[NAME]  You will have to remove the boot drive and put the new drive in its place and reinstall clean.  Then put old drive in a dock to recover data.  Putting 2 bootable drives in will confuse windows so the old drive will need to be formatted as EXFAT so that it will not split drive letters across 2 drives and make the BCD invalid.  Or leave the second drive in place and use disk management to partition and format it as exfat so that you can store data on it.
