A recent Mac with an Intel processor can boot from a USB 2.0 Hard drive. Earlier Macs could only boot from a Firewire Hard drive. When you turn on the Mac hold down the Option (alt) key. This will cause the Mac to scan for all available bootable drives. Select the one you want to boot from and it will start up from that drive.
Only if you can boot from it. Most new computers can boot from a USB drive, but older ones may not be able to.
The USB flash drive on your MAC does not lock. To remove the USB drive just firmly hold it and gently pull from the socket. Flash drives are a very convenient way to save data from your hard drive.
If you have special software when you insert your usb key to Mac it allows you to access. Or yiou can actually protect you Mac with password(+usb key). If you are intrested in soft - ProteMac Logon Key is only i know. http://www.protemac.com/logonkey/

Get unetbootin from ubuntu's website. Select the ISO from your hard drive then reboot and boot from USB! Voila!
If you have a USB drive and your BIOS supports booting from a USB device then try that.
Mac answer: Your hard drive might be damaged. Boot up your mac with the DVD-disc or USB-drive that came with your mac and let Disk Utility try to repair your drive. If successful you will be able to start your Mac again as normal. If you are on Apple Care or if you are on your first year within purchase, it is advised to backup as much data as possible before taking it to an Apple Certified Repair shop to get yourself a new Hard drive.

In order to do that your motherboard should support boot from USB, Fireware or E-SATA. If it does, you need to go to BIOS options and choose option "Boot from USB device..." or something like that. E-SATA and should be available as any other hard drive. Same is true for Fireware.
One can perform a hard drive recovery by removing the failed hard drive and hooking it up to an alternate computer through a USB universal drive adapter or if you have a Mac, using a FireWire cable to hook your nonworking Mac to a working Mac then pressing the T key as you power it on.
If you mean - to use a USB drive to boot up your computer instead of installing the software on the computer's hard-drive - theoretically, yes. HOWEVER - if your USB stick went faulty or you lost it - you wouldn't be able to use your computer !
It depends on what you have set-up for the computer to boot-up. A normal setting is for it to boot from the hardrive or if you are on Linux the setting normally is; BOOT-UP LINUX *-Disk Drive *-USB Ports(sometimes, but not normally) *-Hard Drive *-Floppy Disk
I'm not quite sure what you mean, so I'll give you both answers: "How do you use a hard drive for Mac and Windows on the same machine?" On a mac, insert a Windows install CD or DVD, and the computer will ask you if you want to set up windows to run alongside mac. In the process you will partition the hard drive, so you will kind of have a windows hard drive, and a mac hard drive, but on the same disk. "How do you remove a Mac hard drive and put it in a Windows machine?" I am not a technical expert, so you might want to look up "How to remove and install a hard drive". All I know is it probably won't fit, so you might need to buy a hard drive enclosure and run the drive from a USB port. Hope one of these helps! If not, please revise your question
