it is the first time I'm trying to install Linux on my Dell G3 that I have 3 months ago. Well, when I bought it already come with a Linux (16.04 LTS) but in a HDD. I have made a little upgrade installing a SSD on it. Well, my first choice was trying install Ubuntu with no dualboot. I'v installed linux sucessfully, but when I try to start the system my PC didn't recognize as a boot option, so appears a message saying "No bootable device found". I have tried it with 16.04, 18.04 and last realease (19.04). All of them occured the same thing. After some guides in the internet, which includes:
- https://www.todoespacoonline.com/w/2015/05/instalar-ubuntu-e-windows-em-dual-boot-guia-definitivo/,
- https://www.google.com/amp/s/www.dionysopoulos.me/portable-ubuntu-on-usb-hdd/amp/
- Installation of Ubuntu 16.04 from a USB drive freezes
- "grub-install /dev/sda failed" for dual-boot with Windows 10

I still getting the same error. I trying now make a dualboot. Please, help me install Ubuntu on my PC. What I'm doing wrong?
If you guys need anything, let me know. I'm really new on installing Linux.
