Freeware Recovery?

[tehjimsta]

Well, since nobody really helped me out on my other thread, and it'd probably be considered grave digging if posted there, this is my new thread. This time, instead of being so specific, I'll just generalize the category of software I need. Teknicalissue's killer batch isn't just named killer, it really WILL kill! Here's the features I absolutely NEED for my recovery from the killer batch:

-must be well-known or freeware
-must be self-bootable
-must have reliable recovery of files
-must have a command prompt
-must have something like windows explorer built in

And these are optional:

-be able to display all changes made to a file
-be able to simply restore your computer like windows restore, but includes files
-be able to be installed on linux
-is smaller than *00 MB

Please help! Thanks in advance, and all help is appreciated. Make sure you tell me if it has any of my preferred features or if it is missing any of my required ones.

Note to teknicalissue: Help me out! >_> Oh, and if the files deleted and changed really were the same for each and every computer with no modifications normally there, then please give me the package of system files...
