My y510p suffered a similar failure message as it's HDD failed. I fitted a new SSD and installed W10 along with all the drivers and apps from Lenovo and it's back in operation.
The "EFI Network" message is informational only. It is not a failure and will not lead you to the failure.
Also, do NOT change boot mode to legacy as a fix. Good way to corrupt a drive in the process.
As to SSD, non-SSD (that's a HDD) and Hybrid you could research all that but to me it sounds like the typical failed boot drive. Be sure to set the BIOS back to stock then see if Windows will try a repair. If not, boot your W10 install stick or DVD and try a repair from there. Tutorials on how to make the W10 install and repair stick are on the web but I use Microsoft's Media Creation Kit all the time.
I’ve had my laptop for well over 5 years now. I’ve never had a problem that caused me to not be able to even boot it up until now.
I don’t know how it happened. I went to go restart my computer, ya know click the Windows key and then select “restart” from the power options menu - but it wouldn’t let me do it. I clicked restart a couple of times and it just wouldn’t work. So I figured I’d just do a manual shutdown and press the power button. When I went to turn it back on I got a black screen with a blue box saying “EFI Network 0 for IPv4 (F8-A9-63-4E-CC-49) boot failed”..
Naturally I immediately googled the issue and tried the following solutions:
• change boot setting to Legacy Support which only resulted in PXE-E61: Media Test Failure, check cable.
• Disconnected battery, held power button for 20 seconds. Nothing happened.
• Open boot/BIOS menu and reset to default settings, disable one setting that had to do with PXE to LAN (I cant remember specifically and I don’t feel like digging back through forums to find it) and that didn’t work.
My hard drive is still detected. Or I should say under “Hard Disk” it says “ST500LM000-SSHD-8GB. I don’t know if it matters but my computer is a hybrid so it has both a SSD and a non-SSD (not too well versed in computers so I dont know what thats called)
I’m running Windows 8.
I don’t know what else to do. Any help would be greatly appreciated.
