I have 2 SSDs one with W10 (legit) & one with w7x64 ultimate (loader). I never had both disks hooked up when installing the OS's - just the one I wanted to install to. I then connected both, & I added the option to boot either with EasyBCD to my W10 disk. Not so good (Doh!) obviously it uses it's new w10 loader.exe & bypasses the loader boot entry on the other disk. So I get a counterfeit w7 Enterprise msg in w7. One really annoying thing I've noticed that with the UEFI mobo I have, even with the disks set in BIOS to a boot order with the W7 drive first, if I load w10, then reboot, it somehow steals focus from the other drive & goes right back into 10. Hitting F8 for the mobo boot drive selection menu doesn't seem to work - not been able to over-ride & select boot device since w10 went on Cold boot only? I haven't tried using EasyBCD on the w7 drive to add a w10 entry yet as I assume it will try & load w10 with the w7 version of winloader.exe or is that wrong? I'm guessing the BCD doesn't direct the instruction to a specific disk as a GRUB boot manager would... So if I need a boot manager / GRUB Bootloader - These look OK, but expect there are others that can be recommended. OSL2000 BootIt Bare Metal GAG GAG is Free - will Win10 boot from this now old project? For obvious reasons I'd like to hear if anyone knows which would be a good Boot Manager that I can install on my primary drive (with W7+loader), that will let me select either disk when I want.
