Windows 10 & 8.1 dualboot concerns

So i have a dualboot of Windows 8.1 & 10 installed the normal way (device manager> shrink to create a new partition, usb stick etc.) and was wondering if deleting the drive letter of the other OS will be enough to prevent them from messing up each other? If not, can i get clear instructions on what to do? Both were installed on the same SSD (Samsung 500GB 850 EVO) in MBR partitions with BIOS boot mode. Also anything to do about HDD? I disabled hibernation in both OS using cmd commands (powercfg -h off).

Disk0: [System Reserved:350mt][D:233Gt][C:231Gt]
Disk1: [E:1800Gt]

They should not be interfering with each other. Can you be specific about what problems you are having?

I am not having any issues, but was thinking if i should do something before it happens because i can see Windows 8.1 drive when im on Windows 10 and vice versa

As long as Windows 10 is installed second, no issues. If you do encounter something I use EasyBCD2.2 for managing multi-boot systems. I recommend it even if you don't have a problem.

Thanks for answers. Yes i installed windows 10 second. Gotta look into that easybcd2.2. I deleted the drive letters for now so i can't see the other os and accidentally mix something up.

I simply name the drives things like "Windows 10" and "Windows 8." Clever, huh?

Some kind of squirrel humour i don't get? Anyway, thanks all.

Edit: I do have one more question: Now that i can see the same 1800Gt HDD in both OS, would it be safe to partition it in half for them and again hide the partition letter? I mean, if you install stuff that isn't compatible or potentially harmful for the other OS, you wouldn't want it to be there or would it have no effect?

Depends what you mean by hiding the partition letter. If you mean creating a registry key that shows a partition as not available then I suppose so, but that was a maneuver to keep XP from wiping out VSS files when dual booted with Vista and later. I wouldn't worry about something like that with the currently supported versions of Windows.
