Hi,

I have a computer that has been running Win 7 Ultimate x64 on it's own GPT SSD for a couple of years.
I recently got another SSD and installed Win 10 pro x64 on the this MBR initialized SSD.
My UEFI capable BIOS has a number of boot options relating to GPT & MBR, the one I've chosen is GPT first, then MBR.

After doing this I don't get any dual boot menu selection - but would like to.

How do I get the dual boot menu without corrupting my Win 7 installation - or secondarily the Win 10 installation?
Can EasyBCD 2.3 fix this?

Thanks for any advice,
John

PS: the reason I installed Win 10 on an MBR disk is because when I attempted to install it on the SSD formated as a GPT disk the Win 10 istallation refused to install, saying it couldn't install on a GPT disk.
 
You will need to boot the W10 system and add an entry to its BCD for W7 (point to the partition letter which W10 sees as the W7 partition)
Adding Entries
You cannot do it the other way round. Older versions of bootmgr are not compatible with the digital signatures of newer versions of Winload.
