Osmolar Posted January 20, 2009 Share Posted January 20, 2009 I've run into some trouble after installing Windows XP on my desktop... My PC has two SATA drives, on one of which I installed Leopard 10.5.6. using a GUID partition. After getting it tweaked and running perfectly, I decided to install Windows XP on my remaining drive. I powered down and unplugged the OSX SATA drive and proceeded to install Windows to the other drive without a hitch. XP boots normally and runs well. I then plugged my OSX SATA drive back in and rebooted. Tapping F12 at boot allows me to select which disk from which I would like to boot. Unfortunately, selecting the OSX disk results in a hang right after the POST/BIOS screens finish. I never even see the Chameleon bootloader start. Correct me if I am mistaken, but I thought by powering off the OSX SATA disk I would avoid the XP installation from altering the OSX boot record...? I've run the Gparted Live disk and both the EFI and OSX partitions on the OSX SATA disk are flagged as BOOT. Any ideas on getting OSX boot functionality returned? Many thanks in advance!

Boot OSX from DVD and install Chamaleon or efi bootloader from UInstaller: http://######.com/downloads/UInstaller_1.2.zip Giorgio Link to comment https://www.insanelymac.com/forum/topic/148076-lost-ability-to-boot-osx/#findComment-1048466 Share on other sites More sharing options...
Osmolar Posted January 20, 2009 Author Share Posted January 20, 2009 Thanks for the quick reply, Georgio... I hate to be a bother, but would it be possible for you to be more specific? When I boot from the Kalyway install disk, I am not given an option to boot from the OSX installation hard drive, only the DVD. Is there something I am missing here? Thanks!

Guest Posted January 20, 2009 Share Posted January 20, 2009 Try iDeneb 1.3 DVD After the countdown, should appear the choice to boot from HD.

Osmolar Posted January 20, 2009 Author Share Posted January 20, 2009 Well, I downloaded, burned, and booted with the iDeneb 10.5.5 DVD, but I am still not offered the option to boot from the OSX SATA drive. Any idea what could have possibly happened to my OSX install? Gparted shows both partitions flagged as boot and Windows XP sees the drive as a GPT protected partition. I'm stumped. If I reinstall Kalyway or iDeneb to the secondary SATA drive is there any possibility of recovering? I had OSX running so well, I'd hate to lose it all now. FYI, the OSX install was using the retail Leopard DVD from my original Kalyway install on the secondary SATA drive.... dunno if this matters or not. Thanks.

Maniac10 Posted January 20, 2009 Share Posted January 20, 2009 You may try booting ideneb dvd and telling where to look using: rd=diskXsY where X is you disk number (0 for first, 1 for second...) where Y is your partition number (0 for first, 1 for second...) Once you´re in just install chameleon and it should be fine.

Osmolar Posted January 20, 2009 Author Share Posted January 20, 2009 Thanks for the reply... Do I boot from the EFI partition or the installation one?
