Windows – Combine Multiple ISO Files To Burn A Single Bootable ISO Image in windows system

You'll need

• Software for creating iso images (I used k3b)
• Software for creating a bootable flash drive from a USB (I used unetbootin)

Creating the image

You need to create a bootable ISO. You'll probably have to select a boot file (for Windows 7 and likely 8, this is etfsboot.com). I used k3b to do this, but other programs support it and, in fact, I figured out how to do this largely thanks to a guide for a piece of Windows software. Here's what worked for me:

1. Open k3b
2. Go to New Project > New Data Project
3. Drag your files from the unpacked disk into the data section at the bottom
4. Click "Edit Boot Images"
5. Click New...
6. Select the boot image - if it's the same on Windows 8 (and it probably is) it'll be in the boot folder. I think the exact file you need is etfsbootcom. Do not be seduced by bootmgr in the root! It's not that one.
7. It'll ask about hard disk emulation. I used "no emulation"
8. The default options should otherwise be fine
9. Go to Project > Properties and in the writing tab check "Create Image" and "Only Create Image".
10. You need UDF extensions enabled for the filesystem defaults, but for me this happened automatically when I left it alone
11. Close that and "burn" (remember, you're really just creating the image but you still use the burn button) the image. Remember to set a file name.

Formatting the flash drive

You'll need a flash drive with the first partition formatted to NTFS and large enough to contain the Windows disc (4GiB was more than sufficient even for my universal 32/64 bit Windows 7 installer and should be good for Windows 8 as well). I used GParted. Here's what worked for me:

1. Unmount your flash drive if it's mounted - you can probably do this by right clicking it in your file manager
2. Open GParted
3. Select your flash drive from the drop down menu in the top right - it'll likely be called /dev/sd[LETTER]. Check that the size and partitions match! You do not want to accidentally use your harddrive.
4. Clear up enough space (you can just right click and "Remove" or "Resize" partitions, but be careful to back up data)
5. Create a new partition (Partition > New). The filesystem must be NTFS, the size large enough for your ISO and it must be the first partition on the drive (at least for Windows).
6. Re-mount your flash drive (eject/plug it back in or click it in your file manager)

Creating a bootable flash drive

You could actually do this in a few ways, but I used unetbootin (probably the easiest and most user friendly on Linux). Note that you will need to use an older version as recent ones have dropped support for NTFS formatted flash drives (build 494 should work). Here's what worked for me:

1. Open unetbootin (you'll need to run as root but it'll prompt you for a password)
2. Select the "Diskimage" radio button and enter the path to your ISO image
3. Switch the option for drive type from "USB" to "Harddisk" and select your NTFS formatted flash drive - be careful not to select your actual hard drive!
4. Click okay and wait. Once it's done, you'll have a bootable Windows flash drive

Be sure of your DVD writer supporting CD/DVD burning before you decide to burn it. It is very simple to know whether your computer can burn CDs and DVDs. Make use of the following guidelines.

FOR WINDOWS OS USERS:

Just check the name on your CD/DVD drive icon.

If the drive says DVD/CD-RW Drive, it can play and write to CDs and play but not write to DVDs.

If the drive says DVD RW Drive, it can both read and write to CDs and DVDs.

FOR LINUX OS USERS:

Usually the linux distro won't be equipped to interrogate your hardware. To do that you will need to open your Terminal and enter sudo apt-get install libcdio-utils. This will download and install the necessary tools for fetching out the info about your DVD drive. Now enter cd-info in the Terminal. It will reveal the CD/DVD drive info including the read and write capabilities.

Also, be sure of your file not broken in case of an iso kind. As well, use an undamaged CD/DVD.
