last is Snow Leopard.
In total almost a TB.
Computer is an iMac 24unch, (2006 model), shortly to be replaced by a 27 inch iMac current model

Deleting a partition will erase the data on it. In addition, the Disk Utility can't change the starting point of an existing partition.

Recovery on a Satellite A100 (PSAA9) - Deleted partitions and XP Home not Pro

We recently had trouble with our laptop and decided to restore it back to manufacturer settings with the recovery Media CD. My son decided to do it and when he booted up the program he chose the Delete partitions option instead of overwrite.
Now it has completely formatted the HD removing the OS (Windows XP Pro).
When I bought the laptop it came with WXP Pro already installed and just has the Certification Sticker on the bottom of the laptop.
Is there anyway that I can receive a Windows XP Pro installation CD?

Generally all Satellite notebook models are delivered with WXP Home or Media Center Edition operating system. Toshiba has Satellite Pro series and under this name you can get WXP Pro operating system.
Can you tell us which model you have exactly A100-xxx?
If your notebook was in showroom by the dealer it is possible they have used own OS installation instead of delivered recovery media.

I can't delete partition in disk utility, it keeps telling me that "the changes are too small"

I previously split my disk into two different disks, however I want to combine them together again, yet i was unable to delete the second partition. I can't delete partition in disk utility, it keeps telling me that "the changes are too small"
Plz help!!!!!!

Make at least two complete backups of all your data. Boot from another drive and partition this one as desired. Restore the data.

What is the best way to restore very recently deleted partition ?, What is the best way to restore very recently deleted partition ?

Can anyone please advise the best course of action here:
I time machined what I thought to be my Mac Pro 1,1 but actually backed up my Macbook Pro 3,1
I was having problems with main hdd and repair was not working so i deleted partition... and when i ran time machine realised i had not backed up from march.
Is there anyway to revert to that partitioning or restore it? Any programs?
Or do I just have to recover the lost files ?

If the lost data is of high value to you, consider sending the drive to a professional recovery service such as DriveSavers. Otherwise, there's little hope, but some have had at least partial success with a product called "Data Rescue."

How to recover files from a deleted partition?

Unfortunately, my OSX was not booting and I deleted my partition. Through the Internet Recovery mode I reinstalled the original OSX Mountain Lion it came with. I then upgraded to Maverick. I know that deleting a partition practically means all files are lost. I heard that files can be recovered on a Windows when a partition is deleted. Is there any way I can recover files from a partition that was deleted just a day ago?

Hi,
Yes, it is possible to recover deleted partition or volume on Mac. Previously I was able to recover all my data lost due to accidental deletion of partition on my Mac PC by using recover Mac data software. This tool is really helpful, here you can download this tool.

Time Machine can't keep history of deleted partitions

I didn't realize, as I deleted my "Data" partition that I would also lose all TimeMachine history for that partition.
Maybe it sort of makes sense if you know how the internals work, but when I run TimeMachine now, I can't see the now deleted partition. So trying to access some data from a few days ago... I'm out of luck.
Have I missed something and there is actually some clever way to access data that was on a deleted partition?

Recovering deleted partitions in Windows Server 2008 R2 Server Core

I was expanding one of my drive (Drive A) partitions to use space available on another drive (Drive B) and then I wanted to delete the extension so I clicked on the second drive (Drive B) and deleted that partition. What I didn't realize is that
would delete the entire partition on Drive A. Now that I have screwed up I desperately need to recover the partition. I ran the free tool TestDisk (http://www.cgsecurity.org/wiki/TestDisk) but it did not see the deleted partition. Can someone
point me in the right direction for recovering the partition and or data?

