Windows 7 Virtual PC: "Cannot Attach The Virtual Hard Disk ..." Error?
Sep 6, 2012
Got a new Windows 7 Enterprise 64 bit machine, found that it did not come with virtual PC. Downloaded the critical patch Windows6.1-KB958559-x64-RefreshPkg.msu and installed it. Windows Virtual PC shows up in my Start Menu. Good so far. I go through the steps to create a virtual machine and use the option to 'use an existing vhd file' and when I click 'Create' I get the above pop-up message "Cannot attach the virtual hard disk to the virtual machine. Check values and try again". A factual message but completely useless as with all error messages from Microsoft. I have tried the following:1. When I attach that vhd using Disk Management, it mounts in drive E:, I can see the files and browse the dirs in E:. In the Disk Management View, the drive shows up as 127 Gigs but 107 is unallocated space. The physical size of the vhd is only 25 Gigs2. Others in my company were able to create the virtual machine with the same vhd, checked the byte size and timing, so nothing is wrong with the vhd file itself.
3. Tried to create after shutting down all virus protection including the Micorsoft antimalware protection service. No luck4. Tried Vhd resize to resize the vhd to a smaller size (since it showed up in disk management as 127 Gigs, I thought maybe it was that size), but VHDResizer could not open the input file, gave an errors "Can only load fixed or dynamic drives"
if there is a way to open the Command Prompt during Windows XP installation (booted from CD) and find a way to attach a Virtual Hard Disk so you could install XP on it (just like with Windows 7 and 8)?
I have Win 7 Professional x64, and whenever I attach a USB device (my mp3 player, to update its firmware), it installs the drivers needed, then after about 30 seconds automatically detaches (that is, it is shared and auto-reattaches to Windows 7). I have uninstalled and then reinstalled XP mode, uninstalled and reinstalled the Virtualization drivers, and tried using different USB ports. how to make it stay attached until XP Mode is hibernated?
I run Win 7 64 bit with Virtual XP. I loaded HP 5400C software into Virtual XP. I attached Scanner and was able to scan/print and scan/pdf. ie everything worked as it should. A week later Virtual XP requested I run 7 updates. Since 7 updates the Virtual XP sees the scanner. When I request "attach" it goes ding dong. When I check again the wording does not change to "release" I think the problem lies with the recent updating. The scanner software reports the scanner can't be found.
first time installer of an SSD here! I'm extremely excited to pop this bad boy in mainly for a faster overall boot of my computer. Recently, my friend gave me his Crucial M4 64GB SSD, which I am very thankful for. I plan mainly to put Windows 7 64-bit on it and that will be all. I was reading this guide: (SSD - Install and transfer the Operating System)
Once I opened up the command prompt, I did all the processes stated until I got to, "Clean" for whatever reason, after typing in the command a prompt came up that stated:
"Virtual Disk Service Error: Clean is not allowed on the disk containing the current boot, system, pagefile, crashdump, or hibernation volume."
So, what I'm asking is there anyway I can bypass or fix this problem so I can continue the process of putting Windows 7 on the SSD? And another question is, would it really be worth buying the $20 program that the guide offers?
I have been trying to install windows 7 but when I select the partition to install it says something like that "it has current MBR partition table ..on EFI systems windows can only be installed on GPT"While following the above instructions and using "OPTION 2" I get this error when I type "convert gpt" "Virtual disk service error"
I upgraded to Windows 7, but I have a few software I installed on Virtual PC 2007 before. I use XP mode but can't find a way to use the virtual HD created with Virtual PC 2007. Is there a way to convert the virtual HD so that XP mode can recognize?
I want to open some old files on an old external NTFS hard drive formatted in WinXP on my win7 laptop that recognises but rejects the old XP-formatted disk as an "invalid disk".
Rather than installing XP on the laptop as a dual boot along side Win7, I would like to know if I install XP-mode Virtual PC on my Win7 laptop will I be able to open my XP disk from within the XP-mode Virtual PC?
Virtual Disk Service often stops working in my notebook HP G60 125NR.the dependencies PLUG-N-PLAY and REMOTE PROCEDURE CALL are running.Without VDS, my Notebook does not recognize many USB devices and USB HArd Disk.HOW TO ENSURE THAT VDS DOES NOT STOP? Or. HOW TO RESTRART IT?
