Hi,Did you verify your DVD was made correctly? DVD's are harder to get right,
I've a problem mounting a DVD.
Basically I'm upgrading from RedHat 7.2 to Fedora Core 5 and I've burned the FC5 install DVD. I swapped the CD drive in my Linux PC for a DVD drive (Pioneer 109) booted and typed 'mount /dev/hdc /mnt/dvd' no problems, it worked fine and the files were all accessible in '/mnt/dvd'. So I tried booting from the DVD... can't boot from DVD's with the system BIOS. Oops. So then I tried booting from a Linux boot floppy disk - the kind to allow you to use 'parted', 'mount', and not much more. This allowed me to mount the DVD drive from /dev/hdc but then told me 'no medium is present' in the drive --when the same DVD was in the drive. So I rebooted into RH 7.2 on my hard disk, and now when I try to mount the drive using the same command as before it now tells me again that 'no medium is present' in the drive, when before it worked fine. Several DVDs (that I've verified work on another PC) all get the 'no medium is present' message from 'mount'.
Please advise what the problem may be and how to resolve it.
and some writers are better than others. From what I have heard, the
Pioneer drive should be very good. I also thought that Plextor would be
very good, but it produces expensive coasters, in general. Memorex,
LiteOne work fine though, IME.
It's been a while since I was using RH7.2. I am not sure it would handle
the extensions to iso9660 which allow optical to go beyond 650M. Your
DVD disc could be fine, but it if the OS lacks the UDF extensions to
iso9660, then it could report "no media found," as a general error
message. If you could actually boot from the DVD, those messages might
disappear inside the setup platform, and within your new install.
Yesterday, I discovered an interesting utility which makes it possible to
boot cds/dvds when BIOS support is lacking. I read about the method here:
I was able to make a boot floppy image which encapsulates the method. Let
me know if you'd like me to post that image.
Many thanks Douglas. Yes, I verified the DVD burned correctly and I even mounted it and accessed some files using RH 7.2 before things went wrong after trying to boot from it, etc.
I would very much like you to give me a copy of the floppy image please. If possible could you upload it to easy-sharing which is a file sharing web site, and much less hassle (for both of us) than dealing with files posted to newsgroups, and you can post the web link it gives you in a reply in this thread.
Many, many, thanks and regards,
