Hello,
I'm new on the forum and new Ubuntu user.
Since I installed version 20, I only have startup problems. Indeed, I have to boot several times (3, 5 or 7 times) to finally appear a menu and only allow me to start in Rescue mode.
I reinstalled ubuntu 3 times and each time it's the same...
You will find below the link to the boot-repair application report

and my configuration below
Unbuntu
Version 20.10 (Groovy Gorilla) 64bit
noyau Linux 5.8.0.25-generic x86_64
MATE 1.24.0
Matériel
Mémoire : 1,8 GiB
Processeur : Intel® Celeron(R) CPU N3150 @ 1.60GHz × 4

In advance, thank you for your help
