  1. Having issues installing Ubuntu. Keep getting errors!

    I have 2 live CDs of Ubuntu 7.04 and 6.06 LTS

    6.06 gave me this error and wouldnt install no matter what I did

    Uncompressing Linux... ok, booting the kernel.
    [17179589.684000] .. MP-BIOS 8254 timer not connected to IO-APIC
    [17179589.684000] kernal panic - no syncing : IO-APIC + timer doesn't work!
    Boot with apc=debug and send a report then try booting with the 'nopic' option [17179589.684000]

    7.04 got a tad farther it gave me however

    [bunch of random numbers] something about an I/O Error something else

    cant remember what it said and those errors filled up my screen and eventually the screen just went black and nothing happened for several minutes and It just stopped.

    whats going on, Why cant I install Ubuntu. Why does it keep getting rejected on my brand new computer?

    Please someone help me here. After all the trouble I went though getting Linux on this computer (just error after error until I reburned 7.04 live cd to a cd at 1x burn speed instead of max speed and it installed fine) It figures Id get a Problem when the OS is actually installed.... I swear If stuff like this keeps up Its gonna turn a Linux Newb into a linux hater, Its my first time using the OS and so far the Ubuntu Forums are proving to be slow and not giving me any fix suggestions.

    I have a Lite On CD burner/DVD burner Combo Drive, (SATA)

    Now once in linux I tried to back up some media files and stuff from a Burnt CD well I inserted the CD and nothing happened, so I manually searched for the CD Drive. Went to Places>Computer>CD-ROM1 Figured hey there it is, double clicked and got this.

    Unable to mount the selected volume
    mount: special device /dev/scd0 does not exist

    Yea so basically the CD Drive does not exist to Linux.

    Im stuck here, Im a newb to this OS and IM thinking "WTF How does it NOT recognize the existence of my CD Drive when crappy ol' windows xp (which Im keeping around for gaming) sees it just fine.

    At the suggestions of friends and the one person on the Linux boards whos waaaaay slow responding and making me impatient I have collected the following data and of course due to impatience of problem resolution Im posting here too hoping ONE of the two forums Im visiting will get me a quick fix before the days out Cause Beyond this issue I LIKE ubuntu, I just will not KEEP Ubuntu on this system If I cant effin use my Combo Drive cause Why Should I keep an OS I cant use my hardware with?

    Someone told me to do this... no work

    mike@Azerial:~$ sudo mount /media/cdrom
    Password:
    mount: special device /dev/scd0 does not exist
    mike@Azerial:~$

    so heres my /etc/fstab file
    # /etc/fstab: static file system information.
    #
    # <file system> <mount point> <type> <options> <dump> <pass>
    proc /proc proc defaults 0 0

    Someone on Ubuntu Forums then asked to show what I got when I typed lspci and lsmod into the command console heres what it showed back

    All that stuff is like trying to read japanese to me, I have no clue what ANY of it means. Maybe someone here could make use of what troubleshooting data they asked me to collect on linux boards and tell me how to fix it before I get annoyed with this and remove linux from this machine over this.

    Please try the follwing command and post the outpout:

    sudo mount /dev/hdc

    If that doesn't mount the drive, try this:

    sudo mount /media/cdrom

    Please post the output of the command(s).

    Regards :)

    I can never get Ubuntu to load either :(

    One time I think it worked but it had been streaming stuff like [17179654.492000] (or similar to it) up the screen for 4 hours before I unplugged it. The only reason I think it worked was because it didn't say error...

    Well My issue isnt that, Ubuntu works FINE for me, I just cant use my CD/DVD drive at all, and its the ONLY removable media drive I have on this computer!

    I tried that and heres what I got

    mike@Azerial:~$ sudo mount /dev/hdc
    Password:
    mount: can't find /dev/hdc in /etc/fstab or /etc/mtab
    mike@Azerial:~$ sudo mount /media/cdrom
    mount: special device /dev/scd0 does not exist
    mike@Azerial:~$

    About the only problems I've had with Ubuntu were with wireless networking, and some of that was because I had accidentally disabled the network card.

    It does sound as if your drive is, for some reason, not supported. Perhaps you'll have to wait until some of TechSpot's Linux gurus come around.

    Regards :)

    Or wait for v.7.10 to be released later this year in october

    Until then I need this problem fixed ASAP or I need to get another Distro of Linux to use until 7.10 is avalable

    VMWare Player and Ubuntu missing CD ROM

    I had installed Ubuntu as my primary operating system and my CD ROM worked fine as it did when I had XP as my previous OS.

    Now I have XP as the primary OS again and I have VMWare Player installed with Ubuntu. Windows still see my CD Rom but Ubuntu does not. When I try to read from it I get the following message: Drive "cdrom0" is not a CD-ROM device. Please correct your configutation. Failed to connect virtual device ide1:0.

    My ftab has the following:
    # /etc/fstab: static file system information.
    #
    # <file system> <mount point> <type> <options> <dump> <pass>
    proc /proc proc defaults 0 0
    # /dev/sda1
    UUID=f8c4e8ae-b3a0-43bc-9533-ed631e143db5 / ext3 defaults,errors=remount-ro 0 1
    # /dev/sda5
    UUID=21759d71-0c9f-49e7-93ff-830e236f2c44 none swap sw 0 0

    # Beginning of the block added by the VMware software
    .host:/ /mnt/hgfs vmhgfs defaults,ttl=5 0 0
    # End of the block added by the VMware software


    I also tried the commads earlier in the post and got the following:
    user@ubuntu704desktop:~$ sudo mount /dev/hdc
    mount: No medium found
    user@ubuntu704desktop:~$ sudo mount /media/cdrom
    mount: No medium found
    user@ubuntu704desktop:~$


    Any idea how to get it to work?

    Sir_Lancelot:
    When you used lsmod, it displays loaded modules. I did NOT see the cdrom module loaded. This is probably the reason your CDROM does not work. I'm not exactly sure what the solution would be though.

    spiderwayne:
    This might sound silly, but this message means that your CDROM seems to be working, but there is not a CD in the drive.
