How to skip the GRUB2 menu screen
I am running rhel 7.7 only, this is not a dual boot but I can't seem to get rid of the grub2 menu, the timeout is at least 0sec but It would be nice if it didn't show up at all unless I pressed a designated key. Is this possible? The redhat documentation doesn't really go through it, just how to change the timeout.
Thanks All! |
I don't know this is specific to red had, grub documents something about
Code:
GRUB_HIDDEN_TIMEOUT_QUIET=true |

Be aware, there is more to a boot menu than multi/dual booting. On the rare occasion you need to maintenance mode aka single user. Or if a kernel upgrade flubbed up, the option to fallback to a previous working on. These are a couple of common, rare examples. I set mine to console and display for 3 seconds, just in case. Someday you may learn the hard way... you wish you could get to the grub boot command line. Hope not. |

It seems you have a very different problem here. Troubleshooting: Code:

grub can have a default menu entry which can be started automatically after timeout (no need to press anything - only if you want to boot a non-default menu)

I have a desktops with 2.5" SSD boots in like under 10 seconds. You need more than hiding grub boot menu to speed things up I suspect. Difference between desktop vs mobile processors is negligible. SATA drives, size doesn't really matter... just because you're using a laptop doesn't mean it's inferior to a desktop. |

Just my note, if you'd not hide boot messages [ quite splash] you might have seen that before thinking... The boot menu is taking too long, holding up my awsome system.
Ok that's still your option. Although it's most likely a configuration thing, another option you can get from a boot menu is memtest86, if you'd install it. |
