Software recommendation: no optical drive does not matter to install a free virtual

Many laptops or PCs do not have a physical CD-ROM drive installed, but many software packages exist in the form of CD-ROM images, so it is a lot of work to unzip them each time and some of them cannot be used because they do not recognize the CD-ROM drive after unpacking. This time, the use of virtual CD-ROM drive software OSFMount will be able to emulate the CD-ROM drive to run the image file. In addition, the software can also be used to create a virtual image of the memory, or create an empty image file that can be read and written.

If you run the 32-bit OSFMount installer on 64-bit Windows, an error message pops up indicating that it can only be run on x86 processors (Figure 1). The green version of 32-bit OSFMount, however, will run normally on 64-bit Windows.


1. Emulate a normal image as a read-only optical drive

If we have a CD-ROM image file, such as the ISO CD-ROM image of Windows 7, we can use OSFMount to quickly emulate it as a read-only CD-ROM.

After running OSFMount software, execute the command “File → Mount New Virtual Disk” (or use the shortcut Alt+N), or you can load the image directly by clicking the “New Mount” button. In the subsequent pop-up window, select the source file type as “image file”, then specify the path to the image file, choose the default settings for the image file offset and disk size, choose the disk drive letter as the free one automatically detected by the software, or specify a free one yourself, and choose the disk type as CD-ROM drive (Figure 2). After confirmation, we will see a list of disc drive and image file items in the OSFMount window.


Tip: After the image file is loaded, a new disk letter will appear in Explorer. At this point, even if you close the OSFMount software, this disk drive will not disappear. If you want to uninstall the disk drive, you need to go through the OSFMount software window, select the disk drive item and click the “Uninstall” button to uninstall it. 2.

2. Install the image file in memory

If you have enough space on the memory stick installed in your system, you can also mount the image file in the memory to use it. This will allow the virtual CD-ROM drive to run at a faster speed. To mount the image file as a memory image file, just select “Memory Image File” in the “Source” selection item and load it. 3.

3. Create a read/write empty image file

We can also create an empty read/write image file according to our actual needs. After clicking the “New Load” button, select “Source” as “Empty Memory Disk”, then specify the disk size and unit (e.g. 1GB), specify the disk letter and disk type. Deselect the “Read-only disk” option and click the “OK” button (Figure 3).


After that, we get a read/write drive in Explorer. Although the memory virtual image file will disappear after shutting down the computer. However, before unmounting it, OSFMount will package it as an ISO file, which can be saved and mounted as a virtual disk after the next boot.
