Windows 8 installation w Bootcamp: partitioning doesnt work

Hello,
I try to install windows 8 with Boot Camp on a brand MBA 2013.
At the step "Create a Partition for Windows" I select the size of the partition, click install and then ..... Nothing happens. The progress bar under "Status: Partitioning disk..." is animated but actually nothing moves: the progress percentage stays to zero and nothing happens during hours.
If I Force Quit Boot Camp Assistant, the MBA is not partitioned: stil one disk with original space. I tried to verify the disk: no problem. I repaired the Disk Permissions, restarted: same problem.
Can you help me please??!! Thanks in advance :-)

Welcome to the Apple Support Communities
First of all, Boot Camp isn't compatible with Windows 8 because Apple hasn't released Boot Camp drivers for it, so do it at your own risk. If you don't want to break the Mac, install Windows 7.

If you didn't erase OS X, press X key while your Mac is starting to start into OS X, open Boot Camp Assistant and follow the steps to erase the Boot Camp volume.

Open Boot Camp Assistant and follow the steps to install Windows. When you are on the partitioning screen, format only the BOOTCAMP volume and install Windows on it.
Boot Camp Assistant will ask you to download the drivers, but now they are useless for Windows 8

    Hi wb2009,
    I haven't found that the TV would be an issue, but did find an article that states to not have extra USB devices connected.
    Boot Camp: Windows installation boots to black screen with blinking cursor
    http://support.apple.com/kb/TS4536
    The Windows installation may boot to a black screen with a blinking cursor. This can occur if you use a USB optical drive or USB Flash drive for the Windows installation and another USB device is also connected to the computer.
    There's another article that mentions Windows XP or Vista that may apply.

  • I have recently installed windows XP on my bootcamp partition. I am in need for the drivers and what not so that it will run effectivly and the bootcamp assistant canot find the "Windows Support Sofware" Can anyone help me find it manually?

    As the title has stated, I have recently installed Windows XP on my Bootcamp Partition. I am in need of the "Windows Support Software". I am assumeing that is the information that has the Drivers and what not that allow me o properly use my Mac with windows. If anyone can help me locate this inforamtion i would be greatly.... Greatfull.
    P.S. The bootcamp assistant is telling me that the Windows Support Sofware canot be found.

    You both would have had correct awnsers, but i have a Macbook that is close to three years old. And i can't seem to find my Disc. The only reason i haven't ordered a new one in case of emergencies is I plan on upgrading to the new OS in less then a month.

  • Installing Windows 8.1 with bootcamp, partition issues.

    So I am trying to install windows 8.1 onto my MBP running the latest 10.9.2 operating system. It took a while to get the HD to successfully partition, however when I finally got it working, upon booting from the USB drive I got this error message
    windows cannot be installed to this disk. the selected disk has an mbr partition table windows can only be installed to GPT disks
    Is there any way to change the partition table or to fix this?
    I just tried restoring the partition to one, verifiying and repairing the disk in recovery mode, then re-running boot camp, issue persists.
    running late 2011 15" MBP

    Well, when you start the computer you should press ALT to show the boot manager. With Windows 8 and 8.1 (for Windows 7 there's not this problem) there should be three different icons: the OS X one, and then two called Wininstall (or something like that) and the other is similar but there should be written something like "EFI Boot".
    Well, don't choose the EFI Boot one and you should be fine.
    If you choose the first one the Windows installer format the Bootcamp partition correctly, and then you can start the procedure.

  • Can I install Windows 8.1 as Bootcamp partition from OSX Mountain Lion using a USB stick?

    I have the following:
    Bootable USB stick with Windows 8.1 - 64 bit
    MacBook Pro with Mountain Lion 10.8.5 - it's probably 3-4 years old.
    The Bootcamp partition currently has Windows 7 installed.
    I want to know whether I can install Windows 8.1 from a USB stick into a Bootcamp partition. Apple's article on the topic refers to Bootcamp 5.1, but my OSX install has Bootcamp 5.0 - I am assuming 5.1 comes with the Mavericks version.  I don't want to upgrade to Mavericks because I am running out of space as it is on the OSX partition.
    Thus my question. So can I?

