Problems restoring partition after bootcamp failure

Hi!
I'm using a new MacBook Pro (Retina, 15") with OS X 10.10.2 where I tried to install Windows 8.1 with the help of the Bootcamp-assistant. Everything went well to set up the partitions and I decided to set aside 50 GB for my Windows partition. But the Windows 8.1 installer for some reason refused to install on this partition so without thinking too much (big mistake) I tried formatting it from within the installer which didn't work and lead to boot problems when I restarted. Without knowing so much about these things I understand that the Windows partition manager where writing in places on the disk that wasn't so good for the OS X system? Anyway, I have managed to get back to booting normally and within the Disk Utility in OS X I deleted all the different small partitions (that I could see) and the 50 GB Windows partition so that there is now just the main OS X partition showing and 50 GB of unused, unpartitioned space.
An this is where I'm stuck. Everything works fine except I now have a 50 GB smaller disk... I wan't to restore everything back to having just one big OS X partition but I can't use the Bootcamp-assistant since it does not recognize the disk as being managed by it and from inside Disk Utility I can't resize the OS X partition back to normal. I can't pull the slider to increase its size, I can't manually type in the partitions size since those numbers are greyed out and I can't create a new 50 GB partition of any kind since when I try to proceed nothing happens. I have even attempted to format the whole drive and restore my time machine backup from recovery mode but I can't figure out how to do that. I seem to be able to format the, now smaller, OS X-partition but doesn't that just create a new partition with the same size? How do I erase everything and create a completely new partition with the maximum size? Oh, and I also tried removing the OS X-partiton by pressing the minus button at the bottom but that button is greyed out as well. Even in recovery mode...
I have included two screen dumps. Sorry for them being in Swedish... Hopefully they can be of help anyway.
Thank you in advance for any help!!

This problem is being discussed in Is there a way I can get the "Free Space" back without completely restoring my hard drive?

How Do I Add Partitions After Bootcamp Installation?

I want to have Windows 7 on my late 2013 Macbook Pro 13 to run applications not available on OSX. I need a small separate partition to store files for one of the applications that runs under Windows. On my older PC Windows machine I have C:\ that contains 98% of the data and a separate partition that acts as a separate drive (M:\) to store library files. This is a local copy of a server that I carry on my MBP, and doing this as I've done keeps the configuration files (that point to the server M:\) on my MBP consistent with desktop machines that actually point to a network shared drive (M:\). I just sync my small partition with the server every so often to keep my MBP functioning when I'm disconnected from the server. Now the problem. I can install Windows via bootcamp and that creates a C:\ (Windows partition) and gets Windows up and running. I have already learned the hard way about adjusting the partitions after bootcamp installation (I've rebuilt my Mac about 3 times ). I have been able to create the correct number of partitions by running the bootcamp assistant, creating the bootcamp partition, rebooting and <option> booting back to OSX, before installing Windows to add this 10GB partition (as FAT32) for my "M drive". Now after creating the "M drive" partition, I booted back into the Windows install disk (which has issues with USB drivers not functioning which I got past) and now I find out Windows will not install because it can't format the bootcamp partition since it will be a 5th primary partition and Windows 7 only supports 4 primary partitions on a drive. Is there a better way (without virtual OSs)?

Not possible. Boot Camp only works for two partitions - the OS X one and the Windows one. That's it. If you attempt to put a third partition on the drive, then Boot Camp is no longer able to manage the drive and you will lose the required boot loader for Windows. Getting things back to normal will then require repartitioning the drive back to one volume and reinstalling OS X from scratch.

