@briancurry said in PXE Boot Errors:
Now the endpoint boots to what looks like the FOG imaging menu but then goes away after about 2 seconds.
Can you take a picture of this? Not sure if I follow what you say here. Don’t think I’ve seen this before that the menu goes away after 2 seconds, usually it’s 8 or so by default.
@phishphan said in Issue Imaging HP EliteDesk 800 G3:
I currently have the partition set to Singe Disk - Resizeable but I’ve also tried Multiple Part Single Not Resizeable without any success.
When switching to non-resize, did you re-capture the image from your master machine? You need to!
Your partition layout is preventing FOG from being able to properly resize as the third partitions seems to be the recovery part which we don’t want to move as it could break recovery.
Are you saying that you deploy the image to the very same machine or is it another one from the same model? Compared all BIOS settings? Same BIOS firmware version?
@cjp82placer Possibly some kind of reverse SSL proxy within your network that is intercepting and maybe filtering all HTTPS connections?
@george1421 I am really keen to hear what you did with kernel -300m as this seems to make a difference… right track I suppose. Maybe this is some kind of timeout?!
@rayco said in Customized image of Windows10 1803 RS4, partition resize issue:
I’m traying diferents methods but with unlucky results.
What exactly have you tried and which errors occurred? We can’t help without knowing more details from you.
@george1421 Found this in the diff… no idea if that could be related:

@cjp82placer Are you sure your internet connection is working fine? I can git pull/clone without an issue.
nvme nvme0: failed to set APST feature (-19)
That -19 is usually means “No such device” (reference). Very strange.
In that arch linux bug report there are CONFIG_PCIEASPM_... kernel configs mentioned. Had a look at those yet? @george1421
What I was just thinking: Maybe Fedora has some special NVME patch included in their kernel that we don’t know about yet. Has anyone ever looked into the full Fedora kernel patchset?
EDIT: Not sure but that might be the one: https://git.kernel.org/pub/scm/linux/kernel/git/jwboyer/fedora.git/snapshot/fedora-kernel-4.13.9-300.fc27.tar.gz
EDIT2: Ok, sorry. This seems to be the full fedora kernel code. Anyone keen to create a diff to a vanilla kernel with that?
@briancurry Just guessing here but to me it looks like you are using an external DHCP server, provided by your network admins?! Just looks like to me from the IPs seen on the screen. So I am wondering who did set up the DHCP server to PXE boot clients? Are DHCP options 66 and 67 set correctly? Possibly there is a typo in the filename (option 67), maybe just a leading or tailing space character?!
@phishphan Allow me a couple more questions:
Please post the contents of d1.fixed_size_partitions, d1.minimum.partitions and d1.partitions which you find in the image directory on your FOG server (usually /images/…).
