My Laptop is having stuck loop problem during hp boot up. I have tried the standard restore and even troubleshoot. But i found one solution on the net that use your windows key and B together to update BIOS , which say that it is writing new BIOS image. After i do this my laptop dont get stuck on hp logo again. However when i shut down laptop, the problems returns i.e Loop getting stuck on HP boot. I have also reinstalled new windows but the problem is still there.
