Hi, if I remember correctly the result of the issue showed up in 2 places 1) there is a script called ofboot.b which is a script for Open Firmware. Bootloader that loads before yaboot. The problem was already in this script. So what I initially did was booting rescue cd and mounting /dev/sda2 (this is where boot partition with yaboot is) and modifying ofboot.b Then I got yaboot and then tried to find the right path in yaboot. At the end it turned out to be wrongly generated openfirmware path. Perhaps I should create a fix for ofpath script coming with yaboot 1.3.16 which comes as default with Ubuntu. I just hoped 1.3.17 would resolve the issue by itself but it did not. So I stayed with 1.3.17 for my machine. regards, Matevz > On 27. apr. 2016, at 20:29, ArminiusTux wrote: > > Hi there, > > thank you for responding so quickly and (apparently) hitting the nail. > Would you agree that modifiying the partition target path in the yaboot.conf file should be enough? > > > I will try to revive the linux only partition on the mac SSD as yaboot comes up there. > > > But before repartitioning the boot loader was not coming up at all when there also was a apple partition (MacOS X Leopard) on the SDD. > Have you also got experience on dual boot OS situations on PowerMacs? > > > Kind regards, > > John > > > --- Ursprüngliche Nachricht --- > Von: > > An: > > Betreff: [Bug 1575394] Re: Yaboot fails to load Ubuntu (MATE & Lubuntu) 16.04 LTS > >> Hi, >> >> I have seen the same issue on PowerMac G5 2.5 Quad PowerMac11,2 >> >> The problem is in ofpath script.
