Ghost 15 - Bootable Restore CD/DVD

Hi, Been several years since I used Ghost and have just purchased v15.

 

I want to create an image file of a PC onto a CD/DVD so that if my PC disk fails I can replace the disk, insert the CD/DVD, boot from the disc and restore the entire hard drive (which will need additional updating of course).

 

Is Ghost 15 able to do this? I have tested using the One Time Backup Wizard which has taken up 4 DVD's none of which appear bootable (just over 2 hours to create for 20GB of data).

 

Questions:

Should I have created the Symantec Recovery Disc (SRD) instead?

What will the SRD allow me to do (restore all my programmes and files)?

 

thanks
