what about keeping the 2 systems separate though? will one win7 spy on the other, is it safe?

 

The free version supports everything. It's one of the very few legit Windows tools that I use lol.
Anyway for sure there're several other valid alternatives.

Yes.

Another thing I do is to fully install (including boot "system reserved" partition) the Windows in every drive. This way even if one of the drives explodes I can normally boot from the other without the need of, say, a boot utility.

I don't know how is it arranged with this way of installing (unplugging hard disks). Now I remember I used Aomei ( a Macrium/Acronis like tool) to install to the second drive.

 

Indeed, BIOS has its own boot manager, so you don't need another one.

I manage my XP and Debian that way, actually. Because I don't want any boot managers [GRUB in this case] on the XP partition, so its boot is clean and I can back it up easily. GRUB is otherwise excellent boot manager.

That SATA drive power switch for 4 drives is really cool. I like it.

 

Try Bootit Bare Metal : https://www.terabyteunlimited.com/bootit-bare-metal.htm

It comes with a Boot Manager that allows you to boot any partition on any hard drive (up to 16), including logical volumes and also booting multiple operating systems from a single partition.

BootIt Bare Metal supports hiding/unhiding partitions, swapping of drives, and partition table order for each boot item and will automatically detect existing operating systems upon installation and adds them to the boot menu. You can use the Direct Boot Menu to boot directly to any partition, bypassing the standard boot menu. It also provides options enabling you to customize and secure the computer with user IDs and passwords as well as support for booting to Linux, MS-DOS, OS/2, and more...

 

Testing this utility is in my TODO list since a while...
