Yes OS X can boot from a USB connected drive. Is that what you wanted to know?
As to your "Is that the only option available" question, option available for what? What are you trying to do with, or get from, the old drive?

thanks for that information. I plan to reinstall osx lion on the new 750 gb hard drive that I've just installed. since osx lion didn't come up with a cd as compared to its predecessor. the only way for me to do this is to boot from my old hard drive using an enclosure. but since the enclosure broke yesterday. I don't know how to approach this problem. do i need to purchase a usb version of the lion?

How old is your Mac? Are you using a Macbook Pro, Mac Pro or iMac
You could by a Lion install USB thumb drive from Apple but all you need is a SATA to USB adapter and or an Enclosure. you should be able to find either of those locally for much less then what Apple wants for the Lion thumb drive ($69).
What you should of done is use the Lion Recovery Disk Assistant download, from Apple, to create a USB thumb of the Recovery HD. you can still do that by putting your original drvie back in the system or booting from it once you have the new enclosure or SATA to USB adapter.
If your Macbook Pro or iMac is from 2010 you may be able to boot the system from the Apple Online Recovery HD system. That boots the computer from over the internet to the Recovery HD. From there you can partition/format the new drive then download Lion and install it.
Boot the system and hold down Command+r (if that doesn't work then try Command+Option+r) until you see a globe in the center of the screen. Have the computer connected to your internet router with an Ethernet cable (Wireless works but it is better to use a hard wire connection).

So you got one of your Lion install USB thumbs to work? Or you made the USB Lion Recovery HD?