Well I was able to fully recover the deleted partion and restore the Hyper-V VM's and figured I would share the steps I took to recover.
Deleted Partition Recovery
Do not reboot the machine because the MBR will be commited permanately.
Use a partition recover tool (I used Active@ partition recovery) to recover the
deleted partion.
Restore the MBR which should be the backup MBR at this point (not 100% sure on
this).
If you did reboot and you cannot restore the MBR then you may have to backup the
files from the deleted partition and recreate the partition manually. This was the case for me.
Use a file reovery tool (I used Active@ File Recovery) to backup the deleted
files.
Recreate the Partition manually and restore from the backup.
Hyper-V Virtual HardDisk Restore
Restore the .VHD and .AVHD from the backups.
Because you restored from backup the ACL (Access Control List) entries will be
wiped and you will have to remove the hard drives from the virtual machine and reattach them. Re-attaching the .VHD will recreate the appropriate ACL entries. Worst case scenario you will have to recreate the VM and attach the hard drive.
Remove the Virtual Hard Drive from the Virtual machine via Hyper-V Manager.
If there are Snapshot files you must first merge them back into the main .VHD
Change the extension of the most recent .AVHD to .VHD.
From Hyper-V Manager select Edit Disk and browse to the newly renamed Snapshot
and use the Merge option to merge it with its parent disk. The merge wizard will automatically select the appropriate parent to merge with. Take a note of this name because you will have to repeat the process on this file. In Hyper-V Versions
prior to 2008 R2 you may have to manually select the parent, in this case you will need to figure it out yourself but fortuanately you can sort by date and go from latest to oldest in order.
Repeat the above process with each successive Snapshot until you have merged with
the main .VHD for the VM.
Reattach the .VHD file which will restore the Hyper-V ACL entries.
Start the VM.
If you get the following error when logging in to the VM “The trust relationship
between the primary domain and the trusted domain failed.” You will need to remove the machine from the domain and readd it to the domain via the local administrator account.

You also can't delete the system partition, boot partition, or any partition that contains the virtual memory paging file, because Windows
needs this information to start correctly. For more information, see Can
I repartition my hard disk?

Bootcamp no longer bootable after adding and deleting partitions

I am using a 2014 Macbook Pro with OSX 10.9.5
I was trying to add a partition to install Ubuntu on and after adding and deleting partitions, my bootcamp partition will no longer boot whether I use rEFIt or bootcamp assistant or normal osx boot menu.
Judging from the information I got from similar threads on this I think this information will be useful

It wasnt like this before. Before 3 and 4 had some of the same values from above instead of all 0s. After trying to take advice from threads with similar problems and entering stuff into the command line it became like this. I think I might have messed thing up while looking for a quick fix.
Can anyone help me with this? Thanks.

I'm not sure how to edit my replies so I'm just gonna make another reply. I assumed the following values:
GPT 3 Start
GPT 3 End
GPT 3 Size
NTFS Start
NTFS Offset
NTFS End
NTFS Size
293378384

I followed the rest of the instructions given here. I made sure to enter the second number with a + sign. After doing all of that all these checks worked:
Test 1 - Does Bootcamp Volume show up in Finder?
Test 2 - Can you see files in Bootcamp Volume?
Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk?
I've always been able to access my bootcamp files from finder and I can try to boot from System Preferences -> startup disk, from rEFIt and also from my macbooks startup manager that I access by holding down option while booting.
I'm starting to think I've misrepresented my problem and that I've been looking at the wrong threads. Every time I try to boot windows I get a black screen with the Windows logo and some text saying something like "starting automatic recovery" or something like that. It then takes me to a blue screen displaying an error number and telling me to use recovery tools on the installation media. Maybe this is different from the problems I've been looking at in other threads.
I've tried using the same USB I used to install bootcamp with but it doesn't give me the option of repairing the installation.
EDIT: So I figured out how to edit replies. Anyway I just tried to boot into Windows and checked. The black screen with the Windows logo says "Preparing Automatic Repair". The blue screen gives me the error 0xc00000e.

Bootcamp will no longer boot after deleting partition #3 of my new Mac Mini. What happened? Was it the way I tried to reclaim the HDD space for Mac?

