My only operational computer has shown some wierd signs like disapearing logs, rotated logs gone random files getting updated and so on.

Tho this is my only operational computer and I have decided to nuke it. My question is can I trust this system to download and burn my OS? If not what can I do to nuke this computer safely.

Get a trusted computer, download the ISO on there and use that as installation disk.

  • As I mentioned above that is the only operational computer I can use for now. What are the chances that something would actually infect the iso during the download or during the burn proccess?

  • It's very much possible. Jan 11, 2014 at 19:25
  • during the download I am not worried since I check the image with sha256 hashes but is it even possible to alter the image during the burn proccess?

  • @Nick It's possible even during the download. If your system has been compromised, it might report the expected sha256 hashes but corrupt the files. It's unlikely, but possible. Jan 11, 2014 at 19:39
  • If you only own one computer, try borrowing a friend's.

Maybe you have another trustworthy live system CD (such as knoppix) available. You can boot your computer from that CD, mount your filesystem in the live session, download and burn from within the live session. Then you can boot off the downloaded/burnt CD.
