Good evening, I'm trying to install Haiku directly to a partition from Linux (Kubuntu 7.04), by letting the build system do the work (as mentioned by Ingo a while ago). To do this I have modified UserBuildConfig to contain: HAIKU_IMAGE_NAME = sda6 ; HAIKU_IMAGE_DIR = /dev ; and first build using jam -q haiku-image which builds everything (and let me have the ownership of the built files), but obviously fails writing to the partition. I then run sudo jam -q haiku-image which writes the data to the partition. The last output from terminal is as follows: BuildHaikuImage1 /dev/sda6 Creating image ... 100+0 poster in 100+0 poster ut 104857600 byte (105 MB) kopierade, 5,07425 sekunder, 20,7 MB/s Partition::SetTo(): active: 80 Partition::SetTo(): active: 0 Partition::SetTo(): active: 0 Partition::SetTo(): active: 0 Partition::SetTo(): active: 0 Partition::SetTo(): active: 0 Partition::SetTo(): active: 0 Partition::SetTo(): active: 0 Partition::SetTo(): active: 0 Writing boot code to "/dev/sda6" (partition offset: 58605152256 bytes) ... writing 512 bytes at offset 0 writing 348 bytes at offset 676 Populating image ... Deleting old MIME database ... Installing MIME database ... Unmounting ... ...updated 227 target(s)... It looks to me like it succeeded and that Haiku is now installed on /dev/sda6. To get an option in the boot menu, the following lines were added to GRUB: (The partition is the second partition on the extended partition) # Haiku on /dev/sda6 title Haiku rootnoverify (hd0,5) makeactive chainloader +1 But... When trying to start Haiku, GRUB just tells me "Error 12: Invalid device requested". What have I done wrong or missed? makebootable? /Fredrik Ekdahl
