I'm new to Linux. I recently installed Ubuntu 16.04.3 on my ASUS Zenbook UX303LN laptop that had previously installed Windows 10.
I used Ubuntu normally for a few days but then when I turned on the laptop Windows 10 started automatically. I rebooted the laptop and this time it automatically enters the BIOS, where the boot priorities are missing.


enter image description here


I tried reinstalling Ubuntu from USB, but in the install options all the partitions disappeared.


enter image description here



After a couple of days of not using the laptop I turned it on again and GRUB started automatically and I was able to enter Ubuntu again. But after restarting it once again it automatically enters the BIOS and in boot priorities no option appears.
I tried using GParted to see if the partitions were there but only shows USB drive.


enter image description here



I tried using Boot Repair live USB but no boot repair option is available.
I also tried using Testdisk to see if the problem was the partition table as I read in another post but once again it just shows the USB drive.
Now every time I start the laptop it enters the BIOS automatically, where the boot priorities are missing.
I hope I was clear with the explanation, sorry for my English. This problem is driving me crazy.
Thank you very much.

  • Have you tried pressing F8 or F12 while booting ?

  • Often Windows updates which you may not have even seen. Make sure fast start up in Windows is off. And that drives are still set for AHCI in UEFI. Even if you turned fast start off before Windows turns it on with updates. askubuntu.com/questions/843153/… And Windows updates may have made it first in UEFI boot order.

  • I tried pressing F8 or F12 while booting but nothing happens. Everytime I turn on my laptop it automatically shows up the BIOS screen without boot priorities so I can't access to Windows to turn fast start up in Windows off.
