According to my experience, the method to burn bootable disc but not ISO virtual disc files is to find a CD of the same system. If you burn XP, find an XP system disk, and then use ultraiso to extract the bootable winxp system disk bootable boot file, then add the winxp file you want to burn to an ISO file, and then load the boot file extracted just now and save it. It is best to use a vmware virtual machine when you are burning, install and test first, and then burn it.
Use winiso to generate disc images, so that others can generate bootimg (winiso function), you can use
2 Try using Nero to make other bootable CDs into iso files, extract bootimg, and you can use it again
Both methods are exhausted and consume hard disk space.
Burn the boot disk with Nero without floppy drive
When we want to burn a boot disk, we need a boot source. This boot source can be a boot disk, an image of a boot disk, or a mobile storage device (MO machine). In our national conditions, most users will not use MO machines (price and purpose reasons). So when you want to burn a boot disk, you need to use a floppy disk as the boot source (there is no floppy disk image without a floppy disk), but what if our computer does not have a floppy drive? (Most commercial machines or some newly installed computers do not have floppy drives, the main reason is that they are used too little)
Note: Anyone who can start can be the startup source, not necessarily the startup of DOS, but Nero can only be started in DOS for the time being.
In this case, we can use the following method to make a startup disk, but this method also has its shortcomings, and what are its shortcomings will be described later.
1. Install a software called RamDisk98 (there is a corresponding version under Win2000, which is used to virtualize a part of the memory into a removable disk).
2. Set "Disk Type" to "Hard Disk" in the software settings interface, and set "Disk Size" to 5MB is enough. You can choose any drive letter, and you don't need to choose anything else. Restart after setting.
Although the Disk in RamDisk98 type can be set to 1.44MB or 2.88MB, neither of these modes can be formatted as a boot disk in the system, so it is useless. This may be a bug on the software.
3. After restarting, there will be an additional removable disk in my computer. Click "Format" to open the formatting dialog box.
4. When formatting, be sure to choose Full Format and choose to copy system files. That is, if Windows 98 chooses to quickly format, it will also force Full Format. Because it is virtualized with memory, it is extremely fast and the whole process is completed in less than a second.
5. After the formatting is completed, 4 files will be generated, three of which are implicit (No one who is DIY is not aware of it, right?).
6. Although the formatted disk already contains files that can be used for startup, we should also put programs or utility tools related to the startup disk. After all, there is 5MB of space available (if you want to put more tools, set Disk Size in the previous settings). At this point, the startup source is ready.
7. Open Nero Burning - Rom and create a new "Read-only CD (Startup)" task. In the "Start up mirror data source" in the "Start up" tab, select "Startable logical drive" and select the drive of the boot source according to the actual situation. The other options can be set and press the "New" button.
8. Drag the file to be burned to the list box and burn it.
9. Nero will report an error when burning, saying that the drive lock failed, ignore it. After the burning is completed, a bootable disc will be completed. The process can be implemented without a floppy drive.
Off topic: In addition to helping us burn the boot disk, Ramdisk is also a very practical software, you can try it out.
The boot disk made in this way is different from the general boot disk. After the general boot disk is started, it will be simulated as A:. This method is simulated as C: when booting, that is, it will be simulated as hard disk. After the simulation, the original C: will retreat to D:. This is the disadvantage of this method.
