Thank you very much again. Your help is very much appreciated.
I did look at the post but I assume my lack of technical understanding is the culprit, please excuse me.
I followed your instructions but its missing the USB boot portion. Would you mind sharing how to appropriately usb-boot the vm?
I tried adding a USB Device via pass-through (both via port and device id) which then enabled me to boot and create the image. However at the end of that process I am still presented with the corruption error. So I assume adding a USB device like I do is the issue and I am trying to work out how to boot from the image that gets downloaded at the beginning of your instructions.
Thanks again!
