Host OS: Windows 7 Ultimate x64 on SSD system disk. PC Specs: Intel Core i7 3770K on ASRock Z77 OC Formula with 16GB DDR3, GTX470 VirtualBox version: 4.3.12 r93733 with Extension Pack 4.3.12 r93733.
I've had a Windows 8.1 Pro x64 VM running on VBox 4.3 for a few days now with no issues at all.
However, this morning, the VM refused to boot saying VT-x was not enabled.
I checked via the VM settings but the whole "Acceleration" pane was disabled and not accessible. I was not able to resolve the issue even after rebooting my PC and explicitly enabling Intel Virtualization in the PC BIOS (it was on AUTO before - I set it to ENABLE).
I have since several times removed the VM completely and attempted to reinstall.
Every time, the VM hangs on the Windows 8 logo screen on install and then crashes with the Error 0x000000C4.
As found on VirtualBox community forums and on other sites, I have tried the SETEXTRADATA command via command prompt running as administrator, and have confirmed that the .vbox file has been changed and the string ExtraDataItem name="VBoxInternal/CPUM/CMPXCHG16B" value="1" appended in the <ExtraData> section.
However the VM still refuses to boot or reinstall. I have Ubuntu, Fedora and ZorinOS VM's all working perfectly.
The only change to my system that took place in the interim was that I installed Comodo Free Firewall last night. Seeing the problems I have been having with the VM since this morning, I uninstalled Comodo and rebooted thinking it might have something to do with my problems, but still no joy.
I am also uploading my .VBOX files before and after to show the changes that have been made by the SETEXTRADATA command.
I wanted to play around with Android some and I got this problem when i try to first open up the Android virtual session. I'm not all that familiar with the BIOS. I know how to navigate the BIOS, how to get to the BIOS, and I know it can mess you up badly if you do the wrong thing! (i.e. BIOS drivers)
Created a bootable flash drive using Universal USB Installer from WindowsBlue-ClientwithApps-64bit-English-X1899605.iso. Create completed successfully with 452MB of free space left on a 4GB flash drive.
During install, I get this about 10 seconds after the ugly fish appears during install.
I'll burn a DVD and try it but much prefer a flash drive for install.
Sometimes Windows 8 just hangs after I look around and change some of the DVD related settings in VirtualBox. My host system is ubuntu and the guest is Windows 8.
When it hangs it is usually showing the Windows 7 desktop because I am always in that mode. I cursor to the lower left to try to the the mini-tiles but no matter what I do with the cursor, the mini-tiles do not appear. In fact, nothing works. I cannot launch any desktop applications.
In the past I solved this by simply having VirtualBox send the shutdown power-off signal. Windows is ignoring the shutdown signal. Is there a Windows-centric way to fix this problem so that I can do a Windows-centric shutdown in the normal fashion or otherwise resolve or prevent this problem?
VirtualBox running on windows 8 pro 64bit. I first installed it 2 weeks ago and I had no problems.
At the weekend I decided to set up my virtual machines from my Vista install and some of the older ones didn't work so I decided to uninstall and reinstall VirtualBox.
I checked that the version I had was still the latest version and reinstalled it.
Last night I had problems with my computer hanging at the windows 8 desktop screen for 2-5 minutes before I could open Internet explorer straight after boot up. This was with VirtualBox not running so I presume it's one of the drivers causing the problem.
It seems strange that it was ok until I reinstalled it.
I'm not sure weather to reinstall it again or wait for another update.
I was wondering if oracle virtualbox will run on windows 8 pro 64 bit i would like to use it instead of using the built in one that came with windows as i want to run Tails from [URL] .... in a VM and it is not supported by the built in Hyper-V on windows 8. but i don't want to goof up windows by installing another virtual software so i need to know if it will work before I do it.
I'd like to upgrade from Windows 8 to Windows 8.1 Pro. This will be run as a guest on VirtualBox 4.3.2 (the newest as of November 2013) on Ubuntu 12.04 (April 2012) with weekly updates.
In Windows Store, an attempt to upgrade fails because, it indicates that Windows 8.1 is "not supported by your CPU". This is a doubtful explanation because it runs Windows 8 fine. The CPU is an Intel i7 - 2670 QM that was released in Q4 2011 in a unit that retailed in June 2012. VirtualBox has WDDM and 3D acceleration since at least VirtualBox 4.1 which was released more than a year ago. I run with VirtualBox's display 2D acceleration ON, and previously with 3D acceleration OFF because I've had problems. However, 3D acceleration is presently ON. Regardless, Windows 8.1 will not install either way.
