Installing RHEL off non-bootable DVD & External DVD ROm

[heyyunus]

Hi,

I am stuck with the RHEL installation. I have got files that was dumped from a RHEL DVD on our corporate ftp site. After downloading i knew that if i directly burn it wont boot.

So i created a USB bootable pendrive and booted off with it and now the RHEL is not showing my external DVD ROM under the install source. I can see only Local cdrom, hard disk, nfs etc.

My DVD ROm is getting detected in BIOS.

So how do i install now.

I dont have currently any other linux system where i can create the bootable iso image (The procedure which i got from google)

please guide.

thanks

I'm guessing that your external DVD is USB attached, so there isn't an interface issue like with parallel port drives. If so, you should be able to go to one of the pseudo terminals by pressing Alt-Fx where x is 1 - 4. One of them is a command prompt and you should be able to manually mount the DVD drive. You might have to insmod the DVD kernel module.

However, Local cdrom is likely the DVD drive. Have you tried that?

Yes i have tried the Local CDrom option, it says it cannot find the Red Hat enterprise CD in that.

Yes the External DVD drive is USB attached and is recognized by the system BIOS but not recognized by RHEL install.

How & where do i load the drivers for it so that RHEL can recognize it and show me an option or read the DVD from it and start the install.

OK, one option is to boot the system with a LiveCD like KNOPPIX, create a file system and write the installation files to that hard disk partition. It may be the simplest and most straight forward option.

If you really want to use the CD/DVD, then you will need to press Ctrl-Alt-F2 to get to ptty/2 where the shell console is located. From there you should be able to insmod the "cdrom" kernel driver if it isn't already installed. You may also need to insmod "sr_mod" to get the DVD working. You may want to lsmod to see what is already installed before trying to insmod.

The redhat link is for the pseudo ttys (they call them virtual terminals).

You would press Ctrl-Alt-F7 to get back to the X Windows installation windows.

The redhat link is for the pseudo ttys (they call them virtual terminals).

Virtual terminal is the correct name for them. Pseudo terminals are what you get when you SSH or telnet into the system, i.e. /dev/pts/N.

TTYs (i.e. non-pseudo) are what you used to have when each tty number was dedicated to a physical, e.g. serial, line to a specific physical terminal.

Just being pedantic.
