Thank you in advance for any advice that anyone can give me to get my system booting.
Ok so, after partitioning the main hd and installing OSX to it (along side my bootable Windows 7 installation) whenever I try to boot up OSX it almost immediately hard resets the computer. When OSX was installed by itself without 7 I experienced the same issue. Installation was painless but as noted I can't get into the OS. Not sure what information to give anyone aside from hardware specs (located below). If anyone can help me or needs more information in order to help me please let me know and I will do what I must to assist. If required I can create an Everest Report of all hardware inside this machine and upload it.
