I'm trying to figure out how to install BT 4 R1 on my Macbookpro using VMware Fusion.
I've downloaded the VMware image of BT4 R1 and launched it in VMware Fusion. Then I've started the install.sh script. I've already installed plenty of linux distros so I know how it works but here I get an error I've never had :

Failed to unmount partitions
The installer needs to commit changes to partition tables, but cannot do so because partitions on the following mount points could not be unmounted:


Please close any applications using these mount points.

Would you like the installer to try to unmount these partitions again?
Then I tryied to pre-allocate my VMware space disk but it was unsuccessful. I still get this freakin' error message...

Anyone's an idea ?

Thanks a lot !

PS : I'm using VMware 3.0.1 on OSX Snow Leopard 10.6.2
