Hello everyone !

I recently shut-downed windows normally, when it decided to update before shutting down.
From now, when I power on my laptop, it stays stuck on the MSI logo at the very beginning for ever.
I cannot access BIOS at this point or do anything.

I tried without DRIVES, then it goes through the MSI logo and get stuck on a not flashing white dash (underscore) in the middle (a bit left) of the screen.
When I hit the BIOS key when booting, the black screen with the white dash appears immediately.

I have Ubuntu with grub on a SSD and Windows 10 on a HDD. I get stuck the same with any drives.
What's weird for me, is that I can boot on a Ubuntu Live USB (I'm writing this post with it on the very computer I have this issue). In order to boot on the Ubuntu Live, I had to removed my drives so it isn't stuck on the MSI logo.

It feels like my BIOS in corrupted or something ?

I went through a powercycle, disconnecting the battery and the power adapter then holding the power button for a minute, without success
I disassembled the laptop to disconnect the CMOS battery in order to try to reset the BIOS, without success.

I am wondering if this issue is related to the fact that Windows updated before shutting down, knowing that Microsoft has the ability to update firmware via a Windows Update.
Maybe is there a way to flash the BIOS ?

Here more info:
_ laptop: MSI GE60 2OE (2013)
_ OS: Windows 10 on HDD and Ubuntu 18.04 on SDD with GRUB. Ubuntu Live USB is 16.04
_ I'm pretty sure the BIOS is on legacy, but I'm not sure about fastboot and secureboot though I guess they are disabled.

Thank you for your help !I ran into a similar issue with an ASUS laptop I had. Basically the UEFI is working with the Windows OS and you have to tell Windows to give access to the BIOS back. Even with a trashed install of Windows the BIOS through UEFI only allows Windows to make changes and not the user at a POST option to get there.

So the Windows installation is trashed and the only boot is USB?

You can request the recovery media from the manufacturer and that would work with the UEFI lockout that is going on to be able to install Windows onto the hard drive or SSD again. If computer is still under warranty this might be free. If the computers warranty expired it might be like $40 USD to get the recovery media. If your computer was originally Windows 8 and you upgraded to 10 before Windows got trashed, you could use the recovery media to install 8 fresh and then from within Windows 8 tell Windows to give BIOS access back to user so that the UEFI lockout is no longer happening. My laptop came with Windows 8 and I ran into this issue when trying to downgrade it to Windows 7 and couldnt get into the BIOS. I basically had to tell Windows 8 to disable UEFI and give me access to my BIOS. Once in the BIOS I then was able to set boot order to allow for an optical drive to be at the top of the boot order before the HDD and this then allowed me to install Windows 7 clean to it. What STINKS is that if you blow away the Windows installation on the computer before making this UEFI change it is then locked out of being able to install anything on it other than the original install that the manufacturer made for it which is a headache. Hello,

I make sens.
A good thing I saved the recovery media on an external drive 5 years ago and I still have it !

I am waiting for a sata adapter to plug my HDD on usb to backup my data. Then I will try a clean install of Windows 8 on the HDD.
I will keep you updated.

Thanks a lot !Hey I have some info !

So I received my sata and msata adapter.
So now I am able to boot on my Ubuntu SDD via the USB adapter. The BIOS is still unavailable...

I also tried to boot on my Windows10 HDD via the USB adapter. It goes into repair mode.
From which I have tried to access the UEFI BIOS without success, it goes again to this non flashing white dash.
I tried to restore the previous version, before the update which crashed the BIOS, it doesn't work. I guess it is because the HDD is connected via USB ?

So what I am thinking of doing it to try the reinstall option. Though again I don't how it will end since the HDD is connected via USB.
I have also recover the manufacturer recovery media (on a USB stick). I tried it but it doesn't work without the HDD (of course, but I thought maybe it would recover the BIOS or something). I still have to try with the HDD connected via USB.

Another option I am considering is to boot on the recovery media, then hot swap the HDD on the mother board and try the recovery.

When booting on my Windows10 HDD via USB I can access the Command Prompt. So a solution I might try first is the following:
Code: [Select]Type BOOTREC /fixmbr and press the enter key.
Type Bootrec /fixboot and press the enter key.
Type Bootrec /scanos and press the enter key.
Type Bootrec /rebuildbcd and press the enter key.
Type "A" to add the installation to the boot list and hit enter.
Exit the command prompt with the X button on the top of the window.
I won't have the time to work on all those options until MONDAY, so if you have some tips in your mind you are welcome !
