bear with me but: I'm trying to download Ubuntu to dual-boot with XP. Think of me as your Grandad! Have used Wubi from Canonical and loaded to my 'downloads' folder. Next step is to 'Verify' by running 'Echo etc.' - question is How?. Have placed file in 'Downloads' and run via CMD but all I get is 'shasum is not recognized as an internal or external command etc. So how do I 'run' it plse?

Again - be gentle and use Olde English.

Saturday now - I take it that nobody can talk me through the process of running the verifier then?

The 'How do I install Ubuntu' thread is of no use at all as it doesn't even mention verifying the downloaded file (section 2) - let alone how.

As some of the comments have noted, Wubi is really no longer in use. Instead, you should consider downloading a recent Ubuntu ISO file from https://ubuntu.com/download/desktop. When you reach the actual download page, you will see a link to "Verify your download". This will display the SHA256 checksum for the downloaded ISO file. Since you are using Windows, a simple way to verify the downloaded file is to use the MD5 & SHA Checksum Utility (https://raylin.wordpress.com/downloads/md5-sha-1-checksum-utility/). Running this program displays a window that lets you browse to the location of the downloaded ISO file, copy the SHA256 checksum obtained above, and automatically verify the latter against the checksum generated for the downloaded file.
