Another Update! "old post 2: I will try a manually install to external usb disk and see if it still breaks the mbr of the internal disk... keep ya updated!"
I did it and just finished 2 test installs on a external memory-stick. One affected the "mbr" on my internal "/dev/sda" the other install did nothing to the "mbr" on "/dev/sda". I found out why! swap partition: My internal first harddisk /dev/sda also contains a swap partition, during install of ubuntu to external memory stick /dev/sdf, it "also" selects the "swap partition" on my "internal harddisk" for swap. As this is "automatically" done during the "manual" partitioning of the installation, I consider this as another serious BUG! because I never asked for it! When I manually deselect the swap volume on /dev/sda and continue installation and manually select the mbr/grub install for /dev/sdf everything works. Booting from internal hd still works and booting from external memory stick after deselecting the swap on /dev/sda! last and I will try one install with automatic partitioning just to the external memory stick for the last test, If that one also screws the mbr on my internal disc than there is a serious bug somewhere.... -- told ubiquity to install grub to sda6, but it breaks grub on mbr https://bugs.launchpad.net/bugs/409575 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
