How do I Burn a "Bootable" DVD/CD Correctly?
Posted on 2011-02-14
This is embarrassing, but I have been burning certain bootable DVD/CD incorrectly for many years. When I insert it and set the BIOS to boot to DVD-Rom, I get the old, I guess DOS, (windows 98 looking) thingy,scrolling, before it finally stops at some sort of (DOS, I guess) prompt. As follows: A:\>
I have no idea what to type in there and I am not great with DOS. I especially have a problem with using the "CD"prompt in DOS. I really just wish these disks would just boot to the CD/DVD. Here is why it matters all of a sudden. I would like to have these CDs boot up @ the BIOS before windows boots (like safe mode) because what these disks are, is Anti-malware Kits with exclusive deep Trojan and Rootkit removers. And some other reasons, mainly the malware removing tools. I believe that it is when I try to make something bootable from an ISO, I am missing something or actually putting something extra in, like maybe a boot image (boot.ima, etc.) that I do not need. Who knows. Not I. That is why I am here.
However, all I get is this drive A: prompt. I am building these disks incorrectly and do not know what to do about it, so it is time that I ask you experts, after all these years of doing it wrong.
Now some of these disks I build are perfectly bootable and I have done them correctly. I have
correctly Built bootable cds and dvds before. Including Win XP, Vista, Win 7, Repair Disks, Recovery disks, UBCD4W, UBCD, Bart's, etc. they all work, but some of them DO NOt and I get the "A" prompt instead because I did something wrong. For years, I cannot seem to get Hirem's Boot Cd to boot, for example. The trojan removal toolkit cd I am talking about is a beauty called SARDU. I just cannot seem to make it boot from the BIOS. I just get that prompt. I have ruined 3 cds. If they would boot, I could do my malware removal outside of windows and life would be so much better.
So THE QUESTION IS: How do I correctly burn an ISO image so that it is bootable? Or Maybe How do I prevent a burned ISO from booting to DOS?
Some of them ISOs appear to be much more difficult than others.
I want this one badly, so that is why I am finally asking the Experts.
And I am thanking you Experts in advance because I know that you know what I am doing wrong.
