Pinguy 18.04 cannot be installed on my laptop

Dears,

I hope you can help me cause I'm not a geek in Linux !


So I have a single question and I'm curious who can help me to find the solution !

History begin here : …

After some tests in Mint 19.2, I deleted Linux partition and reinstalled 19.3 Tricia without any problems and in Dual boot with Windows 10.

I tried to test different settings and per example, "PlayOnLinux ".
But this program (like the Wine project) is absolutely not working on Mint.

So I removed 19.3 cause several issues after "install / uninstall" the "PlayOnLinux / Wine" packages on the 19.3.

I checked a littlle bit with Ubuntu but same sh....
Yes ... Same issue with Ubuntu and interface of Ubuntu is not nice !

So I was looking for another distribution (a complete one / a full one) and I finally found "Pinguy".

But problem, is that I can only start this version in Live and nothing else !
In fact, when installation is complete, it's always the same disaster !
Yes ... a real disaster ! And what is this disaster ! ? GRUB !
For Pinguy installation, it's impossible to install it on my laptop ! !
Always the same bug after the installation of Pinguy 18.04 (Mini or Full)
Grub … grub … grub !!!!!!! grr

Impossible to start Pinguy if alone or Pinguy in Dual boot (if installed with Windows)

I removed the Windows 10 and I formatted the disk then, I tried again to install PG 18.04 without any other OS and still NOK ..pfff

- Laptop is a DELL 6430 ATG
- Bios compatible EFI
- Fast boot and secure boot off !

So what is the problem ???

Thanks in advance for your assistance.

Friendly yours,

Mike
