I did what you said but I still wasn't able to get the menu.

But please, take a look at my script (posted a few messages above): after the make_timeout function declaration there's the block you made me add (now updated to the latest version you suggested), but a few lines down, 12 to be precise, BANG! those lines were already there! And unfortunately didn't work...
The reason it appears twice is the second is within a conditional (regarding GRUB_HIDDEN_TIMEOUT_QUIET). So we are manually forcing the timeout check into the final product, but it also may appear if conditions are met later on. By placing it at the start of the section you guarantee it's going to be in the final product (even if it may appear twice under certain conditions). Since you are forcing it to appear in the final product under any conditions, you could remove it from the conditional section, but I'd rather not.

We'll give this one more shot and if it doesn't work I'll tell you how I set it up a bit differently. I'd rather get it working this way first.

Finding mistakes in scripts can be difficult to do, especially if they have been modified multiple times. Rather, rename your current file, remove the executable bit, and then save the attached file as your /etc/grub.d/30_os-prober file. Make it executable, then update grub. I've placed the timeout check at the end of the file.

Code:
sudo cp /etc/grub.d/30_os-prober /etc/grub.d/30_os-prober.old
sudo chmod -x /etc/grub.d/30_os-prober.old
Copy the entire contents below into /etc/grub.d/30_os-prober, save the file, then
Code:
sudo chmod +x /etc/grub.d/30_os-prober
sudo update-grub
Here is the entire Grub 1.99 script
Code:
#! /bin/sh
set -e

# grub-mkconfig helper script.
