View Full Version : [ubuntu] can't install because can't umount /cdrom

Hello, 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
/dev/sda2 21G 250M 20G 2% /media/Documents
/dev/sda5 47G 180M 45G 1% /media/Ubuntu

I'm not putting error messages because they're in french. it just says: can't continue because can't unmount /cdrom.
