Bug à l'installation d'Ubuntu sur Asus Windows 10

[skeven]

Bonsoir, excusez moi du dérangement, j'ai essayé beaucoup de solutions proposées par le web mais aucune ne marche et je ne sais plus vers qui me tourner..

J'ai essayé d'installer Ubuntu 18.04.1 en dualBoot sur Windows 10, et tout s'est bien passé jusqu'à ce que l'ordinateur me demande de redémarrer pour finaliser l'installation d'Ubuntu. Au redémarrage j'ai eu cette image (qui s'affiche en immense je sais pas trop pourquoi mais bon au moins on voit bien) :

Que dois-je faire pour qu'Ubuntu marche sur mon pc ? Dois-je carrément refaire toute une installation ?
Merci d'avance pour vos réponses

Translated OP's post:

Good evening, excuse me from the inconvenience, I tried many solutions proposed by the web but none works and I do not know where to turn me ..

I tried to install Ubuntu 18.04.1 in dualBoot on Windows 10, and everything went well until the computer asked me to restart to complete the installation of Ubuntu. At reboot I had this image (which is displayed in huge I do not know why but at least we can see good):
What should I do for Ubuntu to work on my pc? Do I have to redo an entire installation?
Thank you in advance for your answers

What brand/model system?
What video card/chip?

Did you install in UEFI boot mode?
Is UEFI secure boot on, try it with it off.
