EFI Network error boot failed

On my Lenovo laptop with Windows 10 I suddenly started to get this error on boot that says:

EFI Network 0 for IPv4 boot failed.

To solve it, I loaded the Bios and I saw that my hard drive was recognized. In the Boot tab I changed the Boot Mode to Legacy Support and then the Boot Priority to Legacy First.

Then saved and quit.

My laptop then went into looping the Lenovo logo followed by a message stating that:

PXE-E61: Media test failure, check cable.
PXE-M0F: Exiting PXE ROM

How can I fix this? I don't understand why it suddenly started to happen...

Although your disk is recognized in the BIOS, it seems like it's not recognized as a boot device. Therefore the BIOS tries to boot from the network, which of course fails.

It seems like your disk has experienced a catastrophic error. In any case, there was no reason to change from EFI mode to Legacy, since your existing installation was probably installed in EFI.

If you have a Windows 10 boot media, use it to try and doStartup Repair.

If Startup Repair is impossible because it cannot detect a Windows installation on the disk, you should first try to save any data on the disk for which you have no backup. If you have a Linux Live boot media, this can be used for this.

The best next step in this worse case is to replace the hard disk. If you would rather try to salvage it, use the Windows boot media to reformat the disk. Use slow format, meaning not a fast format, which will take some time on a large disk, but may detect and mark the bad sectors. Install then Windows again, then check the disk health via its SMART data (one such utility isSpeccy) to see if didn't have too many errors to use safely.

Can you check the boot order ? It seems like your laptop trying to use the network to boot instead of using your hard drive
