Lenovo G50-30 Laptop: Checking Media, EFI Network Boot Failed, Default Boot Device Missing

Hello! I have a Lenovo G50-30 laptop, I have such a problem with it.
My computer crashed so I turned it off and closed it, I left the house, when I came back I opened it and it is still on but there is nothing on the screen. I turned it off and turned it on again and then there was a problem.
Well, when the system is started, after the standard appearance of the manufacturer's logo on the screen, the system does not start, and the message '' Checking media_ '' appears. Then a blue rectangle with a black background appears in the center of the screen with the message `` EFI Network 0 for IPv4 (68-F7-28-30-9D-21) boot failed ''. I need to enter a few, of course, again '' Checking media_ '' and then another error, but with a bit of different content '' EFI Network 0 for IPv6 (68-F7-28-30-9D-21) boot failed '', after the next message appears - '' Default Boot Device Missing or Boot Failed. Insert Recovery Media and Hit any key. The select Boot Manager to choose a new Boot Device or to Boot Recovery Media ''. I click enter and the Boot Manager window appears. In the Boot Option Menu I have two options to choose from: '' EFI Network 0 for IPv4 (68-F7-29-30-9D-21) '' or '' EFI Network 0 for IPv6 (68-F7-28-30-9D -21) ''. Below, of course, the two selection arrows (up, down) to change option, ENTER to select an aption. After pressing enter on the first option, the message `` EFI Network 0 for IPv4 (68-F7-28-30-9D-21) boot failed '' appears, then I click enter, the message `` Checking media_ '' and the message about same content, I click enter again to get the message '' EFI Network 0 for IPv6 (68-F7-28-30-9D-21) boot failed '', enter and the message '' 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. '' After that, I could see Boot Manager on the screen again ... And you can do it over and over again. The laptop is not equipped with the One Key Recovery button, it sees the disk normally, which I have read in other cases, was so that I could not see it and I am now in a point. The recovery system also does not work, an error pops up, that I should put a system disc that I do not have because I bought a laptop with an already installed system.
What the hell is going on here?

Where did you check that it is visible?

If there is such a message, you should either get such a disc with the laptop (despite the fact that the system is loaded) or you should burn it yourself after buying the laptop.

Express yourself :)

Take out the disc, put it back in, see if it is visible in the bios / uefi.

I checked it in bios that the disc is visible Uefi, I saw videos on YouTube where others were switching uefi to legacy first or something like that, I did nothing, it did not help.

The system is most likely damaged, you need to reinstall it. Do you have win10 license?

Yes, now I have win 10. I had Win 8 before, but I updated to 10 because I already had the system preloaded on my laptop. Is it possible to try to do this without losing data on the disk, or to get them out of there somehow?

The easiest way is to connect the disk to another computer / laptop (regardless of whether it is via a USB or directly SATA adapter), then download the data, install the system from 0 (the license / system code is sewn into the motherboard's bios).

From here you can download the program, insert a minimum 8GB USB flash drive, then download the system with this program and install the system from USB.

In a few hours a friend with the second computer is to come to me, we will switch disks, copy the data and try to reinstall the system with this program according to your instructions. After completing these steps, I will let you know if it has worked. It is strange that it happened "just like that", for no specific reason, I do not download too many things from the Internet, I do not have any computer games, I only use the Internet on this laptop and watch movies on it, hence my surprise .

The disk itself may be damaged, you will not confirm it without a test. You can quickly check with a friend using CrystalDiskInfo if there are any errors in SMART.

OK, I will.

we connected this disk via usb, you can hear that it works but the computer does not see it for a long time and then it suddenly sees it, shows the recovery partition in my computer, i.e. you can see the capacity of the partition, how much data is occupied but the main partition cannot be seen this way, the bar on my computer shows as if something was loading, probably the data from this partition, and then when the bar came to the end, the computer stopped seeing it, it was audible as if the disk stood still.

It is very likely that the disk is damaged; / you would have to check it, e.g. MHDD https://www.elektroda.pl/rtvforum/topic868490.html

okay, I didn't have such important data, but now the question remains, will I get my system back, my key to it? because it was on the disk, and if the disk is damaged, what next?

I wrote to you before, the key is sewn into the motherboard

Ok, to sum up, make a usb / dvd installer, reinstall the system while reformatting the disk and see if it works.
I have a question, if I do the usb windows installer on my friend's laptop, will it work on my laptop? and will this key be automatically loaded from my laptop or do i have to extract it somehow?

First, I would check if the disk is functional, because we do not know it, it may turn out that it is not, then reinstalling the system will not do anything.

Yes, and yes - the key will be automatically loaded during installation.

Okay, now it's a question from a different barrel because I tried to reinstall the system without data loss and data loss and I can't see any partition at all. My question is as follows, I have another disk but it is from the hp computer and there is recovery from the hp computer, will it be possible to remove it? will it be possible to do recover from my computer, ie lenovo on this hp drive?

I moved the disks and now the installer requires the product key from me, how should I give it to him if I do not have it?

Skip it and then activate it from the system level.

You can't skip it, I only have the next button and if I don't enter the key, I can only turn off the installer. this is not because there is recovery from hp from another system? I can somehow remove recovery, format the entire disk to zero?

You can, it would be best to format it by a program run from a usb flash drive, it could be mhdd. Do you install the entire system with a pendrive?

Yes, I used this program as you recommended, and at a friend's computer I downloaded it to a pen drive.

edit:
This is what the image in which I am stuck looks like and I don't see any way to skip what you say

The first time I see something like this and I used this tool several times, the key was always taken from the CD, try the newer version of the media creation tool.

Have you downloaded win 8.1 on this flash drive or windows 8?

In what you sent me mediacreationtool there is a choice of wines 8.1, wines 8.1 n, wines 8.1 pro and wines 8.1 pro n. I have probably downloaded the wrong version, so I cannot see the key. there is no windows 8 to choose from.

Ok, the question is just what version did you have exactly the same must be downloaded.

I bought my laptop in 2014. I don't know if it had 8.1 or 8 but it comes out unless 8. is there any way to find out what my system was installed at the beginning? e.g. on a box?

I was with the disc in the service, over 300 sectors destroyed, no longer good for anything. And with this installer the idea was that I downloaded windows 8 and I need to download windows 10 and then the key downloads itself. thanks for the help!
