Description: Their programming guide If you are a computer users believe you must have installed the operating system, when you use an operating system for a long time, you could install a new operating system, but you often want to keep your current operating system. When you have a windows98, for example, you can then install windows2K or Windows xp, it is because Windows NTloader can know earlier than their operating system, so can give you keep the previous operating system. But what if you now have a Windows 2k or Windows xp that you want to install on your hard disk with Windows 98 or even some nostalgic people who want to install a DOS6.22 on it? You tend to use third-party software, such as V communications, inc's System Commander series, PowerQuest corpora BootMagic, and so on. These software sets the hard disk partition to two or more than two primary partitions, (which is what we call the double "C", or "C" more plate), to install different operating systems in different primary partitions, by activating different partition to implement multiple guide, its advantage is the safe and stable, once an operating system paralysis, a bit does not affect other operating systems, personally think that is worth to recommend.
This article is not a multiple operating systems implementation experience, so the use of third-party software such as the BootMagic I wouldn't waste of space to introduce, I want to make a analysis of such software is the implementation of the principle.
