BIOS Boot problem SSD

[MorgoSTX]

Got a BIOS boot issue I cant figure out...Help please!

• 
  Added a 250g SSD.
  Installed W10 from CD
  With old HDD data cable upplugged, sys boots great from new SSD (fast!)
  Reset BIO boot order, 1-SSD and disabled HDD from boot list
  With HDD connected get error “Insert boot media in selected boot device and press a key”
  Have reset BIOS several time, disabled DVD and HDD from boot list, but if old HDD is connected it will not boot from SSD...yet.
  
  Thoughts?

Sometimes (what MoBo?) a "new" detected drive just confuses the BIOS.
You may try to switch the drives on the physical Sata-ports of your MoBo.

Can you post screenshot from Disk Management?
Most likely bootloader is located on HDD (not SSD). You should always install windows with only OS drive connected.

SkyNetRising is right.

Update: After like 6-8 reboots with same config (double checking settings), it started booting from SSD, but would not recog the HDD, after several more reboots, it finally behaves as desired. Now copying files/docs/pics over to SSD, and will eventually reformat HDD, once reasonably confident I not missing anything critical.
THX for feedback.
