I've wanted to install docker on my windows. I'm getting an error. Hardware assisted virtualization and data execution protection must be enabled in the BIOS. See . I can't go to my bios, after pressing f2 i have just a black screen, i tried to restart my computer manually and from windows in advanced settings from tutorials. In task manager my virtualization is off, I checked my Cpu supports virtualization on Intel Processor Identification Utility and it is. My Cpu is i7 4770k 3,5Ghz. I downloaded bios update for my motherboard but I know, I have to put it on my Pendrive and open it from my bios, couldn't install it straight from my pc with .CAP extension. My motherboard is Asus Z97M-PLUS. I tried to set my virtualization without bios with tutorials, PowerShell commands, changing settings, avast, hyperV. Can't describe exactly what I was doing and which commands I was putting in because I tried everything I found.
It is difficult to help you in this case as this is a very case-specific problem, especially hardware specific. The fact that you can't enter your bios will make enabling virtualization very difficult, as this switch must be switched there, and only there. I suppose you could try resetting your BIOS by shorting two pins / pressing a button on your motherboard, to see if that makes it want to open again.
Try this motherboard manual document at section 1.2.6 and 1.2.7 depending on your use case.
Furthermore, this website probably is not the best place to ask these sort of questions, and tech forums would probably be better able to help you further.

ive got a sony vaio duo 13.
ive gone into bios using the assist key and enabled intel virtualisation tech setting. The emulator stll doesn't work.
all programs run from this site have returned that it supports hyper v but that it is not turned on?any ideas?

The answer was not exactly obvious. After reading everywhere about intel trust execution needing to be disabled, I decided to attempt to disable anything to do wit bitlocer. On my specific hybrid, there was a setting labelled "secure boot mode", there were a few options here but I tried to just disable it. Hey presto that was the sucker. I hope this helps someone else.
Edit::
Above answer was actually incorrect. If you change the bios setting on my laptop, then shutdown and start up. nothing happens. if you then restart the computer a whole load of hardware fails, butttt intel VT works finally lol. It must have been dumb luck it worked before. But the shutdown/restart combo works predictably. Unfortunately it totally knocks out some of my other hardware (touchscreen, key lights) rendering this entirely freaking useless :(
There seems to be an odd issue with Hyper-V on AMD machines and the Microphone In. As developer I installed Hyper-V for the usage of the Windows Phone 8 SDK. A side effect is that the Microphone In since then is not working anymore - lots of static noise.
You can of course turn off Hyper-V as Windows feature or go to the BIOS to deactivate conditions which are necessary to use Hyper-V. After that the Mic In is working again.
Most solutions in the Internet suggest turning of the BIOS features but that doesn't really works, because then you cannot use the Hyper-V.
Is there any solution to this problem? I do need both at the same time.
I had a similar problem with audio playback couple years ago (Windows Server 2008). The problem was that my system did not support Second Level Address Translation (SLAT). Therefore the Hyper-V layer needs to work harder and discard the CPU page tables when swapping running OS. That causes jitter in anything that requires real-time processing.
I believe that Windows 8 requires SLAT to enable Hyper-V (see this). You probably have a different problem then. Perhaps there is a better driver available for your audio hardware?
I've got an old 16-bit application, that was developed for Windows 3.1. It preforms some calculations and is part of a more complex system. The system sets up the inputs for the program, and collects the output results.
Unfortunately, the 16-bit program is here to stay for the mean time, so we have to work around the frustrations it causes on modern operating systems.
The system runs on Windows XP, and on physical Windows XP machines it runs alright. The machine I'm having a problem with, is a Windows XP instance running on VirtualBox (version 4.1.12) on a Debian box. The physical computer is an HP Proliant server, with Quad Core Xeon 3.4 Ghz. I'm using remote desktop to access the computer from my Windows 7 box.
The error I'm getting is, "PROGRAM caused a General Protection Fault in WIN87EM.DLL at address : 0001:02C9". The annoying thing is, at times it works and other times it doesn't, making troubleshooting all that more frustrating.
