Re: Partitioning and Dual Boot
I understand your confusion. You have some good answers above. Post #4 is very important! You do have 4 primary partitions on Disk0 (partitions are primary or extended or logical and it would say if they were the latter 2 types)and cannot install Ubuntu without sorting that out. My suggestion is:
Using Win7, delete the Data (D) partition. (Its empty and this gives you unused space and only 3 primary partitions left)
Using Win 7, shrink the windows OS C: partition to say 100GB. Its already got 56GB in it, so 50 isn't enough!)
Now you can use Ubuntu install disk to create an extended partition in the empty space. An extended partition is like a container holding Logical partitions. (In itself an extended partition does not hold data, just partitions. Its like the outer box you get when ordering from Amazon - nothing in it but other boxes)Within the extended partition you can create all the new partitions you want, using the "something else" option as suggested by others above.
I would physically unplug your external drives while doing any of this so you can't accidentally format over your data!
I'm not sure why you can't see the partitions from the Ubuntu disk. Is the md5 sum OK? Have you tried looking at it with a gparted live disk?
Hope this helps a little.
