Can I have Windows NT windows 95 and Linux together in my computer?

Security has been a hot topic with Windows for many years, and even Microsoft itself has been the victim of security breaches. Due in some part to the widespread usage of Windows on personal computers, as well as a number of technical reasons there is reportedly a five-fold greater amount of malware for Windows than other operating systems such as GNU/Linux, Unix, Mac OS X, and FreeBSD. Windows was originally designed for ease-of-use on a single-user PC without a network connection, and did not have security features built in from the outset. Windows NT and its successors are designed for security (including on a network) and multi-user PCs, but was not designed for Internet security in mind as much since, when it was first developed, the Internet was less important. Combined with occasionally flawed code (such as buffer overflows), Windows is a frequent target of worms and virus writers. Furthermore, until Windows Server 2003 most versions of even Windows NT were shipped with important security features disabled by default, and vulnerable (albeit useful) system services enabled by default. In June 2005, Bruce Schneier's Counterpane Internet Security reported that it had seen over 1,000 new viruses and worms in the previous six months.
