iMac install issues

On a 13,1 iMac when iam installing sonoma latest using the latest oclp, it’ll go through all the loading bars and stuff but eventually it stops on one loading bar, stays at abt 50% of that bar and just stays there (note this happened to me before I reinstalled too, so could it be that maybe my drive did not get erased and instead it boots into my current drive by mistake during setup)

also i erased my disk when i was trying to install, since it didnt install and was stuck, i force rebooted it, but even without the usb its still booting and when i press option key during start up it still shows me. efi boot and macintosh hd, shouldn’t it not show anything or atleast the efi boot shouldn’t be there ?
