I just tried to install Mountain Lion on my Vaio VPCEB46FG but when I inserted the ML DVD (after loading i B o o t) and pressed enter, I saw the apple logo for a few milliseconds and then the laptop rebooted. I also tried PCIRootUID=1 flag with -x but then it gets stuck on the apple logo (no loading animation, just the apple logo).
This is the image of the apple logo my laptop gets stuck at
I don't have any option in my BIOS for enabling AHCI but I am pretty sure it's already enabled. Check the image below:
I tried with -v -x flags and as it got rebooted again, I made a video for you guys to see the errors. Here's the video
and here's the same screen (without ATI info) in Virtual Box. Yes, the same reboot thing happens in virtual box too!
I think this information will be enough to track down the error. Oh, and here's my config
- Intel Core i5 480M
- 4GB DDR3 RAM
- 500GB Hard disk
- ATI Mobility Radeon 5650HD
