Yes you're right.
Sorry for the idiotic problem I posted here, I formatted the USB and made it bootable again, downloaded the files again, and while making the grub configuration file
it hit me, previously I made a
.txt file named
grub.cfg, so that would be
grub.cfg.txt which is a text file, not configuration.
I was able to live boot with no problems, tested my network cards
all good, played around with it a little, but I didn't install, it wasn't my intention in the first place, since all the problems I might face + I don't really need it installed, I'm just seeing what I can do with the distro and its tools.
So thank you again for the tutorial, and thanks for the help
