Ubuntu Installation :: Can't Install Because Can't Umount /cdrom?

Jul 30, 2010

I managed to boot from hard disk, everything works ok. But Gparted has a bug, it works in Live Hard Disk, but not when I click the install icon because it can't umount /cdrom. But I solved that by formatting ext4 and swap area from gnome-panel Live Hard Disk and only put mount point / after click on install.But problem stroked back: install is not possible because it wants to umount itself before installing, wich cannot be possible. I'm installing it in a new place /dev/sda5. Live Hard Disk is booting from /dev/sda3.

ubuntu@ubuntu:~$ df -h | grep sda
/dev/sda3 2.0G 726M 1.3G 36% /cdrom
/dev/sda1 43G 17G 26G 41% /media/Windows

Ubuntu Installation :: Cannot Read From CDROM Error During USB Install

Jun 6, 2010

I downloaded the Ubuntu Server 10.04 64bit ISO and the universal USB installer, created a USB install disk and booted from it. I started the installation and right after keyboard setup I got an error saying Unable to read from CD-ROM, retry/abort. Looking at the alt-f4 log it was unable to find a file, fs-secondary.udeb I hit alt-f2 and cd'd to /cdrom/pool/main/l/linux (I think, this is all from memory) and found that file, almost. The file there was fs-secondaryblahblahblah.ude, no b on the end. I tried renaming it but the filesystem was mounted read-only.

So, cd back to /
Type mount and hit enter.
Take note of the cdrom entry, at the beginning of that line it will say /dev/? Mine was like /dev/svd0 or something like that. Remember whatever that is.
Then type umount /cdrom
Then type mount -t vfat /dev/????? (whatever your device was from earlier) /cdrom
That will mount the cdrom rw so you can rename the file to .udeb
Then press alt-F1 and press enter to retry and the installation will continue like normal.

Fedora Installation :: CDROM Drive Not Found For Install?

Jul 11, 2010

I downloaded and burned the Fedora-13-x86_64-dvd iso to install on my shiny new box (MSI NF980-G65 MB, AMD Phenom II x4 945 CPU, 8GB Corsair DDR3 memory, generic ATAPI DVD drive, 2 500GB SATA drives, 2 1.5TB SATA drives). I boot from the DVD and and take the default install/upgrade option on the menu. I've tried with the default boot options and with about a dozen different options, all give the the same thing.

Looking console 3, shows the following:

ERROR loader: removing ddmode.conf failed
ERROR loader: got to setupCdrom without a CD device

It can't find the CD/DVD drive that it booted from. The install on console 1 is prompting for a driver to load. Do I need to download a driver for a generic ATAPI/IDE CD/DVD drive?

Debian Installation :: Attempt To Install From USB Fails To Detect Cdrom

Jan 31, 2016

I am attempting to install debian for the first time on my pc that has no cdrom drive. I downloaded the Jessie CD image and wrote it to a 4GB stick, it didnt work. Then tried the netinstall image but face the same issue.

To write the usb stick I used unetbooting first, then tried win32diskimager and finally tried DD while stick was not mounted

Code: Select alldd if=debian.iso of=/dev/sdb BS=4MB; sync

Issue is still the same: I boot from the usb and after selecting language and keyboard it fails to detect cdrom drive (no drive at all in my pc). Same behavior using normal or expert mode.

Im also unable to manually specify the drive (it looks at /cdrom and I wanted to change it to the usb stick itself or mount usb to /cdrom but I cant find my stick in /dev)

Ubuntu Installation :: Cannot Install 11.04 ErrorCan Not Mount /dev/loop0 (/cdrom/casper/filesystem.squashfs?

May 7, 2011

I have had a dual boot on my system since first trying Ubuntu a few months ago.I had a few problems when i upgraded to 11.04 (mainly due to the new desktop Unity), but after some great help here, we had the old desktop running again.I have Windows running on my spare Computer in case i should need it for any reason, though can not think of one lol Now i am used to Ubuntu (from the using side, get lost in terminal etc so here i come if i need help) i decided i would totally commit my main computer to Ubuntu.I downloaded the latest iso from the Ubuntu site, and burnt it to CD, inserted in my main computer & rebooted. It goes past the first purple ubuntu page (hit a key to choose language & also get a selection Menu) then goes to black screen and i get:

BusyBox v1.17.1 (ubuntu 1:1.17.1-10ubuntu1) built-in shell (ash)Enter 'help' for a list of built-in commands.(initramfs) mount: mounting /dev/loop0 on //silesystem.squashfs failed: Input/output errorCan not mount /dev/loop0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs(hope i typed that i correctly)I have burnt the iso image numerous times, using different disks, speed (from x4 - x52) and burning programs

Ubuntu Installation :: Synaptic Can't Fetch Cdrom?

Jul 21, 2010

I'm attempting to install Lucid on a new Acer Timeline X 5820T and having a tons of problems.

First of, I've got no internet connection either wired or wirelessly.

I've found several posts claiming that the ethernet card just needs a driver installed to work correctly.

However, to make the driver I need build essential installed, but no problem, I've got my CD, I'll just install them from the CD.

However, when I attempt to install them through synanptic it tells me that it:

Failed to fetch cdrom:[Ubuntu 10.04 LTS_Lucid_Lynx_ - Release i386 (20100429)]/pool/main/p/patch_2.6-2ubuntu1_i386.deb

File not found why it can't fetch the cdrom? Ubuntu recognizes it and I can browse it just fine.

Ubuntu Installation :: Does Not Detect The Presence Of CdROM

Jun 8, 2011

I have just had my Ubuntu 10.04.2 Luci installed under my Windows OS. Things seem to be fine until I find out next that my copy of Ubuntu does not detect the presence of the cdROM which installed the software itself on my desktop machine.

