"You must have at least 10GB of free space available" when I have 114GB free

Long time no see Apple Support,

I've just spent this morning doing some much needed maintenance to my Macbook Pro. I've been deleteing tons of files and I am getting ready to do my first battery calibration in 2 years! I was also planning on setting up Windows 7 again since my work needs it and also I want to play some games.

However, upon opening Boot Camp Assistant it tells me I do not have enough space and gives me the "You must have at least 10GB of free space available" message. Which is wrong because I have 114GB free on my Macintosh HD.

I've spent some time googling this but a lot the people having this issue had little space left (20GB) but that is not the case for me...

Any ideas?

Thanks,

Ewan

MacBook Pro, Mac OS X (10.6.7), 15-inch, 4GB DDR3 RAM

Why don't you post the entire error message, you left something out.

I simply get:

The Startup Disk does not have enough space to be partitoned

You must have at least 10GB of free space available

Which is a lie because I clearly have 114GB free as said by Finder.

Are you sure the message does not mention erasing your drive and restoring it?

Repair your hard drive and try again.

Ha ha, I've already gone into Recovery HD and repaired the disk and fixed the permissions. I've also ran a file rebuild with DiskWarrior and I am currently trying iDefrag.

Why iDefrag, do you suspect that your disk is fragmented?

iDefrag generally fails to fix that.

Backup your disk, erase and restore it from the backup, try again.

If in doubt on the Apple support forums just give up and format, aha. Meh, I stick with refind and do it manually.

Do you have something to say or are you just playing the child for fun?

Excuse me? I thought people were meant to be helpful here and not just randomly criticise - hense the name 'Apple Support Communities'. I've solved my problem without formating by simplying manually partitioning and using rEFInd.

I've said what I have to say and no, I'm not playing like a child? If you don't like my solution then don't say anything? You're the same in every reply - assume everything they are doing is wrong.

There are some Mac OS files on the last 10 Gbytes you want to place Bootcamp. Defragmenting is a good idea but it's also bad because the disk is under pressure for a long time. Better having an updated backup, reinitialize the HD and restore the Mac OS. No Mac OS file should into the 114 Gbyte free space.

Please note: normally, those files are moved by Bootcamp Assistant prior to create the BC patition but sometimes it fails.

Cheers
