Can't boot from Mountain Lion 10.8 bootable USB

Hi guys...

My friend is in big trouble, he has macbook (Late 2006) with 1.83 core 2 duo processor and mac os x 10.5 was installed at the time of purchase.

Due to some problems, he formatted his hard drive and installed windows 7 on it, now he has only windows 7 on his macbook.

Now he want to install Mountain Lion 10.8 back (he don't have installation disk which comes with macbook). so i downloaded mountain lion 10.8 from web which is almost 4.1 GB.

Here is the procedure i followed to create a bootable stick.


I formatted my Kingston 16 GB USB using Disk Utility with Mac OS Extended (Journaled).

Then partitioned it with these configs.
Volume Scheme:1
Format: Mac OS Extended (Journeled)
Options= selected GUID Partion Table

Then in restore tab, i selected source as downloaded file named as InstallEDS.dmg (about 4.1gb) and dragged Usb in destination. then pressed restore.

When i restated macbook and pressed option key (ALT) to load boot menu. It does not show usb, it only shows windows option.

So please help me to solve it, anything wrong i did or if i missed anything.

I want to install Mountain Lion 10.8 from USB Stick.
 
Does the OS X 10.8 Mountain Lion USB flash memory thumb drive show up on your Mac in System Preferences > Startup Disk*?

That I do not know.
Your friend could always spend 19 USD and get the Mac OS X 10.6 Snow Leopard Upgrade DVD from the Apple Online Store if the USB method will not work due to the lack of another Mac.

But know, that either OS installation will require a clean install, thus erasing every volume / partition on the HDD and creating a new volume, thus Windows 7 will be lost, unless it gets backed up first.

Yes i want to install MAC only, and windows 7 is of no importance.

Well i am currently doing the process again, thats why i can't confirm whether it shows in disk utility or not, as soon the process ends i will check it and tell u.

thanks anyways.

It won't run, as I said in my last post your maximum (Officially) is Lion 10.7.4.

But look here:

[GUIDE] SUCCESS! Install 10.8 on OLD unsupported Mac

Edit: But, it won't run 100% on your Macbook----- MacBooks with GMA 950 > Works, no QE/CI

So, don't waste your time.

Your Max. is 10.7.4, up to you what you want to install, but do know that Lion is kinda buggy, it comes with more features though than Snow Leopard, but SL is more stable.

Mate what if I want to create a bootable USB of mountain lion if my mac was shipped directly with it? (IE I do not have the installer in the app store as I have never purchased separately)... I have tried searching for it but no success

Thanks and Regards

From the silent on this tread I have to assume that is not possible... right?

Yes, it can be done. You need to grab the 4.7GB installer from Apple's servers using this process. Then use this free utility with an 8GB USB key to make your installer.
 
Thanks mate, not sure if I am that gutsy to follow that process and risk to screw my install, maybe sparing the 20 buck ML costs on the App Store is more appealing at the moment.
 
maybe I need to read it again with the fresh mind of the morning as yesterday I have had a very busy day at work and I come home with my head wreaked.

Will update you if something is not clear.

Thanks for the support!

Then it is bootable, as it does show up in Startup Disk after all. The icon just represents it as ejectable USB flash storage thumb drive.

But it still won't appear when I hold down the option key, to choose the bootup disc.
It just shows the regular boot up and the recovery 10.8 one..
