Fairly straightforward one I hope... I want to build an ISO from the latest 2K8 R2 VHD (7260). I know the process was incredibly simple for 7 7260 and successfully made a bootable install ISO from the 7260 VHD (converted to install.wim) and the 7100 x86 ISO.

However, the only prior 2K8 R2 ISO I have left is the beta build. Should I be able to use this as the loader for the 2K8 R2 7260 VHD once I convert it to install.wim? If not could I, for example, use the same Windows 7 7100 ISO to build a working install for Server 7260?

What for? There is working iso on Wzor.

It's for Windows 7 vhds but should still work for Server 2008 R2 VHDs.

They don't work for Server 2008 R2. You get an error basically telling you it can't find the image to install.

BA has this as a rebuilt ISO already, along with the VHD... so why bother rebuilding it again?
