Before anything else, I'm not sure about the specification, model, wherever of this PC, according to the papers that are coming with the PC it is an Inspiron 15 3000 but there are others documents saying this is an Inspiron 3583 -- is it there any command that can help here in order to be sure ...?.
I was able to boot the live/USB it was less difficult, the information at the screen in this BIO it is much clear to me, i just disable the 'boot for windows' option and put the USB to boot.
After that i just needed to disable secure boot, exit, restart and it boots.
It can recognize the Networks. Of course, this time i'm connected by cable.
Everything looks ok, but i'm not going to do anything for the instalation since i have some doubts ... i'm writing at this moment from the Dell in the live USB/Manjaro.
The tool that i use for partition, etc, is PartedMagic but for some reason it do not boot now ...
Can i do everything from here, means, from this Live/USB/Manjaro with the Gparted?.
Thank you for any comment and help in advance!.
