[gPXE] Why disk not appear in the disk management tool?

[Miller, Shao]

Good day Alrich,

I repeatedly asked which guide you were following because without a
guide, you might not be aware that you should not have the original
source for the SAN image (a local HDD) attached to the same computer.
Windows cares about a disk signature in the MBR.  If two disks are
attached with the same disk signature in the MBR, this can certainly
complicate matters.  Same thing with your two-SAN connection...  Are
they the same image with the same MBR?  Each disk you are using should
have a different MBR signature.
