I have 4 hard drive:
C: WD40TB current boot up device
D: SG20TB (bootable device because it used to be my C: drive)
E: WD20TB my data drive
The drive "E" above had been acting up, so I bought a new 40TB drive (will call it WD40TB-2 here). I thought it would be a simple matter of taking out the "E" drive above, and install the new drive in the same slot with the same cables, which was what I did this morning. Well, to my total surprise, my PC boots up with the "D" drive above. I re-started my PC and interrupted the bootup, selected to boot from "WD40TB". Well, it didn't matter, the PC still booted with the SG20TB. I repeated this multiple times and kept getting the same results. Finally, I removed the new drive and put back the "WD20TB" (i.e. the original "E" drive). Sure enough, it now boot with the WD40TB, just the way it was before.
Can anyone understand what I did wrong, what do I need to do in order to boot from WD40TB like before (but with the new drive replacing the WD20TB)?
