Dear Sirs,

when I try to write a *.img file with win32 discimager v1 to usb, there is nothing on the usb drive except a "efi" directory with a sub "boot" directory which has 2 files: "bootx64.efi" and "startup.nsh". When I try to boot from that stick, boot process is starting but hangs after 1 minute.

Hardware: Jet Flash USB 3.1/3.0 16 GB
Lenovo W520 with uefi bios and usb uefi bios support enabled.

Apologies that nobody replied to this PR until now.

Windows does not have support for UFS filesystems so it's expected that you see only the ESP (EFI System Partition), which is FAT formatted and contains the bootloader components.

You say the boot process hangs after 1 minute -- what output do you see leading up to the hang?