Unable to Adjust Partition after BootCamp

Hi
I use Boot Camp Assistant (BCA) to remove Windows 7 and ended with a message "Your disk could not be restored to a single partition". I am not sure if the Windows 7 is successfully removed.
I use Disk Utility (DU) to try to "re-partition" the Mac HD to 250GB (from 218GB) but after checking catalog file and other processes, it ended with a message "Could't modify partition map because the file system verification failed"
I use the First Aid to verify disk and reported the partition map appears to be ok
I use the Repair Disk and it reported the partition map appears to be ok
Below is the map of the partition after I remove the Windows 7. I dragged the white color region (botton right) to extend to 250GB and click Apply and failed with the error message "Could't modify partition map because the file system verification failed"

So just clone the volume and then erase and restore.
If you created Windows with BCA and you didn't do anything else in Windows or Mac OS to add change or shrink etc BCA should have.
In some cases that error happens when creating or attempting to create Windows partition not on removal.
Paragon CampTune is handy but for what you want just use Carbon Copy Cloner.
I always advise using a dedicated drive just for Windows.
You will find more on Boot Camp forum.

Can't restore to 1 partition after bootcamp

Ok so I ran into a weird problem, and after searching for a while I can't seem to find a solution.
Can't find anyone else who has had the same problem either.
I'm currently running a 2012 RMBP. I had bootcamp installed running Windows 7.
Today I wanted to remove the Bootcamp partition to free up some space on my HD.
So I went to Bootcamp Utility and selected the option to restore Mac to 1 partition and remove bootcamp
After a while it gives me an error message, something like "cannot remove bootcamp partition or restore mac to single partition"
Ok...
But not the bootcamp partition is gone from the bootcamp utility. It's also gone from Disk utility and the Finder.
But the space that the partition was occupying (about 20+ gigs) did not change.
So it's like it's still there but I cannot erase it or get that space back for some reason.
I've tried everything. I tried rebooting using CMD+R and going to disk utilities from there also. But the bootcamp partition
doesn't show up at all. But the space it was taking is still there.
Also in Disk Utility I cannot "erase free space", it's greyed out. I can't do anything. It's like the bootcamp partition is gone, but
the space is still being taken up. So it was never really removed.
I don't know what else to do. Any ideas? Has this happened to anyone else?

I encountered the same, or very similar problem with my 2012 15" rMBP. Upon trying to uninstall Windows 7 and its associated 60GB Partition via Boot Camp Assistant (BCA), some sort of error (dialog disappeared too quickly to recall specifics) apparently prevented completetion. During my second attempt, the process appeared to stall at about 25-30% completion. After the "progress bar" hadn't moved for 10 minutes, I quit BCA.
My third attempt ended at the second BCA screen, as the initial three options (for installing Windows) were again available. I thought perhaps I had actually erased the Windows Partition, but Disk Utility still displayed an unnamed 60GB Partition. Unfortunately, resizing my boot volume to 768GB triggered a file system verification error, as did Mende1's thoughtful solution.
Finally, after highlighting my SSD (not my boot volume Partition) and selecting "Verify Disk", the "Repair disk in Recovery Mode" error suspended Verification. After rebooting in Recovery Mode (command + R after chime), repairing the drive in Disk Utility did just that, and I was able to simply resize my boot volume Partition, removing the empty partition. I guess BCA had uninstalled Windows 7, but failed to remove the partition.
Sorry for the longwinded post, but since the OP's solution didn't work for me, I thought I would share the process that worked for me.

Problem with partition after deleting a bootcamp partition

Hi everyone !
First, excuse my english, I'm from France.
This morning, I've deleted the bootcamp partition I had created weeks ago. But when I've tried to extend the principal partition on the empty space left by bootcamp, the Disk Utilitaire says : "Partition failed : impossible to modify the partition map because the verification of the files system failed."
I tried to extend the partition with the hided partition that we use when we can't boot on the main partition (I don't know how to say its name in english).
If someone have a solution, it would be cool !

Back everything up (preferably twice, 3 times for the really paranoid). I would use Carbon Copy Cloner and/or SuperDuper to make bootable clones to external disks.
Test the clone(s) by booting from them.
Repartition the boot disk the way you want it.
Restore your cloned system from the external disk.

IMac won't boot OsX Partition after Bootcamp install/uninstall.

