Congrats. With all these steps you have done, take some notes and save them because you will forget soon.

Emperor How can I make the bootloader check that there is a Windows and give me choice to boot it?

Try to update grup: $ sudo update-grub

If it fails, try to mount the Windows partition where the system is installed just by opening it with File Manager and then do again
$ sudo update-grub

      Playing with fstab is dangerous because the system may go to emergency mode, not sure what happens with the data.
      Of course you can remove what you did add to fstad with $ sudo nano /etc/fstab and then reboot.

        algent So I have to type the $ before the command? I found that command and tried to use it but it wanted me some sudo password...which to begin with is hard to write and it's not my password.

            [deleted] Wow...why it just doesn't save this setting automatically?
            Never heard of boostnote-I will definitely check it out 🙂

              boostnote is more complex and seems like it's geared towards developers and code-writers.
              Joplin is more private, local, and FOSS alternative to Evernote-it's simple to use and it has web-clipper-it can handle large ammount of bulky notes and organize them.
              So my best bet is to search for snap...

              [deleted] Gnome disks is where I found that I can mount them-so even from there it didn't save the changes.

                [deleted] I figured that there must be additional settings and managed to do that 🙂
                But this terminal commands always require some password and I just can't type-I begin to write it and I can't-the only thing I can do is press enter and abort the command-I experienced such problems in various Linux distros on VMs...so this is from the stupid linux-y things...
                I remember I could do something about it, but what is it?
                Update: If it is truly that it's for security reasons and you have to just type the password then the command is not working-I write the command...then write the password and enter-there was no text informing what happened or whatever-I am just on new line to type other commands.

                    dbarron Well it is absolutely possible, but I am still booting automatically in Solus, instead of W10. I have no options to choose from when booting. What should I do next?

                      sudo clr-boot-manager set-timeout 5

                      See if that helps you (reboot after successful) and watch closely (5 seconds isn't long) 🙂

                      That's odd. You should have got a 5 second window to choose which bootloader (text screen).

                        dbarron So there is something wrong either with the command or again with fucking HDDs, formats and so on.
                        Let me give you a bunch of information-maybe some of it will be valuable:
                        I was with W7 and used the free update to W10-as we've seen W10 is on MBR HDD.
                        Later I added the second HDD-2TB...after long issues it's now where the bootloader of Solus is and it's GPT HDD.
                        So is there a problem, because;
                        1) The 2 bootloders are on different HDDs.
                        2) The different HDDs are differently formated-one is GPT and the other MBR.
                        3) Even the format of bootloaders are different-Solus is on FAT32, while W10 on NTFS.

                          Yeah, I think you're only suppossed to have one bootloader. Just multiple entries in the EFI.

                            dbarron So the question remains-what do I do xD
                            Simply deleting W10 bootloader will result in unabillity of booting in in my opinion. Because I can't display both OS with 2 bootloaders, I probably would't with just one 🙂
                            Or I should delete it and then run the sudo commands, but what if it fails?!

                              What you needed to do was install the bootloader from solus on the same disk and partition as the Windows one was using, so they live together. Otherwise (as you stand now), you have to choose the proper disks as boot device every time you want to change which boots.
                              I can't really tell you how to do this, because I never really retain these things. I just do them (and I'm visually oriented..I have to do/see it).
