My New Windows 7 Setup booting from VHD (part 2)

Because I am running from the one and only installation on my machine, and I want to run the sequencer installation from a differencing vhd, Reboot with the DVD to get to diskpart so I can create differencing vhd files against a VHD that is not used.

Start the diskpart application like i described in my previous post.

Create differencing disks; create  vdisk file=“d:vhdseq.vhd”  parent=d:vhdwin7.vhd

Exit diskpart, copy the current GUID entry to a new one:  bcdedit /copy {GUID} /d “description between quotes”

Edit the device and osdevice registration of that GUID entry.

BCDedit /set {NEWGUID} device file=d:vhdseq.vhd

BCDedit /set {NEWGUID} osdevice file=d:vhdseq.vhd

There are a lot of posts on the internet about this differencing disk setup, that tell you to use the option vhd= in place of file=, for me this did not work. it seems that for me the option is file=. (an example I like about it and something that helped me here is this discussion…)

Until now everything seems to work, i got to choose the newly created option in my boot menu, and it starts up and I get to log on.

The next step will be installing the sequencer for App-V.
