Hi, everyone -


I recently removed a SATA hard drive from a slow PC I'm retiring and installed it in a faster PC. This faster PC is running Windows 7 home premium. The hard drive from the old PC is also running Windows 7 home premium. I have licenses for both.


Everything is operating fine. Both hard drives are detected when I boot into either. The thing is, I don't get a boot option menu when first turning on the machine.


So, when I want to boot into the other Windows 7 installation (which has different programs and files on it), I have to F10 into the BIOS, change the boot order of the drives, then restart. It's driving me a little crazy.


When I go to Startup and Recovery in the Advanced System options, I have only one operating system listed in the System Startup menu - Windows 7. However, it shows only one Windows 7.


I figure I probably need to manually add the newly installed drive to the boot manager via bcdedit. However, all the instructions I've found so far seem related to either 1.) adding a different OS… or 2.) adding a new boot option when it's on a partition of the same drive.


I'm trying to do it for a separate, newly added hard drive. Plus, my drive letters are different depending on which OS I'm booted into.


When I'm booted into the original Windows 7 OS (named ENT), this is how my drive letters look:


ENT (C:)


MEDIA (E:) - this is a partition


VOY (H:)



When I'm booted into the second Windows 7 OS (named VOY - and the hard drive I just added to the machine) this is how my drive letters look:


VOY (C:)




ENT (G:)



If I'm booted into the original Windows 7 OS (ENT), what commands and/or lines of code would I enter to add the second Windows 7 OS (VOY) to the boot manager?


Thanks in advance, and I apologize for being so... dense!

Easy BCD is the answer I would pursue.  Link , I suggest you not click any of the buttons which will install something other than what you want.

Great. Thanks very much, Louis! I'll give it a try.
