So let's start !
What You will
need:
- Windows
computer with access to the BIOS (BIOS should not be password protected)
- Kon-Boot -->
[direct link below]
After downloading, delete everything on your USB and extract everything from
the zip archive to the USB. Run a file
called KonBootInstall.exe and wait for the CMD box to open up, it will asks you
for the letter of the drive you want to install Kon-Boot onto. Type the letter
of the USB drive and press enter. Open the USB drive and it should have 3 files
in it.
The files
should be: [grldr, konFLOPPY.img, menu.lst]
Your USB is
ready!
How to use it
1.Plug in
the USB (if it isn't already) and restart the computer.
2.Go to the
BIOS [press Esc or F2 or F10] this may vary depending on your computer brand
3.You're in
the BIOS, now we have to boot from the USB drive. To do this, look for an
option such as Boot Order, Boot Sequence, First Boot Device and select USB as
the first device to boot from.
4.Now your
computer should boot and come to a menu with one option "Kon-Boot" or
"Kon-Boot Floppy Image". Hit enter and let the computer start up.
After
Windows has started you should be on the screen where you need to put the
password. Just leave the password field blank and click login.
I have tested
it on the following systems: Windows XP, Windows 7 32 & 64bit.
I take no
credits for the Kon-Boot program.
