General :: Cannot Mount CDROM When Booting From Live CD HP DV6?
Dec 3, 2010
I'm trying to get back into Linux after a few years off.
I have tried booting from a Live CD using Flash Linux and Damn Small Linux.
Flash Linux reports unable to mount CDROM and then provides a command line - I assume I have the kernel, a shell and little else at this point? Can I mount the CD and continue?
DSL seems to do something similar but freezes with a blank screen. I have the option of entering parameters prior to booting with DSL (but not with Flash) I have tried the parameter which copies the CD to RAM and then boots without success.
I plan on installing Debian to my HD in the near future but felt like playing around with Live CDs prior to this in order to get reacquainted.
I have googled this issue and it seems there are other noobs out there with the same model of PC (HP DV6) who are having similar problems but I could not find a solution.
As an aside - this is the kind of issue that IMO, still prevents Linux from becoming a mainstream OS.

I tried to mount my CD Rom drive and got this response: "mount: can't find cdrom in /etc/fstab or /etc/mtab"
I did see the CD Rom drive briefly after I upgraded from 10.04 to 10.10 but I couldn't access the drive and when I logged back in.

I'm trying to install Lucid on a computer with windows already present. When I ran trough the install procedure no drives show up at the partitioning stage. So I check some things out and it turns out that /dev/sda1 is mounted to /cdrom and I can't umount it because it says the disk is in use. I'm booting with the live-cd downloaded from ubuntu. Why is this happening? Previously with older live-cd's I always have to mount the HD manually if I wanted to access it for any reason?

I'm using the Ultimate Boot CD, and I've added a bunch of customized .iso's to it. I can boot into those .iso files fine, but most of them are mini-versions of Linux that are designed to run off of a CD. When they try to boot, they try to run off the CD (which obviously isn't there since they're on a USB drive) and then either freeze, or don't work in some other way.
Is there any way to edit the .iso files to tell them they're booting off of a USB drive? I'm assuming there'd be something somewhere in the boot configuration files to do this. Where would that be? I would think it'd be different for different ones, but are there some places that are standard for live CDs? What would I have to change? EDIT: Just to make exactly what I'm asking clear...I know there's stuff all over the place on how to boot a .iso from USB. That's not the problem, I can already do that. What I'm wondering is how to make the OS stored in the .iso realize that it's booting from USB and not CD?

When I start my system on the Ubuntu 10.10 CDROM I get a tiny icon at the bottom, then the screen shuts off due to no signal. So I cannot run the Live CDROM. Relevant here is that Debian CDROM runs just fine. (Lenny installs and runs good, but squeeze does not) Linux Mint (based on Ubuntu) gets me a pretty graphical welcome screen, then the monitor shuts off just like Ubuntu and Kubuntu.WinXP installed and runs without a hitch.
My system: Gigabyte GA-P43-ES3G with 4Gb ram, 750 Gb SATA HDD, Nvidia Quadro video card.I have gone through the BIOS settings looking for clues:SATA AHCI mode is set to IDE (versus AHCI)SATA port 0-3 native mode set to enabled (versus disabled which would be legacy IDE mode)Azalia codec set to auto (verus disabled)

I can see, that openSUSE mounts cdroms (at /media) according to cd label (eg. /media/data_dvd_x). My problem is, that several applications (eg. a cd cataloguer) expecting to find the cd at /media/cdrom0, or something similar. Is it possible to fix it? (Tell openSUSE to mount cds at a single point)?

I am trying to add my natty Live Cd as a repository, by issuing apt-cdrom add, but even autodetecting the mount point fails.
Code:
apt-cdrom --auto-detect add
How do I determine the mount point for the cdrom in order to tell apt-cdrom where to look?
Output:
Code:
Using CD-ROM mount point /media/apt/
Identifying..
E: Unable to stat the mount point /media/Ubuntu-4011.04-40amd64/ - stat (2: No such file or directory)

I'm an experienced Linux developer who has run into a little problem. I'm using a National Instruments 8170 chassis, among the normal ports, it has a FDD and USB port but this model does not allow booting from a USB CDROM ( I tried a BIOS update, that didn't help either ). I made this cool customized 550MB FC8 LiveCD wtih X, GCC, various apps, etc. and a kernel 2.6.30 & 2.6.18 boot floppy disk with all the needed drivers. The floppy boots to a shell with all the busybox utils, etc. and detects the USB CDROM media and all its files.
My Question is: How do I get the kernel and initrd on the Live CD to start or boot after booting from the Floppy disk ?, I mean, I want to load linux again but this time from the CD after booting linux from floppy, if that makes sense. I'm just using the floppy to boot and recognize the USB CDROM. This can be done with MSDOS and loadlin but loadlin has an issue(it hangs) with the newer kernels (2.6.18 and greater). I searched for the loadlin source code to port it to linux but was unable to find it on the net.

