If I boot with my MAC OS X.5 DVD (provided with my macbook), installation is possible. I’ve tried to create a new volume on the disk (GUID, mac os extended journalized) and I’ve tried to write zeros but without success it’s the same thing. Today, I want to install windows 7 via bootcamp but my 120GB drive hasn’t enough free space so i’m decided to put a new hard drive in my macbook (320GB) and to install snow leopard from the same usb drive than last year and it doesn’t work!!Īfter pushing on “C” key or option in order to boot on the usb drive, an apple appears on the display with a loading circle at the bottom and after 2 minutes I have a Circle with slash who is appearing and the mac os x install dvd volume never boots…I’ve tried with 2 differents hard disk and it’s the same but if I put my original disk drive in my boot (120GB with snow leopard already installed) the circle with slash does’nt appear and installation is possible. Hello everyone, last year I’ve installed on my macbook snow leopard on my macbook from a usb drive without any problems.
* Reboot the Mac holding down the “Option” key to pull up the boot loader, select the Snow Leopard install drive you just created rather than your default Mac OS hard drive * After the restoration is complete, your GUID partition will now be bootable by Mac OS X! * Alternatively, you can select the Snow Leopard Install DVD and restore directly from the DVD to the GUID partition * Select your newly made Snow Leopard 10.6 Install DVD image and restore this image to the GUID partition you just created OR… * Next, click the “Restore” tab within Disk Utility * Click OK to create the GUID partition (this will reformat the drive, ie: all data is lost) * Select the top option for “GUID Partition Table” – it MUST be GUID to be bootable!
* Select 1 Partition, then click “Options” below the partition scheme * Click “Partition” from the menu options * Select the External Firewire/USB device that you want to use as the boot drive for the upgrade Install Mac OS X 10.6 Snow Leopard from an external Firewire or USB drive * Click OK and wait for the image to be createdĮasy enough right? Ok so here’s how you create a bootable Snow Leopard installation drive out of your external firewire or USB hard disk. * Name the image and put it somewhere you can find it easily (Desktop) * Click the “New Image” button at the top * Select the Snow Leopard DVD within Disk Utility If you do need to, you can create a DMG file of the Snow Leopard disk, this is very easy. As some readers pointed out, this step isn’t required.
