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.
boot-repair from the USB installation media, this has worked for various problems for me in the past:
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.
