Hello experts. my device is Acer Aspire F5-573G-7777, with Intel Core i7 7th Gen CPU & NVIDIA GeForce 940MX GPU Processors.i recently switched my OS from Windows to Manjaro-x64-KDE-5.26.5
the installation Manjaro was done without problems and after Restart Laptop, the Device Boot Manager did not recognize any Bootable Disk, While i had set the BIOS Setting on UEFI & Secure Boot off. however on the Live USB, Manjaro that was installed on the “Sumsung EVO 970 SSD” was recognized and run…
Please help me to solve this issue. i am not familiar with Linux Kernel

I suspect you have one of the Insyde EFI/bios that at least some acers use. In those ‘bios’, if you have one, you need to set a supervisor password, then enter the bios in admin mode. Somewhere (by memory it is under Security, ) there is a section that was grayed out before you went in with the supervisor password to “Select an UEFI file as trusted”. That is where you can find your boot file for your linux install and add it to the choices under Boot.

I’m so grateful for your help. It was a challenging time but you made it easier
so i entered to BIOS (InsydeH20 Setup Utility)

  1. enable Secure Boot option in boot tab
  2. in Security tab, i Erased All Secure Boot Settings, and save that
  3. in “select an UEFI file as trusted for executing” i trusted “manjaro/grubx64.efi” and saved
