I have a question about Dell Optiplex 745, 755 and 760 computers. Can someone tell me what is the differences between the 3 models? Aside from the obvious. I have noticed if you take a drive that is configured for a 745 computer, you can't use that drive in a 755 or 760 computer. Why not?

I am talking about a standard WD 80gb SATA drive. Again, if you take this drive after it has been configured for a 745 desktop computer and insert it into a 760 computer, you will not get pass the Windows logo screen. The computer will automatically reboot itself.

I know with the Dell 580 and 3010 in the BIOS there is a setting for the SATA. If the 745 is set in ATA for the SATA and you take the HD and put it in another dell whos BIOS is configured for AHCI that will occur with the OS. So if you install the OS with the SATA set on ATA or AHCI the other computer BIOS must be changed to reflect the computer from which the HD came from.
I would start there and check that.
It might also be called Normal and Legacy in the BIOS, instead of ATA and AHCI

The bottom line is that different models are different models. We have a number of Opti-380's running Win 7 Pro. We bought some refurbs Opti-780's and tried to load a clone of the Opti-380's onto the 780. It wouldn't properly boot.
Usually the problem is that there are differences in various circuits (e.g., Northbridge rather than Southbridge), so there are differences in the BIOS. Also, a number of drivers will be different between the two models.
If you can get a basic boot to Windows, Windows might be able to find new drivers, but it depends on how close the two models are. If you can't get a basic boot, you're stuck.
Let's be clear -- differences in basic hardware, BIOS and drivers is a completely different problem than "How do I switch from a hard disk to SSD?"
