How can I install a mini system onto a USB flash drive?
Can a system like that be used to boot?
Also, after booting, can I use this operating system to access the computer's own hard drive?
That is, there is no operating system on my hard drive. When I want to use the computer, I boot from the USB flash drive. Then I use the computer from the USB flash drive, and save the data on the computer's hard drive. Once the USB flash drive is unplugged, the computer can no longer be used.
Is it possible to make a USB flash drive system like that?
