fre,

That's interesting. Using BING manually to boot an OS by setting the MBR order and the active partition.

What I don't understand is why BING doesn't do this in your computer from the Boot Menu. If BING is installed you can do a sham boot by selecting an OS from the Boot Menu and holding down Shift while clicking Boot. The OS will not boot but the MBR is changed to reflect the MBR Details in Edit Menu Item. So the MBR you have been viewing in Partition Work should now show the Active OS in the first MBR slot. The same order as you have been creating manually.
