I don't have a formal specification for the MBR partition table, but http://en.wikipedia.org/wiki/Master_boot_record includes phrases like:
"scans the list of partitions in the MBR's embedded partition table to find the only one that is marked with the active flag" "As there can be only one active partition within the partition table, the MBR code can simply assume that the active partition on the current drive is bootable." I am extremely nervous about changing partman to permit multiple bootable partitions. I think it would be very risky given the variety of BIOS implementations out there; there is a long history of slight variations from common practice causing boot failures. Can we not get Truecrypt to support some other mechanism? After all, it is free software. ** Changed in: debian-installer (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/849760 Title: alternate installer does not allow multiple partitions to have bootable flag "on" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/849760/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
