Create a bootable ISO image file from a bootable CD/DVD?
Practically every search result changes the expression to "How to make a bootable CD". What I would like to do is make an ISO file that, like the CD it comes from, is bootable. I was trying to burn a non-bootable ISO file to a USB flash drive, but I suspect that somehow extracting everything from the bootable rescue CD and making a bootable ISO file would be easier. But so far that's like pulling teeth, too. I have followed several different directions for making a non- bootable ISO file into a bootable ISO file, the instructions are simple enough, but have failed. I have the bootable CD right here. So I'd like to find something to extract the whole bootable thing and to make a bootable ISO file out of it. Thanks. |

Or, if small enough, from say, a floppy diskette. There's quite a few of those tools. Some, have a menu where you select the actual OS type of the origin CD (or ISO9660), implying there are specific things that need to be fixed. http://www.howtogeek.com/127377/the-...nux-usb-drive/ If you use imgburn, to say, convert a WinXP installer CD into an ISO9660 file, then immediately turn around and burn a blank from the ISO9660 file just made, the new disc will be bootable. The .iso file seems to capture what makes it boot. But just working with the file system portion (i.e. use a tool which only extracts the files), might not be enough to get everything. And perhaps the El-Torito spec will help explain that. Paul |

The CD is bootable. But I want the USB to be bootable. Even Microsoft can make a utility that puts a bootable ISO image on a USB. But the ISO image that Macrium produces is not bootable (unless it's going to the CD). Seems to me there would be a tool that copies the data/bits from a bootable CD to make a bootable USB drive. I'm sure it would require some formatting changes, but it would use the same operating system and data. Again, I've seen some stuff about making a non-bootable ISO bootable, but it ain't working yet. -- Or, if small enough, from say, a floppy diskette. There's quite a few of those tools.

Create a bootable ISO image file from a bootable CD/DVD?
The tutorial worked, even though the boot USB requires user input
before proceeding to the restore screens. Apparently using a Flash Voyager (USB drive) might have been why previous attempts failed. This time after it failed, a Patriot Xporter was used and it worked. But using Yumi will be better since it's freeware, it will be stowed in my system software folder. |

But using Yumi will be better since it's freeware, it will be stowed in my system software folder. I'm still confused here in this thread John. You want to transfer a bootable CD to a bootable USB flash drive? If so, what is the OS that is bootable on the CD? Because the method is different depending on the OS. For example, I have created bootable USB flash drives for the following OS. Puppy Linux Ubuntu Linux MS-DOS v7 BartPE (like a WinPE clone) WinPE -- Bill Motion Computing LE1700 Tablet ('09 era) - OE-QuoteFix v1.19.2 Centrino Core2 Duo L7400 1.5GHz - 2GB RAM Windows XP Tablet PC Edition 2005 SP2 |

It is built into Macrium. 1. Start Macrium 2. Click "Other Tasks" 3. Select "Create Rescue Disk" 4. Follow the instructions and point it to where you want it to go. -- dadiOH ____________________________ Winters getting colder? Tired of the rat race? Taxes out of hand?

Create a bootable ISO image file from a bootable CD/DVD?
The method is not "in plain sight".
I wasn't trying to create a bootable Windows PE USB stick. I was trying to clone the other one, a Linux rescue CD. And as I've already said, I found the solution. I was searching too broadly. I was also using an incompatible USB flash drive.

Create a bootable ISO image file from a bootable CD/DVD?
Looks like the closest thing I've found for cloning the Macrium
Reflect boot CD to a USB drive is (unetbootin-windows-585). But it too includes a boot loader. Without knowing how to change the boot loader settings before they are "burned" to the USB, yet, would be better if the thing doesn't need user input before it gets to Macrium Reflect's restore dialogue, just like the CD does. |
