Problems installing w7 on fujitsu p558

Hello everyone and sorry for my bad English (I use a translator), I have a Fujitsu P558+ desktop PC and I need to install Windows 7 (not in VM), I tried without success to install it because it blocks when it should start the installation boot. Can you help me? My thought is that the cpu is not supported and therefore I have this block. Currently the CPU is an intel i5 9th Gen. Thanks to all

Welcome to the Win-Raid Forum!
The main problems for users of a modern mainboard to get Win7 installed are caused by not matching Win7 in-box ACPI and USB 3.x drivers. Unfortunately I cannot help you myself, but I hope, that you will get support by someone else.
Good luck!
