In the bios, there were several bootable discs, and after formatting the SSD and removing the USB key, this list has not changed ...
And even with no hard drive connected, performed the Clear COMS, stack removed
I understood that this list is written in the BIOS, so I flashed, now everything is in order on this side.
3 identical clover boots and 2 MacOS X boots without any disc connected ...
And for the USB key, it's for saving the capture.
So I redid a clean install of Catalina 10.15.4, and the problem is still present (it blocks the installation after restarting) so I removed the graphics card and everything is installed correctly.
Once installed and updated, I put the graphics card and the screen still plugged into the iGPU of the CPU and the startup hangs at:
i0ConsoleUsers: gI0ScreenLockState 3, hs 0, bs 0, now 0, sm 0x0.
Parts list: i7 4770 (HD 4600 Graphics I don't want to use) I'm not for sure on the motherboard, but I ran Yosemite on it prior to this. GTX 760 I had to install using the Intel graphics, as com.apple.WindowServer was crashing on installation. I thought that I could boot to macOS afterwards...

I fell here, I had already put on the iGpu in the bios.
What to do?
Thank you for your help