    Your laptop has a DVD drive, right? If so you need to burn your ISO to a disc, will not work off USB

  • Upgrading MacBook Pro Hard Drive - cannot get Bootcamp partition to work

    Hello,
    The other day, I decided to replace my 320 GB hard drive with a 1 TB hard drive/SSD hybrid. I did a little bit of research about cloning the drive before that, and it seemed pretty straight forward to clone the OS X partition, but I wasn't really sure about cloning my Windows partition. Originally, my 320 GB hard drive had 2 partitions: 220 GB for OS X Mavericks, and 100 GB for Windows 8.1.
    I bought the new drive with an external enclosure and plugged it in. The first thing I did was open Disk Utility and partitioned the new hard drive (750 GB HFS+, 250 GB NTFS). I figured I would need to partition it first and clone each partition separately. I used Carbon Copy Cloner to clone the OS X partition, and it worked with no problem (I immediately could restart my computer and boot with the partition on the new drive, while it was still plugged in by USB).
    Next, I tried using CCC to clone the Windows partition the same way (I realize now that CCC cannot do this). 7 hours later, the cloning was complete, but there was an error that a couple files couldn't be copied. I tried copying them manually but it didn't work. I wasn't sure if the Windows partition would work, so to find out, I switched the hard drives and put the old 320 GB one in the external enclosure. I booted my computer and it booted the new OS X partition with no problem. It also mounted the Windows partition that I cloned with CCC, and I can access all of the files in it. However, when I restarted and held down "option", it would not let me boot the Windows partition.
    After some googling, I realized CCC is not able to clone a bootcamp partition and make it bootable, so I opened disk utility and deleted the Windows partition (using the minus button), then recreated it (using the plus button). I downloaded Winclone (paid $30), which supposedly can clone a bootcamp partition. I opened Winclone and it seemed pretty simple: you just choose the source partition on the left, and the target on the right. I plugged in the USB enclosure with my old hard drive, and in the Winclone menu the original Windows partition popped up. I chose that as my source, and chose to copy it to the new NTFS partition on the new drive that I created. I left it on overnight, and when I woke up it said it was completed.
    I now had two drives mounted: my NTFS partition that I created, and a new one that said "EFI". I have no idea what EFI is. My NTFS partition looks like it has all of the files from my original Windows partition on it; however, when I restart it does not allow me to boot with it, although I now have the option to boot EFI. When I select EFI, I am given the Windows 8.1 start up screen (with the blue Windows logo), but then an error message pops up saying something like there is an issue and it needs to restart (it restarted before I could read the whole thing).
    When I boot in OS X, I only have the NTFS partition (with all my Windows files) mounted, and no EFI. When I restart, I can still boot EFI, but I always get the same message and then it restarts.
    Is there any way I can fix my Windows partition so that it works the same way it did on my old drive? What is EFI? Can I delete it? How can I make the NTFS partition, which seems to have all of my files, bootable? I only want 2 partitions: one for OS X, and one for Windows. Also, can I do all of this without having to reinstall either of the operating systems?
    Thanks

    Hmm, that's a good question!
    I headed over to the twocanoes website (the folks that make Winclone) and their guide mentions something about running Sysprep before you create the Windows image. If you skipped that step, that may be why you're having issues
    http://www.twocanoes.com/support/winclone/migrating-a-bootcamp-partition-with-wi nclone/
    Step 24 in that guide also mentions copying a Boot file - were you able to/did you do that?
    You may have better luck over in the Bootcamp forum, which is here.

  • Installing Windows 7 on my bootcamp partition (mid-2009 mac book pro with mountain lion) My computer won't boot from the Windows 7 Install DVD.

    Hello,
    I have been trying to install Windows 7 on my macbook pro (mid 2009, MBP53). I have successfully created a bootcamp partition using the assistant. When the computer tries to boot from the windows 7 install dvd, the screen is just black. The dvd spins for a bit, then stops and the computer is just black (no blinking cursor).
    Any advice would be very appreciated.
    Thanks.

    What kind of an install DVD are you using for Windows?
    You can use any DVDs that are hardware specific. Only the full non-hardware soecific DVDs work on the Mac.

