http://linuxexchange.org/questions/877/ubuntu-install-from-hard-drive-alternate-iso-1004-couldnt-mount-cd-rom<p>Trying to install Ubuntu Studio 10.04 from the Alternate installation ISO image copied to Hard drive. Installation begins. After detecting Keyboard etc, I get this message</p> <hr> <p><strong>Detect and Mount CD-ROM</strong><br> <em>Your Installation CD-ROM couldn't be mounted. ... Try again to mount the CD-ROM?</em></p> <hr> <p>I'm following this guide: <a href="https://help.ubuntu.com/community/Installation/FromLinux#Procedure%201" rel="nofollow">https://help.ubuntu.com/community/Installation/FromLinux#Procedure%201</a></p> <p>Running an existing Ubuntu 10.04. Copied these files to the present ext4 partition.</p> <ul> <li>Alternate ISO image (to /)</li> <li>vmlinuz, initrd.gz (from the ISO image to /studio/)</li> </ul> <p>Edited Grub - </p> <pre><code> menuentry "INSTALL ubuntu studio(iso on /dev/sda4)" { insmod ext2 set root='(hd0,4)' linux /studio/vmlinuz root=/dev/ram ramdisk_size=1048576 rw initrd /studio/initrd.gz } </code></pre> <p>Basically copy-pasted grub entry for the existing installation and modified. ISO etc for new install is on the same drive, so I hope the hd0,4 numbers are correct. (besides, installation does begin.)</p> <p>Tried with/without "root=/dev/ram ramdisk_size=1048576 rw" in 'linux /stu...' line. Still, "Your Installation CD-ROM couldn't be mounted". Any help is greatly appreciated.</p> <p><em>I have 2 ubuntu installs: 9.10, 10.04. LVM and Non-lvm partitions. Couldn't burn a DVD or create usb startup disk.</em></p> <p>Ananth</p>enMon, 21 Jun 2010 14:26:01 -0400http://linuxexchange.org/questions/877/ubuntu-install-from-hard-drive-alternate-iso-1004-couldnt-mount-cd-rom/893<p>You said you copied </p> <blockquote> <ul> <li>vmlinuz, initrd.gz (<strong>from the ISO image</strong> to /studio/)</li> </ul> </blockquote> <p>but the instructions you referenced say</p> <blockquote> <p>Step 3.
