hello ,
this is a useful Cd to have for repairing boot problem and restore in windows 7
http://neosmart.net/blog/2009/windows-7-system-repair-discs/

note it also contains the new Microsoft tool called DISM
deployment image servicing manager
it can mount image wim and also insert drivers into image etc

Deployment image servicing and management (DISM)
new deployment tool in windows 7
to do tings with the image you got to mount it first and work with it OFFLINE

to mount the image use this command
DISM /mount-wim /wimfile:c:\dismdemo\imstallationCaptured.wim /index 1 /mountdir:c:offline

after image is mounted we can see the pakages in the image.

DISM /image:C:offline /get-packages

also can see features in the image

DISM /image:C:\offline /get-features

we now can see all the features in the image and wether they are enabled or disabled ?

new to DISM is the ability to add and remove drivers

DISM /image:C:\offline /add-driver /driver:C:\dismdemo\driverpackages\decon\toaster

to see the drivers
DISM /image:C:\offline /get-drivers

original name is kept but name in the image is changed to say oem65.inf to avoid naming conflicts.
original file name is toastco.inf

to remove this driver from the image

DISM /image:C:offline /remove-driver /driver:oem65.if

to check if it was removed again use
DISM /image:C:\offline /get-drivers

:)
