Is it safe to switch from GRUB2 to BURG?

I have Ubuntu 17.10 and Windows 10 installed in dual-boot (Non-UEFI) with GRUB2 as my default bootloader. It looks kinda old-fashioned boot-menu, I want a GUI boot-menu with a better look. I searched and found BURG as a suitable one, but I also seen warnings on the sites which say that if BURG gets corrupted, my PC would become unbootable.

Should I install the bootloader or not? Will it be safe? If not, isn't there any way to customise my GRUB2 to get a better look? I have installed GRUB Customizer but the changes I make doesn't seem to be working. Any suggestions?

UPDATE 1:

I've tried but sadly rEFInd doesn't work on my machine (or on any other machines with no UEFI OS). I've yet not tried BURG 'cause I'm not sure whether it'll work or not (moreover I have doubts that it may even corrupt the bootup configuration). Still I need help on the topic.

UPDATE 2:

Not getting any acceptable answer further, I finally decided to install BURG and test it but I can't install it. First I run this:

~$ sudo add-apt-repository ppa:n-muench/burg

PPA gets added to software sources successfully. Then I run update:

~$ sudo apt-get update

I get the following error:

...

N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Now I can't even install BURG.

UPDATE 3:

I also tried to simply theme GRUB2, but again I can't do that also. I downloaded GRUB2 themes from here. After installing I run this GRUB update command:

sudo update-grub2

And I get following error (I just can't understand what it says):

Generating grub configuration file ...
/usr/sbin/grub-probe: error: failed to get canonical path of `/boot/grub/unicode.pf2GRUB_THEME=/boot/grub/themes/Vimix/theme.txt'.
No path or device is specified.
Usage: grub-probe [OPTION...] [OPTION]... [PATH|DEVICE]
Try 'grub-probe --help' or 'grub-probe --usage' for more information.

I can't also theme GRUB2. What to do now? Any help will be greatly appreciated. Thank you.

Solution 1:

BURG is old and no longer maintained. Instead, I recommend that you use rEFInd: http://www.rodsbooks.com/refind/

It is a graphical multi-boot bootloader which is very stable and easy to customize. You can find many themes to choose from, some of which are listed in the official website linked above.

Solution 2:

Trying to use new boot-loaders but failing in which I finally gave up. After a lot of struggle, I succeeded in modifying GRUB2 to a new theme (downloaded from here) by using GRUB Customizer.

Here is what I did:

Downloaded the theme.
Installed the theme using grub-customizer [Grub Customizer > Appearance Settings > Theme > Add].
Saved the setting and updated the grub using this command:
```
~$ sudo update-grub2
```
Restarted the system and the theme got applied.

Now my boot menu looks similar to this one:

I also themed plymouth boot screen following these steps:

Installed plymouth themes using the following command:
```
~$ sudo apt-get install plymouth-theme-*
```

Changed the theme using this command:

~$ sudo update-alternatives --config default.plymouth

Then updated boot configuration using this command:
```
~$ sudo update-initramfs -u
```

Now my boot screen looks similar to the following one:

Sadly neither BURG nor rEFInd worked for me. But I'm happy 'cause atleast I was able to replace my old boot menu with these quite cool ones. Anyways, thanks to all those who tried to help me, I appreciate their efforts.
