For whatever reason, Cisco only post 'non-bootable' ISO images on CCO for download. In some urgent situations, you might need a bootable disc to recover the system (or your client/boss would shoot you in the head). Here's the procedure to make a non-bootable ISO image bootable.
  • Make a bootable CUC image from a non bootable iso file, convert non-bootable iso image to bootable iso file.Download cisco cucm bootable iso fileDownload c.
  • Pada pembahasan sekarang kita menggunakan cisco CUCM versi 11.5(x), untuk mendapatkan file virtual machine template dan iso cucm bisa buka link berikut: Virtual Machine Template Cisco CUCM 11.5 Iso Cisco CUCM 11.5. Pertama kita login ke VMware Esxinya untuk menambahkan vm template cucm yang sudah kita download.
  • For the installation we are going to need two downloads from Cisco.com. The first is the OVA template and the second is the CUCM 11.5 ISO. The ISO is actually not bootable so you will need to make it bootable. I have a video on how to do that here.

Before you continue, be aware that this procedure is NOT approved by Cisco. Neither Cisco nor I will be responsible for any loss caused by this.

Click CUCM vm/Edit Settings/ click Options/Advanced/Boot Options We have 2 options there. Either increase “Power on Boot Delay: to 7000 or tick “Force BIOS Setup” Power on cucm vm connect BootableUCSInstallUCOS10.5.2.12901-1.sgn.iso.


Any bootable disc has to follow 'El Torito' specification. No exception for Cisco discs. The only difference between a bootable disc and non-bootable disc is the 'boot sector'. Thus the solution is very simple - extract the boot sector from a bootable disc and inject it into a non-bootable disc.
The boot sector is a very small file (usually less than 10k). And the boot sector is usually content independent (i.e. you may extract the boot sector from CUCM 7.1.3 and inject it into 7.1.5). You may save the boot sector on your USB thumb drive and keep it handy.
To extract/inject the boot sector, you need some disc image tools like UltraISO. (You may also use other ISO tools with similar features)
Step 1: Get the boot fileCucm
There are two ways to get a boot file - extract from the DVD's file system (regardless bootable or not) or extract from a bootable DVD's boot sector.Cucm 11.5 Iso
Option 1: Extract from DVD's file system (regardless bootable or not)
This option is preferred as you don't have to find another bootable disc or ISO file.Cucm
The boot file should be available on any CUCM DVD, regardless bootable or not. It is located in the 'isolinux' folder. File name is isolinux.bin.
Extract and save the isolinux.bin file to your hard drive. We'll need to use that later.
SerialOption 2: Extract the boot sector from a bootable DVD

If for some reason, you were not able to find/extract the isolinux.bin file, you may extract the boot file from a bootable disc (or ISO image).
Put a bootable CUCM disc into the DVD drive and launch UltraISO. Go to menu 'Bootable > Extract Boot File from CD/DVD...'
Save the file to your hard drive as a 'boot info file' (bif). In our example, we call it 'boot.bif'
Step 2: Inject the boot file
Open the non-bootable image in UltraISO. Go to menu 'Bootable'. Make sure 'Generate Bootinfotable' was checked

(it will NOT work without this option). Then choose 'Load Boot File...'.
Choose the boot file we saved before (isolinux.bin or boot.bif).

Now, you may go to 'File > Save As' to save the bootable image to an ISO file. Then you may burn the ISO to a disc with your favorite disc burner software.
