about half a year ago i installed windows 11 on my lenovo ideapad 3 chromebook using coolstar.org as a guide everything worked up until i chose to install ubuntu after whipping the win 11 install after using ubuntu for about a week it crashed and wont boot anymore i can go into the boot options but every bootable usb i insert it does not show up even a fresh win 11 installer didn’t work is there a way to fix this since i do not have access to any os and all i can do access the uefi shell
