Thanks!
I was successfull on another computer. It required setting Hard drive BBS priorities in BIOS (i just set flash drive as first device).
However im still unable to boot on target computer.
Both computers are 64-bit and have UEFI boot as option in BIOS menu (disabled in both cases).
Target computer have debian stretch installed as the only operating system, so it just prompts me to GRUB and then loads debian.
After trying different boot configurations in BIOS i checked if it still boots from flash drive with standart debian iso (it does).

Does this computer has UEFI? Or is it more an old PC? Some BIOS have
different options how to boot from USB stick. There's SUB floppy, USB
hd and some other options which type of USB stick a BIOS can
boot. Maybe try the USB stick on another computer to see if it's
working correctly.
