Thank you Mike. I have downloaded the Easybcd and it is like you say, but I was standing there for 1-2 minutes and finally didn't click it. I was not ready again for a non starting OS. The operation yes is simple but the "all automatically" is frightening me...
After all it is windows we are...
I did but the previous OS Win7 was on the SSD and so the boot manager located itself there. Now I want to relocate the boot manager to the OS drive of Win10.
I do not want to reinstall from new again the win 10 as I have made all my setting and files and programs and took me almost a month to...
I have had an SSD failing on me so I opted to upgrade to win10 also if I was going to lose my OS (I couldn't clove the drive).
I have made a win10 installation on a different HHD and apparently (I didn't understand it then) the boot manager was still in the old SSD for replacement drive...
I have practical the same issue in Win10. I used the BCDboot command the files were written (it showed) but actually nothing changed. What should I do? I need to remove my old Win7 drive (that is working at the moment) to change it inside the warranty as it has been getting bad time after time...
