To switch to a new Linux kernel, you have to reboot your operating system and boot into it.

GRUB2 is also where you can choose between your installed Linux kernels. Press Escape or reboot your computer to leave the memory-testing environment. Select it and press Enter to quickly perform a memory test without having to burn Memtest86+ to a disc or create a bootable USB drive from it. This menu entry will boot the Memtest86+ memory-testing tool. For example, Ubuntu offers a “Memory test (Memtest86+)” option.
