I have this laptop for work use. Due my work, I need to boot on Linux from time to time, and I use a Live USB with it. In order to be able to boot with that Linux Live USB i followed the following steps:
1.- Press Shift and Reboot
2.- Select Troubleshooot>advanced options>UEFI Firmware Settings and reboot
3.- On security tab > disable securite boot
4.- On Startup tab > UEFI/Legacy Boot --> select Legacy only
After doing that I was able to boot with my Linux Live USB and work normally, but when I shutdown the laptop, remove the usb, boot the laptop again and set back to defaults on the BIOS, the laptop wont boot up.
I re-enable the secure boot on security tab, and selected UEFI on the UEFI/Legacy boot on startup tab, but the laptop is not booting.
Solved! Go to Solution.

I´ve finally fixed the issue.
As I said before, sefting the Bios to default (F9) was not leting me boot back from windows. Extrangely after setting the bios back to default and saving, the laptop just went back to the boot process and got stuck unable to boot. When I checked the BIOS in the security tab>secure boot was disabled, and also the UEFI/Legacy Boot on the startup tab was again on Legacy (even though I set it back to UEFI)!!
The solution was: On another compluter create a bootable Windows 10 USB, boot the laptop with it, then reboot it and set the BIOS as follows:
security tab>Secure boot --> ENABLED
startup>UEFI/Legacy Boot --> UEFI Only
restart>Load Setup Defaults -- OS Optimized Defaults (DISABLED)
save, restart and remove bootable Win 10 USB
After doing that, the system booted up on windows. Then I rebooted again, pressed enter to go to the menu, pressed the key to go to the BIOS and in restart>Load Setup Defaults -- OS Optimized Defaults (ENABLED) enabled again the OS Optimized defaults.
I hope it helps others in the same situation.
