Gianfrix Posted March 16, 2008 Share Posted March 16, 2008 Hi! As I wrote on the title I installed Mac OS Tiger (the ISO was called MacOS 10.4.8_JaS support AMD_Intel_SSE2_SSE3_with_PPF1.iso if i'm not wrong). The problem is that, after the installation, the OS does not boot! After my PC loads the BIOS, so when it tries to boot from the HD my PC "freezes". It's like there isn't any bootloader... what can I do? Thanks in advance.

Gianfrix Posted March 16, 2008 Author Share Posted March 16, 2008 UPDATE: I was able to boot with the DVD (using this boot commandline: mach_kernel rd=disk0s2). Can someone can help me to make me boot without using the DVD?

MiJKa Posted March 21, 2008 Share Posted March 21, 2008 Apparently, you are not alone in this. I also had the same problem, with one of the JaS 10.4.8 versions. Reading around for a few days, I finally ran across someone who'd tried something that hadn't even crossed my mind. (Wish I could remember who, to credit properly, but oh well.) Apparently, for some reason, your hdd forgets that the partition sporting tiger is active. (This sounded ...strange to me. I had made it active, I should have been able to boot. I was not able to though, was desperate and decided to try setting it to active again.) So, I mashed on the F8 key, as I was booting and selected the -s boot flag, to enter single user mode off the DVD. This lead to my being able to use the fdisk command to set my Leopard Partition active and boot from the HDD. The following should work: fdisk -e /dev/rdisk0 update write exit reboot should that prove fruitless, there's always: fdisk -e /dev/rdisk0 reinit flag 1 write exit reboot --------------------- /dev/rdisk0 <-- represents the hdd you have OSX installed on. rdisk0 should be your first drive, rdisk1 your second, etc. flag 1 <-- represents an (active) flag to be set to the FIRST partition on the disk you're working on. (I've here assumed your OSX installation was on the first parition of the first HDD in your system.) --------------------- Be forewarned, my MBR was still kinda buggy but I was able to boot from my HDD after fixing this up.
