You do the Cisco Collaboration Project students should know that the current Cisco official website can not download with a bootable installation image, then how to do it, the way is there, according to my experience I summed up the following several methods, for your reference:
Method One:
1. Extracting an existing version of a bootable file
2. Download the appropriate version of the installation image from Cisco (not bootable)
3. Use the UltraISO or magic ISO maker software to associate the bootable seed file with the installation image, making it a bootable installation image, and search by yourself;
There may be a problem with this method:
1. Using tools such as UltraISO to make bootable installation files may cause the original image to be unavailable;
2. Using tools such as UltraISO to make bootable installation files, the original installation image of the MD5 checksum will be lost, but does not affect the installation;
Method Two:
1. A bootable installation image is available, and a non-bootable installation image is downloaded from Cisco;
2. Directly using the above installation image installation system, so that it through the hardware and other related detection;
3. When the Media check page appears, remove the original disc and mount the non-bootable installation image;
4. Continue the installation;
The above two methods are only for reference, in fact, there are several, but the use of more and useful is the above method; Thank you!
