Still an issue in Oneiric. I also followed teagu-wisc, but I copied the content to a USB stick and mounted that one. Just in case you don't fit inti the memory.

[Bug 313452] Re: Jaunty, Karmic: when booting from one partition and installing to another, installer fails to unmount '/cdrom' this halts installation.
Still an issue in Natty. Worse, actually, because the installer starts trying to copy files from /cdrom right after it finishes partitioning, and you don't have time to re-mount it. A workaround (for systems with enough RAM) is to copy the files in /cdrom to the running ramdisk. Ie, after booting the LiveCD but before starting the installer, open a terminal and do: - sudo cp -r /cdrom /cdrom2 - sudo umount -l -r -f /cdrom - sudo rmdir /cdrom - sudo mv /cdrom2 /cdrom Then install - it completed for me without any problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/313452 Title: Jaunty, Karmic: when booting from one partition and installing to another, installer fails to unmount '/cdrom' this halts installation.

The issue seems to be that you only ever need to write to the partition table if it is changed.

[Bug 313452] Re: Jaunty, Karmic: when booting from one partition and installing to another, installer fails to unmount '/cdrom' this halts installation.
Same in Lucid release. I created a bootable live-USB of Ubuntu 10.4 netbook on partitioned USB stick /dev/sdb2. I tried installing to empty partition /dev/sdb3. The installer stops with message reported above Failed to unmount partition The installer needs to commit changes to partition tables but cannot do so because partitions on the following mount points cound not be unmounted: /cdrom /cdrom has /dev/sdb2 mounted on it. As all partitions have been pre-created, there is no need for ubiquity to make changes to the partition tables. I repeated testing, getting the same error message, whether: a) formatting the new partition /dev/sdb3, boot installed to /dev/sdb b) not formatting the new partition /dev/sdb3, boot installed to /dev/sdb3 c) not formatting the new partition /dev/sdb3, no boot loader installed. -- Jaunty, Karmic: when booting from one partition and installing to another, installer fails to unmount '/cdrom' this halts installation. https://bugs.launchpad.net/bugs/313452 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 313452] Re: Jaunty, Karmic: when booting from one partition and installing to another, installer fails to unmount '/cdrom' this halts installation.
Hello everyone, I have been experienceing the exact same problem as described in this bug, so I have some feedback too. My configuration is the same as described by Xnyper in comment #10, 3 partitions, and I also get the error message with /cdrom. I have been happy to find the above workaround, typing sudo umount -l -r -f /cdrom just after the who are you panel and before confirming the install summary. _But_ this was not going to be so easy for me... The installation goes well until the end, and proposes to reboot. But when the computer starts up, after having displayed Grub loading, it automatically launches the memtest86 program, and does not give any alternative... Still I do not understand how the installer can copy files from partition 1 (/cdrom, if I got it good) to partition 2, while /cdrom is unmounted... I am currently testing with other versions of the distribution.

Found a workaround thanks to this guy: http://jaredforsyth.com/content/unetbootin-failed-unmount-cdrom I just opened up a terminal window and ran: sudo umount -l -r -f /cdrom I did this right after the Who are you window, before the Installing System window. -- Jaunty, Karmic: when booting from one partition and installing to another, installer fails to unmount '/cdrom' this halts installation. https://bugs.launchpad.net/bugs/313452 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
