CompTIA Linux+ (XK0-004) — Question 279

On a UEFI-based system, which of the following invokes GRUB2 from the EFI command prompt?

Answer options

• A. boot//EFI/grub2.efi
• B. EFI/grub2.efi
• C. /boot/EFI/grub2.efi
• D. /grub2.efi

Correct answer: C

Explanation

The correct command to start GRUB2 in a UEFI environment is '/boot/EFI/grub2.efi' because it specifies the correct directory structure for UEFI boot files. The other options either have incorrect directory paths or formatting that does not conform to UEFI standards.
