Boot Camp Partition Size Problem

Hi there,
I've got a strange sort of problem:
Running a MacBook Pro, late 2011, with an Apple 256 SSD (installed at purchase), running latest Mountain Lion.
Currently, when I get info from my HD, I have 80+ gigs free.
I want to install Win7 in Bootcamp (I have Parallels but I want to play some heavy graphic games which respond really slowly with virtualization). So I run Bootcamp assistant, and the biggest partition it says I can make for Windows is...30 gigs.
Why? I know that Mac requires at least 10gigs free (that's fine), but that should still let me get up to around 40 gigs (which is what I figure I'll need with all the installs I want to do). So....what can I do to fix this?
P.S. I know that defragging an SSD is a bad idea, and probably dosn't work anyway, so I'm not doing that (and I know you don't need to defrag in OS X anyway)
Thanks for any input. I'm a tad frustrated at this point. I already did a full backup with time machine in case anything would go wrong, downloaded the drivers to the USB thumb drive, have my Win7 CD ready...and I just can't get beyond this.

Wow that's very strange. It says I have 42 gigs free, but when I get info on my drive, it says 82 gigs free.
Ok, so I read the article, and I see the problem. I just used terminal to kill snapshots (as I really don't need that...).
I tried finding the backups in /Volumes, but all I have in that folder is an alias to my HD. Any idea where else they could be? I tried using search in the finder to no avail.

  • HT3777 Reducing Boot Camp partition size

    I've never used Boot Camp since I bought my MacBook Pro in 2008 since it came with a free VM Fusion program.  I have Boot Camp with nothing in it taking up 33 GB of space and I need the space.  How do I reduce the Boot Camp partition size?

  • Recommended Boot Camp Partition Size for Windows XP

    All,
    What size is recommended for a Windows XP Boot Camp Partition? 100Gb? 50Gb?
    Main use is to run a few programs that are not available for Mac. Most everything else will be transferred over.
    Thanks

    Depending on the programs you want to install, you can get by with very little. I have virtual XP systems that live within 8GB virtual disks. If you've got the drive space, go for ~30GB. I've found that to be a nice size for running Windows 7 within, and thus you likely won't have to mess with re-partitioning should you update the OS in the future.

  • Boot Camp Partition Size/External HDD recommendation

    After updating software, hardware, downloading Boot Camp Asst, and installing Windows XP Pro (have not yet downloaded Mac drivers or software, nor have I submitted registration of my WinXP Pro software, still have 29 days), I realized that I set the partition size too small and need to resize it. I read in other postings that I can copy the Windows partition to an external HDD from the Mac OSX side, then run Boot Camp again, delete the "too small" Windows partition, then run Boot Camp again and reset the partition size larger. Does anyone have detailed instructions to do this?
    Also, can anyone suggest an external HDD for this purpose? I need to be able to share files between a PC and my 17" MBP running OS X 10.4.6. Specifically, I need to share (for editing purposes) audio files created with PC-based software with the Windows side of my MBP. The PC has XP Pro and MacDrive6 for Windows installed. I read the "Sharing a FireWire drive between Mac and PC" document on "The X Lab" website and, based on this, am leaning toward getting a FW (not USB) HDD and formatting it in Mac OS Extended format (not sure how to do this but cross that bridge when I get there). Does this sound reasonable? When I run Boot Camp again and have to choose between NTSF and FAT32 should I choose NTSF? Will I also need "SharePoints" or other software to share the Mac's FW drive with the PC?
    I may have the option to share and backup files over the workplace network (if I take the time to set it up). Does anyone know if there advantages/disadvantages to this option?
    Thanks for answers to these questions. Any help would be very much appreciated. Best!

  • Boot Camp Partition Size?

    I'm thinking of installing a boot camp partion. Does boot camp choose the size or do I. If I do, what's a good size to make it. I really will only run Office 2003 and my BlackBerry Desktop software and some browsing with IE.

