    I was trying to make another partition on my Macbook Pro using Disk Utilities. After 3 hours or so the progressbar wasn't even half way so I closed the program. Now the problem is that I lost 60GB of free space that the partition required, but the partition itself is not made. It doesn't come up anywhere in Disk Utilities.

    Is there any way to get my 60GB space back, or am I kind of screwed unless I do a clean install ?

    Are you on Lion or Mountain Lion? If you are, try a command-r boot to recovery and run Disk Utility from there and do a repair disk.

    If that does not work, run the command below in Terminal and post up the output.

    diskutil cs list

    I believe I'm running on Snow Leopard.
    A command-r boot gives me a rEFIt interface. I synched my partitions (the only option I could select really, except start up my main partition). From the looks of it I had 3 partitions in the MR partition table, 1 of them with a start LBA (no idea what that is) of 1, so I think that's the partition that failed. But still Disk Ut only sees 1 partition.

    Partition Inspector gives the following report
    *** Report for internal hard disk ***
    Current GPT partition table:
     #      Start LBA      End LBA  Type
     1             40       409639  EFI System (FAT)
     2         409640    487127591  Mac OS X HFS+
     3      487127592    488397127  Mac OS X Boot
    Current MBR partition table:
     # A    Start LBA      End LBA  Type
     1              1    488397167  ee  EFI Protective
    MBR contents:
     Boot Code: Unknown, but bootable
    Partition at LBA 40:
     Boot Code: None (Non-system disk message)
     File System: FAT32
     Listed in GPT as partition 1, type EFI System (FAT)
    Partition at LBA 409640:
     Boot Code: None
     File System: HFS Extended (HFS+)
     Listed in GPT as partition 2, type Mac OS X HFS+
    Partition at LBA 487127592:
     Boot Code: None
     File System: HFS Extended (HFS+)
     Listed in GPT as partition 3, type Mac OS X Boot
    Terminal gives back "No CoreStorage logical volume groups found" which I don't know what it means exactly, but it sounds kind of bad.

    ok I fixed it, turned out I just did the recovery on a wrong element ^_^
    This is off topic, but is it normal that making a partition for Windows takes hours and hours, or is that the fault of me assigning all the free space I had to that partition by accident ?

    Thanks for your reply
