I recently buy a dell inspiron 3480, in which ubuntu 18.04 lts was installed by default. Then I installed windows 10 “sucesfully”. But after a while, I had an issue with 100% disck usage by windows process, So I decided to go back to ubuntu. However, I am having trouble with the installation of ubuntu, founding this info https://certification.ubuntu.com/hardware/201810-26530, in which you can find that “Standard images of Ubuntu may not work at all on the system or may not work well”.

I installed ubuntu normally from usb, but now, the computer does not boot at all.

My final objective is to make a dual boot in this laptop. Any advices on this issue? Thanks in advance.

Update: in this link I store some pictures of the bios setup of my laptop: https://github.com/nmolanog/dell_3480_bios

The error message is : "No boot device found".

I am pretty confused since the boot options are not as simple as I used to. There are several options for this. I hope some one expert could check the settings and help me out a bit to get the appropriate settings to run ubuntu.

What is the message you receive when your computer doesn't boot? Do you know if you installed GRUB as your bootloader, or are you letting Windows handle it. GRUB will automatically configure a dual boot Ubuntu and Windows configuration. If your problem is that GRUB isn't working, you can try rebuilding it by dropping into a root terminal and using the update-grub command.

You can find out how to gain access to root terminal on an installation that doesn't boot here.

How do I boot into a root shell?

I hope this helps.

I suggest to switch from UEFI to legacy in BIOS and try to do a clean install.

How are you? I discovery a way to format without this errors.

This error it's due the pendrive bootable not support the UEFI boot.

I did a new bootable pendrive, now supporting the UEFI boot and work's correctly finally.

I used Yumi multiboot UEFI mode, Download the option Yumi UEFI Download, make new pendrive bootable and the next steps are the same.

Also, a friend used the Startup Disk to generate a bootable pendrive in linux, this worked fine too.
