I just found this thread whilst searching for the “Stuck on EFI Stub” error which I also have on a Lenovo V130-151KB Laptop.
I changed our dhcp boot option 67 to point at the ncm–ecm–axge.efi file.
This resulted in my being able to re-image a laptop with a broken LAN port via a Dell USB Lan adapter.
I hope this might be of use to fellow victims of Lenovo.

I have managed to get the USB LAN to boot at last!
I ended up using the ncm–ecm–axge.efi boot file and it stopped stalling.
Thanks for all your help, i will look into the USB boot as I am sure it will be useful in future situations.
Might be worth including it on the following page?

It’s certainly worth a try. I don’t see why it wouldn’t as it will let me boot from the USB LAN adapter.
Do we have some instructions on creating a bootable USB for fog? It sounds useful for other projects, too.
I have managed to image an identical PC to this previously using IPXE and the same USB adapter. I just can’t remember what i did to get it to work! I do remember it took me ages and celebrating like i’d won the world cup at the time. I thought i’d written down what i did, but i’m unable to find the notes i made.
Thanks for your reply.
I should have mentioned that the cloudbook is an intel based windows laptop. I think their “cloudbook” definition basically means “Low spec, not much storage”
I can’t find any bios settings about mac passthrough on the laptop itself.
I have noticed if i disable the IMI flag in the fog settings for the USB adapter, the laptop stalls at 0% on bzImage before getting to the fog menu. When i re-enable the flag, it will boot back into the menu.
Do i need to try some updated ipxe/efi boot files from somewhere?
Hi,
I’m currently hitting my head against a brick wall with regards to a FOG imaging issue.
We are currently using 1.5.9 RC1, i think.
I am trying to image a cloudbook (Stonebook Cloud C10A) via a USB network adapter (Startech USB310000SPTB). The cloudbook doesn’t have a wired ethernet connection.
I have managed to get this working at some point in the past, but for the life of me can’t work out how. I have the USB adapter set up as an intermediary where i register the host’s wifi adapter manually in fog and use the USB adapter as a dummy host to do the imaging.
The laptop will boot as far as the FOG menu (most of the time, see later). (Screenshot 1).
However, the USB Dummy Host is not being detected within the menu and the menu says it is an unregistered host.
That would be ok, but when I try to image or run debug mode from there, the process gets stuck on downloading the bzImage file at 0%.
Occasionally, the machine will hang on downloading the relevant files to boot into fog at all, and refind has also been inconsistent when loading in order to boot from the built in ssd.
I have also experienced this downloading issue with another PC which i managed to resolve by using the Legacy PXE boot option. I do not have that option with this cloudbook.
The cloudbook is EFI booting, and we have nearly 1000 other PCs imaged using FOG that work pretty reliably for the most part.
Hopefully someone with much more knowledge of how this works than me can give me some pointers. I am quite familiar with fog having learnt through trial and error over many years, but haven’t quite got my head around the sequence of events in the background.
Thanks!
