Hi. I’ve recently wanted to install Remix OS system on Ubuntu MATE (dual-boot), but, I need to create new entry in GRUB. Is there any Grub Customizer for MATE? 
Also, when I hit shift immediately after the startup screen, “GRUB loading” briefly appears, then I get a blank screen, and then the normal boot starts. 
Yes there is.
Grub Customizer - A graphical Grub2/BURG configuration application
How does it work these days, ok? I used it years ago on oneiric but then it got fancier and didn’t work as well, and i was short on patience. 
Grub Customizer still works to this day. I tend to install it on systems that dual boot and I’d like to edit GRUB’s configuration graphically.
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt update
sudo apt install grub-customizer
This tool can edit timeout options, appearance, modify the list of entries, and you’ll be able to (manually) add one for Remix OS (Android x86).

I like it.
I use it’s advanced functions because I like to change out my grub background frequently.
LOL, it’s nice to see folks liking to change their grub background frequently… i’m satisfied to see it work at all.
The only bad thing is you can only use 16 bit color images, so they look grainy.
