helob Posted July 16, 2012 Share Posted July 16, 2012 I tried by mounting Mountain Lion_GM.dmg in Lion and run the installer. Installation went smoothly but on reboot, it still show Lion. Not trace of ML at all. Would appreciate if you can share with us the steps you took to install ML over Lion.

johncool Posted July 16, 2012 Share Posted July 16, 2012 You have to create a USB disk installer as maly70 said. Follow one of the guides available on the forum to do such a thing, or check http://myhack.sojugarden.com/. Only after you've done this and booted from the USB installer can you upgrade from Lion to ML.

Yes im new to osx and yes im needing help and yes thats why I posted on a forum to ask. Facepalm back at you!

nyolc8 Posted July 18, 2012 Share Posted July 18, 2012 tsddave: I already answered to you... It doesn't matter where did you got Lion or where did you got ML. The install method is the same.

invisiblesurfer Posted July 25, 2012 Share Posted July 25, 2012 You just start the ML installer and install it onto Lion without formating... and done. nyolc8 - one question from my end: In order to upgrade to ML (rathen than install from scratch) do you need to upgrade via the in-OSX app or by the usb image?

tsddave Posted July 25, 2012 Share Posted July 25, 2012 I tried using the OSX app to upgrade my Lion to ML Golden master from the desktop. I did an install process and restarted my computer but nothing changed. I havent tried usb method because im concerned that it will wipe out my install of lion and I dont want to lose everything.

Crabhunter Posted July 25, 2012 Share Posted July 25, 2012 Have you considered a second hard drive? they're not that expensive and you can get used to ML, gradually install all your apps and settings and when you're happy format the original drive and use for data.

tsddave Posted July 25, 2012 Share Posted July 25, 2012 Sadly thats out of the question for me, ive already maxed out the slots for hard drives on my pc. Having OSX Lion on one, Windows 7 on another and various storage drives. I see the Apple store is selling this as of today so im thinking just buy it and hope it installs from the desktop. I dont really understand why some can install from desktop and others cant.

nyolc8 Posted July 25, 2012 Share Posted July 25, 2012 On PCs, the desktop-install app simply not working. On PC, you can only update with booting into installer media, then install osx onto Lion partition without formating.

On PC, you can only update with booting into installer media, then install osx onto Lion partition without formating. This is not entirely true. If you are using a DUET EFI bases bootlader such as Clover or XPC, they reboot after the preparation stage of the app (from MAS) and continue with the installation routine like on real Apple hardware ....

EnzoFX Posted July 26, 2012 Share Posted July 26, 2012 I believe simply running the app doesn't work because that assumes you create a 8GB partition where it copies itself to, in order to resume the install after restarting? This is how real Macs do it. I could be wrong, but I remember Lion upgrades neeeding an 8gb partition on your HDD. Going with the usb installer seems easier so that you don't have to mess with your HDD partitions.

dothacker Posted July 26, 2012 Share Posted July 26, 2012 I added an 8gb partition on my HDD and made an installer there. after installing, i can just delete it with disk utility been doing that for a long time now.

EnzoFX Posted July 26, 2012 Share Posted July 26, 2012 I still can't decide if I should update or do a fresh install... Never done an update before, don't feel like setting everything up though.

OneBlueSky Posted July 26, 2012 Share Posted July 26, 2012 If your machine is known to work with it, no harm in upgrading from Lion! My laptop upgraded and runs perfectly in Mountain Lion. My desktop however is all out of whack. If your hardware is known to work though, go for an update. Certainly saves trouble and I didn't lose any performance or anything.
