seems to me were I in your shoes,I would bootup using the win98 startup disk.
then I would choose without cd support.
thereafter once the floppy was done makin' it's noise & at the a prompt,I would then type in -> edit
then key in enter.
you would be at a blue screen,key in and let go in this order,
alt,f,o
that will throw up the good ole dos editor.
by using your up/down/left/right arrow keys and or the Tab key you will be able to navigate to hopefully any folder/file.
now should you have another hard drive installed you could use the dos command ->copy<space>c:\myfile.whatever extention<space>d:\
then key in enter.
I read the book"Dos for Dummies" long ago when using win95B since I believed windows layed on dos,so I learned the basics of dos to manipulate winDOwS.
If you do not understand this then I would suggest reading maybe?
it's a great book had me laughing my you know what off.
hilarious book,but very informative.
hopefully I've helped out some?
