Good to hear.
Regarding your ‘unable to boot from disk’. I have experienced this. In my case, I did not read the UEFI Booting instructions properly and I missed this the below step (which is in the installer and not in the Drive setup). If it is missed, it wont boot on the drive Haiku was installed on.
Install the boot software into the EFIBOOT partition.
-
Close Drive Setup, and hover over the Tools > Install EFI loader option.
-
Select the partition you created in step 3.
