Adding W10 entry from W7 bootloader fails!


New Member
Hello, i got W7 installed on a drive & W10 on another. From W7, using EasyBCD 2.3, i just add my W10 partition to the bootloader. However when i try to boot it, it fails! Not sure what's happening..?

You can't boot a newer version of windows using an older bootmgr. (invalid digital sig - the old bootmgr thinks the newer winload is a fake because OSs aren't forward compatible)
Boot W10 and add W7 to its BCD.
Always use the newest version of Windows to control the boot (even if you normally use W7 rather than W10)
