Floppy only or CD-Image Spinrite do not frezze why?
UBCD Final or why not?
Grub4DOS can boot ISO Images Syslinux not that is why i use UlitmateBootCD 3.4* with CDShell and BCDW for booting ISO Images like Acronis Suites (Disk Director, True Image).
In the future Floppy Images going rare and more ISO Images (Notebooks have no Floppy).
