The minimum number of partitions needed to dual boot windows xp and windows vista is actually 2, one for each operating system. However, if your computer was bought and it already had one of those two systems preinstalled and with it a separate windows recovery partition as well as a system reserved partition, then your minimum in that case would be 4 priamry partitions (which also happens to be the maximum allowed if you are using strictly primary partitions. One way to have more than 4 primary partitions is to have one of those partitions become an extended partition which can in turn have as many partitions as you need.
I hope that wasn't too confusing
Two. One for Windows XP and one for Windows Vista.

DOS can support multiple partitions as like windows but the maximum partition will be of 2 GB maximum, as DOS supports FAT 16..
A technician is attempting to create multiple partitions on a hard disk. This will allow for storing the operating system and data files on separate partitions. What is the maximum number of primary partitions per hard drive that is supported by Windows XP?
Windows 1.0, 2.0, 3.0, 3.1, 95, 98, and ME can support a maximum of 26 drives or logical partitions. Windows NT 3.1, 3.5, 3.51, 4, 2000, XP, 2003, Vista, 2008, and 7 can support several thousand drives / partitions in a system.
A single MBR-Style disk can contain a maximum of four primary partitions.
Wen you are talking about Partitions, you aren't talking about Windows, you are talking about the HDD(Hard Drive Disk). this is a "thing" on the HDD, not Windows. theoretically, you can have as many Partitions as you would like, provided you have the memory for it. Lets say you make a partition that is 5GB, and you install Windows XP on that Partition. Also, your HDD is 57GB. Windows cannot use any memory outside of that Partition. This means that, although you have a 57GB HDD, Windows can only use the 5GB you assigned it. A Partition is sort of like an HDD on an HDD. It can become very confusing. I hope tis helps.
Four partitions.

Assuming one of them is an extended partition on an MS-DOS partition table: Eight. If the partitions are all primary partitions: Four.

Typically you can only have 4 primary partitions per hard drive if you are using the MBR partition layout scheme. If you need more partitions than the maximum allowed (4), then there is a way to get many more partitions with only one hard drive.By creating an extended partition you can have as many logical partitions as you need within that extended partition, thus you can have more than only four partitions. You can have 3 primary partitions and one extended partition (for a total of 4), and inside the extended partition you can have as many logical partitions as you need.The one thing to keep in mind is that any type of Windows Operating System needs to be installed in a primary partition, otherwise you cannot boot into it. Windows XP in particular, needs to be installed in the first primary partition. For everything else, you can create as many logical partitions as you want inside the extended partition.
