Hi this error came up on my ideaspad I did the f2 and got the page attached . I can't scroll down to click on the hard drive however it is not giving me this option. What do I do?

I am not an expert in this matter. I had the same problem. None of the above solutions worked for me. Then I tried to change the BIOS setting to LEGACY mode. And the computer was able to boot. Give it a try.... If you still fail, then what can I say.......you can always return to its previous UEFI mode.

I have a problem becouse i have an error after changing one thing in BIOS i changed the boot legacy to eufi and when i power up my laptop it says EFI Network 0 for IPv4 (50-7B-9D-D2-94-DA) boot failed and i click enter it says again same thing but IPv6 and when i click enter again it says again same thing but IPv4 again and again when i click enter it says EFI PXE Network boot failed after clicking enter again it says Default Boot Device Missing or Boot Failed. Insert Recovery media and hit any key then select boot manager to choose a new Boot Device or to Boot Recovery Media what should i do? I have laptop ideapad y700

Had a similar issue and solved it. First drain the bios as the guys above suggest. Reconnect everything and power the laptop. Navigate to the Bios Setup on start (the nova button will work or repeatedly pressing F2). Scroll right to the "Boot" section. Under the Boot menu, check the "Boot Mode". With the issue above, your boot mode might be on UEFI, change it to "Legacy Support" . Press F10 to save changes, make sure you confirm with "Yes" on the pop up screen and your laptop will start like normal.
