Why does grub show up like this in the BIOS?

Dualbooting windows and ubuntu (ubuntu is mostly working) and as in the picture, grub shows up in the boot order list as a bunch of gibberish.

Why is this? Could it hint at something wrong? How can I fix it even if just to make it look nicer?

I did have to restart the installation a bunch. Including once because it failed to create the partition, but the installation completed once that was done.

EDIT: I reinstalled grub and this persists so Im still curious.
