WinISO Help - Make ISO from CDROM

How to create an ISO from a CD-ROM Disc

Press "F6", or click 'Make ISO From CDROM' in 'Actions' menu. The "Create ISO" dialog will pop-up.

Please select your CD-ROM drive that holds the CDROM Disc, and enter the destination ISO file name. Now you can click the 'Make' button to begin making an ISO file.

What's difference between 'ASPI' and 'File' mode?
ASPI mode declared that WinISO use a system-internal driver to read from the CDROM, it'll get more efficiency and high making-speed, and it can save the boot-information in the ISO created from a bootable cd. The default option is 'ASPI' mode and we recommend you use 'ASPI' mode to create ISO from CDROM. If you found that 'ASPI' driver report 'Can not use ASPI' then you should choose 'File' to make you ISO, but the 'File' has a problem that it won't save the boot information in a bootable ISO.
