Bootcamp windows 7 x64 installation on macbook air 2012 installation screen problem

Below are some pics on what happens after osx restarts to boot into the USB - windows 7 installation.. tried 2 different USB drives and got the same result. any ideas? please help.

Well, I've seen lots of those threads as well and most failed to manage cooperation of Bitlocker and FileVault, have trouble to get a second partition for windows to use with bitlocker or truecrypt etc. But these issues don't apply to me anymore.
Next there are threads instructing how to get a USB stick to work with Bitlocker claiming to have GPT instead of MBR so EFI is gaining any access on them. Those cases seem to work with MacBooks running with Windows, only, thus passing the issues mentioned in paragraph before as well.
And there is my confusion originating from: I can remember some sites claiming to have trouble with EFI on a Mac using Lion, but all those sites are older than Lion's final release date. So I don't know if there is a similar issue today or if I'm actually missing some option ... rEFIt isn't working with Lion according to the refit site itself. Some sites claim EFI is behaving differently on whether there is a super drive or not as Lion isn't supporting USB booting as long as booting from DVD/CD is available ... what's true about those facts? Is my problem related to having a super drive? Are things getting better as soon as I'm replacing my superdrive by a second internal drive? Is it that strange or some sort of plausible behaviour?
According to GPT, Windows 7 is obviously failing to properly detect hybrid MBR/GPT setups on USB sticks while that's what MacOS' disk manager is doing on having GPT-based single partition stick with exFat format. Instead of using the second hybridized partition it's accessing the protected part, only. If I'm converting a disk to GPT in windows everything works fine, but then without hybridized MBR ...
Regarding the fans I'm with you ... as soon as processor load is exceeding 5% the fans get quite noisy ...

  • Macbook Air 2012 Spotty Unstable Problem WIFI

    I have a Macbook Air, love the machine. It has  had wifi problems. All other computers in the house work but this one hangs on loading internet pages and when I renew the lease it sticks further. The problem is more frequent. I reset the modem. Erased all the wireless connects to the computer and still have the issue. Months ago I called apple about it. They had me reset something I dont know how to do and it worked again but now the problem is back. I am worried about my investment in this product.

  • WINDOWS SUPPORT SOFTWARE FOR MACBOOK AIR 2014

    Does anyone know if there is a windows support software for MacBook Air 13 inches 2014 version?
    I do need it desperately

    Again, what do you mean by a Windows Support Software?
    Bootcamp will allow you to install Windows on a Mac. Beyond that what else do you need?
    The instructions don't mention anything about Support Software.
    How to install Windows using Boot Camp - Apple Support
    For All intents and purposes Bootcamp is the software that supports Windows installations.

  • How to reset my macbook air 2012?

    hi,, my name is jovito ,,i have this macbook air 2012,, and i planning to buy the new version,, and my friend want to buy my 2012 air.. but before he buy this air,, he wants me to reset it first.. and i dont kmow how to.. please help.. thank you...

    Before you sell or give away your computer, in addition to the steps mentioned in this support article, take these steps:
    Run the Apple Hardware Test or Apple Diagnostics. The buyer will do this (or he should), and you don't want to be surprised by the results.
    Reset the PRAM and the SMC, which might contain personal information.
    If you set a firmware password, remove it by running Firmware Password Utility in Recovery mode.
    If you activated FileVault in OS X 10.7 or later, turn it off.
    If you use Boot Camp, the partition must be deleted
    If you created any other data partitions on the internal drive, remove them in Disk Utility.
    Erase the data partition(s) with the option to zero out data. An SSD doesn't need to be zeroed.
    You can't legally or practically transfer any software downloaded from the Mac App Store to the new owner of the machine, even if it was free. That includes OS X, so if you upgraded to OS X 10.7 or later, you must reinstall  the original OS, either from the installation media, if applicable, or by booting into Internet Recovery (option-command-R at the startup chime.) If you installed from discs or a read-only USB key, deliver those to the new owner.
    The new owner will have to repurchase the software, if need be, under his or her Apple ID. If you ever updated the bundled iLife applications (Garage Band, iMovie, and iPhoto) through the App Store, you can't transfer them either.
    Remove the machine from your list of registered products. If it's still covered by an AppleCare Protection Plan, transfer the coverage to the new owner by following the instructions in the AppleCare Terms and Conditions (under the heading "Transfer of Plan.")

