ok so im trying to install mac os tiger off a usb, i understand you need to make it a guid in order for it to be bootable..but my imac 4g is running mac os x puma and the disk utility has no options tab to make the usb guid..so im stuck is there a way to make it? ive tried terminal and that was a bust as well some how on a windows computer? i own one of those too?:) thanx in advance
 
The G4 iMac will not be able to boot from a USB device. Better try a Firewire external HDD and the Apple Partition Map, as GUID is for Intel Macs.


The following screenshot shows the options in Disk Utility and the explanations. Ignore the green box, as it is related to a guide for replacing HDDs in an Intel Mac.

PPC Macs will not be able to boot from GUID formatted devices.
And USB as boot interface is not supported with G4 Macs and in Puma.
GUID was introduced with 10.4 during the switch to Intel, thus it shouldn't and wouldn't be an option in Puma.
If you can't use optical media for any reason, you need to get a Firewire HDD and format it with Apple Partition Map as partition scheme and HFS+ (Mac OS Extended) as file system / format.

The "About This Mac" window should tell you the CPU speed at least.
System Profiler is located in Macintosh HD / Applications / Utilities.
