The kernelparameter 'partman/alignment=cylinder' seems to fix this behaviour.
When you add the 'partman/alignment=cylinder' kernel-parameter before starting the Linux installation, the partitioner will not realign the extended partition to MB-boundaries and eCS LVM-info will be preserved. So, installing Ubuntu 10.10 will go like this: - Create the extended partition (and swap) with eCS MiniLVM - Boot from the Ubuntu live CD - Press a key to get the menu (this takes a second before being displayed) - Choose your language - Press F6 - Press ESC Now you see the line with the kernel-parameters that looks something like this: ..... quiet splash -- Insert the partman-parameter, so the line reads like: ..... quiet splash partman/alignment=cylinder -- Double-check you spelled the parameter correctly. Now proceed with the Linux installation. Note: I have not tested this on non-Debian derived distro's. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/669459 Title: Ubuntu installation writes into foreign partitions and MBR without permission, damaging other operating systems on the disk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/669459/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
