Could not alllocate partitions installing F14 with Win7

[Bipster]

Hello All -

I'm trying to dual boot F14 along side of Win7 and I'm running into partitioning errors -

"Could not allocate requested partitions: not enough free space on disks"

I used the Win7 Disk Management to shrink the C:\ drive by 100G, and the Disk Utility in F14 shows the unallocated space.

Here is what the current layout looks like:
--210Mb bootable (sda1)
--168Gb (sda2) --Win7
--105Gb unallocated -- Future home to F14
--31Gb extended (sda 3) -- not sure what this is used for
--31Gb (sda 5) -- Lenovo drivers
--16Gb (sda 4) -- Lenovo restore

Am I running into the partition limit I have been reading about?
If so, is there a way to get around this? I really don't want to delete the partitions yet.

If it's not the partition limit, what else could it be?

Thanks Bispter

Yes, you have already used the four possible primary partitions (sda1-sda4). The only way to create additional partitions is to move the unallocated space inside the extended partition (sda3). Then you can create logical partitions (sda6-...)

Thanks. Can I use the Disk Manager from Win7 to do this? And when I go to install F14, I just point it to the extended region?

Sorry for the questions, I never did this before, and really don't want to screw it up, it's a brand new laptop
