windows10 recovery boot : works on qemu, not on standard bios/UEFI

[jlmalet]

I created a usb bootable pen, with a linux (gentoo livedvd) and a recovery for windows10, I tested it on quemu, both works fine (at least display something graphically, windows complain about not enough memory but it booted) on regular bios, the linux live dvd boot fine but can't start the windows10 recovery... the display flicker, and go back to grub menu... can't figure what's wrong since no log is reachable... any idea?

I stumbled into a similar issue. qemu testing works fine but a real boot directly falls into a grub 2 loader. Windows 10 installer never works.
