Trying to do same partition setup as with fedora:
GPT
8mb bios-grub btrfs for root / and ext4 for /home. Problem is it doesn’t boot. I’ve had this problem on all arch derivatives. Tried in virt manager, vmware etc same result. Is there a partition or something else I’m missing that is causing it not to boot?
Do you have a EFI-Partition? Maybe your 8mb bios-grub is to small.
Please post result of inxi -p and lsblk.
This is on a VM, KVM/Virt manager
inxi -p:

hmm i saw this on telegram 
and seems there is a BUG related to legacy grub gpt and BTRFS
If i choose BTRFS i have the same .. and arch-chroot to simply reinstall grub does make system booting .. https://0x0.st/Kq8X.txt
seems it does not run grub-install properly?
@dalto
WARNING: [PYTHON JOB]: "Non-EFI system, and no bootloader is set."
Didn’t we have this issue a while back and it was fixed by something?
I managed to get it to install successfully. Only difference was setting “/” to 20 GB. everything else was the same, home and bios_grub partitions
Why would increasing the root partition size, i.e. /, from about 10 GB to 20GB result in success? That does not make sense. Is it since you do not have a separate /boot and a efi partition. What is the size of the linux kernel images and initramfs? Did you install the headers and symbols too? How many Linux kernels do you have?
After looking at your data above this would have been my advice to enlarge your disc space.
Glad you got it working!
