I'm having the exact same problem. I've fully formatted my hard-drive and it still says it's a "windows to go machine". When I plug an External or a USB into my machine and then unplug it, it crashes. So annoying. Someone find a solution, please?!

Follow these steps to delete the Windows To Go registry value:
- Open regedit.exe
- Browse to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
- Delete this value: PortableOperatingSystem
You will most probably notice that the issue reappears when you connect a particular USB drive to the PC. Subsequent removal of that drive will cause the PC to crash. This is happening because the unique IDs of the USB disk and the internal HDD are the same. The easiest way to fix this issue is to "clean" the disk. A clean will destroy all data on the disk, so back it up first.
- Open diskpart.exe
- Type "list disk" to determine the disk number of the USB disk.
- Type "select disk #", where # is the disk number you determined.
- Type "clean".
- Type "exit".
Restart your PC. You can use diskmgmt.msc or diskpart.exe to repartition your USB drive to resume using it normally.

How in the world does Windows 8 wind up thinking that the internal drive and the USB drive have the same Unique ID??? That kinda seems like a MASSIVE flaw. MS is going to have a major problem on their hands if this starts happening to people. I NEVER set my computer to be a 'to go' computer.
How do I determine WHICH usb drive/device is the same?? There's got to be a way to find this out.

Uh I'm having this same issue today after charging my Nook device using my newly upgraded Windows 8 laptop. This is a huge flaw! All seemed normal until I unplugged the device from my laptop last night after charging was complete and Windows crashed. Now today I can't access the "store" because now my laptop believes its a Windows to Go device.
-
I don't know if I did or not. Whether I did or not, this is a massive flaw and there needs to be a way to put it back without rebuilding it. Masking it with Rahuls answer worked, but I just know it's going to come back to be a problem at some point.

I have NO idea what made my Windows 8 Pro believe it was set for Windows To Go, which I thought was for Windows 8 Enterprise and that you have a bootable USB3 device, none of which applies to my configuration. I have a USB2 Readyboost stick and my Windows phone is connected via a USB2 connection. This issue has really set me off.

Steps to determine the disk unique ID:
- Open diskpart.exe
- Type "list disk" to determine the disks in the system.
- Type "select disk #", to select a disk.
- Type "unique disk", to view the unique ID of the selected disk.
If you are consistently able to reproduce the issue with a particular USB device, use the above steps to determine if there is a disk collision.

Deleting that reg key fixed!
Now I have an idea on why this issue happened. I did a Complete PC Restore to another drive. Then I attached my other drive containing the same OS through a USB interface (in order to wipe it). I imagine that a disk collision, see here, took place and made Windows upset.
Anyways, much more at ease now that I can run a system image backup again :D

Hey Rahul,
Almost correct. Here's what I did:
1. Perform complete PC backup of hard disk A to another disk B
2. Restore backup image on B to another disk C
3. Connect disk A via USB to a system running off of disk CDoes that make sense?

@Michael Faklis, are you hitting this issue again when you use your ReadyBoost drive and/or Windows phone?

@TanyaMS
After following the instructions posted above to delete the registry value, does it reappear on connecting your Nook?

I haven't had a reoccurrence. I did follow your advice and cleaned all of my spare disks.
I do have a 2-drive USB3/SATA caddy which I use for backups drives. I remember backing up a drive I was having problems with and then doing a restore to another drive. That was a month ago, and the problem I encountered was just a few days ago.

There is not need to CLEAN any disk!
You can simply plug the USB drive that has the same unique id of your internal drivers and that is causing the porblem, and use diskpart to change its unique id:
- Open diskpart.exe
- Type "list disk" to determine the disk number of the USB disk.
- Type "select disk #", where # is the disk number you determined.
- Type "unique disk id=XXXXXXX"
- Type "exit".
replace XXXXXXX with a valid unique id. I got the internal drive unique id and incremented the value by 1 (it was 21454B89 and used 21454B8A for the usb drive).

hi Rahul!
in my case the problem is, that there's no such a value as "PortableOperatingSystem", i checked the unique id of the drives and they are different (my old hdd connected via usb). I still can't create a disk image or access windows store, because it says that it's windows to go version (but it's not - it's windows 8 pro in fact) although it's my internal and the only ssd drive

I have the same problem. There is no "PortableOperatingSystem" value in my computer's registry. -

Are you sure? Try running:
reg query HKLM\System\CurrentControlSet\Control /v PortableOperatingSystem
Rahul, hi again. I think you've been somewere abroad because it took you quite a long time to answer.
But anyway, for everyone whom rahul's reply wasn't enough i've got to say i found the solution (based on what rahul wrote but not exactly).
so the most imprtant thing is, that there can be a situation that there is no value "PortableOperatingSystem" (on a path that rahul and your comd promt indicated). then, you should go again to regedit.exe and then (while you are still in regedit.exe) type the shortcut ctrl+f, or you can find that option also in the upper left corner in "edition" or something like that, next to "file". i found one value containing HKLM\System\CurrentControlSet\Control /v PortableOperatingSystem and i deleted it. turned the computer off and on again, but it didn't help (still coudn't access app store and so on), so i entered regedit.exe again, and i searched (ctrl+f) for it again. this time value PortableOperatingSystem looked different, but i deleted it anyway. turned the computer off and on again, and at last i did. now i can create disc image or access app store.
the end of story. i hope it will help someone.

