Some more testing showed that it seems that the new alignment in parted of
partition start to multiples of 2048 sectors seems to either confuse grub or
the BIOS in a way that a considerable percentage of disk layouts that worked
fine
so far are not bootable.

Question is what to do now?

We use new alignment to be able to improve performance on disks with 4k sector
size and SSD. In addition the new alignment default is the same that Windows
Vista and Windows 7 use. So if the BIOS is guilty, this would imply that it
should also be impossible to install Windows Vista or Windows 7 on sich a
machine
if the windows partition does not start at the beginning of the disk.

Added parted maintainer to CC: maybe there the same problem was discussed also
on parted mailing list.
