Can’t boot anymore into my hackintosh

I have a hackintosh for like 8 months and recently I couldn’t boot anymore into it.

The partition was there and everything seemed to be working, but from a blackout while I was on the hackintosh, it stopped working.

I searched and the only thing I was able to do was to insert the bootable usb and keep there while working on it.If I unplug the usb I can’t boot anymore.
