hello everybody,

before you come to write this post I checked the official documentation of
centos. to be brief:

- I format my usb pendrive in fat
- Using the command dd if =name.iso of =/dev/sdx (with or without bs for
the purposes of issue, and 'indifferent)

Restart the system and remains in the screen with the cursor flashing
I also tried with other distributions and every time I get the same result
side bios and there 'no setting for secure boot or similar

can you give me a hand please?
thanks in advance

best regards
