Another way to achieve XP, Vista dual system coexistence

This paper is another way to achieve the coexistence of XP, Vista dual system, in fact, is very reasonable. I suggest you learn from it, and go directly to the topic of this article.
First, the dual system introduced

1,
# characteristics of this dual system XP, Vista is independent, independently of each other, each mounted on a primary partition start
# The process is, bois--mbr--ntldr-- here choose to boot to XP or Vista, that is to say, use XP to start Vista through boot.ini, Vista is too troublesome to start XP, say goodbye to bootmgr.
2, disk tool 1: backup mbr software
DOS debug, XP, Vista winhex 13.7 SR7, Linux dd (save mbr has many tools)
3, disk tools 2: Partitioning Tools
It is possible to change the partitioning software of the active partition (there are many). In fact, in the disk management of XP and Vista, you can change the active partition, right click on the primary partition--mark the disk partition as active.





































One installs XP, one installs Vista, it is best to put the XP partition in front, because the multi(0)disk(0)rdisk(0)partition(1) in boot.ini records the partition order.
Narrative according to the program
Third, install the system
a. First install XP and then install Vista
1, activate the first partition, install XP

3, activate the second primary partition, then install Vista
4, save mbr as mbr.2
5, activate the first partition, boot into XP

C:\\MBR.2="Microsoft Windows Vista Ultimate"
b. Install Vista first and then install XP
1. Activate the second Partition, install Vista
2. Save mbr as mbr.2
3. Activate the first primary partition, then install XP
4. Save mbr as m Br.1
5, boot into XP
6, copy the saved mbr2 to the root directory of the XP partition, add a line in the boot.ini
C:\\MBR.2="Microsoft Windows Vista Ultimate "
Interested friends can compare mbr.1 and mbr.2
IV. Cancel dual system
a. To cancel XP system, activate the second primary partition, then process the first master Partition
b. To cancel the Vista system, delete the boot menu, and then process the second partition
Note: If you use pq partition, XP boot.ini boot Vista may have problems, please use XP, Vista's self Repartition with the partitioning tool. Recommend spfdisk.
