Hi ,
I tried to install clean Win 10 on m ROG , but to do , I needed to change from fast boot and to disable secure boot.
Then allowing CMS option , and i could install.
After I installed the OS , everything is ok , But i would like get back to the fast boot option.

If i am setting fastboot back up , I can't access the OS, every boot goes sirectlly to the bios in a loop.


How can I fix it , to get back the fastboot option.

Yes you will need to turn enable fast boot and Secure boot disallow CMS. Set up your USB Install media to boot UEFI and then install In UEFI Mode. You may have to clean you disk and convert to GPT. You can do this at the beginning of install after you put in language hit the Ctl and F10 that should bring up a command prompt use disk part to do the conversion after complete the install will finish.
What you did by turning off secure boot and enabling CSM was set you system up to run Legacy mode BIOS MBR.
When booting your install media hit the esc key that should bring up a boot menu select the UEFI USB or UEFI DVD which ever you are using.
Here are several tutorial on how to do this.
