My motherboard recently died on my windows 7 machine which meant after replacing the mobo I was getting a digital signature error on booting up. I would work around this by using the F8 shortcut to go into the advanced boot options and disable driver signature enforcement.
I decided to upgrade to windows 10, and installed this onto a different harddrive on the machine (to make sure all my programs would work smoothly on the new OS).
Now when the machine boots up and I get the two OS options (Windows 10 and Windows 7). If I try to boot up in Windows 7 I am no longer getting the advanced boot menu options up no matter how much I’ve tried using the F8 shortcut (I’ve tried pressing it at various speeds and various points of the boot up probably 30 times now), which means I’m unable to boot up in Windows 7.
In the below link are images of the three stages:
- OS boot options page
- 1st Windows error recovery page (“Windows failed to start…”)
- 2nd Windows error recovery page (“Windows cannot verify the digital signature…”)

Any guidance on how to boot Windows 7 disabling the digital signature / getting the advanced boot options page up would be greatly appreciated.
