Hi, sorry if this question is in the wrong place, I'm having terrific trouble trying to install Snow Leopard.
I have a blank 16gb USB, I went to Disk Utility, erased, created a GUID partition and then moved onto Restore, I selected the new USB as the Destination and the (mounted) Mac OS X Install.dmg as the Source. I clicked 'restore' and it began 'copying blocks'. This appeared to be successful after about 25 mins.
My problem occurs at this point, if I go to Startup Disk the new USB Mac OS X install shows up, if i click it and press restart it simply boots back up in Tiger. If I shut down and restart holding Alt no other option appears than the original Macintosh HD (again booting it up in Tiger). It's as if it cannot see there is a USB there at all, but as I say it does recognise it in Startup Disk.
Is there any reason that the iMac wouldn't recognise the USB? The iMac info is:
Hardware Overview:
Model Name: iMac
Model Identifier: iMac5,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.16 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache (per processor): 4 MB
Memory: 1 GB
Bus Speed: 667 MHz
Boot ROM Version: IM51.0090.B09
SMC Version: 1.9f4
(not sure if this helps?). I did speak to an Apple tech support man who said there should be no problems with booting from this method (before I attempted it!).
I have been trying now for 3 days and get the same result each time!
Can anybody help?
Thank you in advance.
