Forum: UltraISO Topic: Bootable->Make Floppy Image issue started by: rfw Posted by rfw on Aug. 04 2011,14:34
I have been trying to use UltraISO to make a bootable CD-ROM from a bootable MS-DOS stick under Windows 7. With 9.3.6.2750 and with 9.3.6.2766, Bootable->Make Disk Image reports Error: No Floppy Drive Found.In contrast, Bootable->Make Floppy Image reports the HDDs and USB stick on the system and creates the right size .ima file. Bootable->Load Boot File changes the image state to "Bootable CD/DVD" and that state is saved in the .iso file, but when the .iso file is burned to a CD-R then the CD-R does not boot. It seems like a bug that Bootable->Make Disk Image should report Error: No Floppy Drive Found. And it seems like a bug that Bootable->Make Floppy Image should report the HDDs instead of no Floppy Drive Found. These leave me wondering if the .ima file that resulted from the Bootable->Make Floppy Image is valid. If that is not the case, then what am I doing wrong that my CD-R does not boot?

you are trying to write an bootable iso on a CD-R ![]() a cd is about 700mb ..an image is a lot bigger !!!! the writing proces can not start when using a cd -r and when you extract the image from a bootable usb stick by using ultra iso he tels you if this is a bootable or not : if not you have to load the boot file ... you can find this on google look for.... windows7.bif ore you can use ultraiso to extract the boot sektor from cd/floppy /HD Posted by rfw on Aug. 05 2011,12:22
In this case, the USB stick that has the bootable MS-DOS system is only 256 MB. Why would that not fit on a 700 MB CD-R? When I save the .ima file it is only 250 MB, so why do you say that an image is a lot bigger than 700 MB? |
