Virtual hard disks ( VHDs ) on Windows 7
Posted on September 3rd, 2010 in battery review, battery specs, digital camera battery, knowledge, laptop battery | No Comments »
Virtual disks in the VHD format played so far only for Microsoft ’s virtualization software a role. For Windows 7, virtual hard disks to an important component for backups , XP -Mode , boot manager and disk management. The Home versions of Windows 7 after all a subset of control in dealing with VHD images.
The VHD format (Virtual Hard Disks Virtual Disks = ) is used for a long time as an image format for Microsoft ’s virtualization software, Virtual PC. This task will continue to meet under Windows 7 Thus uses some of the XP -Mode a 3 GB VHD with a Windows XP SP3. The rechargeable in Windows 7 Professional , Enterprise and Ultimate is a full virtualization , integrated virtualization software that can , other than the default VHD to create and use with XP.
For Windows 7, the VHD format is supported but by far the virtualization system .
VHD for system image:
Virtual disks in the VHD format created Creating Windows 7 also in the full backup of the system ( ‘ system image ‘). That was already running Windows Vista with ‘Complete PC Backup ‘of the case, but it was with Windows on board means possible , to commit these fuse completely. A shop (Mount ) of the VHD, as to extract some specific data, there is not possible. This requires the installation of the software Virtual PC and Dell latitude d820 battery . For Windows 7, the VHD support is built into the system.
Create virtual hard drives and load:
Disk Management in Windows 7 features in the menu ‘ Action ‘ , the new points’ virtual disk ‘Create and append ‘ virtual disk ‘. Attaching means downloading an existing VHD and selecting the virtual hard disk is done in seconds: The content of the VHD is loaded as a new drive appears in Explorer. Creating a new VHD Disk Management is only useful for pure data containers – a bootable or usable VHD as a virtual system is created only through the virtualization software and Dell gd761.
The loading and unloading of virtual disks in the VHD format can also provide an alternative fully informed of the Kommanozeilen Diskpart.exe tool . The program was expanded accordingly. For example, the command
select vdisk file = ‘\ \ server \ share \ backup.vhd ‘
attach vdisk
binds to a VHD on a network server in the system. An appropriate select / command followed by ‘ Detach ‘ is the virtual hard disk again. Using Diskpart to deal with VHD images is completely scriptbar .
Virtual boot disk:
VHD images, which were of virtualization in Windows 7 integrable and contain a complete operating system , are also bootable under Windows 7 (which is an important caveat : Do not be created with Virtual PC 2007 VHDs bootable !) .
It then suffices to register the corresponding VHD file to the boot manager. The deterrent , but here indispensable BCD Editor Bcdedit.exe the user makes this simple task in itself as difficult as possible :
bcdedit / copy {current } / d ‘Boot VHD ‘
bcdedit / set { … } osdevice vhd = [ C:] \ path \ Datei.vhd
bcdedit / set { … } device vhd = [ C:] \ path \ Datei.vhd
bcdedit / set { … } on detecthal
In the curly brackets { … } is exactly three times that 36- digit identifier ID register that returns the Copy command from the first command.
The example shows how the VHD virtual hard drive is integrated into the boot manager. If the VHD then loaded at startup in the middle should break off , the computer must also be prepared by the Sysprep.exe to hardware independence. Sysprep Windows 7 is included by default at% windir % \ System32 \ Sysprep – simply Sysprep.exe , ‘ select out- of- Box Experience ‘and also activate the option ‘ generalizing ‘.
VHD support in Windows versions:
The Home versions of Windows 7 virtual hard drives support only in part. The boats will VHDs Professional, Enterprise and Ultimate reserved . The same applies for the integrated virtualization (XP mode). The loading and unloading of VHD images using Disk Manager and Diskpart works! but also in the home versions.