I have tried searching high and low for clue in this forum, tried all the recommended tricks to find out at last that there is no cdROM listed under my DISK UTILITY and when I input the following comman,

sudo lshw -class disk -class storage I only happened to see my hard drive and some USD drives being listed.

Also, Brasero Disc Burner does not detect the presence of a cd/ DVD rom devices.

Ubuntu Installation :: SDA1 Mounted On /CDROM While Booting From CD

May 5, 2010

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?

OpenSUSE Install :: Force 80 Pin Cable Detect On Cdrom?

Oct 16, 2010

I need to force 80 pin cable detect on my cdrom. According to the kernel-parameters.txt file you can do this by using libata.force=(port).(device) 80c Here is the actual explanation from the kernel file: libata.force=[LIBATA] Force configurations. The format is comma separated list of "[ID:]VAL" where ID is PORT[.DEVICE]. PORT and DEVICE are decimal numbers matching port, link or device. Basically, it matches the ATA ID string printed on console by libata. If the whole ID part is omitted, the last PORT and DEVICE values are used. If ID hasn't been specified yet, the configuration applies to all ports, links and devices.

My question is where do you find the proper port.device numbers? I'm guessing it's lspci but I'd rather be sure before I do something silly.. An actual working line for a cdrw as master on the first ide channel would be excellent. BTW my cdrw is detected as sr0 so the normal "ide" boot params won't work....

General :: Looking To Install System From CDROM While Other Distro Running?

Mar 19, 2010

Laptop has broken internal CDROM. I booted with floppy to get Puppy 431 installed from USB stick. Now I have USB CDROM access thru Puppy. I can mount and see the CD fine.

Is it possible to boot or install from a currently installed linux distro (Puppy)?

I have a second free partition ext2 available, sda2, and GRUB is working fine for me on boot.

(machine also doesn't have boot from USB option, yes, it's old, a project I am working on, I have Nimblex in CD now, I think it's a live cd, I would like to try a few different ones by installing to sda2 and wiping if ng.)

Ubuntu Installation :: Installing To A Laptop Without Cdrom / Usb Boot Options.

Jan 23, 2010

So, I have an old laptop that used to have windows/ubuntu until the drive got fubarred (no physical damage). I shoved the laptop as side as I didn't use it much anymore (it's an old, loud 2.4GHz desktop p4 in a dell--mostly toshiba--laptop. pcmcia atheros based wifi card and an ATI m6 graphics card. Laptop was new back in 2002-03 maybe).The Cdrom drive had died a while back, and it's not worth buying a replacement. The bios doesn't support boot to USB. What are my options for getting Ubuntu on there (9.10 preferably)? The drive has been formatted already, so there is nothing to boot into right now.

I can pull the drive and hook it up to my desktop (windows 7 machine only right now) via USB, and partition it from there, but I'm not sure how to get the installer on there. The MBR of the laptop drive will also have to be rewritten. Is there a way I can create a dos partition, load it with files, and start a linux install that way (maybe with grub4dos or something)?Or can I somehow boot into an ISO image on a partition?The only other thought I have is creating a floppy disk that will allow a network boot, but I haven't looked into that. I basically just want something to bring with on vacation that I can get online with. Browsing from the phone leaves a little bit to be desired.

Ubuntu Installation :: Installing Build-Essential With No Connection / CDROM

I'm having headaches about not being able to install build-essential on my 9.10. I don't have an internet connection and no CDrom. [URL]. So that solves it if you have a CD drive... What to do if a poor fella (like me) was to have a system with no CD drive? I installed from USB PENDRIVE and I suppose there have to be some command corresponding to apt-cdrom but for the USB drive but I can't find one.

Ubuntu Installation :: Booting To CDROM Makes Blank Screen?

Jan 19, 2011

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)

Fedora :: Permission Denied - Cannot Run Install Script From Automounted CDROM?

Nov 10, 2010

I'm running Fedora 14, with a SATA interface CD/DVD drive and I'm attempting to run an installation script on a CD for an embedded Linux learning kit.Logged in as root (su), I receive:bash : /media/EmbeddedLinux/install_tools Permission DeniedI have searched and see similar situations on the web, but not exactly the same.I cannot resolve this issue using chmod, and find no relevant exec rights set in /etc/fstab.Using mount I find the (automounted) CD drive on /dev/sr0.I've searched quite a bit but never could find the thread that was supposedly listed in this forum.I understand that I should be able to copy the contents of the folder to my machine, then execute, but if possible I would prefer to address the real cause, not go around it.Also, where on earth will I find the location of whatever is affecting the ability to execute from an automounted media?

Software :: OS Install Via Pxe - No USB Boot Option And A Broken Scsi Cdrom Drive

Aug 12, 2010

I have successfully setup a FOG server to image my Windows clients, so I have tftp, pxe and anything else related to booting to a pxe server setup and rocking. What I'm trying to do now, is use the CentOS net install files to setup CentOS on an old server with no USB boot option, and a broken scsi cdrom drive (it's a Dell PowerEdge 2400, with a single PIII 733 and 1.25GB ram).

Using the FOG Projects gparted wiki entry (adding gparted to the pxe boot menu) I was actually successfully able to pull the net install files over to the PE, and install CentOS 5.5 via local ftp server. At first it kept erroring out (I kept picking and choosing individual packages from the package groups), so I thought it may be an issue with the GUI install (the python script kept spitting back errors forcing a reboot). In any case, I finally got through the GUI install, but now I need / want to know how to force a text mode install.


the bolded "append" line is where I thought I could force the text mode install script, but that didn't work. The vmlinuz and initrd.img files were both pulled form the net install iso, NOT the livecd. Would that have made a difference? If not, what / where / how should I force the text mode install script?
