Windows 2008 R2 Session -- 20.10.2009

Resources and scripts from presentation.

PowerPoint presentation.

Question from today:

Is it possible to have Windows XP boot from VHD.

The answer is no (well, at least it is not supportable). This is only supported on Windows 7 and Windows 2008 R2

More information on this can be found here.

Could you explain in a sentence or two why DFS is not a HA solution and such a configuration is not recommended. What problems does it usually have (is the replication not configured properly...).

Native boot for other OS's (not supported of course):

@Nejc,

You can use these:

bcdedit /copy {current} /d "Windows 7 VHD"

This will give you new GUID and description in boot menu.

Replace GUID below with the one you got in the first step.

bcdedit /set {6ba352e7-bc85-11de-b768-ea21ab1e54fa} device vhd=[C:]\Virtual_Computers\Windows_7_Ultimate.vhd

bcdedit /set {6ba352e7-bc85-11de-b768-ea21ab1e54fa} osdevice vhd=[C:]\Virtual_Computers\Windows_7_Ultimate.vhd

bcdedit /set {6ba352e7-bc85-11de-b768-ea21ab1e54fa} detecthal on

When you want to clean up you can use

bcdedit /delete {6ba352e7-bc85-11de-b768-ea21ab1e54fa} /cleanup
