I am trying to install Linux Debian 8.5 (dd'ed it successfully to USB stick) on SD card of Zenbook UX303UA. However, Grub is 1 version. I cannot boot from the USB and there exists no menu option for the fetaure in the ultrabook. I accessed the Bios by pressing esc at the login, since it does not start naturally by USB and does not give me a list boot options. I think the USB is at /dev/sdb1 now so one option is to configure Grub directly. Fig. 1 Bios and Boot, Fig. 2 Bios, USB configuration and Advanced
Iterating GAD3R's proposal
Disable successfully Fastboot in Bios Boot. Fig. 4 After pressing Esc at login when Fastboot disabled*,
Fig. (5-7) are about unsuccessfully setting up boot by USB
- first rename the option as USB or whatever, since just name (Fig. 5)
- it requires the location of the boot there (Fig. 6)
- I cannot find any other location than the current USB SSD (Fig. 7)
Fig. 5 Renaming as USB in Boot , Fig. 6 You cannot Enable Legacy Boot for some reason (Why?), Fig. 7-10 You cannot find right location for new boot option
I cannot find a way to boot from USB.
2nd Iteration
I disable Secure Boot in Security > Boot. I enable CSM. I press Esc at the login. I get the list of items to boot from.
- My test USB works
- My Debian installer does not work so this confirms it is faulty.
Problem solved!
Hardware: Asus Zenbook UX303UA
OS: Ubuntu 16.04 64 bit Linux kernel 4.7
Grub: version 1
