No, it is not wrong. I am coming from a totally different direction, place, where I don't think you have ever been. I have experienced what I am talking about for twenty years or so. It goes against Bill Gates wishes for control. "Assigning drive letter C:" is more than just setting a partition active. In the current setup I have the following 4 "primary type" partitions First Primary - Drive C: Second Primary - Drive C: Third Primary - Drive C: Extended Partition Now, the above is a slight overstatement ( for getting attention purposes ) because of course there can not be three Drive C: partitions. I used OS/2's Fdisk to create these partitions. It has a function called "Assign Drive C:." So one of the three partitions will have the drive letter C: assigned to it and the other two will not have ANY drive letter assigned to them. The Drive C: partition will be the active partition. Now, I have experimented and used a DOS Fdisk, and it will move the "Active" assignment from one partition to another. However, it will not move the Drive C: assignment. So, a DOS Fdisk can not be used to change which of the three partitions will be bootable. OS/2's Fdisk can and some of the Boot Managers can. GAG is the only boot manager other than OS/2's that I have any experience with. The going back twenty years bit is with Zenith's improved versions of MS DOS. Zenith would replace Microsoft's Fdisk with a program they called "Part.exe." It behaved the way OS/2's Fdisk behaves. With part, one could create up to 4 primary partitions on a hard drive. Each and everyone would be drive C:. Using "Part", the user would decide which one to boot from. Mr Gates didn't like that and did his best to wipe that flexibility out. > it just looks so to the >user, because if the active partition is a valid DOS FAT >partition, you will boot the OS that is loaded from the >bootsector in that partition - and this DOS will assign >drive letter C: to its boot partition.)

OK, that helps explain what I am seeing in the GAG Boot Manager setup. >Hope it helps, Yes. > Matthias Thank you sir. I am trying to end this thread.
