I have an SSD with Windows 10 on it, a HDD to go along with it with just data, and now an SSD with elementary OS on it. During the installation i had some problems, so unplugged the SSD of Windows 10, and HDD's SATA cables, and the installation ended up correct. Now if I start the PC I don't get the GRUB screen, but the elementary OS login screen instead. I tried to edit the grub config, and update it manually, but that did not help. How could i manage the dual boot?

I tried to edit the grub config
We don't know what you did configuring grub so maybe you did the following
By default Grub comes hidden
to change that just edit
$ nano /etc/default/grub
Change where it says
GRUB_TIMEOUT_STYLE=hidden
,to
GRUB_TIMEOUT_STYLE=menu
Now update grub
$ sudo update-grub
Reboot to test
You can adjust the timeout in seconds there too.... check the manual
https://www.gnu.org/software/grub/manual/grub/html_node/Simple-configuration.html
Also there's a way to access the Grub menu without editing
Just after the Bios/UEFI post, press SHIFT repeatedly. If you fail the timing, reboot and try again.
Try running boot-repair
from the USB installation media, this has worked for various problems for me in the past:
https://launchpad.net/~yannubuntu/+archive/ubuntu/boot-repair.
sudo apt install software-properties-common
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt update
sudo apt install boot-repair
This should automatically detect your Windows 10 partitions.

Unfortunatelly it did not solve the issue, after a reboot it prompted me for the encryption key again, instead of the GRUB menu. Does this mean i have to do a clean reinstall?– DanielDec 16, 2018 at 22:00

@Daniel may as well, if you haven't customised too much. But this time perhaps note exactly what problems you get with the SSD plugged in and edit your question. Dec 16, 2018 at 22:04
