I've an uefi machine!

[bour59]

hello,
newbie with an uefi machine!
on non uefi machine
-all my os boots from grub2 menu
...../sda1 slackware-current (grub2 installed)
...../sda2 some porteus on ext4
........../v4.0/boot and /porteus
........../v5.0/boot and /porteus
...../sda3/slax and other linux
menuentry in /mnt/sda1/etc/grub.d/40-custom

on uefi machine with secure boot disable
...../sda3 windows 10 (grub2win installed)
...../sda4 slackware-current (elilo installed)
...../sda5 some porteus on ext4
........../v4.0/boot and /porteus
........../v5.0/boot and /porteus
I use grub2win to boot windows
and elilo to boot slackware-current
I boot porteus installed on usb disks
I presume I've to add menuentry in grub2win
to boot the porteus on sda5
q1/ same menuentry as for non uefi grub2?
q2/ in what directory of windows?
q3/ any good doc about grub2win?
thanks for any help

Grub2Win generates the menu for booting Windows.

with grub2win the customer menuentry are in a file on the windows disk :
c:/grub2/userfiles/usersection.cfg
