I have tried to email the Acronis files to kestrel but one file is too big, it is over my 15Mb limit.
Anyway to run Linux from a USB pendrive you will need to download it for free from the official Linux site and install it on a USB stick. All instructions are on the Linux site.
Download | Ubuntu
There is no need to install Linux if you want to look at what's on the PC, just run the sample program and it will do everything except install. When you shut down and take the stick out Windows will start as normal.
I have used it in the past only to gain more experience of Linux but I went back to Windows.
