UPDATE: After the first boot using GPT and installing bootman, it appeared as if bootman had deleted the GUID partition table. The boot menu was there but no partitions were found. I booted into a Haiku USB key, and the drive appeared to be blank in DriveSetup, as in fresh from the factory with no partitions. A couple boots from the USB key later, I noticed the partitions on the SSD had reappeared and that I could indeed use the boot menu to boot the partition of my choice. This is a rather peculiar behavior.
I’m trying to use DriveSetup to partition an SSD. I would use GPT, but BootManager doesn’t seem to play nice with the partition table. The option to use Intel extended partitions is greyed out. Otherwise it would be my preference to extended partitions. Is my best bet to use something like gparted? I’d love to do this within Haiku. My main requirements are having more than 4 partitions and to use BootManager as my boot menu.