This last solution worked for me. Had installed w8 on laptop and netbook with usb drive and kept getting an annoying notification that "backup not available in a portable workstation environment". However after finding "portableoperatingsystem" with the registry search, deleted same and now all ok. Notification no longer appears and also I can backup. Many thanks. FYI Rahul, the path you gave to "portableoperatingsystem" was not in my system w8 pro.

Rahul, regretfully no since I deleted it.
However on using the procedure posted by windows 8 user 1, it brought it up as he stated.
Could be it was "HKLM\System\CurrentControlSet\Control /v PortableOperatingSystem but not sure. the "v" seems to throw things.
This solved the problem on two systems mentioned in my post on the first deletion without the restart and second deletion.
none of the diskpart options worked.

Same problem. As best as I can remember this is what led up to the problem:
1) Upgraded from Windows 7 Home to Windows 8 Pro.
2) Used "Intel® Data Migration Software powered by Acronis" to clone HDD to SSD.
3) Installed SSD.
4) Booted Windows 8 Installer from flash drive to Automatically Repair, a couple of times.
5) At one point noticed PC booted into System on SSD but with USB marked as Active partition.
6) Would not boot from USB flash drive, missing file.
7) Booted fine from SSD.
8) Found error reports that I'm running windows to go, and functionality is restricted.

In point (5): Do you mean you saw "Active" on one of the USB partitions in diskmgmt.msc? That is expected, because your USB drive is bootable. It would be surprising if you also saw "Boot" or "System".
Once you cloned your HDD onto your SSD, did you ever connect both the drives to the same system, maybe using a USB enclosure?
-
Chris, have you tried the previously posted solution?
This worked on two separate systems for me
quote
you should go again to regedit.exe and then (while you are still in regedit.exe) type the shortcut ctrl+f, or you can find that option also in the upper left corner in "edition" or something like that, next to "file". i found one value containing HKLM\System\CurrentControlSet\Control /v PortableOperatingSystem and i deleted it. turned the computer off and on again, but it didn't help (still coudn't access app store and so on), so i entered regedit.exe again, and i searched (ctrl+f) for it again. this time value PortableOperatingSystem looked different, but i deleted it anyway. turned the computer off and on again, and at last i did. now i can create disc image or access app store.

Tank's for your help.
I have deleted "PortableOperatingSystem" (value = 1) and, now, my pc run without any problem (don't crash when use an USB external HD).
The key was located in "HKLM\system\Controlset001\control\" and "HKLM\system\CurrentControlSet\control\".

Hi, there.
The Windows Team has released an update on Feb 12 that will prevent the Disk ID collision, so anyone who installs the update and get an ID Collision after that, will not have this issue. However the update will not fix the problem to anyone who is facing it in this moment. They will have to clean the disk and delete the PortableOperatingSystem key as Rahul described.
So go to Windows Update!

this method
- Open regedit.exe

- Delete this value: PortableOperatingSystem
works for me but i don't delete just change dword value from 1 to 0 :) tnx for your help i can access my windows volume disk from ubuntu :)

I had the same problem.
Removing the PortableOperatingSystem value fixed it.
In my case I think the thing that caused this bug to hit me was I upgraded my motherboard the other day. I had to call MS support and re-do product activation. I think this happened as a result of the activation step.
Note that this problem also appears to cause the Windows 8.1 setup disc to prevent you from upgrading from Windows 8.0. Before I fixed this (removing the reg value) I could not upgrade to 8.1; setup told me I could not upgrade a USB disc!

I just tried to update my desktop on Windows 8 Pro to windows 8.1 . My computer thinks it W8 to go and won't complete the install .. annoying having waited a while to download the 3.5 GB file . I tried your regeit suggestion but I do not have the PortableOperatingSystem value
Do you have any suggestions ?
-
As far as I can tell, this nuisance popup started when I tried ( unsuccessfully) to upgrade to 8.1.
Anybody else notice the bloody message has a typo:
This feature is not AVALIABLE in a portable workstation environment.
HP ENVY dv7. I also cloned the HP disk to a Corsair SSD, using their software.
Placed the original drive back as a secodary disk in the machine.
Win8 prevented me from formatting it first ... but it has worked fine ( until now )
Removed the PortableOperatingSystem reg key ( Thanks ) -

I've got the same problem - I'm running Windows 8 Pro. I've checked the registry, and there is no HKLM\System\CurrentControlSet\Control /v PortableOperatingSystem. Nor in the ControlSet001. I've searched and there is no entry for that path. What now? I want to upgrade to 8.1, but can't because of this stupid problem!

Well i just had this happen after upgrading to the windows 10 upgrade 15056 or so.
i was using Acronis 18 to make a clone for a backup and it crashed.
I did a search in the registry and deleted the whole line PortableOperatingSystem.
Fixed mine.
So no more clones for my .
Backup works for me and the store works i deleted all partitions on the portable drives i were trying to clone to.

Thank you for posting Rahul Ramadas. Your advice explained my problem and told me how to fix it. My SSD C drive switched to a portable drive after I cloned it to a much larger SSD (I was upgrading my OEM SSD because it was running out of room). Then when I tried to backup the OEM SSD I could not because Windows thought it was on a portable drive (The unique IDs being the same on the internal and USB SSDs, like you said.) Followed your steps and resolved my problem. Thanks again!
