Here's the notes I have from installing 10.04 on top of an existing encrypted disk. I think it might be a little easier than using the terminal, but maybe not.
* Backup /etc/crypttab * Boot new CD, choose rescue * Enter passphrase for encrypted disk * At choose root partition, Back, to menu * Go to partition disks * Select partitions, remember /boot * Format root partition and /boot, leave others * Continue with installation * Restore /etc/crypttab As per http://ubuntuforums.org/showthread.php?t=1205372 I agree, I think this (or #420080) is release critical. Wiping encrypted data without warning is totally uncool! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/285890 Title: Does not show encrypted partition -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
