I had Ubuntu installed but I had to uninstall it and tried to delete the grub, but Ubuntu still appears in Boot Manager.Later I tried to install Ubuntu again and I cant access it now.Grub shows :

no device found, press any key to reboot

When using a live USB with Ubuntu I tried to install the grub, but I am getting this message:

warning this gpt partition label contains no BIOS boot partition; embedding won't be possible

  • The BIOS boot partition is only needed when the disk has a GPT partition table and the CSM (Compatibility Support Module) is enabled in the firmware, i.e. it is compatible with the legacy BIOS. Disable the CSM to get rid of this problem. – Johan Myréen Jun 16 at 4:34
