Yup, that'll work.
Also, most new computers today have the ability to boot from several different media.
I've found the USB Floppy drive to work on almost all new computers.
I carry one with me on every call, just in case I might need it.
An alternative media for Ghost is a bootable flash drive.
A little program from HP makes that possible.
But why you're hung up on PC-DOS is beyond me. ???
MS-Dos, like from Windows 98 or ME is much better.
And if you decide to use DOS utilities on your Ghost boot disk, like
FDISK or Format, or even Scandisk, Edit or whatever, they will run properly. NOT so, if you're booting up in PC-DOS.
That OS is just too old to be of practical use for a tech.
Building a boot CD from a floppy, you're limited to the 1.44megs available from the DSHD floppy disk.
If, however, you build your boot disk on a bootable flash drive, you can install all sorts of little Utilities to make that boot disk much more useful.
I made my first bootable Flash Drive off of my Ghost 2003 boot floppy, then I added NTFS4DOS and several other Utilities that I might need.
Then using Nero, I burned that flash drive to a CD.
You can then add things like "Memtest86", HD testing utilities and anything else you might need.
Good Luck,
