ipxe on Hyper-v (gen 1) : boot failure - groux-ml - 2017-09-11 15:49
i use ipxe and previously gpxe for intall many environmement.
actually since fex month i have a proble to intall on hyper-v new windows server VM. it work well on bare metal and also on KVM.
the problem is error 0x00005c, this is a HAL issue.
i need to use the last (or not so old) boot.wim image from a windows ADK/Windows server iso file.
the setup is
Windows server (2012R2 or 2016)
Hyper-v
ipxe iso file (with embeded script)
http server (apache)
BCD
boot.wim
wimboot
wimboot (up to date)
the embeded script is minimal
=====================
dhcp
set winboot-url http://....
set wimboot boot.wim
kernel ${winboot-url}/wimboot pause
initrd ${winboot-url}/bootmgr bootmgr
initrd ${winboot-url}/boot/bcd BCD
initrd ${winboot-url}/boot/boot.sdi boot.sdi
initrd -n boot.wim ${winboot-url}/${wimboot} boot.wim
boot
=====================
the problem is only with hyper-v, so it can be a bug in wimboot.
if i use a old boot.wim (from Windows AIK and not ADK) it s ok, but i need to use the last boot.wim and dism.

I see you already found a different thread,
start with removing "bootmgr" from your script - it should be extracted automatically from boot.wim
Test with setting only 1 CPU for the virtual machine - if that works you can check how to do that via the BCD, see thread here on the forum about similar issue with ESX hypervisor.

Thanks, but i have thesame problem
with or without bootmrg
and i have only 1 CPU for the VM ans i try with 1G of Memory to 64Go (1->2->4->8->16->32 and 64)
and same issue with 2 or 4 vCPU
yes i found another thread, but no answer in it except for downgrade the version of winpe and for my case it s not a solution.
