First off, I admit I am very very new to Manjaro, so I'm afraid any advice will have to be very simple for me to understand.
I have recently been trying to install the latest version of Manjaro on my new laptop, the Acer Aspire E15 -(I can give the exact model if needed). I intend to also dual-boot Windows 10 (as much as I dislike Windows) to run a couple of needed programs. However, that's another topic, and the task I am trying to accomplish is simply manually partitioning Manjaro.
My setup is this: a 256GB nvme SSD, and a 1TB HDD. I wanted to install my system, root, programs, or whatever on the SSD, leaving enough room for Windows later, then mount the HDD as my /home Manjaro folder for storing data. I assume the only way to do that is to manually partition.
However, every single way I have tried to do this has utterly failed, ending up with the dead-end "No bootable device" message from my Acer.
This is what I tried: first, a 512 MiB FAT32 partition with the mount point of
/boot/efi and bootflags 'boot' & 'esp', then a 70GB ext4 partition mounted at
/, then some swap -- all of which on the SSD. Then I formatted the HDD as ext4 and gave it the mount point of
/home. Nothing wrong, right??
However, finishing the installation and rebooting gets me the "no bootable device" thing again. Basically, I have exactly followed this tutorial and it hasn't seemed to work.
Is there something obvious I am missing here?? I know it has to be something with some sort of boot file missing or something, but I'm really clueless, since I have almost zero knowledge in this area.
Any advice on how to fix this, or a proper (better than what I've done) way to manually partition would be HUGELY appreciated.
