CentOS download and burn bootable ISO image Worked Example

This is a worked example of downloading CentOS linux 6.4 for old 32 bit hardware and creating a bootable DVD using a Windows 10 system.
The same disc burning process worked for CentOS 7 64 bit version.

The steps below taken mostly from the CentOS web page "How to burn an ISO image CentOS" were:

downloaded the CentOS ISO file CentOS-6.4-i386-bin-DVD1.iso at http://vault.centos.org/6.4/isos/i386/
and the CentOS7 file CentOS-7-x86_64-DVD-1511.iso via a local mirror site https://www.centos.org/download/mirrors/

downloading and using sha256sum.exe to check the download file.
sha256sum.exe is used from the Windows command prompt and showed the following for centos 6.4:
3935c88644ee390285e12093003486a60322a1cb9bc542f3d2bfb40d52b131d8 *centos-6.4-i386-bin-dvd1.iso
I compared the check sum above to the corresponding value in the file http://vault.centos.org/6.4/isos/i386/sha256sum.txt
see https://wiki.centos.org/TipsAndTricks/sha256sum for more information on checking the file and downloading sha256sum.exe

As it was the first software mentioned on the Centos website, I then downloaded a trial copy of Roxio Easy Media Creator 9 software

Roxio Creator 9 software

Warning! Although the creation of the CentOS bootable disks was successful, it seems that the Roxio Creator 9 software wasn't designed for Windows 10 or uninstalling.

A Google search of "uninstall roxio software" will show how difficult it can be to uninstall the software.
After making the disks I downloaded revo uninstaller and it removed the Roxio software.

Starting the Roxio Creator 9 software

On my copy of the Easy Media Creator 9 the newly installed software started with a "Script error" which I just pressed Yes to.
It is a concern that each time the Windows 10 system starts there is now a question about issech.exe relating to Windows shield.
(download date 7th November 2016)

I chose the option "Copy".
On the screen shot below the third option on the left to click on is "Burn Image".

Burn Image to Disc Screen

Before starting the Roxio software I'd put the downloaded ISO image file into a separate folder of its own to make it easy to select the right file.

All that was needed was to use the browse button and select the iso image file,
followed by pressing the red circular button on the bottom right of the screen.

The ISO burn process took 12 minutes for CentOS 6.4 and 14 minutes for CentOS 7.

Checking to see list of files on DVD

Using Windows explorer the disc showed a name of CentOS_6_4_Final
and included directories such as images, isolinux, Packages and repodata.

Checking to see if DVD is bootable

On my Windows 10 PC I started up the system pressing F12 about once per second after turning on.

This allowed access to the boot menu. I chose the DVD drive to boot from.

Once it was apparent that the image would boot ok, having shown the Centos logo and options, I turned off the system as I wasn't intending to install on that PC.

Both the Centos 6.4 and Centos 7 DVD disks booted up ok giving about a minute's warning before starting up.

Unfortunately although these disks booted on the Windows 10 64-bit system, the Centos 386 32-bit version failed to boot on the 32-bit system.

Update as regards old 32-bit Dell system

I decided to create a CD (instead of a DVD) with just the minimal iso of CentOS 6.4 on the old 32 bit system.

Using this on an old Dell Dimension 8200 system CentOS 6.4 minimal 386 iso then booted using the CD disc in the DVD drive but it did not work in the CD drive.

Conclusion about Roxio software

The software made three bootable CentOS disks without any wastage or problems.

There were a couple of issues with the script error on startup, isuspm.exe and issch.exe requests on PC startup.
Once I'd made the CentOS disks, I uninstalled Roxio with the revo software, the issues with these exe's stopped.