    Brand new Mac user here who just made "the switch".
    I've also wondered "how large should I make the partition?"
    On the Windows partition, I intend to install XP SP3, Microsoft Office Suite, Project, Visio, and Adobe Acrobat/LiveCycle/Photoshop (at least those are the "heavy hitting" apps.) I also plan to run Parallels.
    I was alarmed to see that the suggested partition size for Vista is 60-70GB. But I never migrated to Vista because of all of its issues, bloatware, etc. and stuck with the tried and true XP. When I look at the tech specs for XP, the suggested available space is substantially smaller than the space required for Vista.
    I see that Boot Camp Assistant defaults to 32GB and that anything higher than 32GB prevents sharing between partitions.
    So some questions:
    1. Is 32GB enough/not-enough/more-than-enough size for my intended OS/applications indicated above? As it is, my HDD is 320GB.
    2. Do I care about sharing between partitions? More simply put: if I am running Parallels and running MS Word (which would be living on the Win side of the house), will I have the option to save my doc on the OSX side only if the partition is <32GB?
    3. And as follow on to #2, what are the ramifications of creating a Win partition >32GB from a usability standpoint? I'm having trouble discerning what those really are in layman's terms.
    4. Please confirm: when I run Boot Camp Assistant, should I create the Win partition as NTFS? Is this dependent on the size of the partition and if yes, what are the suggested formats in regards to size?
    Any guidance would be immensely appreciated.

  • I had to replace my iMac due to hard drive and Logicboard failure, so I want to reinstall Windows 7 on a Boot Camp partition. Will there be a problem reactivating Windows 7 Home Premium?

    Hi,
    should be no problem.
    Best case is you can activate online via Internet.
    Worst case is you have to call Microsoft and explain that it is the same computer after a mainboard failure.

  • Boot Camp Partition & Windows Vista - Disk format Problems

    When Boot camp partitions the disk (I chose 25gb) it automatically formatted it as FAT32. However, when installing Vista, it says that it requires the disk to be formatted as NTFS.
    The Boot camp instructions says I should be given the option which format to use, but no option came up. I don't want to partition more than 32gb.
    How do I get Boot camp to format the partition correctly?

    Read the instructions that come with Leopard Boot Camp. The partition is automatically formatted at FAT32. However, it's a) not bootable (Windows has to do that) and b) Vista requires NTFS. That means once you're in the Vista installer you need to REFORMAT the partition. Select the partition, and then click, umm, disk options I think. Then reformat the drive. If you do that you should be able to continue.

  • Any way to reduce the size of Boot Camp partition?

    I made my Boot Camp partition way big and now I'd like to smallify it by about half, down to 60G or so (it's 130G now). Is there any EASY way to do this?
    Many thanks,
    Pier

    In Vista (Ultimate in my case), RightClick My Computer -> Manage: select Disk Management. In Vista you can shrink your (C:) Boot Camp partition which leaves OS intact but allows another install to new (D:) (extended) volume created within space. In XP, I think same can be done with Diskpart.exe which is in \System32. As I have, you can install another Windows OS to the new partition.
    I can't see data from Leopard OS for the extension made, though I can see Ntfs files and copy/paste from original Windows (C:) volume bootcamp set up. I do not know if formatting the new split to Fat 32 would make it a share space for Leopard.

  • Can no longer see Boot Camp Partition

    Hello all,
    I was having problems with booting into Boot Camp/Windows 7 (I was just getting a black screen), so I attempted to delete the boot camp partition and reinstall it.  When I did that, the program hung for a while, and finally said there was an error deleting the partition.  However, it appears it like halfway deleted it, as it no longer shows up!  When I go into disk utility, Macintosh HD shows blue, and then there is a 50 GB partition (the size of my bootcamp) that is white, but it is unlabeled.  I cannot adjust the partition to make it the whole HD, and if I go to boot camp assistant, and try to make a new bootcamp partition, it bounces back with an error message as well.  I am wondering how I can restore the partition back to the original all mac hd partition..ANy help would be greatly appreciated!!

    WinClone 3 $20
    When you move to a new OS: clone your system, make sure you have backups you can use - for each - the partition table "rules" change with each new OS. And you want to reformat a drive from time to time especially then.
    Carbon Copy Cloner 3.4 is a good way to clone your OS X partitions.
    Basically, "start over" and restore to one HFS volume with OS X then run Boot Camp Assistant, then restore with Winclone image you made easier.

  • I have recently purchased a hybred 750GbHDD as an upgrade for my MAC Book Pro (Intell Version) I have a boot camp partition to the original 500GB HDD. How can I expand both partitions to fit the new drive?

    I have recently purchased a hybred 750GbHDD as an upgrade for my MAC Book Pro (Intell Version) I have a boot camp partition to the original 500GB HDD. How can I expand both partitions to fit the new drive?
    I have tried bootcamp and have had no luck due to the fact that boot camp doesn't see the additional HDD space of 250Gb. What am I not doing?

