I got
stuck today. How do I run an(y) ISO image from a pen drive?? I had 2-3 usb
thumb drives lying around but no blank CD. After a few hours of search on the
internet, finally managed to run not just one but four different ISO images
from my thumb drive via a menu! To cut the long story short, this is what I
did:
1.
Took a clean thumb drive (quick formatted it with Fat32 option).
2.
Fired BootMyISO application, selected my thumbdrive and clicked on
next to install it on the thumb drive.
3.
I browsed the thumb drive and found the following 4 files:
grub, memtest86+-4.00, menu and syslinux.cfg
grub, memtest86+-4.00, menu and syslinux.cfg
4.
I copied the SeaToolsDOS223ALL.ISO file (I wanted to boot from
this ISO) to the thumb drive.
5.
Opened the original menu file and found the following structure:
default 0
timeout 30
color
cyan/blue white/blue
foreground
ffffff
background
003f7d
title
Memtest86+
find
--set-root /memtest86+-4.00.iso
map --mem
/memtest86+-4.00.iso (hd32)
map --hook
root (hd32)
chainloader
(hd32)
# title
Parted Magic 4.5 ISO Boot
# find
--set-root /pmagic-4.5.iso
# map
/pmagic-4.5.iso (hd32)
# map --hook
# root (hd32)
# chainloader
(hd32)
# title Test
ISO
# find
--set-root /testname.iso
# map
/testname.iso (hd32)
# map --hook
# root (hd32)
# chainloader
(hd32)
6.
I updated the above menu file to suit the ISO that I had added and
the final content looked like the following:
#First 5
lines from the original menu file
default 0
timeout 30
color
cyan/blue white/blue
foreground
ffffff
background
003f7d
#Last 6 lines
from the original menu file with changes
title Sea Tools DOS
find
--set-root /SeaToolsDOS223ALL.iso
map /SeaToolsDOS223ALL.iso (hd32)
map --hook
root (hd32)
chainloader
(hd32)
# Template
for future use to add more ISOs
# title Test
ISO
# find
--set-root /testname.iso
# map
/testname.iso (hd32)
# map --hook
# root (hd32)
# chainloader
(hd32)
7.
Saved the menu file.

That’s it folks! Now just reboot the PC and …
Tools needed: BootMyISO (Open source. Although now discontinued, copies can be found all over the internet including the link below)
