RemixOS 3.0: My adventures with secure boot

Hi,
i was dying to try RemixOS 3.0.
Running a Surface Pro 3 the mere thought of booting out of secure boot mode and imposing the bright orange screen to my eyes every time i started the thing was discouraging any attempts to installing RemixOs.
Using another machine i installed RemixOS on a flash drive and notied it used the ubuntu grub2, which is signed and doesn't require secure boot disabled in order to start, and to my surprise i could boot remixOS from the flash drive without disableing secure boot on my surface pro 3.
Then booting on a flash drive on a tablet with only one USB port... not good enough for me so if i could boot to USB with secure boot maybe i can do it from hard drive, to be honest my first attempt wasn't successful using a NTFS partition to install Remix, so i tried to install it to a FAT32 partition and was surprised when the OS actually booted in secure boot mode despite two errors :
  • secure boot forbid loading /efi/RemixOS/exfat64.mod
  • secure boot forbid loading /efi/RemixOS/ntfs64.mod
i don't know what are those modules used for, as of now the OS runs fine except for the fact that double clicking on desktop icons crashes and resets the OS but this behaviour happens on all the machines i tested (surface pro 3 and my desktop computer).
[EDIT] This only happens if the icon moves when double clicking probably comes from touchpad sensitivity and the way they handle rearranging the desktop [EDIT]
TL;DR:
  • Found out i could boot RemixOS with secure boot ON from a USB flash drive.
  • Tried to do the same from hard drive.
  • Didn't work using NTFS.
  • Worked using FAT32 despite not being able to load exfat64.mod and ntfs64.mod
Questions:
  • Did someone actually found a way to install and run RemixOS without errors in a Secure Boot environment ?
  • What are exfat64.mod and ntfs64.mod used for ?

PS : touch and multitouch works fine here (i've seen people complaining about it not working, maybe for an older version)