  • Problems with my external USB 3.0 (Toshiba) hard drive and Macbook Air 2012

    I can't seem to get any help on this from Apple and I am tired of ti I have a new Macbook Air 2012 model and have several Toshiba external USB 3.0 drives. I did the Mountain Lion App Store 10.8.2 update and all of a sudden non of my drives are mountable or accessible. I've been in IT 16 years and have never seen anything like this. The drives are physically fine and I can see the mapped partitions on a Windows 7 machine just fine and even use HFS Explorer to view the directory structures. The data on these drives is extremely important to not only me, but also the DoD who I am working with on a major project. Now I can't get to my documents to edit them or pull down the virtual machines I setup for my labs.
    I've done all sorts of research and googled myself to death. I even foudn the "missing because Apple pulled" 2.0 update to try and fix this issue. Whatever was done with ML 10.8.2 on these notebooks renders the USB ports useless. Does anyone have a solution to getting these drives to mount?

    I have the same issue. 
    I have two disks HDTC720XK3C1 (Portable Toshiba Hard Disk, USB 3.0 + 2.0, 2.0 TB). Purchased on the same date and same model.  One inexplicably stopped working.  
    When i connect the drive, the systems show an message that say:
    "You need format the drive <x> before can you use it
    Do you want to format it" 
    I attach the two pictures with the screen error and disk  managment.
    Question for the group:  These devices seem not very reliable ? this type of error the warranty covers?  Sugestions ? 
    i think, that a backup tool should be secure. This is the 7th time I use it and the data is completely lost. Opinions?

  • Is it worthwhile to load windows 7 onto my MacBook Air? Will it slow down my computer?

    Is it worthwhile to load windows 7 onto my MacBook Air? Will it slow down my computer? What might be the benefits of having windows and mavericks as two different operating systems side by side?

    Check out this article first. It deals with BootCamp vs Parallels Desktop but there are two other products: VMWare Fusion and VirtualBox that offer the same basic features as Parallels. So your first decision is which you prefer. As I said, I chose virtualization: Parallels Desktop in particular.
    You need a full retail version of Windows - If you live in the States try New Egg for the best price. This is what I bought. You'll need it whether you choose BootCamp or virtualization. Note that Win7 apparently isn't available via download from Microsoft any longer, only Win8 so you'll need access to an external optical drive or use remote dvd sharing with your Windows computer. I've not tried installing Windows using remote DVD sharing but I have installed other software that way so I'd expect it to work if you choose virtualization. If you choose BootCamp you'll need access to an external optical drive or create an ISO image of Windows on a large flash disk.

  • Does the MacBook Air 2012 supports SDXC Cards?

    Does the MacBook Air 2012 supports SDXC Cards?
    Thx

    Hi! How are you? The reason why I'm here is to find out more about SDXC support/compatibility info on the macbook air 2012 and how to fix this nagging issue if it's fixable.
    I had just bought a Sandisk extreme pro 64GB rated at 95mb/s for my Nikon DSLR. Unfortunately, MBA struggles to detect or mount my card, after a few sweats, it would mount, but then very slow to process and preview the images as "Thumbnail preview". Then, after a few more sweats, you can scroll through the thumbnails smoothly.
    Streaming HD videos straight from the SD Slot is butcher chopping the beef. Video lags, stutters, chops, in otherwords, USELESS and a pain in the neck. So you just want to copy all the files to your macbook, and play from there. Copying files from SDXC to my macbook takes forever; writing is also another issue that take much more than forever!
    I have a top of the line macbook air 2012 (i7, 8GB, 512) and I always thought it's a versatile reliable computer but now I'm very disappointed. On the other hand, doing the same things on my macbook pro 2010 is seamless. I also tested on my windows 8 desktop to be flawless as well.
    Therefore, the memory card is not the problem. It's macbook air's sd slot that's a failure. I never thought spending $2,199 for a super computer would make me stress like this. In addition, the magsafe 2 is another failure in design. It always disconnects just by moving my macbook air from one spot of the table to another. Having it charged while on my lap gets on my nerves when it keeps getting disconnected! I hate Apple for doing this. If only there was a Windows notebook that surpasses Apple's design, I would never EVER buy Apple products EVER again.

