When installing Fedora() after Windows, Fedora won't boot at all, how to solve?

Question

linux

Good morning, help me figure out how to install two OSes but a new computer. (system on x570)
There are two disks one ssd and one hdd. I want Windu on hdd, Fedora(30) on sdd.
Prior to this, there was no experience of installing two operating systems, only separately.
Following this guide, everything seems to be not difficult -

but in fact it is not possible to boot a live version of Fedora from a USB flash drive.
So what did I do
Put Windu on hdd.
I downloaded Fedora and uploaded it to a USB flash drive using their standard program.
In the BIOS, I chose a bootable flash drive in UEFI mode (I already tried it in different ways, to no avail)
The Fedora bootloader appears, I select 1 item, (Start Fedora-Workstation-Live 30)
After that I catch it

I will be glad to any advice! Thank you!

Answer 1

The key clue will be information about the first error. I suspect not all files or the system is looking for them in the wrong place.
SHIFP+PGUP to scroll - most likely will work.
The option is to try downloading an older image or from another mirror.
RUFUS might be better off writing to a flash drive
