3.5. Installing from CD-ROM

	Note
	If you already have another operating system installed and want to create a dual boot system so that you can use both Red Hat Linux and the other operating system, read Appendix G Configuring a Dual-Boot System for details.

To install Red Hat Linux from a CD-ROM, choose the CD-ROM option from the boot loader screen and select OK. When prompted, insert the Red Hat Linux CD into your CD-ROM drive (if you did not boot from the CD). Once the CD is in the CD-ROM drive, select OK, and press [Enter].

The installation program will then probe your system and attempt to identify your CD-ROM drive. It will start by looking for an IDE (also known as an ATAPI) CD-ROM drive. If found, you will continue to the next stage of the installation process (see Section 3.12 Language Selection).

	Note
	To abort the installation process at this time, reboot your machine and then eject the boot diskette or CD-ROM. You can safely cancel the installation at any point before the About to Install screen. See Section 3.28 Preparing to Install for more information.

If your CD-ROM drive is not detected, and it is a SCSI CD-ROM, you can manually select the SCSI CD-ROM type when prompted.

Select SCSI if your CD-ROM drive is attached to a supported SCSI adapter; the installation program will then ask you to choose a SCSI driver. Choose the driver that most closely resembles your adapter. You may specify options for the driver if necessary; however, most drivers will detect your SCSI adapter automatically.

	Tip
	A partial list of optional parameters for CD-ROM drives can be found in the Red Hat Linux Reference Guide, in the General Parameters and Modules appendix.
