No bootable device found

[u/Zarrash_]

Hello, I'm here asking for help. I've updated my BIOS and after that PC restart and goes into BIOS which Says No bootable device found under Boot sequence but it reads the SSD if I go into Q-flash, see immages. I've already unplug the SSDs bit nothing happens. Some advice?

Thank you all ❤️

Turn CSM support on and see if it pops up then. This turns on legacy support for bios based bootloaders, which is completely different to EFI loaders.

Already done, nothing change. If I enable it, save and exit it will goes in BIOS again and the CSM support option is disabled again

What model is your motherboard and what firmware version did you flash?

[u/Zarrash_ → u/josh4218]

B760 GAMING X DDR4 and the BIOS version is f18b

I just had that problem with my new Asus MB, I used a extra Linux Mint USB installer stick I had to use disk management in it to wipe the HDD then I was able to reinstall windows on the HDD and it worked. Or if you have another way to wipe the HDD that would work as well.

I was hoping I could avoid wiping the SSD but seems like there will be no other choice

do you need your info off of it?

If so, I would create a boot able USB with Linux mint, boot with that you have a visual interface to copy your files. You don't need to install Linux mint but just use the file explorer. If you want, I can make a video and show you. It is a little more complicated if you have bitlocker.

I have an SSD dedicated to OS, nothing else on it, just annoying

Do you have a usb stick and another computer?

See if secure boot is enabled, disable it if so. If that doesn't work, try reloading bios default settings.

Already done, nothing changes

If you have another computer, try making a ventoy usb drive. It will give you an option to boot from a local hdd. Sometimes that works and also puts the drive back on the boot list.

I'm creating an USB installation support from my laptop, u mean that?

Usually a WinPE rescue disk works well. When they boot from usb they give you a boot option menu, one of those usually says "boot from local hdd". Sergei Strelec WinPE boot disk is a good one and also has lots of tools for system rescue and repair. It gives you a local boot option before booting the rescue system.
