Hi, I just downloaded the 2 iso

[Guest_imported]

Hi,

I just downloaded the 2 iso files for Red Hat 7.2 and burnt them onto CD. I am sure that my PC can boot from the CD drive as I install Win2000 on it that way, but I can not use my newly created Red Installation CDs.

Any ideas why? Do I need to do something with the ISO files before burning them on the CDs?

Thanks a lot for the help.

Hi,

If you just burnt those CDs asis then I would expect them to be bootable. You could check your PC's bios to see in what order the drives are booted from - obviously you need to have the cdrom first, i.e. before the hard-drive(s).

If the bios is correctly configured (you do F2 / F1 / esc or suchlike right at the very start of the PC boot to enter bios setup - exact key to hit varies by bios make) then maybe you have to create a boot floppy. You need to download the boot.img file (

http://www.mirror.ac.uk/sites/ftp.redhat.com/pub/redhat/redhat-7.2-en/os/i386/images/boot.img)

and create the floppy, then boot from the floppy to start the install. See -->

http://www.redhat.com/docs/manuals/...-steps-install-cdrom.html#S2-STEPS-MAKE-DISKS

.

For general info on bootable CDs see -->

The boot sequence is correct. I'll try with a boot floppy.

Thanks for the help.

What is an ISO file? Is it supposed to be 'decompressed' before use?

I could boot from the boot floppy but when it came to precise on which media was the Red Hat installation package, it could not find it on my CD...

Hi,

An ISO file is a ISO9660 filesystem contained in a single 'image' file. I guess you could compare it to a big zip file with lots of files and directories inside. You can mount an iso image like this :

losetup /dev/loop0 whatever.iso
mount -t iso9660 /dev/loop0 /mnt/iso

(where /mnt/iso is an existing mount point of your choice)

Then do 'ls -l /mnt/iso' and you should see whats inside (all the files and directories).

('losetup -d /dev/loop0' deletes loop association)

The mistake sometimes made when burning iso images is that people just do it as a file copy so all thats on the CD is the same iso file. You need to select the options in Gcombust or whatever to burn an existing iso image - then it will work.

Hope this helps
