I have a Dell XPS15 9570 laptop that came with Windows 10 preinstalled. I decided to remove Windows 10 completely and install Ubuntu 18.04.

I burnt the .iso on my USB drive. I had to change BIOS settings to make the laptop boot from it:

  1. Secure Boot > Secure Boot Enable > uncheck the Secure Boot Enable checkbox
  2. General > Boot Sequence > select Legacy External Devices
  3. Only leave USB Storage Device checkbox checked.

After those changes, the Ubuntu 18.04 installer showed up. I erased the whole disk and installed Ubuntu 18.04 on it, however upon restart I see the error message No bootable device found.

I reinstalled Ubuntu (prior to that I saw that the Ubuntu installer recognized that there's already a copy of Ubuntu installed) with two partitions, but the problems still persist.

I ran Boot-Repair, and it showed an error and this link. The error is:

grub-probe: error: cannot find a GRUB drive for /dev/sda1. Check your device.map.  
The boot files of [Ubuntu 18.04.1 LTS] are far from the start of the disk.   
Your BIOS may not detect them.   
You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk).   
This can be performed via tools such as GParted.   
Then select this partition via the [Separate /boot partition:] option of Boot-Repair. (https://help.ubuntu.com/community/BootPartition)

    It looks like you are trying to install in BIOS/Legacy boot mode to new UEFI system. Dells do need UEFI update, SSD firmware update and UEFI setting changed from RAID to AHCI for drives. https://help.ubuntu.com/community/UEFI Other 9570 threads: https://askubuntu.com/questions/1042414/trying-to-install-ubuntu-on-dell-xps-15-9570 & https://askubuntu.com/questions/1046263/dell-xps-15-9570-2018-disable-nvidia-gpu – oldfred Oct 30 '18 at 03:33

    Switching from RAID to AHCI solved my problem. Thank you for help. –  Oct 30 '18 at 04:15
