Description of problem:
I have downloaded the RH Lin. 7.1 ISOs from the site, extracted them and
burned to CD (stupid Nero Burning tool), but when the installation tool
boots (and it can boot from the CD) it enters the text mode and stops with
"I could not find a Red Hat Linux CDROM in any of your CDROM drives.
Please insert the Red Hat CD and press "OK" to retry"
If I press OK, the same message reapears. In the console found at Alt-F3
message "* trying to mount device hdc" is displayed.
What is even more curious is that if I make the ISOs back from the disks
and put them on the HD, the installer doesn't complain. Because I have to
do another installation it would be impossible to use this method again.
I have already ordered te official Red Hat package, but because of the
time frame I am in, I need this ASAP
Steps to Reproduce:
1.Insert CD and boot
2.Choose the language and keyboard
3.Choose to install from CDROM
4. System hangs
Actual Results: I could not find a Red Hat Linux CDROM in any of your
CDROM drives. Please insert the Red Hat CD and press "OK" to retry
Expected Results: Continuation of installation
I was quite able to install Red Hat Linux 7.0 using the same procedure
that I have described.
You need to make a boot disk with the boot.img file in the /images directory of
the cdrom. Boot off that floppy and then select CDROM as the installation
media. Please reopen this bug if this doesn't fix the problem.
No, the problem is not in the booting image as the system boots correctly, but
in the access to the CDROM. I have tried both ways - booting from diskette, and
booting from CDROM - it boots, but doesn't load from CDROM.
Are you sure that there's nothing wrong with the cd? 7.1 used a 2.88MB boot
image, and some motherboards were not able to see the second stage installer on
the cd if you booted off the cd. Booting with a floppy avoids this problem, but
if you still can't see the cdrom, I don't know what the problem is.
Well, I think that everything is OK with the CD.. You can read from it in 7.0,
you can read from it in 7.1 once installed, you can create ISO from it... One
idea: is there some kind of FS support for ISO (like Joliet extension, or
something like that) that is not built into the kernel on the diskette image,
but is built into the standard kernel? I am asking this because I wasn't able
to burn the CD straight from the ISO (Nero Burner doesn't have this option),
but had to extract the ISOs, and then burn them as files on the CDROM. I have
enabled Joliet extension to allow for long filenames.
Apart from this, I have no other idea... Perhaps some sort of copyright
protection you have built into CD ISO image?
No no no, there is no copyright protection built in to the ISO images. The cd's
are not going to work if you extract the files and simply burn them to the cd.
I am surprised that the cd even boots at all. You need to find a different cd
burning application that will let you burn an iso to the cdrom, and then things
This is not an installer bug...the cd's were burned incorrectly.
