I had to make a correction. I meant to say pre-1Gbit internet not 10Gbit internet. We have 10G backbones (intranet) but not to the internet.

@pauleb Intriguing. So you didn’t need to create a EFI entry for the drive? I wonder if it was already there for that drive from the previous image or something.

I guess mine did not work because I first imaged my test machine with an MBR image, which made the EFI entry no longer show up.

Good luck, and thanks for the info.
