How do I install Linux along with Windows 98?

Both operating systems offer the ability to log in as a limited-rights user. This prevents the currently logged in user from being able to modify vital settings and potentially ruin their OS installation. However, Linux proponents argue that since many programs available for Windows require administrative rights to use and install, many users run as the administrative user at all times, allowing malware run under their account to manipulate vital system settings. Further, they point out that most Linux distributions make it difficult to log in as the root user, and require a conscious effort to do so. In response, Windows users point out that it is not a flaw of the operating system that causes users to always use the administrator account, but rather poorly designed programs.Then, some people argue that the abundance of software designed to run with administrative privileges is connected to the habits and tools developed when home versions of Windows didn't support permissions (prior to Windows XP).
