Not all USB devices are created equal. By that I mean not all USB flash, pen drives
can be made into a bootable device. The best way to create a bootable USB drive
is to use a utility that writes the files to the device. You can not do this to
an external USB hard drive, external hard drives take the same procedure that a
normal hard drive does.
(To make a hard drive in an external usb enclosure
bootable requires you to remove the drive and install it into a computer, this
procedure is some what involved and will invalidate a warranty if it is a new
device, if you want to do the procedure contact me through my support page.)
I have found a couple of utilities that will make these devices bootable:
(Be sure to read the readme.txt file for both of these fine programs, I have used
the HP program for some time and have not had any problems with the
creation of a bootable pen drive)
Now that you have the utility you also need a bootable floppy with the
Autoexec.bat and config.sys files. Once you have created the boot device you can
copy any other files you may need on to it.
(Note: Check the autoexec.bat and
config.sys if you are loading any drivers, the path has to be C:\ because when
you use the usb device to boot the computer it is the first drive that the BIOS
will see.)
Now you need to test your new bootable device just incase you need to use it, you don't want to rely on something that "may work!"
