Hi Scar, The "problem"/feature made it into the release installer, but it has been noted in the release notes. Consider yourself lucky to be able to change it to IDE mode and clean the partitions. To confirm this is the problem you have described, try installing Ubuntu from a preseed file containing the following option: d-i partman/alignment select cylinder
This should cause the setup to align partitions to the cylinder instead of the optimal behaviour. If everything works then you have encountered this particular bug. -- BIOS hang - Unable to boot after installation https://bugs.launchpad.net/bugs/551965 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
