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




Now update grub

$ sudo update-grub

Reboot to test

You can adjust the timeout in seconds there too.... check the manual


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?

  • @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.
