Usage COREL (BDUtility.exe) in Legacy BIOS for old windows

I am a new visit to the forum. Ignoring how to start communicating with Author Morbius (ABOUT CLOVER). Please help me, if there is no one.
Hello!
OS NAME: Microsoft Windows 7 Ultimate,
Version: 6.1.7601 Service Pack 1 Build 7601.
BIOS Version (Legacy): American Megatrends Inc. 1303, 2008.12.16,
System Model: P5k Pro.
Two discs: SSD (MBR) and HDD (GTP).

I want to install Win 11 on the HDD disk using Clover. On HDD installed Win7. By setting HDD in BIOS in the first place: black screen and white pulsating dash, but Win7 opens. SSD is fine, installed Win 10.
I learned from your forum (author Morbius) that you need to install on old versions Early Clover. I downloaded Clover.zip with you, but I have installed (out of ignorance) Clover Latest (V5120} does not work. It appears ‘6’, after a gray screen with DEVICE Manager, Management, etc. After that, Sandisk in BIOS stopped seeing USB. What to do with the old Clover - delete (I don’t know how), or load Up your old Clover (v4961). And one more problem: I found a warning that on very old versions, instead of the figure ‘63’ should be ‘4096’ I am bothering. If there is a possible, I will thankful.