From trawling the internet, I've come across a few sites that mention the same problem. None of them seem to offer real solutions, except to say that WIN87EM.DLL supplies floating point routines, and has some issues with certain printers.
I've uninstalled all printers on the virtual machine, I've also tried installing a PDF writer and setting it as the default printer - so that there is a printer on the machine. I've disabled resource sharing with my Remote Desktop connection. I've updated the Virtual Machine Guest drivers on the machine. I've also tried setting the compatibility to Windows 95 in the properties of the executable.
Any pointers for troubleshooting this problem, or methods I could try to get it working?
This question is old but I had this exact win87em.dll crash with some 16-bit factory automation software running natively on windows 7. By following the method of HIDE87.com and editing autoexec.nt I was able to make the software stop crashing so that I could make edits.
This machine was running Intel 8 Series/C220 Series chips. I attribute this configuration to the crash because I have used this same 16-bit software on tons of other windows 7 machines for years now.
edit: here's the steps I used to fix the problem
Download winfloat.exe from http://www.conradshome.com/win31/archive/
Open winfloat.exe with 7zip. Find HIDE87.com and extract it to desktop.
Copy HIDE87.com to C:\Windows\System32\
Open c:\windows\system32\autoexec.nt with notepad
At top of file, after first group of comments add the following

REM Fix for Gen. Protection Fault in win87em.dll
Save changes to autoexec.nt and reboot pc.
This was the same error I had with Microsoft XP Mode.
Obviously WIN87EM.DLL has Problems with virtualized processors.
My Solution: I "unloaded" the XP-Version of WIN87EM.DLL in the registry (search and delete every item with this name), and copied a much older version into application folder. The old version can be found her: http://support.microsoft.com/kb/86869/de
Good luck!
Video Driver win87em.dll
This is the step by step resolution to the problem we had with the “win87em.dll” issue.
Left-Click the START button in the bottom left corner of the screen.
Right-Click My Computer and left click Properties.
Left-Click the tab at the top that says Hardware
Left-Click the button that says Device Manager.
Left-Click the + sign next to Display Adapters near the top of the list.
Right-Click the items shown in the expanded list under Display Adapters and left-click Disable.
Left-Click the Yes button that shows when windows asks if you are sure you want to disable it.
Left-Click the No button when windows asks if you want to reboot.
Repeat the disable process for each item listed under Display Adapters (usually only one or two)
Reboot the PC and the win87em.dll General Protection Fault errors should go away.
This is only applicable for users on Windows XP. Most likely the display adapters listed will be shown as an Intel G41 internal display adapter, but it may be another Intel device. If this does not fix the issue then it is likely a bad printer driver causing the problem.
Disabling the video adapter will not hurt windows. It will make their computer unable to watch videos or play 3D games, but windows will still run and look fine. (They will probably need to change their screen resolution after rebooting.)
VirtualBox 4.3.16 should also have a fix. See https://www.virtualbox.org/ticket/12646 If you want the fix immediately, you'll have to build VirtualBox from OSE sources.
Update: VirtualBox 4.3.16 containing this fix is now officially released.
I know this is an old thread but I came across it while searching as I was having the same issue under Windows XP running VirtualBox. Eventually I found the following:
https://communities.vmware.com/people/jmattson/blog/2012/03
This is for VMWare and seems to have fixed the issue, couldn't find anything similar for VirtualBox but as VMWare Player is free it is a good workaround for anyone having this problem.
in the case of virtual machines - vxBOX (tested) of VM ware (maybe)
you just have to switch off all para virtualization options in the processors section of VX BOX options.
works like magic!
Is there any way to programmatically disable Turbo Boost on a Core i7 mac running Mac OS X ? I need to be able to do this for benchmarking purposes during code optimisation etc. Failing that, any kind of utility which can disable/enable Turbo Boost, even if it requires a reboot, would be useful.
