After having bug 888 solved, I ran into a problem with Grub2.
I’d like my laptop to do dual-boot.
Because I know osprober does not recognize the Win10 installation, I have Grub installed on the 2nd HD.
When I point the BIOS to start from there (Using F9 - Change Boot order), GRUB either hangs in printing ‘GRUB’ repeatedly or GRUB just shows ‘GRUB’ and the laptop immedialty reboots (and goes to default UEFI boot: Windows 10).
I’d like (either or all)
1: osprober to find my Windows 10 installation (at /dev/nvme0n1p1)
2: GRUB2 to show the list of OS-es installed and be able to start those (at least Antergos at /dev/nvme0n1p6 or via /dev/sda4)
If Windows could be probed, I might feel confident enough to replace the bootloader on /dev/nvme0n1.
I’d like to install as free as possible with my partitions, so just a root (/) and a SWAP partition.
Mounted 2 data partitions from sda (sda1 & sda3) to /media subfolders
I tried with and without separate /boot partitions.
I tried different flags on the partition (using gparted)
And just to be sure the boot folder (or partition, whatever setup I was trying) did not miss anything, I did a complete reinstall of everything.
How should I proceed?
What am I doing wrong?
