I was not able to boot in bios mode on Windows 10 hyper-v. I found out that vm higher than 8.0 had issues. I made a new vm on windows server 2016 in version 8.0 and this is working well. Maybe is this your problem?

@Andrew-Seals If you know the mac address of that win10 hyper-v server key in this url into the browser and lets see what it gives us:
http://<fog_server_ip>/fog/service/ipxe/boot.php?mac=<mac_address_of_vm>
Hint: Replace the bracketed text with the real info for your site

That will spit out a bunch of text, please post that text here in a code block. That this the program behind the iPXE boot menu. I want to see what the default exit is set to.

@Andrew-Seals It looks like your bios exit mode is “exit” not sanboot.

Here is your exit mode:

choose --default fog.local --timeout 5000 target && goto ${target}
:fog.local
exit || goto MENU

If you look at my exit mode:

choose --default fog.local --timeout 5000 target && goto ${target}
:fog.local
cpuid --ext 29 && set boot-kernel refind.efi || set boot-kernel refind32.efi
imgfetch ${boot-url}/service/ipxe/refind.conf
chain -ar ${boot-url}/service/ipxe/${boot-kernel} || goto MENU

Edit
I was testing something on my dev server here is the correct exit mode for bios (SANBOOT). I had everything exiting to refind.

choose --default fog.local --timeout 5000 target && goto ${target}
:fog.local
sanboot --no-describe --drive 0x80 || goto MENU

@george1421 I went into Fog System Settings -> Fog Boot Settings and changed it to SAN Boot. Now the machine is sitting at: “Booting from SAN device 0x80”

george1421 · Jan 18, 2019, 4:03 PM

@Andrew-Seals Well that’s strange. It works correctly on FOG 1.4.4? What do you get when you key in the same url to your 1.4.4 environment. It would be interesting to know what exit mode you have there. http://<fog_server_ip>/fog/service/ipxe/boot.php?mac=<mac_address_of_vm>

Andrew Seals · Jan 18, 2019, 4:04 PM

@george1421 Changed it to GRUB_FIRST_HDD. It is now working on the Hyper V virtual. Let me see what it does on the other physical machine that was giving me issues.

george1421 · Jan 18, 2019, 4:05 PM

@Andrew-Seals Sanboot should work by default, you may have to use grub for hyper-v but almost always sanboot works and should be default for bios. For uefi exit it should be rEFInd.

Andrew Seals · Jan 18, 2019, 4:37 PM

@george1421 I changed EFI to rEFInd. I changed legacy to the GRUB_FIRST_HDD. So far every machine I have found is working! Thanks for the help. My Bootfile Name on the DHCP server is set to: undionly.kkpxe. I have seen others who use undionly.kpxe. Should I just leave it since it is working?

george1421 · Jan 18, 2019, 4:41 PM

@Andrew-Seals The standards for the ipxe boot loaders are:
BIOS: undionly.kpxe (kkpxe only if you have problems with kpxe.
UEFI: ipxe.efi (or sndonly.efi if you have problems iwht ipxe.efi)

If your environment has to support both uefi and bios systems and you have a Windows 2012 or newer dhcp server or a linux dhcp server you can setup dynamic boot file assignment by following here: https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence
