Question

Iron

Couldn't reset bios password. And I decided to reflash, successfully reflashed, it turns on and comes out checking media .. and shows Efi Network 0 for IPv4 boot failed. I press ok and then Efi Network 0 for IPv6 boot failed I press ok writes 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 inserted a disk with windows, it enters the boot manager and then only 2 efi network then comes out No bootable device -- please restart system Nothing else. By the way, the BIOS password remained. Yes, I'm curmudgeonly. Help how to solve this problem

Answer 1

It seems simple and easy, without knowing the password - it can not be solved in any way.
After flashing the BIOS settings were reset to default. By default, the boot is in Efi mode.
Before flashing, there was BIOS mode, the first device was a disk, and the disk was formatted in BIOS. Now the system does not see it and does not boot from it. Goes to download from the network - and also can not.
You need to remove the disk from the laptop, connect it to the computer, save the information on the computer, put the disk back in, reinstall Windows. Something like this.

Answer 2

Contact the official service with a laptop, they should be able to reset passwords.
And grab documents confirming ownership of a laptop, just in case.