  • Can't complete Windows 7 installation - mouse and keyboard wont work

    I'm trying to install Windows 7 on my new iMac and am running in to a problem. I have the comprehensive instructions document printed, and am following it. I've created the partition for Windows using Boot Camp Assistant, I've inserted the Windows CD and selected Start Installation in Boot Camp. The computer restarts and loads up from the Windows CD. All good so far. It loads some Windows files and then the installation options pop up asking me to select language, country etc. Its here that I get stuck, as my iMac's wireless keyboard and magic mouse have stopped responding.
    I thought I must have missed something and have reread the instructions, but there's no mention of the iMac's peripherals not working during the Windows installation. What am I to do? I don't have any other USB mice or keyboards to hand if that's the solution.

    Just a follow up question on this - does the size of the partition have to just be enough for the windows installation itself, or for all programmes you would want to install to run under Windows?
    I've set the partition size at 32gb for a windows 7 installation, but im thinking if it has to be big enough for my games collection i'll need to start over the partition 50/50.

  • Installing Windows from virtualisation onto bootcamp partition - formatting problem!

    Hello!
    I hope I can describe this well enough.
    I'm in the situation of trying to install Windows 7 from a .iso I've made as my superdrive is totally dead. I'm running 10.7.4.
    Currently what I've done is basically the first chunk of steps from this post:
    Installing Windows 7 on MacBook Pro without SuperDrive | CommitBlog
    I get hung up on the windows installer right away though. When I'm installing windows into my raw disk (bootcamp.vmdk) I get this:
    "Windows could not format a partition on disk 0. The error occurred while preparing the partition selected for installation. Error code: 0x80070057"
    I've tried reformatting the partition I made with boot camp assistant to NTFS preemptively with Paragon NTFS in hopes that the installer would skip the formatting step, but no dice.
    Any thoughts on how to move forward here? Is there a permissions change that I somehow haven't made? I can't seem to find any documentation or posts on anyone in exactly this situation.
    This is a really pressing problem actually, so quick responses are especially appreciated!
    All the best and thanks in advance
    -Ijnad

    I've actually resolved this!
    Well, not that I fixed it. But I was able to hack into Boot camp assistant and convinve it to let me make a bootable Windows 7 Usb key and install from that!
    peace

    The History: hard crash... restore everything
    Unable to restore from time machine.
    Installed OSX Maverricks via Internet Recovery
    Installed Windows 8.1 Pro via Boot Camp
    Transfered Data from Thunderbolt External HD via Migration Assistant (Crashed twice, worked on third try)
    I was able to get my stuff back in working order including Bootcamp To run windows... The trick was to install windows before importing data with migration assistant. Loading Windows would fail if I imported migration assistant data before hand.
    The Problem: I have a windows backup 30gb ISO from before the crash that I want to load up. Has anyone performed this? is there a way to get my windows data re-installed into this machine?
    Is it possible to load the System Restore into a USB and simply just re-installing the earlier date ISO?
    any expertise in restoring my Windows Partition would be greatly appreciated.

    Windows Backup Restore goes through all the prompts.
    When it's at the step to start writing to the partition I get an error along the lines of it can't over write to that partition. I wish I had a screenshot of the error message.
    My BootCamp Partition is 120GB so the 30GB ISO should extract no problem.
    Either way, I think I am SOL
    I dowloaded winclone 4.4 and that too was a catastrophic fail with a test partition.
    There should be an easier way to back up and restore your BootCamp Partition. In todays day and age Software like TM should be able to image your entire system. All it's partitions, and give you the ability to restore everything to a certain point in time.
    This has been a huge ordeal, I'm shocked that Yosemite, wouldn't even restore from Time machine. Looking through this forum, TM has a lot of issues in Yosemite. Thankful Migration Assistant at least gave me my data back (after two very worrisome crashes)

  • Windows 8 woes on bootcamp/partitioning/help please!

