Why is my computer ignoring a bootable linux flash drive?

Question

USB

There is a bootable flash drive with linux mint cinnamon 18.2. Bios sees it. In the list of priority boot drives is in first place. I tried to juggle in different ways. I removed it from the SATA boot disks with my Windows, pulled out and inserted the USB flash drive, turned off the fast boot, dug all the settings in biose, went through the entire Internet. On the laptop that stands next to it - everything works, but on a stationary computer it does not. Windows just loads. By the way, when you turn on the motherboard menu, it says: F8 - Boot Menu. So, no matter how much you dolby in F8, the Boot Menu does not start.
What to do?

Answer 1

fast boot must be disabled when the computer is loaded faster than you have time to press the keys to enter the boot menu or the recovery menu.
Check the secure boot setting in the BIOS - if it is enabled, then only certain Windows operating systems, such as win10, can boot.
Then check in the BIOS which bootloader is used by MBR (legacy) or UEFI, or both at once.
It often happens that it is not possible to boot from a flash drive because the uefi bootloader is installed on the computer and the flash drive was created by mbr, and this moment was not taken into account when creating a bootable flash drive. In this case, the flash drive will not boot.
You can use the Rufus program to partition the disk and create a bootable USB flash drive and carefully look at the selection of fields.
