Problem solved and it was silly. Even IF I set USB hard drive as first boot device in boot order (in both UEFI and legacy boot orders listg) laptop is not booting from USB.

 

I just had to press F9 to get boot menu and then choose USB. I installed win10 in Legacy/MBR mode without any issues.

 

Thanks all!

Good job!

The boot order should work if you have all settings and formats right and are creating a bootable USB from a bootable image.

 

When you have the BIOS settings so that USB Boot is enabled and Legacy Support enabled and the Bootable USB partitioned in MBR style. FAT32 is the safest format to work.

 

To make the order work in UEFI, you need to enable USB boot and disable Legacy support and probably also disable secure boot. The USB needs to be using the GPT partitioning scheme and have the correct loader etc. in the EFI partition.

People are using their precious remaining lifetime to try and help, so it is common courtesy to come back and tell what the solution eventually was even if you found it elsewhere. It is for the benefit of everyone.
