Dual boot Windows installs completely independent of each other?

Say I want to dual boot Win 10 and Win 7 (I have the license keys), does it matter which I install first? Or Win 10 Pro and Win 10 Home? And to keep things clean, let's say I remove the drive letter from the install that is not active. Will that cause any problems because one install somehow depends on files from the other install?

All the installs would be 64 bit versions. Also, I keep all my "real" data on separate D: and E: partitions to limit the damage from a Windows meltdown.

If it matters I would probably be using EasyBCD to choose the install to boot into.

Thanks,

I would recommend just using BCDBOOT to add the second OS to the boot menu and then MSCONFIG to set the default OS and desired timeout value.

Does BCDBOOT create a menu so can I select which OS to boot into? I would rather take that approach than have to use MSCONFIG to change the default OS every time I want to switch. But it's worth keeping in mind, because I just read somewhere that EASYBCD doesn't really work with UEFI.

Thank you, sir!

You should install windows 7 first, then windows 10 as windows 7 uses an older boot loader, and doing it the other way round can screw up boot sectors.

If you do it this way (7 then 10), it just works.

You can create a dual boot menu, and set whichever you want as default using MSconfig.

You can even set time to choose tombe as low as one second for the boot menu, or even zero in which case other boot entry is hidden until you set a time again.