Here's my dilemma. I have a new Mac Mini - a week old. I installed Windows 7 on it using Mac's Bootcamp assistant. I then set up and configured my Windows 7 world and everything worked fine. No issues logging in between Lion or Win7 via the restart/option key procedure. Well, yesterday I split my Mac HD partition one more time to create a third partition (was created as an "extra", e.g. possible future partition for another operating system). After creating it, I then decided that I didn't really need it. So I deleted it in Disk Utility and attempted to drag the Mac HD partition line downward so as to "fill in the gap" and reclaim the lost hardrive space. It seemed as if I could reclaim about 1 gig or so, but I figured...oh well.
Well, the Mac HD partition seems to work just fine, but now I've noticed that I can't get into the Bootcamp partition anymore. It wont boot. If I try to verify the partition [doesn't even give me "repair" as an option), then it fails and gives me the following error message: "verify volume failed. invalid request." When I go to the Startup Disk option in my System Preferences section, it displays the bootcamp partition as a folder and not as a drive anymore.
I'm assuming that I messed up some permissions or lost some vital links during my attempted resizing/reclaiming of harddrive space. How do I fix this without having to reload either all of my Mac info or all or my Win7 info? I'd hate to consider the last two days of my life loading this crap up a complete loss.
Thanks in advance!

Thanks for checking in, BDAQua.
Problem solved.
In the docs that came with my Powerlogix accelerator card, I found this sentence buried:
"If you reset the PRAM, the NVRAM code for OS9 compatibility is cleared, so you will have to boot from the Firmawre Update CD and perform this process again in order to boot in OS9."
The "process" it's referring to is the process of setting up the NVRAM for booting into OS9 from the CD.
Fortunately, I was able to find the disk, and it worked as expected. I can now, once again boot into OS9.
Conclusion: My (unadvised) attempt to load Leopard on this old machine apparently reset the PRAM on the accelerator card and cleared the NVRAM code for OS9 boot. Although I did attempt to reset the NVRAM via Open Firmware, it did not reset it on the accelerator card.
So, thank you BDAQua, for your "Ah yes" . . . that's all I needed to steer me in the right direction.
Gratefully,
tupester

I cannot recover accidentally deleted partition.

When I tried to install windows 7 through the boot camp assistant, I accidentally deleted a partition of 200gb. I think it was #1. How can I recover it in os x 10.9? The OS X 10.9 shows 200gb less the total hard-drive space. Thanks.

If the photots weren't backed up, there's no way to recover them.

Bootcamp Utility Error When Trying to Delete Partition

My hard drive is almost full and I need to delete my 50 GB Windows partitions. When I try to do it using Bootcamp Utility I get an error message. Not sure how relevant this is, but I upgraded to Yosemite a few months ago. Any suggestions?

Please check whether clearing the Contribute preferences helps you.
To Clear the preference, quit Contribute, and then delete the Contribute CS5 folder in C:\Documents and Settings\<user>\Local Settings\Application Data\Adobe\ and also run the following command " reg delete "HKCU\Software\Adobe\Contribute 6 " /f " if you are using Contribute CS5. Reconnect to the site and try the same scenario.
Note that, if you clear the preferences then no connection will be listed in Contribute, you need to recreate the connections. It will be like a fresh installation.

Deleting partition not working

Running 10.5.6. On a macbook pro 17". Having managed to fill up my main hd and trying to free up some space.
I'm trying to delete a 32gb partition I made and no longer have the use for.
I went into disk utility and erased the partition. Then went to the partition section of the main volume to press the minus button to get rid of it but when I did that I got a message that said..
"Partition failed with the error: Could not unmount disk"
So returning to that partition I right-click it and choose to mount the disk. Which i then told me "The disk "disk0s3" could not be mounted. Try running First Aid on the disk and then retry mounting."
(disk0s3 is the name of the partition)
Ok ok.. so i go to run first aid... The only option I have here is verify disk.
The things I see in red..
"Volume Bit Map needs minor repair.
Invalid Volume file count.
Volume header needs minor repair
The volume disk0s3 needs to be repaired
Error: Filesystem verify or repair failed"
Ok.. so.. i don't want to alter my larger volume I simply want to delete the smaller one. Any suggestions or means of getting this done? or what step I should take next? Run to the apple store and say "fix it!"

Welcome to Apple Discussions!
You need to boot from your install disc and navigate to Disk Utility on the install disc. Then select the 32 GB partition and see if you can repair it. Repair it until there is nothing left to repair. Maybe once it's repaired, you will be able to delete it.
Good luck.
