Opencore problem when i boot without USB

[aliens72]

Hi, i've a fresh install of High Sierra on a legacy notebook, and everything works well.

When i try to boot without USB i have a problem of no system found.

I've copied the EFI from USB and launched the bootloader command to my HDD.

Where is my mistake?

If you're booting using a legacy notebook its likely something to do with that.
Maybe your drive has been formatted to using MBR partition?

Make sure it is formatted instead using GUID partition and using UEFI booting in BIOS (if possible)
and that also your USB stick's EFI folder has been copied to the EFI partition of said hard drive.