I'm running Fedora x86_64. I need to setup a virtual machine to do some work on ARM platform. Thus, I've installed QEMU.
Code:
qemu --version
QEMU emulator version 0.13.0 (qemu-kvm-0.13.0), Copyright (c) 2003-2008 Fabrice Bellard
Then, I have dowloaded an ISO image of Debian 6.0 armel.Following instructions on official wiki, I have first created an empty disk image,
Code:
qemu-img create -f qcow debian-armel.img 650M
then I have attempted to boot from ISO image;
Code:
qemu -m 512 -hda debian-armel.img -cdrom debian-6.0.1a-armel-CD-1.iso -boot d
Boot process hangs with the message:
Code:
Booting from cdrom...
639 medium detected
Boot failed: Could not read from CDROM (code 0004)
No bootable device
link refers to Fedora 12, but it seems still unresolved...

I am running Karmic x64 on a HP laptop that has a cd/dvd burner. I have a r/w cd with files on it and I wish to add/remove files to it. After it mounts automatically on insertion, I unmount it and remount with:
sudo mount /dev/sr0 -t iso9660 -w /media/cdrom
(I tried assorted other hare-brained things also) but it always says that the filesystem is read only. Do I need to use a different device than sr0? Is it even possible under Ubuntu?

My cdrom was sort of working, but the tray was physically damaged. The usb was working without a problem.
After replacing the the cdrom drive with a similar model known to work well I could not get it to mount. I then tried to move important files to usb to try a fresh install. The usb stick flickered when I put it in, but it didn't mount. Same behaviour as the cdrom, the light goes on when I turn on the computer, but once I'm logged in I can't access the cdrom.
I have tried multiple variations of playing with fstab and trying to mount things in terminal to no avail. I just can't get Ubuntu to recognize the usb or cdrom even though their lights go on when I first try to use them.

I have a problem to mount my cdrom as a regular user. After inserting a cd, I receive this error message:"Error mounting: mount exited with exit code 1: helper failed with:mount: must be superuser to use mount" After mounting the cdrom as superuser with "sudo mount /media/cdrom".I can access the cd also as regular user. This behavior is inconvenient and I would like to be able to mount the cdrom as user.Honestly, I do not have the experience to tell if this should be fine or not. Do you have any advice for me to fix this problem? I am running Ubuntu 9.10 with a 2.6.32-02063209-generic kernel.

I have recently installed Xbuntu on my old laptop (An IBM iSeries 2621) - yes its an old piece of kit with a USB 1.0 port, a cd-drive and an internal floppy.My problem is that even though removable media are set to auto-mount in the settings; when I put a floppy disk in, or a CD-ROM, they do not auto-mount so I cant access the disks (the laptop does not have wireless (or even an rj45 port!! - it only has an internal 56k modem) - hence why I REALLY need to get the CD-ROM working and recognised by Xbuntu as I have burned some packages that id like to install to CD-ROM. (a working floppy would definately be a bonus as id like to save my documents there)

I've been working on creating a Live CD with the tools I want, just for my use with system recovery and repair. For the most part, things have gone very well. The Live CD actually works fine, somewhat. I have run in to a problem where it doesn't actually boot on a lot of hardware.
What happens is during boot, while the modules are loading, the boot process hangs and the disc drive spins down. While I thought it might be a kernel problem, I'm using the .config from the latest gentoo Live CD, which boots fine on the same hardware.

When I boot from the CD, it starts to boot and then continously repeats:
Code
Initializing gfx code...
boot:
gfxboot:
It stops on boot for about 10 seconds each time then gfxboot for not even a second before the cycle continues. I have tried more than one CD, so I don't think that is the issue. It even did the exact same thing when I tried it on PCLOS 2010.10. Both versions I tried were KDE. trying to figure out how to get past this.
