I just bought my laptop with windows 10 on it, and two disk an SSD and HDD. Windows 10 is already installed on SSD. I partitioned HDD into 3 partitions and one of the partitions I installed ubuntu from USB and the "something else" option instead of install alongside windows. The partion with ubuntu is using ext4 file system.

The problem is that when I restart the computer I don't see the option to select ubuntu. Windows 10 is booting automatically.

So far this is the best answer I got but the problem is that I can only desable secure mode if I switch the boot mode from UEFI to LEGACY mode. However when I switch to legacy mode windows boot manager is disable, and when I boot, I get

No boot device found error.

How do I see the OS selection after booting? because basically ubuntu is surelly installed on the partition I want it to but I don't get why there is option to select the operating system.

Check your boot order, I think "Windows boot loader" (or something alike) is on top so grub wont load.

Set grub as the first boot option and you will boot into grub, where you will have the option to choose either windows or Ubuntu.

If grub isnt in the list you probably have to add it manually via one of the options in your BIOS or by disabling secure boot and install ubuntu again.
