I am trying to install OS X Snow Leopard from a USB flash drive. for this purpose i arrange 16 GB USB and completed above mentioned two steps only. at the third step i get Image scanned error message. while resolving this, i got "unable to scan Mac OS X Install.dmg. (invalid argument)" error… Any help on this would be helpful.

Yes, after booting into the USB drive and before you start the install process, Select Disk Utility from the menu options (I believe it's under Tools). Then format with Mac Journal the Hard Drive. This will clean everything off.

Hi,

This worked perfectly! One question, however. I purchased my MacBook Pro on Ebay and I was hoping this would do a clean install (wiping all the files and allowing me to create a new admin account). It looks like it just did an update, however and I didn't see an option for a clean install. Should there be one?

Thanks!

This doesn't seem to be working for me. After reading all of the comments the only reason I can think is that my flash drive is not "GUID" formatted. When I go into Disk Utility it says "disk format: Mac OS Extended (Journaled)". I presume this means it's not "GUID" formatted. Is there any way of making it GUID formatted without starting from the beginning? I live on a pretty remote island in Thailand so technology and help in general is quite hard to come by!

I am running 10.4.11 on a MacBook and I created my boot disk using a legit copy of Snow Leopard. However, the flash drive that I had posted to me from the mainland wasn't quite 8GB, it was 7.6GB, the same size as the file. I got an error when I first copied created the disk image saying it hadn't worked, but when I insert the drive into my MacBook it appears to work fine. Is it possible that one or two files didn't copy over correctly and this is why it's not working?

In doing this will I lose all of the files I have on my computer? If so, is there a way to install snow leopard so that my files will be saved? I do not have anything big enough to backup my entire computer, however all that I need to keep is pictures and music.

I think you just answered your own problem. Sounds like your HD is bad and files can't be written to it.

Time for a new HD.
