I don't know if it's just me, but on both of my installs of R10 thusfar, the grub screen is that basic black and blue grub screen.
If anyone else is experiencing this, and you'd like to have the classic wattOS background on R10...here's the simplest way that I know without having to change any configuration files. All you need to do is copy and paste an image.
1. Open your file manager as root.To open the file manager as root, you can either...
a) From the main menu, go to System Tools and click on Root File Manager. Then enter your password in the window that pops up.
...or...
b) Open your terminal, and enter the following command...
sudo pcmanfm
It will also ask for your password in the terminal after entering that command.
Either method will open your file manager as root.
Now...if you don't already have a shortcut to Filesystem Root in the side panel, click "Edit" in the tool bar, then click "Preferences". In the window that pops up, click on "Layout", and put a check mark next to "Filesystem Root". That will give you a shortcut and easy access to the root File System in your File Manager. Close the "Preferences" window.
2. Click the shortcut to Filesystem Root in the side panel, and go to /usr/share/wattOSRight-click on
green-grub.jpg and choose Copy.
3. Click the shortcut to Filesystem Root again, and go to /boot/grubOn any empty space in that folder, right-click and choose Paste
That should paste the copied picture into that folder.
4. Close the File Manager5. Open your terminal, and enter this command...sudo update-grub
When that finishes, Reboot your computer, and you should now have the wattOS grub screen.
