Hi folks. I bought a G505s, LA-A092P mainboard, running Windows 8.1. I tried to update BIOS from version 2.0X to 3.00. After the flash I got the following error on startup:
It says "Checking media," then says “EFI Network 0 for IPv6 (my MAC Address) boot failed.” Then a blue popup box saying, “Default boot device missing or boot failed,” and I’m prompted to insert recovery media and/or go to Boot Manager. Boot Manager wants me to select between “EFI Network 0 (MAC Address) for IPv4” or IPv6, and both of course just lead to "Checking media" again and then “No bootable device, please restart system.”
I can start fine in legacy. At first Winflash would not let me try the update again, because Winflash thinks the BIOS version is already 3.00. But I can go into Setup, under Configuration, and there’s an option called “BIOS Back Flash” and enable it, and then Winflash will run regardless. But it made no difference. I re-flashed several times, and I still get the same UEFI error as before.
I downloaded Winflash straight from this website, not a third party. I can post screen shots if it helps. I hope this sounds familiar to somebody? But I did not find ayone else getting this exact error with a cursory search of these boards. If anyone can tell me what I need to do, I would greatly appreciate it. -- Craig

Welcome to the Community,
Did you download the latest BIOS from the Support website? It seems that the laptop is booting from Network, instead of booting from HDD. Try a BIOS reset,
While in BIOS, press Fn+F9 / F9 to load default settings. After that, press Fn+F10 / F10 to exit saving changes. Let us know how it goes.

I went to default settings as above, and there was no change. There are only three options I can get to come up in Boot Manager:
EFI USB Device (my recovery USB brand name) (If I have it plugged in)
EFI Network 0 for IPv4 (my MAC address)
EFI Network 0 for IPv6 (my MAC address)
At this time, I cannot get any kind of HDD to come up as an choice in Boot Manager.
But if I switch to legacy, I can boot fine.

Sorry about that. Try this link instead https://support.lenovo.com/us/en/solutions/ht070218. We'll wait for your message later.

I get a not found link from that too. Here are a couple of ways I can check bios version outside of Setup, done while I am in legacy.
1. Go to Command Prompt, type: wmic bios get smbiosbiosversion
2. Right-click Windows icon --> Run, type msinfo32
Result: BIOS Version/Date = LENOVO 83CN53WW(V3.00), 1/8/2014
But I am starting to suspect there is, in fact, nothing wrong with the BIOS. I'll explain in next message ...

Consider the following message thread:
I bought this G505s a couple of months ago from a third party seller, not from Lenovo. I suspect that the seller went to erase the previous owner’s data, and re-built the software wrong, probably with the machine in legacy mode.
I noticed that after Winflash finishes, and the machine restarts, it starts automatically in default UEFI (i.e., the flash erases user settings).
I think that I was using this machine this whole time in legacy until I flashed v. 3.00, then it changed to UEFI, and that's why I'm only noticing it now.
I have an SSD that I was planning to upgrade the G505s with. It has no data on it yet, not formatted as far as I know. This machine did not come with a system image USB that I could use to recover from. So, it looks like if I want to use Windows on the SSD, I will need to download/buy a recovery CD.
Thanks for the help, you did inform me that the HDD was supposed to show up in Boot Manager, and that’s what led me to isolate the problem.
I will consider this problem closed.
