VN7-591G boot issues after BIOS update.

simpy3 · February 2016

I just updated to v1.15 and the first time booting after, I just got "No bootable device" after the logo screen. I managed to circumvent the problem by switching from UEFI to Legacy.

I was wondering if anyone else had this problem and found a fix? I would prefer to be using UEFI again.

Specific specs:

Core i5-4210H

GTX 860M (4GB)

12GB RAM

60GB SSD (OS)

1TB HDD

I'm thinking maybe the SSD could be part of the problem? Just an idea.

Can you post a screenshot of the SDD partitions?

which version of windows is installed?

Windows 10.

Looking at this screenshot, your system was installed using Legacy, so it's why it didn't boot using UEFI settings.

if you want to use UEFI, you need to re-install windows 10 from scratch and setting BIOS to UEFI.

I have the exact same issue as the original poster and all I did was update to that 1.15 BIOS. (Trying to track down a video blue screen).

Before I updated the BIOS, I was using UEFI mode perfectly. After the install of the 1.15 BIOS, it failed and I had to switch to Legacy.

Something in that BIOS is off.

Can you post a screenshot of Disk managemento too?

it's strange that a BIOS update can erase an EFI partition.

Are you sure your BIOS had UEFI set before BIOS update?

I am currently investigating these reports and will provide an update as soon as I have additional information.

My disk layout is EXACTLY like Simply3's.

I did a clean install of Windows 10 on this system with a copy from MS, so this wasn't some upgrade from Win7 or XP.

And the only reason I knew it was a problem was because upon reboot from the BIOS, I got the "No bootable device" screen. Went in and HAD to set it to Legacy and it worked fine.

I couldn't figure out why a BIOS update would kill a boot table or EFI partition
