Windows 7: (2) Hard Drives wanting two separate Win 7 OS one on each

(2) Hard Drives wanting two separate Win 7 OS one on each

I have (2) internal hardrives in my current pc, what i want to do is install a separate Win 7 OS on each. I have read that you unplug the main hardrive which already has the Win 7 OS on it. And i proceed to plug in the other hard drive, but my pc never allows my to install the Win 7 CD Rom Install disk. I keep getting the "No Boot Device Available error" It sees the hard drive and the CD Rom when I try to click on either i get the No Boot Device Available Error. When both Hard drives are plugged in there is no problems windows boots fine. How can I get the second hard drive to install the CD Rom so I can have (2) separate OS systems on the two hard drives.


I am using a Dell Precision T3500 if that has anything to do with it.

Disconnect the first hard drive from the computer. Ensure that second hard drive is getting detected in the computer.
Then turn on the computer and when you the error message then insert the OS disc in the cd drive( preferable in the top tray if you have multiple cd drives).
Then turn off the computer wait for 5 seconds then turn on the computer and at dell logo tap F12.
When you see an option that says Advance Boot Menu select CD/DVD drive and press enter and then press any key if you get a message regarding press any key.

Is dvd drive working correct? Can you see files in on it in win7?
Did you set the BIOS "boot device priority" or something like that to: DVD, hard disk?

Followed directions exactly and got selected boot device not available after I hit Onboard or USB CD-ROM Drive option
I will verify the cd drive works but I am 99% sure it is