Hello,
I have bought 2 late 2012 21.5 iMacs last year and have used both the same way. Here is what happened with one of them recently.
Fisrt af all I've installed bootcamp 1 year ago in both iMacs without issues and was ok so far, and was using exclusively Windows 7 partition. The trouble iMac started with some startup issues during boot/reboot (screen was frozen with green/grey horizontal lines), but worked fine after following manual start up.
Lately I've been trying to boot from OsX partition and it freezes in the apple logo every time.
I have already done the SMC / PRAM procedures, without success.
I have tried to download and do a fresh OsX install (Mountain Lion, Mavericks and Yosemite). Can't boot from Mavericks / Yosemite flash drive install (both freeze at apple logo - horizontal lines), and only had partial success with one Mountain Lion 10.8.5 flash drive install that booted all right and the first part of the installation process was ok, but after the initial reboot, it happened to freeze the same way before.
The iMac failed to boot in safe mode (stops booting at 25% and then freezes on apple logo), and show no issues with AHT tests.
I can boot in single user mode, but it reboots after a few seconds. I noticed some errors messages during this boot.
It fails to boot in verbose mode, showing a few lines of errors (images attached), and then freezes in a green horizontal line screen.
I can still boot from Bootcamp flash drive and Ubuntu Flash drive, and install both OS. The only issue is with OsX itself. I have used Gparted in Ubuntu to Format the hole partition to HFS+, and can't find any errors in hard drive tests.
I thought about buying a thunderbolt cable and try to do a Clone of my other iMac, but don't know if it will work.
Any other tests/suggestions about this issue?
Regards,

Fixed the problem with this setup
Of course this means i just lost 4GB.
Let me tell the full story.
In the beginning, long ago, once upon a time. My iMac had 2x2GB ram sticks which were in the two DIMM1 Banks. I then told myself "I WANT MORE RAM BECAUSE LOLZ". So i bought 2x4GB ram sticks. The two empty slots were Bank 0/DIMM0 and Bank 1/DIMM 0. and I added them in there. having done that, I booted OS X up, worked great, had 12GB, everything was shiny and beautiful. Soon after I wanted to try it out on windows. I restarted my computer and BAM the blinking cursor just sits there, being stubborn and all. I then told myself "holy balls, this new ram i got is bonkers" (them words, I blame the language filter). Then after giving it a little thought, i just asked myself if it was because I had ram from two different manufacturers. I removed my old ram, which has nice Samsung stickers on them, and booted it up on windows. Still had the same problem, I then decided that maybe this is all really mentally challenged so to win I had to think like a retard. I took my new ram and inserted it in the same slots where my old ram sticks were (DIMM1 Banks), booted windows up and IT WORKED.
I still hold all of my WHYs on this subject but I will keep messing around to see if I find a better solution than just leaving both DIMM0 banks empty

IMac continuously restarts after bootcamp failure

Hi, I hope I'm posting this in the correct forum!
I've just done a fresh install of OS X Snow Leopard on my 2 and a half year old iMac. (I wanted a clean HDD before going back to Uni), I installed all my software and finished up by trying to install Windows 7 Home Premium via bootcamp. Bootcamp partitioned the HDD and restarted with my legitimate Windows 7 disk in the drive. But now it doesn't start back up! Just a white screen for 10 minutes or so then it restarts again.
The only way I can get onto my mac is by holding down the alt key as it tries booting up and it lets me select my Mac HDD. That's the only one it shows. I remember having the same problem at the start of the year, so a fresh install of Snow Leopard should fix it, I know. But I've just done this once and it took all day to sort of my programs! It'd be a hassle to have to go through it again, is there anything else I can do?
Thanks.
Edit: I originally set 60GB for Windows, after that failed I erased the partition and tried again with the default 32GB. None of these attempts worked and after erasing the windows partition a 2nd time, it still doesn't start up properly. (My iMac is a 20" intel model) Thanks again

Hi,
to avoid the neccessity for the useage of the Option-key got System Preferences in OSX - then Startup Volume and set your OSX to be the Default Startup Volume.
After that your Mac should start automatically in OSX on the next reboot.
Then you can/schould use the BootCamp Assistant again to revert the done partitioning back to one single OSX partition.
Refer to the BootCamp Installation Guide.

