For those who do not have a soft drive installed, most of them will choose a virtual soft drive, but unfortunately the capacity of the virtual soft drive is too small, so they have to be limited in terms of functionality.

ISOEMU is an interesting software. After installation, you can use the ISO image file on the hard disk to guide the system, so that you do not need to use a dial when installing Linux. The principle is to use GRUP to boot the ISO file on the hard disk. Of course, this ISO file is still created as a virtual optical drive to boot the system. It supports FAT32 and NTFS file systems, however, only DOS-based access is supported, that is, INT13h-Based Disk access.

Functions of various files in the ISOEMU package

ISOEMU is free of charge. If you need it, you can download it from here and release the downloaded compressed package. Five files are available. The functions of each file are as follows:

IELDR: Loader main program of ISOEMU.

Isoemu. ini: configuration file of IELDR.

Isogrub. iso: a bootable ISO image file provided by software developers. This file is small and only 1.3 MB.

Eltorito. sys: the optical drive, which works with mscdex.exe to access the virtual optical drive created by ISOEMU under pure DOS.

ISO image file boot System

If you are using a Windows 2000/XP operating system, you can use the NTLDR menu to load IELDR. The procedure is as follows:

Step 2: Release the program file

Copy the IELDR file to the C-drive root directory to add isoemu to the OSLoader of Windows 2000/XP. ini and isogrub. the iso files are released and copied to the C root directory.

Step 2: Modify the boot. ini file

Open the Boot. ini file in the root directory of the C drive in notepad and add the following content in the last line. Of course, you can also enter other content: c: IELDR = "Boot from the ISO Image File ".

Step 2: Modify the isoemu. ini file

By default, ISOEMU starts the built-in isogrub. iso image file boot system, of course we can also start other ISO image files, but must be on the isoemu. the last line of the INI file is modified. Note that only the 8.3 file format can be used. Otherwise, it cannot be correctly recognized.

You can use software such as WinISO to add common DOS External commands or third-party tools and save them again.

Restart the system. You can see the "boot from ISO image file" option added in the boot menu. After selecting this option, you can use isogrub. the iso image file is used to boot the system. However, it should be noted that ISOEMU is still a virtual operation, so we do not have to have high expectations for its running speed.
