How can I install Linux Lite by the very beginning?

[Moltke]

Then there is not point to me to send here a screenshot of my BIOS configuration or the model of my PC.

You're wrong, yet again. Of course there is not only 1 point but several ones into asking those details, 1, we're not in front of your pc but you and you are new to Linux so you might be doing something wong without even know it and 2, since we're not "on site" but only you, we can not know if there's some configuration setting that needs to be done.

I did NOT boot into Linux Lite. There was a question if the problem was the BIOS that can not do boot from a USB driver or if the problem is anything else. In order to answer that question, I used an other old pendrive USB bootable (with windows boot for example) just to check if the BIOS is able to do boot from an USB device as I configured it for.  The BIOS did successfully boot from a USB device, so it´s a proof that my BIOS is correct configured to do that and the problem is anything else than BIOS configuration.

This only proves that you've no idea what you're doing. Did you try booting Linux Lite from that "old pendrive" which did boot  "windows for example"? Did you try the same "windows for example" in the not "so old pendrive" you've been failing to boot Linux Lite from too? Acording to your own account, "you've succesfully booted "windows for example" from an "old pendrive" but failed to boot Linux Lite from a not "so old pendrive" which begs the question, is one of those, either the old one or the not so old one, working correctly? which one is?  Again, according to your own words, looks like something might be wrong with the "not so old pendrive" and that the "old one" does work properly, so why don't try booting Linux Lite from the "old pendrive" and see it that works?

I don´t know if I did it right, but I did that following steps considering we don´t have manual for that:


STEP 1: Download ISO using the link from oficial LinuxLite website. ->  Status OK. Done!!

STEP 2: I used Rufos software in order to create a bootable USB device.  -> Status OK. Done!

STEP 3: I used "Universal-USB-Installer-1.9.9.0" software to extract the ISO file into the USB device. ->  Status OK. Done!

STEP 4: I configured the BIOS to do boot from an USB device before start Windows 10 boot.  -> Status OK. Done!

STEP 5: Boot into Linux Lite from the USB device and click on the icon "install" to start deploying Linux Lite. -> FAIL !!!

If you did follow those steps is no wonder your Linux Lite Live USB won't boot, again, if the above is correct, then you've made at least one mistake; step 3 isn't needed. Try again like this:

STEP 1: Download ISO using the link from oficial LinuxLite website.

STEP 2: Use Rufus to create a bootable USB device.

STEP 3: Configure the BIOS to boot from the USB device.

STEP 4: Boot into Linux Lite from the USB device and click on the icon "Install Linux Lite" to start deploying Linux Lite.

Again, this STEP 3: I used "Universal-USB-Installer-1.9.9.0" software to extract the ISO file into the USB device. ->  Status OK. Done! if you actually did that after using Rufus to burn the iso into the USB, then you destroyed what you did in step two, making the USB unbootable and that's why your bios can't boot Linux Lite, there's no need for this "step 3", try again following the 4 steps I pointed above.

Hpe this helps!
