New to Bootcamp Need help

[Ant2369]

I'm trying to install Windows 7 onto my new iMac and its giving me an error. im brand new to bootcamp can anyone help please

The disk cannot be partitioned because some files cannot be moved.
Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again.

I've verified in Disk Utility it is already formatted that way..

thanks for any help

It's a common problem unfortunately. See an older thread about it: https://forums.macrumors.com/threads/191729/

How full is your disk currently?

You could try to partition and install manually when booted from another boot device. Do you have an external HDD or your OS X install DVD?

NOTE: I have no experience with Fusion drive and haven't been keeping up to date with any changes that might entail.

You really want to resize the partitions when nothing else is running, because open files tend to lead to this particular error. This is why running disk utility to resize the partition when booted from another device sometimes works when it doesn't if you are booted to the drive you want to resize.
