I am running Windows7 and I've installed another HDD on which I've installed Windows10. I had to disconnect the HDD with W7 on it as the W10 installer just wanted to upgrade my W7. this means that MS config in W7 just sees W7. I tried easyBCD but it also just sees the W7 installation and when I point to the W10 drive it just adds another menu after the startup in the bios. I've searched for a solution but none of them seem to work.

Is there a way for a simple choice to boot between the systems without having to keep waiting at startup with F8 pressed. Another irksome problem has arisen where bios? keeps wanting to check the 3rd HDD for problems even though I did let it check once.

 Since posting the above I've now got more problems with the BIOS

I've disconnected my W10 HDD just so that I can use my computer normally on W7, however I cannot get the bios to just boot to my W7 SSD. I now have a choice of Atapi (?), Samsung DVD (which was the CD rom I installed W10 from), WDC HDD (which is a data only HDD), Samsung SSD (Which is my W7 SSD) & a USB storage HDD. Once I get past that hurdle I then have to choose between 2 W7 Entries.

How can I get back to normal, ie remove all of these additional choices
Another problem which will have to wait. Went back into W10 and when it eventually booted up, after updating, my Bluetooth keyboard and mouse are not recognised so looks like I'll have to start reinstalling W10 again after I get this BIOS sorted

So if I understand you correctly you're using the bios's boot manager F-key to select which device you want to use and then thereafter selecting one of two entries to boot into Windows? Inside the bios you can change the default boot order and put your SSD at the top of the list or second from the list and cdrom is first. Making a mistake using EasyBCD or bcdedit you can break things really fast. You can go about this in different ways. Delete the extra entry using Easybcd or bcdedit (taking precautions) If you can boot into Windows then go to run and type msconfig under boot tab you should see both the entries there. Be sure to not delete the one that says Windows 7 (C:\Windows) : Current OS; Default OS. If I recall the current one will probably will be grayed out and you cannot delete it anyways. That should fix the problem. If you're on Windows 10 same thing it may say Windows 7 you can change it.

 

I am not sure if you are trying to upgrade that windows 7 to Win 10 and then keeping that same Win 7 on a different HD as well. You cannot do that once you upgrade Microsoft will likely deactivate it. You probably will get away with it now, but later down the road you may not. Reason it works now is that Microsoft allows people to roll back to Windows 7 as people have not totally comitted to Windows 10. Unless you are installing retail along with W7. IMO Windows 10 is better even though we gotta deal with all this spying bs. Don't think that by having Windows 7 you're immune lol. All Windows version are being spied upon. Even in the linux world. Oh and before you edit the bcd make a backup first. Run cmd as admin and type: bcdedit /export c:\bcdbackup to import it you just bcdedit /import c:\bcdbackup
