I really appreciate your help. I should add that I am using an older version of BIBM - 1.14.
The Windows 7 and Windows 10 partitions are labeled bootable, while the other partitions are not. However, in all cases the bootable setting is greyed out (and labeled obsolete).
But I think there is something wrong with my partition table. For starters, there is no free space listed, but I know there is free space on the drive (at least at the end). But worse, when I look at the Properties of the Data partition (which is the last partition) a message comes up saying "Invalid Head and SPT values exist in the BPB. Fix it?" I said No. Should I say Yes?
I tried removing the Data partition from the Windows 7 Boot Edit configuration, but Windows 7 still would not boot.
