I dual boot Windows and Tuxedo OS

I used Windows to do the BIOS update and now grub is showing this weird screen, what do I do?

I'm using a Lenovo LOQ with an intel core i5 and an NVIDA GPU (if that helps)

First thing try restarting into the bios/uefi then from there boot into windows and restart

#

If that doesn't work try running boot repair from a usb drive

mint meteor First thing try restarting into the bios/uefi then from there boot into windows ...

I went on Windows and it seems like Lenovo Vantage had something else it needed to do on there

#

Now Windows is the default boot option (which happens everytime I do BIOS updates)

I'll try to switch it back to Linux and see if it works

Windows likes to play god with your pc and often times it breaks something

It seems like grub is still having issues

#

Still showing that same page

#

I'm surprised this is happening considering Windows and Linux are installed on 2 separate SSDs

Then restart into bios again and check if the linux drive/partition is set as the main one or if it got reset after the update. if it got reset to the state of windows being the main boot change the boot order and check again

I did change the boot order

#

But grub is still showing that same screen

Check if you have the secure boot on it might be the source of your issues. BUT if you have it find your bitlocker key AND WRITE IT DOWN before doing anything to prevent being locked out of your drive by windows

#

It's a last ditch effort really so try to avoid it until necessary

finite granite Apr 9, 2026, 6:32 PM

#

It says secure boot disabled

#

Okay then go grab a usb drive with a tuxedo iso installed and ready to go as a bootable system and within that system run boot repair and hopefully it'll fix things

#

I have a USB drive with Tuxedo on it, but it's not the latest version, would that still work?

mint meteor Apr 9, 2026, 6:35 PM

#

Hopefully it will. If it doesn't work, go into windows and yeet the newest version on the drive and then run it again

#

For some reason when I inserted the USB inside it booted into Linux, like not the liveUSB one but my actual installation

mint meteor Apr 9, 2026, 6:37 PM

#

Okay then, now take the usb out and try to run it again

#

Ofc turn the pc off before taking the drive out

finite granite Apr 9, 2026, 6:38 PM

#

I clicked on the BIOS boot menu to boot from USB it instead booted my installation

mint meteor Apr 9, 2026, 6:38 PM

#

Sometimes stupid things fix the issue

finite granite Apr 9, 2026, 6:39 PM

#

I restarted and it seems to have gone back to normal?

#

Seems like the issue is fixed thanks to inserting the USB drive and not doing anything?

mint meteor Apr 9, 2026, 6:41 PM

#

It might be that the usb provided grub with the files that got accidentally wiped somehow and jumpstarted the further checks that allowed the system to write them back into place during the booting procedure

finite granite Apr 9, 2026, 6:42 PM

#

That's nice to know

#

I'm glad I had that USB lying around then

#

Also thank you for your help

mint meteor Apr 9, 2026, 6:43 PM

#

sometimes the files might get damaged for no reason and the usb allows the boot program to read the correct versions and save them into the main drive

mint meteor Apr 9, 2026, 6:43 PM

#

finite granite I'm glad I had that USB lying around then

I always keep the usb with the iso on me for the reason of unexpected troubleshooting
