Lenovo Y50-70, błąd EFI Network 0 for IPv4 (F0-76-1C-FC-56-7D) boot failed

Hello,

I have a problem with Lenovo Y50-70, the laptop starts up, but the following things occur when starting the laptop:

Checking media... (it`s like this for about 5 seconds in the upper left corner)
Then:

EFI Network 0 for IPv4 (F0-76-1C-FC-56-7D) boot failed.
I click [OK], then:

EFI Network 0 for IPv6 (F0-76-1C-FC-56-7D) boot failed.
I click [OK] again and the following window appears:

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

I click [OK] again
and the Boot Manager window pops up, where I can choose,
EFI Network for IPv4....
and
EFI Network for IPv6
I click on one of them and it still shows the same thing

I think someone overwrote my MDR and the System won`t boot

I fiddled with the Bios, switched booting from UEFI to Legacy Support, unfortunately it didn`t work,
however, another error was displayed.

My guess is that I have MDR overwritten in the system,
Moreover, I connected a bootable Pendrive with Windows 10,

The installation from the pendrive started automatically, I clicked Install Now,
and at some point during the installation, the installer asked me where I wanted to install
System, I clicked Disk 0, (i.e. 256GB SSD), but what surprised me was that
next to the inscription Disk 0 there was an inscription 0.0 MB and at the top it was written that the total memory was 0.0 MB.

I got stressed and turned off the installer and then the laptop using a physical button,
I turned on the laptop again and the screen turned on with 4 windows and a circle at the bottom.
Then the Windows 10 installation started, the wheel kept spinning for 15 minutes with no effect, and I didn`t turn on the laptop from then on.

Thank you for all your support and help,

Regards,
Igor

I am sending images from the event.

Is the SSD functional? I had the same experience as you did with the disk that had errors/bad sectors on the disk.
Is Secure Boot disabled in the BIOS?

Yes, I have Secure Boot enabled in Bios.
Edit: And as for the disk, when I disassembled the laptop, I saw that it was an SSD from Transcend, and from what I heard, these disks do not have good bones

Please disable Secure Boot and try again.
Legacy Support - I only enabled it when installing Windows 7. Please restore the BIOS to factory settings and uncheck/disable the Secure Boot option and see if it helps.

Unfortunately, the same :/
Edit: Now it says Windows Boot Manager boot failed.

Well, now you insert the pendrive and install the system

My bootable pendrive is now getting ready because I formatted it

I inserted a pendrive with Windows 10 and the circle keeps spinning :/
However, EFI says EFI USB Device (Generic Mass-Storage)
