No boot device

[Maiaseonaid]

Hi I’ve come across an issue with my laptop one day it was working fine and then the next I got this error on my screen “boot device not found. Please install an operating system on your hard disk. Hard disk (3FO). F2 system diagnostics.” 

So so far I know how to get up a startup menu with the options of “F1 system information. F2 system diagnostics. F9 Boot device options. F10 BIOS setup. F11 system recovery.” 

When i I go into system diagnostics I get this menu titled HP PC Hardware Diagnostics UEFI, then a smaller title “version 1. 17.0.0 - BIOS. 

menu options are “memory test, storage tests, language and exit”. 

When I go onto memory test it just starts up the memory quick test which takes 37 minutes. When I go onto storage tests I get two options quick check and extensive check and when I click on those it does nothing and takes me back to the main menu on the diagnostics. 

I read up about a solition online going to the F10 option and changing the legacy support to enabled and I did that but this message of insert boot device and press any key came up and if you pressed a key it repeated the message. 

Idk what to do as before this error showed up it had been asking me to update the laptop for a while but I didn’t have enough space then this message showed up so I don’t know if that helps but anyway if anyone has ideas to help me let me know! Thanks.
