Now I turn it on the following black screen message comes up.
Have you tried to select the boot manually? The BIOS/UEFI is pre-set to look after a booting file in the EFI folder on your hard drive. F9 used to be the boot option key. Press it at startup and see if it lets you to navigate into the EFI folder. You are looking for something like "bootx64.efi" in EFI/Boot folder. It's possible that after the system wasn't properly shut down the hard drive could use some repair or it's just a bug and it will be sorted after the next proper shut down. In case that the boot option won't show the hard drive and the EFI folder it must be repaired. Plenty of videos and how tos on youtube on this issue.
Up and Down to change option. ENTER to select an option.
Press F10 to BIOS Setup options. ESC to exit.
Also, i forgot to mention in my previous post, I can't seem to open the recovery manager. Pressing F11 has no effect.
I am having the exact same issue with a HP Laptp 15-bs0xx that also started yesterday.
