Driver issue on diskless windows installations

[toyebox]

Hey there and thank you in advance for any assistance.

I have been trying to install any version of Windows to an iSCSI drive. I understand windows 10 currently does not work, so I tried windows 7. The workstation I did this on was a Lenovo s30 which uses the driver: e1i63x64.sys file from what I can tell. The problem I'm having is, when doing the boot after the install, I get an error saying the certificate for that .sys file could not be verified. I press enter, hit F8, select disable driver verification, and then it comes up with an error about the same file saying it's missing or corrupt. I have tried numerous different windows 7 iso's. I was successful at installing Windows 7 in a VM via the same method though(I'm assuming it's not using that driver).

My question is, has anyone else encountered this? Is there any recommendations to get past this part? Thank you!