    Ouch, well there is a problem.
    This is the stack of partitions on your old drive
    EFI (hidden)
    Lion (50GB say)
    Bootcamp (50GB say)
    Lion Recovery Partiton (hidden)
    This is the same stack on your new drive imaged from the old one.
    EFI (hidden)
    Lion (50GB say)
    Bootcamp (50GB say)
    Lion Recovery Partiton (hidden)
    Emtpy Space (100GB say)
    This is what you want
    EFI (hidden)
    Lion (100GB say)
    Bootcamp (100GB say)
    Lion Recovery Partiton (hidden)
    EFI has to be at the top of the drive and Lion Recovery has to be at the bottom of the drive.
    And you only have four partitions.
    You can't move the Lion Recovery Partition or Bootcamp partiton, however you can expand the Lion Partition into empty space below it. (but can't delete or move the Lion Recovery partition)
    Your Duplicator duplicated perfectly, too perfectly Likely would work with same sized drives/partitions.
    This is what your going to need to do.
    You need to move the Bootcamp partition to a blank external drive using WinClone and disconnect. This is so you have two backups of it. (one on your old 500GB drive)
    You will need a drive enclousre or IDE/SATA to USB adapter cable for the older 500GB drive and option key boot from it. (some enclosures can't be booted from so check first Other World Computing is good place to ask)
    Download the free Carbon Copy Cloner, grab any new files off the new 750GB internal drive to the old 500GB your booted from.
    Open Apple's Disk Utility and Erase with Zero option the entire internal 750GB drive and let it rip, this will map off as many bad sectors and improve reliability.
    Now use Carbon Copy Cloner to clone the 500GB Lion + Lion Recovery Partitions to the internal 750GB, it will "fix" things and place Lion Recovery at the bottom of the drive where it belongs, give all the extra space to OS X Lion.
    Next your going to have to follow WinClones instructions to restore your Bootcamp, likely you will have to recreate the Bootcamp partition first (in Bootcamp) to the size you want and then clone. Likely Winclone may "fix" Windows to recognize it's in a new larger partition now. I don't know you'll have to check as I haven't used it.
    When Bootcamp creates the partition it will place it near the bottom next to the Lion Recovery Partition.
    As you know you will have to re-validate Windows with Lord Redmond or it expires as you changed the hardware.

  • Can't see Windows 7 Boot Camp partition from Mac

    I've had a Win7 boot partition on my 2011 MBP for a while and it boots just fine. I have a Mac boot partition, a Mac data partition, and a NTFS Win 7 partition. But the Boot Camp partition is greyed out and invisible when booted in to the Mac.
    When in Windows, I can see and use the Mac partition from Win7 with MacDrive. The problem is that I cannot see the Windows partition from the Mac. I have Paragon NTFS for Mac installed as well as MacFuse. I tried to see the partition with CampTune and got this error:
    I also tried going to the BootCamp Assistant and saw this:

    Does anyone know if I can repair this without having to re-format? I have a 13" White MacBook as well and this setup works just fine. I did it such a long time ago that I forgot how I did the first one.
    There is another thread on here that similar but not quite like my problem because I ca actually boo into Windows.
    If anyone can help it would certainly be appreciated!

  • Help-Erasing a Boot Camp Partition Caused 32 GB of Disk Space to Vanish

    Hi
    I'm a new mac user I'd I have been really happy so far, expect for this problem:
    -I created a 32 gb partition with boot camp.
    -I tried installing windows xp without knowing I had to format the system to NTFS during the install
    The installation didnt work, and I erased the bootcamp partition.
    -When I tried to create a new boot camp partition, it said my Mac HD size hard drive is 227 gb, ie the *32 gb allocated to the partition had vanished*. In addition, I could not recreate a partition because of an error message.
    -I ran the snow leopard CD's disk utility and thought that I had fixed the problem.
    -However in boot camp, the mac drive is still only 227 gb (missing 32 gb). I can create partitions now, and deleting these partitions does cause any additional loss of disk space.
    -I tried erasing empty disk space with no luck.
    Does anyone know how to recover space lost by Boot Camp?
    Thanks

    Let me ask a simple question. What size HD do you have in your Mac? You say you see 227 GB and that 32GB is "missing". If I add those two numbers up I com up with 259 GB. I suspect that your "missing" space is due to the inconsistencies in which Snow Leopard now reports 1 GB. In some places it reports 1 GB as a hard disk manufacturer (1 GB = 1,000,000,000 bytes). In other places it reports 1 GB as a binary number (1 GB = 2^^30 [IIRC] = 1,073,741,824 Bytes). Since I do not know of any drive manufacturer that sells a 259 GB drive, I suspect that this is just due to the differing definitions of 1 GB.
