I have an Acer Extensa 215-52 laptop and I don't see the legacy bios option on boot mode in bios, and no, I have a Windows 10 installation. I just want to install Windows 7 for my youtube channel, Please help me.
Also i tried on the latest version of bios, should i try with the oldest?

The easiest is to make the old Windows 7 MBR (Legacy) system accessible on an GUID (GPT) Windows 10, is to put it on a removable drive. You don’t need to dedicate an entire volume to the archive – your VM is stored within a file, rather than requiring a bootable disk.
Or can go the route of The rEFInd Boot Manager method, which more complex and unnecessary for what you want to use Win-7 for.

Has it Works?
Also you don't need Legacy for Windows 7 as long as you are at sp1 or later. One of the features added in sp1 was support for UEFI boot.
The USB won't be detected by my F12 menu because I need to have my boot mode on legacy bios 😔
You don't need legacy mode unless the OS you are trying to boot from is older than Windows 7 sp1. You stated you were trying to boot into Windows 7, just make a UEFI bootable Windows 7 image from sp1 and you should be good to go.