IMovie -Problem restoring events after external hard drive failed.

iMovie 09 – The external hard drive failed where I stored my 2012 events. I do not have a backup copy of these events. I bought a new external drive and named it exactly the same as the old drive. Then I uploaded archived original video clips to it recreating the events. I used the exact same event names. However when I view the projects I made from the original events, I get “this clip’s media file is not currently available”. The file path I created should be the same as the old, so why does the project not recognize the recreated events? Any suggestions what I could try?
If I were able to retrieve and copy the old events from the failed drive to the new drive, would that work?
Has anyone successfully dealt with this problem?

That's a very interesting scenario that you've described. I've been concerned about a potential situation arising where I may need to restore Events from a backup drive. However, your situation is somewhat different in that you've had to re-import the Events to a new drive from an archive.
My main video drive is a Maxtor One Touch III Turbo comprising two 500GB drives set up as a RAID 0. So, effectively it appears as one drive totalling 1TB, with data being written to both drives simultaneously (but not mirrored). However, if one drive fails, the other becomes ineffective as it contains only partial data about imported clips (the remaining data being on the failed drive).
I backup the Maxtor to a portable 1TB drive by cloning it using SuperDuper. My thinking has been that, if the Maxtor fails then a simple rename of the backup drive to the same name as the Maxtor is all that will be required for iMovie to retain the linkages between Events and Projects. I hope this is the case!
I hope you get a solution to your predicament - sorry I can't offer any useful advice!

Restoring iTunes after computer failure.

Hi,
I am just setting up my new Windows 7 PC after the complete failure of my old XP PC.
I have a decent set of backups (but not an iTunes specific backup) and I have basically set up my data as it was on the old PC (same driveletters etc). I have loaded iTunes and it seems to be working OK - apart from the fact that it is empty.
I think that all I need to do is to copy the old My Music info (iTunes + extra library info) into the Music library and I should be back where I started. As a precaution, I would obviously save a copy of what is there currently.
Please advise.
It would also be helpful if you could suggest a more iTunes specific backup strategy additional to what I already do.
Thanks.

sorryociffer,
The backup you see taking place only copies certain information, and in general shouldn't be considered a primary back up of data.
iPhone and iPod touch: About backups
http://support.apple.com/kb/HT1766
To back up the iPhone data, sync the iPhone data to other programs on your computer (following article http://support.apple.com/kb/HT1386 ) and then back up all of the data on the computer to a dedicated back up device, like an external hard disk drive for example.
This article here provides basic information on creating data backups: http://support.apple.com/kb/HT1553
The message you're encountering is expected behavior. An iPhone and an iPod are only meant to be synced with one iTunes library at a time: http://support.apple.com/kb/HT1209
In this case, Apple does give you the ability to copy over iTunes Store purchases to an authorized computer: http://support.apple.com/kb/HT1848
Beyond that, there are other non-Apple programs that claim to give you the ability to copy all of your music, and possibly other data from your iPhone to your computer. It's pretty easy to find one when using an online search engine, like Google, Yahoo, or AOL.
Hope this helps,

Trouble with restored disk after HD failure

My HD failed and I restored it using a backup from time machine (complete reinstall using the CD) Now, when I move something to the trash it asks for my password. When I move folders the changes don't stay made when the machine is restarted. So far I have:
1. repaired permissions both from the desktop and from the original install disk.
2. verfied disk...volume is OK
3. Trashed the com.apple.finder.plist file.
Still having the same problems. Anyone have any other suggestions?

Reading this thread here you may have a permissions issue with your Home folder. If that is the case then Kappy's post in this thread http://discussions.apple.com/thread.jspa?messageID=10675415&#10675415 detailing how to reset the permissions on your Home folder should help (obviously substitute your own name where required).