There is a related question (not Mac-specific) on SO: How to turn off Turbo Boost temporarily? but even for PCs it seems that there may be no way to do this programatically/on-the-fly ?
I wrote kernel extension that let's you disable TB, have fun:
https://github.com/nanoant/DisableTurboBoost.kext
If you want to disable TB on Linux here another recipe: http://luisjdominguezp.tumblr.com/post/19610447111/disabling-turbo-boost-in-linux
I've just coded an app that allows to load / unload the kernel extension mentioned before, helping to track the system behaviour displaying CPU Temp & current fan speed.
You can check it out here https://github.com/rugarciap/Turbo-Boost-Switcher
Here is an screenshot of how it looks like http://i.stack.imgur.com/tsKaG.png
You can't. Certain stuff needs to be configured from the BIOS, such as TurboBoost or Vt.
In particular, this is done with the IA32_FEATURE_CONTROL MSR. On a PC, at boot time the MSR is unlocked and the BIOS sets the correct bits to enable or disable features. Once configuration is complete, the BIOS locks the MSR for the changes to take effect and prevent future modification.
I don't know if it's possible to unlock the MSR again before the PC is brought into protected mode, and I don't know how this works on a MacBook where EFI is used instead of BIOS. You'll probably be able to pull it off with an EFI extension of sorts.
CPUID.com's Tmonitor utility can disable/enable Turbo Boost on-the-fly from within Windows, not at boot! There must be a way to do the same thing from within OSX.
Finally there seems to be a good solution for this problem which I have tested with Mac OS X Lion on a Core i7 MacBook Pro today and it appears to work well. Adam Strzelecki, a researcher in parallel computing at Jagiellonian University in Krakow, Poland has written DisableTurboBoost.kext - this is a small kext which can be loaded and unloaded at will (via the command line) to disable/enable TurbBoost.
I'd like to ask anybody who has built a virtualized VS2010 environment in VirtualBox or VMware, which one was able to work out of the box without too much tweaking? Or both need workarounds to get stuff working?
Both are fine as long as you install the respective tools and drivers provided for the guest OS
If you're using VMWare Workstation, you can leverage even more out of the environment by installing Visual Studio on the Host PC, and using the Guest VM for debugging, if your application crashes you can actually rewind back to before the crash and step through your code with the same heap and stack before it crashed!
Basically, I suggest going with VMWare Workstation. It's pretty cheap (assuming you get paid to program) and has many, many awesome features that you'll come to love. If you're a hobbyist/student programmer however, you'll likely find VirtualBox to be a little more functional than the free VMWare Player.
As far as performance goes, Intel and AMD both have shipped chips with hardware virtualization since 2005/2006 respectively. This is called VT-x or AMD-V, and often has to be enabled in the bios on older machines.
Basically this means that your BIOS handles Memory and I/O virtualization on this chip, while specialist drivers (e.g. VMWare Tools) are installed to improve graphics and mouse performance - effectively this means the resulting VM has near native performance with minimal overhead.
Hope that helps!
You can work with a VS2010/Windows virtualized environment with no problems.
I've worked with such combination and I had no problems. Both VMWare and VirtualBox are stable so far since years and Windows OS virtualization works properly.
Obviously, you can have performance loss, because a virtualized OS has more bottle necked access to resources than a host one, but current CPUs from Intel and AMD have advanced virtualization instruction extensions which accelerates virtualization operations.
So... Just go ahead!
I don't know your requirement but there is also a great alternative using Win 7.
You can create a vhd file and boot on the vhd file.
A few steps more, you can create a base vhd file with everything you need, mark it as readonly and create as many differential disk as you want.
The drawback of this method are these ones :
it's a bit tricky to create the base and diff disk, because you have to do it in the setup console of windows setup (but google can help you)
there is a small performance impact on the disk I/O (but lower than the visualization environment)
you can run only one system at a time. In fact, nothing disallow you to install a virtualization software
you can't have your "host" and it's potential tools (corporate email, etc.)
but at least, the performance will be greatly better than a virtualization software.
