I would like to boot DOS from the USB CD-ROM to run a powerquest restore utility for restore the system on HDD. The system without FDD or internal CD-ROM.

I use nero 6 to make a bootable CD-ROM with FDD emulation (The usbaspi.sys, usbcd.sys and with correct config.sys and autoexec.bat included).

While the booting, the start up found the CD-ROM then unable to load the other files and command.com

I got a message like this one :

VID057B_PID0000 FS
ID:0 LUN:0 = DVD/CDRW RW9120 1.36

The following file is missing or corrupted: USBCD.SYS
There is an error in your CONFIG.SYS file on line 5

The following file is missing or corrupted: COMMAND.COM
Type the name of the Command Interpreter (e.g., C:\WINDOWS\COMMAND.COM)

I try many methods but unable to solve. Please help!!!
