Right, any reason for this?

The Free edition of PW is limited trialware. Some of the more advanced features will not be available. The bootable CD (ISO) has all features enabled.

It is not advisable to alter the Windows partition while Windows is running. The bootable CD runs on its own (Linux IIRC).

Awesome, I'll give it a shot and post back the results. Thanks all. One more question... How many primary partitions can I make in PW? I can't seem to make another from Disk Management.

Hi JaidynM,

Usually Windows 7's disk management tool allows you to create 3 primary partitions only with an extended partition and logical drives.

As you already have three primary partitions (2 for windows 7 and one for windows 8) Windows 7's disk management program will not allow you to create another primary partition, but only an extended partition and logical drives inside. So you can not create another primary partition for Ubuntu.

You have to use a third party program like Easeus Partition Master or Minitool Partition Wizard boot CD or any similar program to create a fourth primary partiton from the unallocated space (50GB) left.

As an example, I have used Easeus Partition Master program and created a fourth primary partition on a virtual machine's second HDD. (See attached images).

The only caveat is that you need to use the complete unallocated space for this fourth primary partition. Otherwise any leftover unallocated space will go waste and can not be reclaimed.

If you dropped the idea of installing Ubuntu on this machine and use this free space for Windows 7's C: drive - Easeus Partition Master's Move partition command can move a partition without extend and shrinking the partition. The windows 8 partition can be moved to end of the disk with this command. This will move the free space between C: drive of Win 7 and Windows 8.

Now you can resize the Windows 7's C: drive to take this space. You don't have to extend and shrink Windows 8 partition to achieve this.

Normally any hard disk will allow 4 primary partitions or 3 primary partitions and 1 extended partition with multiple logical drives. But you can have only one active partition which has to be a primary partition.
