I have noticed that the Converter doesn't order the drives correctly all the time on dynamic disks. Thus a one physical drive/one logical drive box converts fine for me... but a multiple drive box doesn't.
What I have done to make this work is:
1) Break the mirror
2) Isolate the C (system) partition to it's own drive This can be done by creating mirrors of the other partitions then breaking the mirror on the system disk side.
3) Convert the Physical box and use an odd amount of space for the system partition.
4) Mount on the VMWare server and edit:
a) Remove all the Hard Disks
b) Add the first Hard Disk and make sure you select the system partition.. you can ID it by the odd size you made it.
c) Add the other hard drives in.
5) Start the Guest OS
Now you shouldn't get the error:
No bootable CD, floppy or hard disk was detected.
Hope this helps!!
