    So I was making a small like 2GB partition to share files between my OSX Lion and Windows 7 partitions.
    After I did that, I transferred some files over to that partition, then tried booting into Windows.
    So, I do the normal hold ALT when I turn it on, and all I see is my OSX Lion startup and the OSX Recovery option. My Windows is missing :(

    So I go into OSX to figure out what's wrong, under Startup disks it still has the option to boot into my Bootcamp and when I do the Restart into.. option is restarts and sits on a blank white screen.

    I can still see my BOOTCAMP partition in finder, all my files are still there.
    So I was thinking if I reverse everything I did it would work, so I deleted the ~2GB partition and extended my Mac OSX partition back to where it was to fill the empty space. Still no Windows, so can someone help?
    I'm running lion.

    With creating the third partition, you probably "destroyed" the option to boot into Windows, as you probably fracked the partition table. I can't explain that any further, as my knowledge is limited in this case, but I have seen some threads, where similar things happened after creating a third partition. Maybe balamw can add some info.


    Maybe have a look at Advanced Search to find similar threads:

    You probably have to delete your Windows partition via Boot Camp Assistant, not via Disk Utility (as DU uses a "different" method than BCA to create and delete a partition when using Windows too).
    Or you can take a look at gParted, a Linux tool to repair to repair corrupt partition tables. It helped me once.

    For exchanging files between Windows and Mac OS X, look at the following guide:


    Overview of the four major file systems (called "Formats" in Mac OS X) used on Windows and Mac OS X, compiled by GGJstudios. You can use Disk Utility to format any HDD to your liking.

    Any external hard drive will work with PCs or Macs, as long as the connectors are there (Firewire, USB, etc.) It doesn't matter how the drive is formatted out of the box, since you can re-format any way you like. Formatting can be done with the Mac OS X Disk Utility, found in the /Applications/Utilities folder. Here are your formatting options:

    FAT32 (File Allocation Table)
    • Read/Write FAT32 from both native Windows and native Mac OS X.
      [*]Maximum file size: 4GB.
    • Maximum volume size: 2TB
    • You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.
    NTFS (Windows NT File System)
    • Read/Write NTFS from native Windows.
    • Read only NTFS from native Mac OS X
      [*]To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
      • For Mac OS X 10.4 or later (32 or 64-bit), install Paragon (approx $20) (Best Choice for Lion)
      • For 32-bit Mac OS X, install NTFS-3G for Mac OS X (free) (does not work in 64-bit mode)
      • For 64-bit Snow Leopard, read this: MacFUSE for 64-bit Snow Leopard
      • Some have reported problems using Tuxera (approx $36).
      • Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
    • AirPort Extreme (802.11n) and Time Capsule do not support NTFS
    • Maximum file size: 16 TB
    • Maximum volume size: 256TB
    • You can use this format if you routinely share a drive with multiple Windows systems.
    HFS+ (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive)
    • Read/Write HFS+ from native Mac OS X
    • Required for Time Machine or Carbon Copy Cloner or SuperDuper! backups of Mac internal hard drive.
      [*]To Read/Write HFS+ from Windows, Install MacDrive
      [*]To Read HFS+ (but not Write) from Windows, Install HFSExplorer
    • Maximum file size: 8EiB
    • Maximum volume size: 8EiB
    • You can use this format if you only use the drive with Mac OS X, or use it for backups of your Mac OS X internal drive, or if you only share it with one Windows PC (with MacDrive installed on the PC)
    exFAT (FAT64)
    • Supported in Mac OS X only in 10.6.5 or later.
    • Not all Windows versions support exFAT. See disadvantages.
    • exFAT (Extended File Allocation Table)
    • AirPort Extreme (802.11n) and Time Capsule do not support exFAT
    • Maximum file size: 16 EiB
    • Maximum volume size: 64 ZiB
    • You can use this format if it is supported by all computers with which you intend to share the drive. See "disadvantages" for details.

    And btw, bumping in such a short amount of time is a bit frowned upon.

    Well I gave up and used WinClone to copy the partition, since I didn't have much on it. After it finished I used Boot Camp Assistant to delete the existing BOOTCAMP partition.
    I'm trying to create a partition using Boot Camp Assistant so I can restore the image to it, but when I choose how much disk space and hit 'Install'.
    After like 20 seconds it says 'The installer disk could not be found.'

    So what do I do now? I thought I could just create a partition using Boot Camp Assistant, which is what I think I did before when I initially installed Windows 7.

    So any help is appreciated! Thanks :)

    you have to reinstall windows before you can restore the image to it. as image is not bootable.also you cannot restore image to partition smaller than one it came from
