Situation: Two operating systems (W7 & 8) on two different HDs.

Problem: If I have booted up and am in W8, what does it mean to "sign in" at the Command Prompt. The form thread I just read gave me a procedure but the step "Signing in" at the Command Prompt from W8 has no meaning to me. Thus, What does it mean to "sign in" at the Command Prompt?
Thanks,
Michael
 
Uhm that wouldn't work. If you put two different HDDs into a computer, one Windows on each, both would claim to the computer 'I am the BOOT DRIVE, load MY OS', which causes a MBR error and causes the machine to erro. You can only have one Windows installed at a time on the HDDs, since Microsoft made some changes with Vista. IF you have a serious need to run two Windows, then you can run the second in a 'sandbox' Virtual Machine called www.virtualbox.org. It will run it inside a session.

As for the instructions, they don't make any sense since the computer would fail, and there is no Command prompt sign on. There is a Sign on at the 'prompt' for Linux? Are they using a hack to run a linux bootmanager which would be different then the normal MBR and be the 'LOAD ME' when the computer starts, then you can 'select' which OS to run on seperate drives, but this is a cludge and if Linux gets in anyway messed up you lose both 'Windows'.
