Making a button link to another page

I'm trying to make a button link to another page, it worked in IE6, but when I tried it in Firefox, it couldn't find the page even though the address was right. The website is currently on a memory stick. Here is a sample of my code:

<a href="WellerWorld/Pages/linux/index.htm"><input type="button" value="My Linux Website"></a>

Any help would be much appreciated.

<input type="button" value="My Linux Website" onclick="location.href='WellerWorld/Pages/linux/index.htm'" />
