I would expect you to get the same result there as well - just looking for a reproducable test case.

Great hearing that console clears it, maybe this is something that should be handled by iPXE boot part, or wimboot

@NiKiZe
My previous post only contained a part of my iPXE menu. The full menu that can hopefully be used to reproduce the display bug is contained below.

I should also mention for those that do not want to trawl through the lengthy thread on reboot.pro that this display bug was encountered with a Client system booting in UEFI mode with CSM disabled.

Stage 1 (menu item iscsia) booted fine and the display bug was not encountered. Stage 1 (SANHOOK the iSCSI Target and boot WinPE) was used to install Windows - using Windows setup.exe. After setup completed an automatic reboot occured.

The bug occurred when booting Stage 2 (menu item iscsib), executed after the Stage 1 reboot. Interestingly during one of my tests (after adding a displaybootmenu yes entry to the BCD store) a boot menu was correctly displayed followed by a Windows background image for a few seconds, then the console bug was encountered and I was not able to read the display.

Hope this makes sense.
