Hey!

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

Btw, I only tried with i B o o t and Empire EFI with same results. Tell me if I should try i B o o t Legacy too. Thanks

Hi, kushsolitary!

Refer to this link, that gives a comprehensive step by step on how to instal Mountain Lion on any PC: The all-in-one guide to Vanilla OS X Mountain Lion + Cham...

Good Luck, and report back - i want to know what worked for you.

P.S.: beware of misleading titles: your problem is everything but an instant reboot.

[everdone]

Major problem: arch=i386 - signifies 32 bit operation, ML is 64 bit only.

[theconnactic]

Yeah, but since the T.S. didn't mention this flag, i think perhaps it was added automatically by the bootloader he

[eep357]

Aside from the obvious issues such as using iboot, what was that about a ML DVD?

Yes I am using the ML DVD. I think this problem is specific to ML as many people are having the same problem. I will get the Lion DVD soon to test it. Apart from ###### and Empire EFi, what are my other optionS?

This bootflag  is in the screenshot from Virtual Box. I never entered it manually.

I don't have access to a mac so this method ain't for me. Anyways, thanks for the fast replies!

This seems to be a good choice. I will download it right now and btw, I just ordered a 16GB pen drive for this

Edit: Started downloading, it will take 2 days :/
I will update about my progress. Thanks again

Btw, can anyone confirm that I have AHCI already enabled by looking at the second image?

for AHCI you need see in your Bios, if your bios have this option set SATA for AHCI

As I already mentioned in my first post, there is no option for setting up AHCI in my BIOS (it's hidden by default) but I have heard that these laptops come with AHCI pre-enabled.

[kushsolitary]

Got the pen drive delivered just now and ML finished downloading. Trying it now and will report soon

Edit: upon first run, I got ApplePolicy KP which I fixed by deleting the respective Kext. After that, I got stuck at [PCi Configuration Begins] which I again fixed by using old IOPCIFamily.kext. After that, I got some USBF errors which I fixed using "USBBusFix=Yes"

But now, I am getting stucked here. I tried deleting all the ATI*.kext files and booting with "-f GraphicsEnabler=No" but still no success.

[iFIRE]

this is the mkext or the kext  from Extra/Extensions of the your USBInstaller VoodooTrackpad.kext, see if you can delete this kext and use a mouse and keyboard USB for install

Yes, I have a USB mouse and keyboard. Lemme try this

Edit: There is no "Extensions" folder in my /Extra folder. It only contains Preboot.dmg

[iFIRE]

mount prebot.dmg and you have  Extra/Extensionss

[kushsolitary]

After mounting, I found Extensions.mkext and org.Chameleon.Boot.plist. What should I do with the Extensions.mkext?

[iFIRE]

you can delete de mkext and put only two kexts, FakeSMC.kext and NULLCPUPowermanegement

[iFIRE]

backup first all graphics kexts, now delete all from S/L/E USBInstaller
