Y50-70 boot up issue

I left my computer alone downloading an update for a game and when I got back it said there was an error 

So I restarted my computer and after the Lenovo logo pops up in the top left corner that says "Checking media..." then

EFI Network 0 for IPv4 (F8-A9-63-4B-25-6D) boot failed.
EFI Network 0 for IPv6 (F8-A9-63-4B-25-6D) boot failed.

I've tried opening up the BIOS and changing the boot up mode and boot priority to both legacy (as suggested in another forum post I was looking at), yet after I do that, my computer restarts and it goes back to another black screen. This time it says "No bootable device -- insert boot disk and press any key"

what do I do now?

Re: Y50-70 boot up issue

Hi Chaddiggans , 

 

Welcome to the Community Forums. 

 

I think there is a better chance restoring the BIOS to its previous settings.

The message is implying that the harddrive or Operating system is not seen so it was looking for the networks for a bootable image to launch.

 

In the BIOS check if the harddrive is still being detected and perhaps reseating (page 39 -remove and reseat to its place making sure that contacts are good) it would help . 

 

Testing the harddrive integrity on another computer or through a data enclosure to see if it's still ok.

You may also boot on a live media to check and perhaps take the opportunity to back up if needed.

 

Update us how it goes.

 

Regards

Re: Y50-70 boot up issue

According to the BIOS my computer still recognizes my hard drive. 

I think it may be a physical error because my laptop is damaged along the hinges  but it has been fine for the pasr almost 7 or so months.

If it is a physical problem then I am unsure of how to transfer or even check the integrity of my hard drive if I cannot get past the boot up

Well I just finished taking apart and reseating my hard drive, but the same error occurs. 

Is there anything else I can possibly do?

Hi Chaddiggans , 

 

So would the harddrive show in the BIOS?

If no HDD detected even on the BIOS then you can try another harddrive or test the original hdd on another.

This would at least give you idea about its integrity (highlighted link above would give a good reference in checking ).

 

Regards

Re: Y50-70 boot up issue

I forgot to mention 

Yes it does show the original hard drive on the BIOS so I guess it can recognize my hard drive but is unable to boot from it or something

Re: Y50-70 boot up issue

Hi Chaddiggans , 

 

Greetings. 

 

 

Try to turn off and then access BIOS using the same novo button .

On the exit tab , load defauts and save and exit.

 

Here we would expect that it would revert back to security tab , secure boot enabled, Boot tab UEFI enabled , Exit tab OS optimized on current Windows to check.

 

Else disable secure boot from security tab then save and exit.

If same issue , try BIOS backflash on the configuration tab to revert to previous version.

 

Finally if we do have a bad hardware or BIOS configuration after all the steps we have tried (even if BIOS would detect the harddrive) , best to call in technical support for in warranty repair. 

 

Regards
