To calculate the MD5 checksum, you have run the md5sum tool with the filename as parameter:
md5sum ubuntu-12.04-alternate-i386.iso

abraham@abraham-laptop:~$ md5sum ubuntu-12.04-alternate-i386.iso
md5sum: ubuntu-12.04-alternate-i386.iso: No such file or directory
abraham@abraham-laptop:~$

You should make sure that the file is actually in that folder. If not you will have to change to that folder first or give the full path to the file.

Also: checking the MD5 sum ist not a required step. It only checks if the file was download properly. You can skip that.

Then run:

md5sum $HOME/ubuntu-12.04-alternate-i386.iso

The file is not a command, so trying to run it with sudo (or even without) makes no sense at all.

Hello Thomas,
thank you for your help. The reason it didnt do the md5 test ws That I had only downloaded but not done the extraction.Having done the extraction and by passing md5 I am in unebootin and the process is well under way
thanks

You don't extract the file for any of the possible installation methods, just because your Windows OS gives it a WinRAR icon does NOT mean it is to be extracted.
