“When the computer boots from the flash drive, it runs Linux
which can access the FAT32 partition and any other drives in the
computer as well as its own partition. As it is a normal Linux
system, it remembers your settings and you can store files in the
home directories, in the shared FAT32 partition and on the other
drives in the computer.“This recipe borrows ideas from my earlier article How to make a
virtual computer real. The method used is to create a virtual
machine and then transfer the virtual disc image to the USB drive.
My computer runs Debian 6 but the procedure should work on most
Linux distributions. This recipe works for me but I offer no
guarantees!”
