How to create boot sector on new SSD?

Hi @ll,

I've a running Win10 installation with an old HDD. To speed up the PC I decided to by a new SSD.
I build in the new SSD along with the old HDD. Then I prepared a USB Windows10 installation device for a fresh installation of Windows10 on the new SSD. On the old HDD a Windows7 was ported to Windows10 and hence I wanted to clean install Win10 on the SSD.

All worked well and I configured the new Windows10 to my desires. But now, when i boot the PC immediately after the BIOS tests I get a prompt to choose between the 2 available Windows10 installations.
It seems, that the new installation did not create a boot sector on the SSD but updated the information on the old HDD. Due to the fact, that the old HDD not only is slow compared to the brand new SSD, I also fear, that the old HDD will stop from working anytime soon.
If this happens I will not be able to boot, because it seems the boot record lies on the old HDD. If i switch off the old HDD in the BIOS the PC is not booting due to not having a bootable disk.
I also checked the ordering of the boot sequence which first tries to boot from SSD and then HDD and then USB followed by DVD.

My question now is, how can I write a boot sector on the new SSD so that the PC does not need the old HDD to boot up?
Somebody able to help me with this?

Thanks in advance.
René

    Detach or remove all disk drives so that there is only the problematic drive attached (disk 0).
