I do a boot floppy disk about Windows 98SE and make a image type *.IMG

In CDShell.INI a give the cmd : memdisk /w98se.img

But when i start, i have this msg :

Loading boot sector...booting...

Disk I/O error
Replace the disk, and then press any key

How can i do for start OK!
Thank you for help

make sure that your bios has the FDD controller enabled and /or a floppy drive set if you can manually choose an A or B drive. (Though you will boot from CD, disabling the floppy drive in bios can cause floppy emulation to not work.)

Otherwise, if you know the floppy image is good and the above does not apply to you, try using diskemu instead of memdisk.

You must carefull about the type bootsector system about floppy disk

MS-DOS 7.1(98) bootsector type Win95
MS-DOS 8(ME) bootsector type Win95
DR-DOS6 bootsector type IBM
NT bootsector type NT

Use Winimage....

Command CDShell.INI : bcdw boot /FDD/msdos8me.img
