Windows 7: Win 7 + win 8 dualboot problem

Win 7 + win 8 dualboot problem

Greetings.
I have Windows 7 on one SSD, and Windows 8 at another SSD. They are both installed seperately of eachother, and as now, I'm switching between then with the Boot-menu in BIOS.

But I want a boot menu, where I can select which OS I will start, so I got the EasyBCD tool, made the settings (I think) and saved it. It is made in the Windows 7 installation.
Windows 7 starts fine, but when selecting Windows 8 I get an error about the file <system>/system32/winload.exe has not a legitime certificat.
If I select Windows 8 from bootmenu in BIOS, it boots just fine. I have NOT installed classic shell or other OS-changing software.

What do I do wrong?

Try using
EasyBCD - NeoSmart Technologies
in Windows 8.

but it IS this program I am using!

I have not changed any advanced settings, just added an entry to windows 8 pro, selected the drive it is installed on, and then clicked "save settings".
What else shall I do?

Theog is suggesting you install Easy in Win8 instead of Win7, to add the other OS. It may work better from the newer OS.

Found the solution. Copied "bootmgr" from Windows 8 to Windows 7 installation, and bingo. It works.
