I have an OMEN by HP - 15-ce015no, which I have done no hardware changes to.
I was using the device as per normal, when I suddenly got a blue screen and the device powered down. On subsequently powering on I was met by "Hard Disk Error" "Hard Disk 2 (3F0)"
After enabeling legacy support, which simultaiusly disables Secure Boot, I was able to boot, but after a few minutes I was forced back to the black screen, but now it states "Hard Disk 2 (3F2)", and I have not been able to boot since.
When looking at UEFI Boot Order, under System configuration, all the lines below were grayed out and when entering on OS Boot Manager, the message "OS Boot Manager is not found." popped up. The same goes for Legacy Boot Order, where Notebook Hard Drive returns "Notebook Hard Drive is not found."
I have also tried to use a USB-stick as boot device, created with MacriumReflect, while an external HDD was connected by USB.
Are there any suggestions?
Regards and thanks in advance.
