I i just bought a new dynabook with windows 10 installed on it. I achieved to install Ubuntu 19 alongside windows 10, but after it it's impossible to boot into ubuntu. I tried changing in the bios were ubuntu appears in the boot order, but it keeps booting into windows. I've also executed the bcdedit command in windows and still grub is not appearing. Any help would be appreciated, maybe it's already solved this problem, but i didn't find a solution yet :(

Edit based on additional information provided as answer:

I'm attaching here some screenshots asked above for further help.

My computer is a Dynabook Tecra X40-F-140.

I also notice that list partition is not detecting Ubuntu's partition. I created a 600 GB partition and a 1 GB swap space in the missing space (it is a 1TB HDD), the partitions created would be between partition 3 and partition 4.

Boot options:

Current HDD boot options:

list partition output:

Thanks in advance!

Note: If after installing Ubuntu, you boot directly in Windows, check in UEFI settings for changing the boot order. If you see no option to set the boot to Ubuntu, you need to fix it from within Windows. When you are in Windows desktop, hover the mouse in left corner, right click and select administrator’s command prompt. Then run the following command:

bcdedit /set "{bootmgr}" path \EFI\ubuntu\grubx64.efi

This should make the Grub default and hence you can access both Ubuntu and Windows from it.
