This document explains how to create under Linux a LiveCD running FreeDOS that automatically start TestDisk.

• Download FreeDOS OEM CD-ROM disc builder assistant

wget -N http://www.fdos.org/bootdisks/ISO/FDOEMCD.builder.zip

• Download the DOS version of TestDisk & PhotoRec

wget -N http://www.cgsecurity.org/testdisk-6.11.3.dos.zip

• Cleanup the work directory if it already exists

rm -rf FDOEMCD

• Uncompress the archive

unzip FDOEMCD.builder.zip

• Uncompress latest version of TestDisk & PhotoRec

cd FDOEMCD/CDROOT
unzip ../../testdisk-6.11.3.dos.zip
mv testdisk-6.11.3 testdisk

• Create an autorun script

echo "@ECHO OFF" > AUTORUN.BAT
echo "CLS" >> AUTORUN.BAT
echo "CD TESTDISK\DOS" >> AUTORUN.BAT
echo "TESTDISK.EXE" >> AUTORUN.BAT

• This script must use DOS newlines, not Unix ones

unix2dos AUTORUN.BAT

• Create the iso image using mkisofs

cd ..
mkisofs -o testdisk.iso -p "Christophe Grenier" -publisher "www.cgsecurity.org" -V "TestDisk CD" \
-b isolinux/isolinux.bin -no-emul-boot -boot-load-size 4 -boot-info-table -N -J -r \
-c boot.catalog -hide boot.catalog -hide-joliet boot.catalog CDROOT

• Boot from this iso image in qemu emulator

qemu -localtime -boot d -cdrom testdisk.iso -hda disk.dd
