ERD is created from Windows 7 ISO, which means if you want ERD from Windows 7 SP1, simply point the ERD Creating Utility to a Windows 7 SP1 ISO.
Erm actually I have the ERD65 software from MSDNAA. It is a software use to create recovery ISO. It is not a bootable ISO by itself. It is just a program like Windows 7 USB Tool. So to create the Recovery Bootable ISO you need to point it to a Windows 7 ISO image. Step1: Install ERD65 to a working computing Step2: Point it to a Windows 7 ISO image Step3: Point it to any other Recovery Programs (Besides the standard Windows Troubleshooting Tools) you want to put it + Windows 7 debugging Symbols Step4: Get the Anti-Malware Updates if you want Step5: Generate the Recovery ISO Step6: Use the Windows 7 USB Tool to point it to the created ISO(smaller in size than a standard Windows 7 Installation ISO) Step7: Boot it from the problematic computer. So to get the SP1 verson just sub the Windows 7 ISO with the Windows 7 SP1 ISO ( Although IMO it is pointless) Do I have to post screenshots to convince you?
