EXITBS:Start opencore

I've followed the opencore laptop guide (without mac) and got the Bootable device ready. After booting from the usb and selecting "install macos base (external)" I get This exitbs:Start error .

I've done the things mentioned in the troubleshooting section in the guide regarding the same but no positive result.

P.s. I'm a newbie to this hackintosh stuff

Device : Lenovo legion y540 Specs : I5 9300h; 8GB 2666mhz ram; Dgpu gtx 1650; 128GB SSD; 1 TB HDD
