This might be a duplicate, but it's been several months and on this system the grub screen is never visible when it boots up and I hold the Shift key. Booting does work, the screen is just not visible. The graphics card on this system is an intel internal NVIDIA GPU GeForce 7025 / nForce 630a (C61). I thought that it was glitch that would disappear over time, but it's been months now and this bug persists.
