BIOS ignores desired boot priority/order/sequence

When I connect a second HDD, and reset the BIOS to boot from the SATA socket to which THAT HDD is connected which I want to boot from, booting may still happen from the other socket/HDD. How can the BIOS setting be enforced ?

 

Was the drive you are trying to use have a version of Windows installed in this pc, because if not its possible the pc cannot boot to it because there is different hardware on it so the bios is passing it
as unbootable...are you certain in the boot order you have the correct drive designated for the drive you want to boot to. Remember the lowest the number of the sata port is the one you use for the boot drive or the drive you want to boot to. One of the easiest ways to tell that would be to unplug the drive that is booting now and see if the system finds the other drive and boots to it.

 

That's good advice,Rich.

Finally found out what OP is trying to do and that is clone his OS or portions.
He is using a paid program called Casper 7 and that program is full of issues.

Been reading up on "Casper7" reviews.
Here is one quote.

QUOTE
"They have a known problem in ver 7. If your source drive has problems, Casper will not know and try to mirror to the destination drive. The mirror will fail, rendering the destination drive in a RAW [unformatted]state, thus killing any data already on the destination drive [your prior backup!!!]"

UNQUOTE.

 

Interesting Dougie I have never even heard of that program but again we both know there is no way to solve anything unless we know all the facts.

 

Hum, considering the OP seems to be obtaining a lot of help on the other forum, some from Dougie, some from me, and some from others.

However as I read it now, he has two hard drives, both of which have Windows 7 installed, in both cases each is naturalised to the computer they are in, just so we understand that.

He then says he has altered or tweaked in some way one of the drives, what he altered is as yet not clear, however I think that in itself may, or may not be a part of his problem. However his real purpose seems to be that he wants to clone over these tweaks or alterations to the other drive in some way, without disturbing the second drive very much.

Also, the time zone differences are making things drag out a little as Dougie is the only one around and awake at the same time, being both are in Sydney.

However if he does come back to this site, we do at least have at least a basic idea of where he is at the moment.

So Sebastian, if you do come to have a look back, other folk here may be also able to help further if required, however some more and deeper explanation of exactly what you wish to do and why will be helpful to us all.

You are right,Cindy.

Correct to your scenario.
Yes, Win8.1 was installed on both HDDs in the same PC. I have PROOF that if Win8.1 is installed on another PC I have, THAT HDD will still boot in THIS PC. I expect it's a co-incidence, and can not be generalised to a Win 95 situation (pre-NT).

In case you're intrigued why I would have two HDDs with Win8.1 installed in the same PC connected simultaneously, it's because I have altered one and want to synch (I think it is called) the other, by cloning it from the altered one.
UNQUOTE.

At no time it has been revealed what has been altered. I can't see a problem in this cloning if both HDD's OS's will boot into Windows at the moment on this Computer. When done I would use "EasyBCD" which will give you a boot option to whatever desired OS on boot..
