JL@Technicolor Level 1 Level 1

I'm trying to install Windows 7 through Boot Camp.  I get all the way to installing Windows and it fails because it needs an NTFS-formatted drive.  I don't see anywhere in the BootCamp setup assistant that allows me to make that (or any, for that matter) choice about how the Boot Camp partition should be formatted.  How do i do this?

    It tells you. It is spelled out. There is a button below the box where you choose where to install. Click on Advanced Options. It tells you in the manual pdf guide. Somewhere right after page 21.

    Also, when Windows 7 Install is telling you that it can't install on a FAT partition, there's an option to format it with NTFS without having to go back to Boot Camp and re-do it from scratch.


    In the window that gives you a list of partitions and asks you where to install, select the bootcamp / FAT partition you want to use, then click "Drive options (advanced)" on the bottom-right. Then select "Format" to format it for NTFS.

    I'm having the same problem


    Bootcamp assistant formatted the drive, but windows 7 won't install


    I formatted the partition, deleted,bcreated and reformatted and it still needs NTFS.


    Spent 40 minutes waiting on Support, then gave up after the Tech tried to find me a supervisor as she was STUMPED too

    Then..... you didn't read what to do.


    When you get to where you choose "BOOTCAMP" (page 22 in pdf manual), click on the button below (Advanced Options) where you convert/format MSDOS to NTFS.


    It is easy, it is what everyone does, and has been part of install process since Vista and since Jan 2008 at least (or the release of Leopard and Boot Camp 2.0).

    But I did that!


    The Advanced option was Format, no Convert



    I formatted. No luck


    I deleted, created and formatted.


    Still no luck


    But shouldnt Bootcamp make an NTFS automatically?


    I'm on Lion on new Mac mini. Is the Bootcamp Assistant different from the earlier version?  Can I downgrade?

  • Kid Dynamic Level 1 Level 1

    Re-reading your previous post, Hatter, it turns out I was basically repeating what you just said. Albeit with a graphical guide. Sorry about that.


    Condie, just do the thing that Hatter and I mentioned you need to do. That will fix it.

  • Kid Dynamic Level 1 Level 1

    Oh, really?


    Yes, there's no "Convert". You can only re-format as NTFS.


    After you've formatted, what happens? Does it still say the drive can't be used? Are you selecting the BOOTCAMP drive? Are you hitting "Next"? Is there an error that appears?

  • condie1 Level 1 Level 1

    Well, you DON'T just convert/format MSDOS to NTFS from Advanced


    That is not an option, as I re-read it


    You click NEXT and the installer should format it


    Trying again. Will keep you posted

  • condie1 Level 1 Level 1



    Replied too fast


    There was a prompt to format from Advanced. And I did


    Then I clicked Next


    Ang get message "setup was unable to create a new system partitition."


    Any ideas?

  • Kid Dynamic Level 1 Level 1

    Wow, yeah, that's not supposed to happen.


    Condie, after doing a little research (Searched google for "setup was unable to create a new system partitition.") there could be a couple solutions.


    Are you by chance installing Windows from a USB drive (not DVD) as the install disk? Or, do you have other external drives attached? Try pulling them all out, and trying again. That info was in here:

    And: which suggests that maybe you don't have to unplug the USB drive if you're using it to install Windows, just everything else.


    Or, maybe you used a USB drive to copy the support files in Boot Camp Assistant, and left it plugged in? If so, try unplugging it and trying again.


    If none of these apply to you, you could try going into the Windows command window by hitting Shift-F10, then doing the following: m?page=4


    Hope this helps!

    Thanks for the tips


    Will keep you posted


    I'm tempted to delete the Mac partitions in the Windows install


    Would that preclude a Recovery?

  • Kid Dynamic Level 1 Level 1

    If you delete the Mac partitions, you will destroy your Mac OSX installation and all the data there. You'd need to use Time Machine or similar backup to restore. Honestly, you shouldn't have to do this, it doesn't make any sense. :-/ Let us know if the unplugging USB drives thing works...

  • condie1 Level 1 Level 1

    Got it, finally, with a couple of mis-steps :-)


    Extra USBs seems to have been the problem indeed!


    I unchecked the USB option the first time, hoping to boot from external DVD.  But Bootcamp still demanded a USB that it couldn't  fiind.


    Enabled just one USB the second time, and Windows installed off the DVD!


    As long as it works . . .


    Was delighted with installing the Support stuff on Windows, all those drivers just zapping in, plus the Taskbar bootcamp/Bluetooth.


    This is better than most PCs!!!!!


    OFF-topic, but while I've got you: Could I have used 64-bit? I can use only 2G of my 8G RAM.




    THANK YOU!!!

    Just wondered if you ever solved YOUR problem?
