You'll have to manually add the coding to the end of the line. I do not know it at the moment. It is in other posts in this group, and on G+.
1) DISABLE SECURE MODE,
2) Change BOOT MODE from UEFI to LEGACY,
3) Try to find under your computer BIOS an option where you can disable "DISCRETE GRAPHIC ADAPTER".
After the installation on USB stick, you can ENABLE UEFI. The other 2 options have to be disabled if yo want to use RemixOS.
That worked for me.
when you have the choice of Resident and Guest Mode, hover on Resident Mode and press tab then type exactly this: (INSTALL 0)
Many thanks
