I am trying to uninstall Ubuntu by following these directions, but I have a question. Which partitions do I delete? I am assuming it is the three blank ones, but why would Ubuntu have three partitions? So I just wanted to make sure.
Unless you have installed a third operating system, these are your Ubuntu partitions:
Right-click to remove these partitions one-by-one, and then right-click the first (C:) to extend it across the unallocated space OR create a new partition in there.
diskpart tool to get more info without booting a LiveCDYou can get some more information on the two 8 GB partitions from within Windows by using the diskpart command:
diskpart, you will get a prompt.select disk 0, and then select part 3Type detail part, and you should get something like this:
Partition 3
Type : 82
Hidden: Yes
Active: No
Offset in Bytes: 442499072000
Type 82 is swap, while type 83 is regular Linux (ext4, etc.). Do the same for the fourth partition, with select part 4. If either of those are NOT type 82/83, you should boot a LiveCD and investigate further with gParted as Eliah Kagan's answer recommends.