I'm trying to install 7 on a VHD using the command prompt. Now it does work but the problem is that it installs 7 Basic when I do it like this. I have Professional. Now I can use the Anytime Upgrade and use my product key to get Pro activated but because I'm in basic, 7 won't work on the VHD at boot. When it asks for my product key upon first time setup, it doesn't work since it's looking for a Basic product key.
Is there a way to get 7 Pro on the VHD through the CMD?
Does Virtual box write to the disk or does it contain it within your host operating system?
I have tried to understand it but can someone pls confirm that what it does is that if your OS is windows7 then what happens is that all virtual OS you add are actually processed and executed by NTFS Windows7?
Reason I ask is b/c linux needs ext2/3/4 to work not NTFS so how can that happen?
I'm running Daemon Tools Lite, and have a conceptual problem. If I create a virtual disk, and then mount an .iso image of an OS on it, and then click on setup.exe to install the virtual OS, Windows 7 triggers a UAC warning.I don't understand why anything happening on the virtual disk would be subject to the host Windows 7's settings. It makes me fear that I'm not actually virtual, though the drive path certainly looked virtual.
I have 3 Virtual Machines on my 2TB drive, but it's close to full already and most of them are right at the end of the disk, where the drive is slowest. This doesn't make for an overly enjoyable experience when in use so, if possible, I'd like to move the VMs to the start of the drive in an effort to speed them up somewhat.I've got Auslogics Disk Defrag Professional, which allows for system files to be moved to the start of the drive, but I can't see an option for moving files of my choosing.Getting another drive and copying files across isn't an option either, as I don't have one to hand.
i was wondering if it is possible to boot my computer from a vhd and add it to the boot menu. I do not want to dual boot, I am trying to use the vhd like a dual boot. I am running Windows 7 Ultimate x64.
I installed MagicDisk awhile back because I was trying to mount a copy of memtest. Anyways, I ended up uninstalling MagicDisk, but the virtual cd-rom drive it created stayed behind.However, every time my computer either boots or even wakes up from sleep mode, windows automatically reinstalls the drivers and re-enables the virtual cd-rom drive. where to find the registry files I have to delete to tell my windows installation that I don't want that drive anymore?
I downloaded Oracle's VirtualBox because I wanted to test it out, but it created a 25GB virtual hard disk that I want to remove.Since I am using an SSD I have limited space (120 GB) and during the virtualbox setup I pressed cancel on the "create virtual disk" but it went ahead and did it anyways.I uninstalled virtualbox since, but the hard disk didnt remove itself along with the unistillation.
I recently had much trouble with my computer and was reinstalling OS many times! XP and windows 7. When I was installing windows 7 there were 3 virtual drives one about 400 mb named windows reserved and 2 others each (300gb) the 3d one was backup. I formatted first 2 deleted partitions, made 1 partition formatted again and then installed windows. The 3d virtual hard drive backup disappeared with all my stuff. Now I just have Local disc C: which is 300 gb and nothing else. So I am missing 300gb virtual hard drive with my stuff, where did it go?

I have 4 physical hard drives, 2 of them are 150GB and 2 of them are 1000GB. Both are mirrored at the pre O/S level in order to provide redundancy. On the 150GB mirror I installed the host operating system (Win Server 2008 R2 with Hyper-V) and the 1000GB mirror is just a Data drive. I've created my Virtual server in Hyper-V and allocated it 500GB from the 1000GB mirror. When I start up the virtual Server in order to install the o/s I will be asked whether to partition this "Virtual hard drive" i.e., have a C: drive for the virtual o/s and a d: drive for the virtual data. Of course they would be on the same physical disk anyway so should I bother partitioning the Virtual 500GB drive.
My Windows 7 Pro x64 has twice had to be completely reinstalled after serious faults.Each time before the crash Virtual XP had been installed and had created its own VHD.Both VHDs have been preserved, but the Virtual machine(s) have apparently isappeared. On each Windows 7 reinstallation, the important folders from the previous version were saved in a Windows.Old folder. I now want to reinstall VirtualXP and choose one of the old VHDs rather than create yet another one. What is the easiest and fastest way to do that?
So I can't change the drive letter. Do I need to use Partition Magic again? The more I keep hearing/reading "do you have a backup?" - makes me believe the tool (OS) isn't capable of handling/accessing the data properly.
