Boot Windows 7 from VHD - an amazing concept

120 posts in this topic

like all other features, the VHD boot is controlled by licensing.

It is only licensed to Ultimate and Enterprise, only those 2 version have the Kernel-NativeVHDBoot Policy enabled.

Would be nice to see a tool that can do all this... drag and drop your VHD to boot (or a boot menu manager), set a VHD virtual drive, etc...

I have a question: I received the windows 7 upgrade DVD I did a clean install (rather then installing it over my vista installation), but what I for got was my blue ray drives codac was p reinstalled on the vista installation. Now what I want to do is make an Image of my Win7 install create a .VHD and put the image on that and save it to a flash disk then I want to run the HP vista restore disk (so I get all my stuff back) then I want to mount the VHD so I can boot off of it.

Will it work (I have 64bit 7 Home Premium)

Home Premium can not boot out of VHD file.

Only Ultimate and Enterprise can boot out of VHD file.

all versions are technically able to boot from VHD, but MS only licensed Enterprise/Ultimate to use this feature. When you try to use other Edtions, the Software License service won't allow you to use this feature.

When you have a bootable Windows 7 VHD installed on a Vista or Sever 2008 R2 primary host partition, and boot the Windows 7 VHD system; can it 'see' the host file system (Vista or Sever 2008 R2) on the primary (NTFS on bare metal) partition?

There are contradictory comments about this on several forums and blogs; neither I can find no definitive statement in the Microsoft documentation regarding whether the booted VHD system can see the primary boot/host partition (assuming there's only one), though it is clear it can 'see' other volumes...

Going by my own personal experience with installing W7 to, and running it from, a VHD, I can confirm that it will see the host partition's filesystem. However, it will see the virtual filesystem as C:/, I believe, if I recall correctly (I haven't actually used it that much), and the host partition as some other drive letter.

So is this VHD boot method recommended only for testing or could/should I use it as a primary method of running Windows? I'm asking this because having Windows in a VHD file would make it very easy to do a fresh install. I would just need to install Windows once to a VHD and then make a backup copy. In my mind this sounds similar to Ghost images that you could directly boot into.

There are 2 features not available in VHD boot as far as I know: calculating the Windows Experience Index and hibernation. If these are important, than I recommend not.

Otherwise, it's all the same. Some people say there's a performance degradation but I've never seen that when beta testing.

missing hibernation is really a blocker why I don't use it for daily usage. My VHD installation is only used for VS2010 testings.

You can only boot Windows 7 Ultimate (or Enterprise) from a VHD.

If you have Windows XP you can install Windows 7 Ultimate into a VHD.

Whilst the installation of Windows 7 the boot manager of Windows 7 will be copied into the Windows XP partition. The installation will also build a boot menu where you have the choice to boot "Earlier Windows version" (means XP) and "Windows 7".

Being able to boot only win7 is useless,if it's able to boot other OSes,that would be more convenient for us :}

When this VHD boots, except for the Virtual Hard Drive.. does it run inside a VM or is the OS, all its processes and other stuff actually running without a VM?

booting from VHD is like normal native Windows 7/Server2008R2. The only different is, that the data are not stored on a partition. They are stored inside the VHD.

The OS data is not stored on a partition but is stored on a VHD.

Your other data can be stored anywhere, another partition or another drive.
