I want to triple boot Windows 7, Backtrack, and Ubuntu.
Windows and Backtrack are already installed.
The problem is that both of them take 4 partitions: 3 for Windows, and 1 for Backtrack.
When I try to make another partition, it says I can't have over 4.
How can I install Ubuntu with this problem?
Note:
The 3 Windows partitions are PQSERVICE, SYSTEM RESERVED, and eMachines. I don't really know if I can delete one.

Hard drives are indeed limited to 4 primary partitions. Luckily for us multi-booters, if you create an extended partition, it can serve as a container for additional primary partitions. The problem is, since an extended partition counts as a primary partition, if you've already hit the limit, you would need to remove a partition and recreate it within a new extended partition. Since you said that your partition manager complained, it looks like you've hit that limit. So, my best advice is to see if you can safely delete and recreate one of your partitions. Your best option may be to do so with Backtrack's partition. If you have a spare hard drive, you could probably clone that partition to it and restore it back onto a new partition within your extended partition.
Unfortunately, that's the only solution I know of. More experienced guys can probably give some more insight, but hopefully this will prove helpful at least for now. Best of luck to you!
