You have two choices, a single Operating System (OS) or a multi- boot system. An additional hard drive may be used for Linux or an. Linux. may also reside as the only operating system on the computer as.

Using a separate drive for. Linux is the easiest and the preferred multi- boot configuration because it allows the original Windows drive to remain intact. In order to boot the Linux drive, insert the floppy or CD with the Linux boot loader (Lilo or Grub) and boot from the floppy or CD.

The Linux boot loader can be installed on the MBR of the floppy. See /dosutils/fipsdocs. This tool is. unsupported. Partition Magic would be a wiser choice for those.

For dual boot installations, MS/Windows can be. Microsoft installer to repartition the drive. It's that easy. Upon boot- up, the NT loader. Grub to boot Linux.
