Windows must be booted from the first hard disk.

directories with a back slash.

11. linux
Linux, on the hand, technically is a kernel. A
kernel is the central component of many
operating systems. The Linux kernel was first
released on 5 October 1991 by Linus Torvalds.
However, the term Linux has come to refer to
the full fledged operating systems built with the
Linux kernel. These should be correctly called as
Linux distributions or Linux-based operating
systems. Some of the popular Linux distributions
include Ubuntu, Fedora, SuSE and Debian.
