Windows 10: 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]

Is it possible to reinstall Windows 10 and completely reset UEFI options

In short, I have a dualboot (or did) and I think something went wrong at one point, modifying entries and the like: Ubuntu/Windows 10 Dualboot - Grub missing

I ended up just installing windows over again, but I would prefer to have a dualboot, and figured if I could get the computer to a state in which it first came (BIOS, UEFI and all) I could install it again (as I was able to at some point).

 

One or more network protocols are missing: Windows Sockets registry entries required for network connectivity are missing.

First I'll say I'm on a "Desktop PC" not a "Laptop" or "chromebook" or anything like that. It doesn't have wifi.

So I just installed Win10 then my internet didn't work. Tried searching up every single thing on internet. I did a dualboot now (Windows 8.1 and Windows 10) I did try "Troubleshoot" thing and I got "One or more network protocols
are missing", but it has no option to solve automatically. And the dualboot is totally useless (Windows 10 - no internet connection at all; while Windows 8.1 - Has internet connection and works JUST FINE!)

Okay, I just decided to see advanced troubleshoot details. Updated title, now this is the actual reason. I hope it gets a fix sooner

 

How are they messing each other up? What are they doing?

 

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

 

That's perfectly normal.

 

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? *Biggrin 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.

 

Allright, Squirrel and Obi-Wan Kenobi, always appreciate being able to borrow your wisdom.

hiding partition letter: disk management > right click partition > Change Drive Letter and Paths > Delete letter so the partition disappears for the OS. My concern is if some programs can install stuff to the hidden partitions even if it was hidden.

 

It's not "hibernation" per se that causes problems, it's Fast Startup. When I was first running Win8.1 and the Win10 preview, I kept getting forced CHKDSKs every time I tried to access a shared partition from either OS. When I was running Win8.1 alone, I didn't have such problems.

Then, I read about Fast Startup. This forces Windows to go into hibernation even if you choose Shut Down and when this happens, all open partitions remain mounted, preventing access to those partitions from outside the Windows OS that was running.

There are two ways to disable FastStartup in Win8/10; (1) through the Control Panel, and (2) through an elevated command prompt.

Control Panel - Open Control Panel --> Power Options.
Select "Choose what the power buttons do"
Select "Change settings that are currently unavailable"
At the bottom of the Window, under Shutdown settings, uncheck the box regarding fast startup

Elevated command prompt - run the following command:
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /V HiberbootEnabled /T REG_dWORD /D 0 /F
In both cases, reboot Windows.

You will need to disable it BOTH in Win8x and Win10.

After I did that, I no longer had any filesystem problems.

 

@Cbarnhorst I am wondering why you say this, could you explain please? I have installed both OS's no matter what order and they worked fine.
