Looking for software under DOS that can extract a bootable floppy disk image IMG into a bootable floppy disk.

My problem seems simple: Isn't undisk.exe enough?

But when actually tried in a DOS batch process to make a floppy disk, it can't boot.

After trying several kinds, only unimg.exe can completely extract a bootable floppy disk image IMG file to a floppy disk to make it bootable under a DOS batch file. Unfortunately, unimg.exe runs extremely slowly.

Looking for software under DOS that can extract a bootable floppy disk image IMG into a bootable floppy disk and has a relatively fast running speed!

Using HDCOPY. This veteran IMG creation tool is quite suitable, and the reading and writing speed is relatively fast.

WINIMAGE is also okay

But attention should be paid to the boot file

Hmm. The function of Undisk is purely to extract the files from the IMG file and cannot rewrite the boot sector of the floppy disk, so Undisk cannot be used to make a bootable floppy disk. In DOS, besides HDCOPY, you can also use DI (this thing seems to be in Wengier's MSDOS 7.1 boot disk), and the usage is also very simple:

DI /R imgfile A:

WinImage can also be used, but it must be used in the Windows interface.

Can the HD-COPY.WInimge mentioned by the几位 upstairs be used in DOS batch processing? Why can't I find their usage as DOS commands?

HDCOPY has command-line parameters, but these parameters only set some options. Directly run HDCOPY to enter its interface, select "Get from file", enter the full path and file name of the IMG, HDCOPY will read the IMG file and store it in the buffer, then select "Write" from the menu to completely decompress the IMG to the floppy disk.

Thank you for the information. I wonder where I can find DI. Is it in the Wengier boot disk? I'll go find it and give it a try!

Also, thank you to the other enthusiastic experts for their pointers. But my requirement is to not enter the Windows interface, to run in command mode under DOS, and that the batch processing cannot pause.

Brother JonePeng:

I looked at Wengier's disk and only found a DI1000DD.SYS. I'm not sure if DI refers to it. How do I use it?

No. It should be in the Wengier's MSDOS 7.1 floppy disk installation version. After downloading, it is a compressed package, and there are several files such as di.exe, msdos710.img, hdcopy.exe, makeboot.bat in it.

Thank you so much, Brother JonePeng! You have solved a difficult problem for me. I finally found the software I need. The test result is that DI (full name is DiskImage) can quickly extract the boot floppy IMG file to the floppy disk under DOS, and the made floppy disk can start normally completely.

Why is such a useful DOS software as DiskImge not introduced in several famous DOS forums? I have searched all the software for extracting IMG and didn't find it. If it weren't for your help, I wouldn't have known about such a useful software.

By the way, I would like to mention a problem that I asked for help not long ago and didn't get a result:
The DOS software that can extract files in ISO (generated by UltraISO) to a certain directory under DOS, the premise is still not entering the Windows interface, can be used in the DOS batch processing and will not terminate the batch processing.

Thank you for your help again!

Regarding decompressing ISO under DOS, I haven't tried it. The Autoit moderator once introduced a tool like this, please see:

You mentioned LoadISO. I have tried it. It can only recognize the ISO virtual disk under DOS, but the files in the disk cannot be operated, that is, cannot be copied. According to the introduction, it can install the system from the ISO on the hard disk under DOS, but I can't succeed in extracting files from the ISO. It seems that the software I'm looking for really can't be found!
Still thank you for your enthusiastic help
