I can use Grub-Customizer to edit which options appear in the Grub menu. I was thinking of removing everything except the option to boot into Ubuntu and into Windows.
If I was to do this how could I boot into the recovery modes of these two operating systems if I needed to?
You can do so from the Grub menu.
With the menu displayed, press any key (except Enter) to halt the
countdown timer and select the Ubuntu entry with the up/down arrow
keys.
Press the E key to edit that entry's settings.
Note: Do not use Enter to move between lines.
Delete the line that looks something like set gfxpayload=$linux_gfx_mode
Go to the line that starts with linux and delete everything after ro. (In my case, that would mean to delete quiet splash vt.handoff=7.)
Now, append the following to the line (after ro): recovery nomodeset
The final line looks like this for me: linux /boot/vmlinuz-3.0.0-19-generic root=UUID=74d6aa6a-5170-4a36-b5b8-72e9c3db3989 ro recovery nomodeset
When that's done, hit CTRL-X to boot with the temporarily changed settings.
Note: Edits made to the menu in this manner are non-persistent. They remain in effect only for the current boot.
Ubuntu will now load in Recovery mode.
More info on editing the Grub menu during boot can be found here.
This is actually really simple.