This is what Microsoft indicates under "more information" about Win 8.1.
Processor: 1 gigahertz (GHz) or faster with support for PAE, NX, and SSE2 (more info)RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit)Hard disk space: 16 GB (32-bit) or 20 GB (64-bit)Graphics card: Microsoft DirectX 9 graphics device with WDDM driver
I note that Windows 8 also requires PAE, NX, and SSE2 so that should not be the problem. I have allocated 4 GB RAM and about 500 GB disk, which are both more than adequate.
Edit: I use a 64 bit machine with 64 bit Linux and 64 bit Windows. Edit: Although I tried to install Windows 8.1 with 3D acceleration ON, I generally keep it OFF because it can result in a crash of my .NET application that uses a XAML window. It's not a bug that I care enough about to fix.
How do I fix this Windows 8.1 installation problem?
How to get older O/S's like Windows 95, 98 and ME running on VirtualBox on Windows 8, I used to be able to run all Operating Systems when I had my Vista set up. Strangely I can install and run DOS and Win 3.1 but not Win 95, Win 98 and Win ME. Anything from XP works fine.
I wanted to try the new Windows 8.1 i downloaded virtualbox and downloaded the windows 8 64 bit ISO and it blue screens upon startup what i find strange is i know i can run windows 8 i had the preview iso for windows 8 when it was under development.
I have a strange behavior when I install virtualbox on my windows8 laptop: Cold boot (windows8 restart) will then fail, whereas shutdown (fast boot enabled) or suspend still work fine.
Laptop is an HP G6 with an SSD installed with 64 bit windows 8. Prior to the virtualbox install all three actions (suspend/shutdown/restart) work fine.
If I install virtualbox (simply installing, not creating any VM), then the next restart will trigger an "automatic repair" screen at boot. Will never terminate. Only way to fix is to escape + F11 and restore a previous restore point. If instead I say shutdown (I have fast boot enabled) or suspend, the system will restart fine at next power on or resume.
I have a Hyper-V VM, and during the setup wizard I chose to install OS later.
I added DVD drive to it's hardware, and added the DVD drive to the boot order.
I put the retail Windows XP disc in the drive and start the VM, but it doesn't see the disk and eventually I get the error "Boot failed" for every boot device, and then finally "No operating system was Loaded. Press a key to retry the boot sequence...".
In setup for the VM, I see that I can "Specify the media to use with your virtual CD/DVD drive", which is an "image file". Does that mean it has to be an ISO, not a physical disk?
If so, any good way to make an ISO from my retail Windows XP Pro disk? It looks to me like Windows 8.1 File Explorer doesn't do it.
I am looking into setting up a type 1, native hypervisor on my desktop (Xen, specifically). Would it be possible for me to load my current install into a VM? The hypervisor can be run from a live disk.
I have a Mac running Windows 8.1 via Parallels. What I am trying to do is set up a test 2012 SBS my PC and while trying to connect to my local machine on Hyper-V I get this [URL] I've tried running as admin, I've also tried starting services however I get this [URL]
How to install Hyper-V Manager on Windows 8.1? I can't find anything to say it isn't possible, but I also can't find any way to install it. Anything I have been able to find refers only to installing it in Windows 8.1 Pro, but says the host software requires Pro or Enterprise. However, since I am not installing the host, it looks like it is possible, if you can find the source.
The reason I need to do this is that I have a Windows 8.1 machine and a Windows Hyper-V Server 2012 R2 Core machine, and I would like to be able to access the GUI tools for Hyper-V Manager. This is so I can directly access and see the machines I am running. Right now, I have a machine, but I have no way of accessing it.
I am running Windows 8.1 Pro with Hyper-V enabled. When I had Windows 8 I could install a Virtual switch with out any problems, since upgrading I can not install a Virtual Switch with External or Internal settings.
Not sure if this is relevant or not but when I look at the Ethernet properties never "Hyper-V Extensible Virtual Switch" or "Microsoft Network Adapter Multiplexor Protocol" are ticked. I have tried ticking them but get the error message "Could not add the requested feature. The error is: The data is invalid". I have checked that I am using the latest and correct driver for the card.
Goal: run both windows 7 and windows 8.1 native from VHDX (currently only success with Windows 8.1 on vhdx and win7 vhd)
I have a windows 8.1 installed in the system and rebooted into a command prompt, created a vhdx image, converted to GPT, and then install windows 7 on this vhdx (both with and without KB982018 integrated). The install went through (copying files etc) and it then rebooted itself and finish off the reset of the installation. After it rebooted it the boot menu is the old style black and white (which is fine), and choose win7 vhdx to finish off the installation. However an error comes up - An unexpected error has occurred.
