legacy BIOS based PC, in order to boot, it require some system boot files in the boot sector of your system boot drive

for your new SSD, run the clover installer again, the installer will copy the boot files to your SSD, then you can copy and paste the EFI folder from your USB installer drive to your SSD root directory

read the Clover wiki for more information

take a look your USB Clover EFI installer log, you may have some ideas

  • the cause is the Mojave System SSD lacking a properly installed EFI_CLOVER File structure with a properly created config.plist.
  • If your EFI_CLOVER File Structure and config.plist in the SSD is the problem, you can boot using macOSMojave USB Installer to Clover Boot Manager(CBM) screen and switch to macOSMojave SSD from CBM and
  • After login to Desktop, mount the EFI partitions of both Mojave USB Installer and Mojave SSD system disk [Using Clover Configurator Clover Configurator 5.3.0.0 (Global Edition) or EFI Mounter v3]
  • Navigate through mounted EFI from Desktop and delete the EFI_CLOVER from the SSD and then
  • Copy and paste the EFI-CLOVER from the macOSMojave USB Installer Disk to replace the deleted EFI of macOSMojave SSD, and then
  • Reboot the macOSMojave SSD as first boot Device from BIOS and again from F-12 boot menu.
  • Boot Mojave System Disk from CBM screen in Verbose Mode to see if the problem is fixed.
I follow your steps boot from from USB, select macOS disk, copy file CLOVER folder from USB to SSD but when i try boot from SSD clover loads but it can't sees boot partition btw mouse and keyboard not working
