Just comes up with more complex grub???

[Well-Hi]

i managed to hit enter before i could say the issue sorry, this is all very new to me, but after i set everything up through terminal and did a reboot, all that came up was a text based grub where you had to type commands? is this normal? im not sure if ive done something spectacularly wrong or if its just a simple fix but its annoying i would appreciate help :'))

Nope that is not expected, did you do something else besides the installation of this theme?
You can uninstall the theme's scripts as indicated in the readme. If you cannot boot you might need a livecd to be able to boot first.
