Why won't it boot from a flash drive?

Good morning. In general, it was necessary to install CentOS 7 on a computer with characteristics (core i5, 4gb ram, 500gb hdd, windows 7), I want to note that the hard drive is working, the ram too, the computer is almost new, it worked under win7 for some time.
Recorded a flash drive in different ways.
Windows - unetbootin, win32DiskImager, Rufus, dd.
With Linux - dd and for multisystem pampering, yumi
Tried both versions of Centos Everything and Minimal.
Also tried Arch linux and Ubuntu.
All these flash drives work on another computer.
But the working computer does not boot from the flash drive and issues a "popular" problem on the red hat forums:
ata8.00 exception Emask 0x52 SAct 0x0 SErr 0xffffffff action 0xe frozen
ata8: SError: { RecovData RecovComm UnrecovData Persist Proto HostInt PHYRdyChg PHYInt CommWake 10B8B Dispar BadCRC HandShk LinkSeq TrStaTrns UnrecFIS DevExch } ata7.00
: failed command: IDENTIFY PACKET DEVICE There is no UEFI/Legacy mode selection in the BIOS. There is only the inclusion of Legacy usb support (which is included). Flash drives are defined as [UEFI: JetFlashTranscend 8gb 8.07] That is, a separate option. It looks like this: 1st boot - Removable device 2st boot - Hard disk: hitachi ... 3st boot - UEFI: JetFlashTranscend... Thus, the flash drive does not boot into legacy mode, since it is written to \ for uefi.
The system, as expected, simply loads the OS from the hard disk, skipping the Removable device.
If you swap options 1 and 3, the error described above appears.
I don’t know where to dig, obviously the problem is in the BIOS, I suppose. What are the options for installing some system on this computer?
At the moment, I just have to find a blank and try to install it the old fashioned way.

1. It can be assumed that you (in UEFI) have Secure Boot installed.
2. Each manufacturer has its own hot key to force boot device selection, see bootable Linux on a USB flash drive
