Thanks for the response.
I had googled it, that's how I found this forum and image burn - I've now uninstalled nero and the like .
The vista recovery image is 123,392kb in size. It is indeed bootable and inside the root\boot folder it has 3 files: bcd at 256kb, boot.sdi at 3,096kb and bootfix.bin.
In root\sources it has boot.wim at 119,106kb and in the root of the cd it has bootmgr at 325kb.
Thats all the files and folders it has.