Problems restoring Backup after disk crash & exchange

Recently, the harddisk in my iBook started acting up and eventually died. I had made a backup three days prior to the crash, so I still have (most of) my data.
I brought my iBook to an Apple repair shop, where they mounted a new hard disk. So far so good.
Unfortunately, I've been trying to put my backup on the new disk for the last five days, without succes.
At first I thought it might have had to do with the diskimage I had, like "unreadable" names, but even after rewriting the image to a read/write one, and deleting or renaming the files that had unfortunate signs in it, I still keep getting an error, namely
" An error (2) occurred while copying. (No such file or directory) "
I can't find what's going wrong, I tried everything I could come up with - even simply extracting the files to the disk, but this of course skips most of the hidden files; and when doing this from within the terminal, I still get "Permission denied" errors...
If anyone could help me on this one, I'd be very grateful!
Ah yes, the backup is on an external FW disk, from which I can also boot - which is what I'm doing right now as well; so it's not that I can't write to the disk because it's busy as the bootdisk.

*\mood happy*
Booting still failed this morning... So I thought I'd delete some files from the image to make it copy faster...
I tried Silver Keeper again (when choosing a source, it asks whether one wants the destination to become bootable); and this time - it worked.
I have CCC as well, but haven't tried it.
Anyway - the disk has now been restored and is bootable, so I'm happy. I'll still have to copy back a few directories (the ones I deleted, together around 40gigs, homemade pictures and movies... Not really necessary for a diskrestore at first, I figured), but it works now.
Thank you again; for helping me, but also for teaching me (indirectly as well) a few things about the Mac filesystem.
*end of report with a successful recovery*

How to access Mac Partition after bootcamp

I've just recently bootcamped my Mac and now i have windows 7 and that is working fine but now when I try to get onto Mac Partition it dosent work. I've tried to restart my Mac but it hasn't worked I can't access the Mac Partition it is just stuck on the loading screen when you turn the Mac on and stays like that. How do i fix this or just access the Mac Partition

Hi,
usually you hold down the Alt/Option-key at startup of your Mac to get the Boot Selection screen.
There you can choose which Operating System to boot into.
Once in OSX you might wanna go to System Preferences - Startup Volume and set your OSX to be the default.
If that's not working you should boot from your OSX Install DVD (holding down the C-key at startup) and use Disk Utility from it to verify/repair your harddisk/OSX.
Regards
Stefan

Problems with partitions after hard reset

Hi hope some can help here, I installed Maverick on my imac and everything seemed fine, I went to work and came home to find a black screen with nothing but the mouse cursor, however the computer wouldnt respond in any way so had to do a hard reset when the computer restarted I would get the Aplle logo and the spinning wheel then the computer would restart it kept doing this over and over.
I restared the computer went into DU tried to repair disk and kept getting errors, my drive is 3TB i have a 1TB primary Partition and a second of 2TB I tried to erase and reformat the primary partition but got an error half way through now both partitons are greyed out with no way or deleting or doing anything with them I have also noticed I no longer have the hard drive make and model in the list just Mackintoh HD and my second partition, to make matters worse my second partition is now unmounted and and when I try to mount it says it needs to be repaired but wont repair, I really need totry and get the data from the second partiton but im struggling, when I tried to reinstall os x it cant see a drive to install to nothing shows up, I even booted using diskwarrior and even it couldnt see the drive, I know this drive is ok this is a software issue the partition table seems to be corrupt or something help!!
Its worth mentioning I had Parallels and Windows 7 on the primary partiton could the windows partiton have caused an issue when I tried to erase and reformat the partition?

Create 3rd partition after installing Windows 7 on Macbook Pro (Lion preinstalled)?

Hi, currently I'm having 2 partition: Macintosh HD - Lion (~680GB) and Bootcamp - Windows 7 (~60GB). Now I want to take ~600GB from the 1st partition to create a FAT32 data storage. My question is: is it possible to do so without reinstalling any OS?

Do not add a partition after BootCamp. BootCamp manipulates the boot-sector of a Mac disk to allow dual-booting. But manually adding a third partition will break that tenuous multi-boot balance.
Many threads posted by people who need to restore OSX from a backup and lose their BootCamp data due to system instability attest to the tourble you can cause.
Buy an external drive and use that for FAT32 (or EXFAT to allow files larger than 4 GB) storage.
