efi network 0 for ipv4 boot fail

Hello guys. not sure if this is the right forum but if it isn't, redirect me somehwere else.

but I have this problem and hope one of you can solve it. I have lenovo p500.
It had been running without giving me a single problem until today. It had been running just fine until 30 minutes ago, the whole screen just froze on me - not a problem.

It happens sometimes and all i had to do was simply restart and I will get back on track but nope - black screen shows up with a message "checking media"
then it would fail then a blue screen would say
"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"
then it would take me to Boot Managaer where it would give me only two options
"EFI Network 0 for IPv4 (B8-88E3-8F-4D-B3)
EFI Network 0 for IPv6 (B8-88E3-8F-4D-B3)"
none of them works. Please help.

Re: efi network 0 for ipv4 boot fail

hi mafew,


Welcome to the Forums.


It seems like the HDD is being bypassed and the unit is booting directly to the network. Can you try to:

1. Boot into the BIOS (press Fn+F2 on power-up) and check if the HDD is getting detected on the Information Tab.

2. If the HDD's detected, navigate to the Boot Tab and ensure it's the first boot. If it still fails, try to disable UEFI and press F10 to save and exit.

If the HDD's not detected, you may need to contact lenovo for service as there's most likely a defect on the HDD.

Re: efi network 0 for ipv4 boot fail

Hi, i can find my HDD in the info section but when i go to the boot section it does not look like the picture, instead it says:

Boot Mode [UEFI]

USB Boot [Enabled]

PXE Boot to LAN [Enabled]



EFI Network 0 for IPv4 (F0-76-1C-1B-F6-01)

EFI Network 0 for IPv6 (F0-76-1C-1B-F6-01)


and thats all no UEFI boot for me to disable


What should I do?

Re: efi network 0 for ipv4 boot fail

Hello and welcome,


The symptoms described above point to a bad or corrupt main drive.  The "resolution" is an OS reinstall/repair in the case of corruption or replacement of the drive if it has failed.


Have a look at neokenchi's reply above and respond to those questions.  That should help identify what is wrong.

efi network 0 for ipv4 boot fail

My problem just appears in a blue box saying ‘EFI Network 0 Fo IPv4 (68-F7-28-9F-BF-04) boot failed‘. I’ve tried everything that I could find on the forums I’m not sure what to do

Re: efi network 0 for ipv4 boot fail

I have the same problem. My drive is detected in both the BIOS Setup and BIOS boot manager. I have a Lenovo ideapad flex 15. Is there a way to disable booting by network? There is no disabling option on my boot manager. It just shows the booting options as seen in the pic.

Re: efi network 0 for ipv4 boot fail

You need to change the boot mode (eufi) either to legacy or your hdd name, this should solve the problem!
