Sotirios Papakonstantinou Posted December 7, 2014 Share Posted December 7, 2014 Hello! Sorry if this has been already asked, but I didn't find something similar with a quick search... Little background first: I had an old 120GB hard disk which I had formatted as MBR and had two MacOS partitions. In the first I had Mountain Lion 10.8.4 installed, and at the second Leopard 10.5.2, as a backup in case something goes wrong with the Mountain Lion , to be able to boot into Leopard and fix it. Yesterday I decided to download and try Yosemite 10.10.1 (latest). I used SuperDuper to clone Mountain Lion from the first partition to the second (I didn't wanted to do a clean installation and have to reinstall everything). Then I downloaded Yosemite from Apple Store and tried to upgrade the second partition. I got the error message that I should reformat the disk to GPT! No way I was going to lose all my data and didn't had a spare disk to install there. So I used a utility to create a bootable USB Flash with the Yosemite installer and then patched the appropriate files to allow installation/upgrade to MBR disks. I then had to boot the USB Flash with GraphicsEnabler=Yes and -v options since after detecting my card (nVidia Geforce GT 620) I lost display (out of sync). So far so good, I upgraded the second Mountain Lion installation to Yosemite 10.10.1 My problem: I installed latest Clover, but I got a Boot0=OK, Boot1=error message, so I installed latest Chameleon with GUI. From Chameleon I can only boot to Mountain Lion (first partition), when trying to boot to Yosemite (second partition) I get an error message such as "kernel no found". I can only boot to Yosemite using the USB Flash installer. I tried to copy a kernel file to System/Library/Kernels and some other files, but I screwed Yosemite, so I now try the upgrade/repair from the USB, otherwise I will have to clone Mountain Lion with SuperDuper again and redo the upgrade. Any ideas? Any setting/configuration in Chameleon I am missing? Another minor problem was that my network card (Realtek RTL8111F Gigabit LAN, onboard) was supposedly connected to the router, but couldn't connect to the Internet. But this should fix as long as I install latest OEM drivers from www.realtek.com Thank you in advance My specs: Asus P8H61 m/b (Intel H61 chipset) Intel Core-i3 3220 3GHz nVidia Geforce GT 620 8GB DDR3 1600MHz RAM SoundBlaster Audigy and Realter HD audio Realtek RTL8111F Gigabit LAN etc Link to comment Share on other sites More sharing options...

I suppose this is done by editing a file in terminal. Can you please guide me as I am not very familiar with it? Link to comment Share on other sites More sharing options...
