Windows 7 and Ubuntu 10.10 dual-boot - can not create a new partition

[Simple Nok]

I've shrunk my Windows partition to ~200GB and made ~100GB of free space for Ubuntu BUT .. it doesn't allow me to create a new partition there as I already have 4 primary ones.

Since all of the given partitions ( including Recovery and Tools ) can not be touched ( removed ), I have no idea on how to solve this ..

Anyone ?

You do have to backup & delete one partition, so you can then create an extended partition to hold the logicals that Ubuntu needs.

Good advice on how to handle all four primary partitions used. - srs5694