    So, I ordered a copy of windows 8 OEM edition 64bit. I'm on a late 2012 macbook pro 13 inch with mac os x 10 mountain lion.
    I recieved it, started up bootcamp did as it said and then when i came to installing windows the partitioned hard drive I'd created (100gb) for windows wasn't useable. Windows 8 said "can't use *bootcamp partition I forget the exact name/perhaps partition 4*. Windows gave me the option to format the drive. So i did. And the drive was then obviously no longer boot camp and has turned into a standard NTFS drive (I'm not that clued up on this go easy on the terminology for me!). In short, I then continued to install windows 8 on a none bootcamp partition.
    This installation doesn't have the drivers needed (probably from bootcamp) for use of the macbooks dvd drive or the volume/media/keyboard light buttons it doesn't recognise the wifi card or anything..
    So i guess I need to know these things:
    1) how do I uninstall windows 8 from that partition and then restore that partition to recreate the whole, original volume? Is there a way of uninstalling windows that means I can use it again (i.e. I don't want to be paying another £60 for the privilage of a new license)
    2) how do I do the PROPER bootcamp installation? and what happens if I hit that bit where windows 8 doesn't like the bootcamp partition i created?(i know not to format the hard drive now!)
    Thanks for any help guys, much appreciated!

    Now I want to upgrade 'Windows Vista' from win XP. But when i start my Mac by inserting Windows Vista bootable Cd (holding "options" on key board -> and selecting the Win Vista Cd) it asks to *press any key to start installation*.

    If you want a collection to be available to the designer then one way is explained here:
    http://social.technet.microsoft.com/wiki/contents/articles/26200.wpf-dynamicresource-observablecollection.aspx
    There's a bit of a strange looking class:
    public class ColourCollection : ObservableCollection<SimpleColour>
    You can then have some data set up for that in a resource dictionary which is merged in app.xaml or in app.xaml itself:
    <Application.Resources>

  • How to install my company's image of Windows 7 onto a Bootcamp partition?

    My company uses a reimaging DVD to install Windows 7, MS Office, and all other propietary company software and settings.  On a PC, you boot to the disk, it asks is you want to erase the entire and reimage the entire disk.  It does not recongize partitions to allow you to choose which disk is erased and reimaged.  I assume it would reformat the entire HD, removing partitions, and reimage the whole thing with WIndows 7 erasing the Mac OS.
    The disk is made up of a boot folder with a etfsboot.com file.  I'm assuming that this is where the process starts.  It looks like they may have used imagex to create the image.  There is a WIM file along with 4 SWM files which I'm assuming contain the image rebuild.  There are several other support files but none of significant size.
    I've read a ton of different blogs and forems, but I can't find anything that addresses my situation.  Bootcamp doesn't recongnize the disk or the boot file as a Windows 7 install disk (I didn't think it would, but it was worth a shot).
    How do I get this image onto a bootcamp partition?

    You need a full retail version of Windows in order to install Windows on a Boot Camp partition. Ask your IT Admin or whoever created the image why it does not install on an Apple computer. We have no idea what they put on the disk with respect to software, security, etc.

  • I used bootcamp assistant to partition my hard drive to install windows.  When I got to the part to install windows, I selected the bootcamp partition and then choose format as instructed but it would not continue stating that the partition was in GPT par

    Please help!!  I partitioned my macbook pro hard drive in bootcamp so that I could install windows.  Everything appeared fine until I got to the install part.  I selected the BOOTCAMP partition and then selected format as instucted.  That was it.  The install could not proceed because it says the partion is in the GPT format instead of NTSF.  At this point it erased the "BOOTCAMP" name from the partion but the partion still exists. 
    I tried to reform by going back on the OS side, in disk utitly, erase and format.  It will not allow me to select NSTF format.
    What do I do to fix this??
    Thanks for you comments.
    Kristina

    In Boot Camp Assistant when you select the format option the Boot Camp partition it automatically formats the Boot Camp partition as NTFS since this is what Windows requires. There is no option to select NTFS or any other format type.

  • When you set up a windows os on the bootcamp partition, do you have to treat the computer like a pc with all the maintenance proceedures, like defrag, antivirus and malware software?

    When setting up Windows 7 OS on a partition through bootcamp, do you then need to treat it like a PC?  Are the same precautions necessary to run an optimal system using proceedures like defrag, disk clean up, and runinig antivirus and malware programs now necessary?

    It is (once installed) Windows, and needs to be treated like any other copy of Windows on any other machine.
    Use Microsoft Security Essentials for anti virus, defrag and cleanup is up to you, it is not necessary but may be desirable now and again. Anti Virus is not optional.