Having no luck therefore instead of installing to a VHDX I now boot up with the win7SP1 USB and install onto a VHD instead. Everything went well and booted into windows 7 (expected). I then install KB980218 and then it rebooted itself, again everything is ok. I then booted back into windows 8, converted the windows 7 from VHD to VHDX and set the sector size to 4096 as per How to Convert a VHD File into VHDX. Boot entry has also been updated to vhdx instead of vhd.
I now try to boot to this new win7 vhdx, and instead of getting an unexpected error, it booted into a graphical screen and ask for repairing the window. (which means it's unsuccessful).
I'm using an AlienWare M14 machine. I tried to create a virtual machine locally using Client Hyper-V on Windows 8 Pro, but it still doesn't work (took me a lot of time). I added the Hyper-V features in "Turn windows feature on or off", and all of the requirements to run Hyper-V are fulfilled (SLAT, BIOS, 64 bits, ...) (I attach the msinfo32 output in this post). At the last step in creating a virtual machine, it says "... General access denied error... (0x80070005)" (for details, check my attached image).
After I installed VMware-player and VirtualBox, I started to get this error "The connection Was Reset" (got that on firefox, different name on Chrome since it has an error code, but leads to the same error).
Weird thing is that I can still explore some of the website that are open, for instance I leave a Facebook tab or Twitter tab, or any other site (not necessarily a social network). But if try to open a "new" site, which is not explored yet, then I get the error.
Things I tried so far: 1) delete cache, doesn't work at all. 2) Change the MTU Value, that was quite interesting, since I do get an error when i try to ping with my current value, but when i find a value that apparently should work, after I set that value as my MTU, I get the error with that value, so i go down a few numbers until i get a working value, set the MTU and error again. and so on. 3) Made a repair of my windows 8 install, preserving my personal files, but didn't work. 4) Only thing that seems to work is restart my pc.
I didn't have time yet to try to reinstall my antivirus (Avast) .
I recently built a rig (spec below) and originally installed windows 7.
I decided today I would install windows 8.1 as I get it for free from my university. I booted the installation disc in EFI mode, wiped the SSD and deleted all partitions. I let windows create the partitions it needs and proceeded to install.
The installation got up to 2% in expanding windows files and showed error:
Windows cannot install required files. The file may be corrupt or missing. Make sure that all files required for installation are available and restart the installation. Error code: 0x800070570.
I rebooted and tried again several times and the same thing happened whether I chose EFI cd boot or not.
I then reinstalled windows 7 without any issues, and downloaded an 8.1 pro disc image from mydigitallife. The installation got a little further into expanding windows files, but the same error came up again.
Ive been reading that it may be a memory issue so i'm the process of reinstalling windows 7 and running memtest86+, but I doubt this is the case as its a mew system and windows 7 has no trouble
I can't install .NET Framework 3.5 no matter what I do. I tried downloading it and in the midway get the error 0x800f0906. I tried installing through DISM but that didn't work either. It always stops at 65.8 %.
I am writing because I wanted to install windows 8 on my pc ... but since it is a Pentium 4 with a 3.2...motherboard ASUS P4C800, motherboard only supports Socket 478 and Socket 478 with no pentium 4 supports specific XD "no eXecute".. there is no way to bypass this control?
Downloaded from Windows.com. Installed and upon final reboot got this error. "The OS couldn't be loaded because the kernal is missing or contains errors." Suggests doing a repair??? by inserting the Disk. Don't have disk, it was a download. What to do next? Is the main file on the HD that I could burn to DVD or??
When I search for updates with windows update it finds the drivers I want but it gives me an error message whenever I try to install them.
I already tried downloading the latest windows update (when I install it, it says the update was succesful and asks me to restart, but when I search again after restarting the update shows up again and lets me install it again).
I also tried deleting and renaming my software distribution folder and using the windows troubleshooting program.
Overall I'm not really too fussed about most of the things it's trying to install apart from the drivers for the wireless reciever for my xbox controller as it won't work without them. When I try to install the driver files through device manager it gives me this error message
my main reason for mentioning the windows update problem is that I assume the problems are linked as the wireless reciever works perfectly on my laptop. Up to about a week ago it also worked perfectly on this computer using the same usb port that it uses now.
As you can see, on the 19th, it suddenly began to say "NULL DRIVER". I checked my system restore and it tells me that I installed a windows update on that day just before it suddenly stopped working. I tried reverting back to this restore point (before the update) and nothing had changed, the device still would not work.
