Stuck on easy flash menu

I tried to flash a modified bios (wirh nvme drivers) in easy flash on a n751jx laptop, and I’m stuck on the do you want to update BIOS menu, I’ts been half an hour, is is safe to reboot now and try to reflash it differently? If not what can I do?
Have I missed a step?


Yes, it’s safe.

Thanks, the computer rebooted normally.
