    Please read what you wrote again. First you wrote that the BIOS is 
the problem and I think that is correct at least in my case. The MS's 
made to support both IDE and SATA hard drives do a poor job of things.

    Then you wrote that Ubuntu is bad. I really think that is stupid 
since the operating system doesn't set which hard drive is first. This 
IS a BIOS function. I have exactly the problem your talking about and 
you must look at what the system looks like with neither hard drive 
active. I do that from a liveCD and that is what grub works with.