  • I am trying to install windows 8 at my macbook air boot camp

    I am trying to install windows 8 at my macbook air boot camp but Boot Camp Assistant i showing an error that the disk cannot be portioned because some files cannot be moved. Back up the disc and use disk utility to format it was a single Mac OS Extended (journaled) volume. Restore your information to the disk and try using Boot Camp Assistant Again.
    I had already installed teh first time Windows on my MacBook Air and Mac Book Pro. Actually I had more issues to install on the pro than Air.
    But my Macbook Air had an issue on November 2013, 3 weeks after buying it and Apple gave me a new MacBook Air but they only transferred the information on my mac and the windows partion was lost according to them, they could copy it in to my new MacBook Air. Now that I am trying to install my windows I can not access to the aprtion section and get the error message from above.
    What can I do to to install it? I am using a 32GB USB and OEM Windows 8 at USB External Drive. The same I used before. I dont know understand what changed if I did it before?
    Please advise..

    I think there's some remmants left over from when Apple transferred stuff over. We can try a quick fix, but if that doesn't work, I think the only option is to clean install OSX and then install Windows.
    open disk utility, confirm that you only have 1 partition (mac journaled)
    restart and PRAM reset
    open disk utility and repair permissions twice
    restart boot camp assistant
    Does it work?
    If not, I would boot holding command+R, choose disk utility from the menu and completely erase your HD (formatting it as mac journaled again). Then, install OSX on this HD. Once OSX is installed, don't copy your files over from the backup yet. Instead, start boot camp assistant and see if you can get Windows installed. You can copy back your other files after we get Windows installed.

  • HT3986 How do I download Windows 7 to my Macbook Air?

    I need to download Windows 7 to my MacBook Air and was wondering where I would find a version that could be downloaded via the Internet.

    Welcome to the Apple Support Communities
    Before the Windows 8 release, Windows 7 was available in the Microsoft Store as a download and you could get it there. Unfortunately, now it's not being sold anymore as a download, so you have to buy Windows 7 on a DVD in Amazon or eBay, and use an external optical drive to install Windows on the MacBook Air

  • HT5628 why cant i install windows 8 on a macbook air 13-inch, Late 2010?

    why cant i install windows 8 on a macbook air 13-inch, Late 2010?

    Welcome to the Apple Support Communities
    You can install Windows 8 on your computer because it can run Windows 8, but you can't install the Windows support software that makes Windows run properly, so probably things like the Wi-Fi card, the sound and the graphic card may not work without these drivers.
    That's just an Apple restriction. Apple has decided to give Windows 8 support to the most recent Macs, leaving old Macs with Windows 7. Unfortunately, to run Windows 8 properly, the only option is to install it on a virtual machine. Apart from that, if you want to install Windows 7 with Boot Camp, you can do it

  • I have a new Macbook Air 2012, Apple TV 2 and I have tried wired and wireless connections both result in stuttering during video airplay to the ATV2.

    I have a new Macbook Air 2012, Apple TV 2 and I have tried wired and wireless connections both still result in stuttering during video airplay to the ATV2.
    I have even bought a new Airport Extreme Router just to confirm it is not the router and it still didn't help.
    I have brought all items in the same room with wired connections and still same issue.
    I was thinking maybe ATV 3 might help since it has 2 wifi antennas and faster processor.
    Have tried everything I could think of.
    This was one of the main reasons I bought a Macbook Air for this airplay feature. Very frustrated.
    Any thoughts; any other suggestions would be greatly appreciated.
    Thanks

    Thanks for the suggestion.
    I also disabled Norton Firewall and restarted the Air and Now I'm able to use Air Play.
    I know that the Apple remedy said that to do that in the support article, but I totally forgot I had that enabled..
    It actually works. I can even stream to the Apple TV now through my MacBook Air.
    BTW, Go into setting under the ATV, and click on update...you'll see that there was another update avaialble for the last gen of ATV...
    It does have to restart twice..I guess once to download and and nother to apply.
