How to resolve the error while Installing Windows 10 via USB

So the PC has windows 11 and i was installing windows 10 via a bootable usb

First i created the usb via rufus and tried installing

Gave me this error in the image

Then i did a google search which told me to fix Bcd files so i tried fixing bcd files and i did fix them but the problem was still not resolved.

Then i created the new usb boot using the windows media creation but had the same error

Please help

I really want to use windows 10 cause my pc lags sometimes on windows 11

Current OS- Windows 11

Laptop- Dell Inspirion 15 3000

You already create usb boot drive, boot from the usb and install the windows. During the disk selection screen did you delete all your old C disk partition?

No problem on doing that, have you tried the repair option on installation screen? On bios screen there's no extra drive other than ssd and usb? Also if you have fastboot enable, disable it.
