Now I am using Windows XP Pro.O.S.(with SP2) but due to the programs on Linux which could be downloaded for free form internet need for Linux occured.
I downloaded Suse 10 and I started reading Linux forums, and I realized that there are a lot of problems using dual O.S (Linux+Windows). There are a lot of posts from people who make their previous (Windows) O.S. break and loose data and programs they already had. I concluded that there is a great risk installing Linux on my HD with Windows already installed (at least for me who never used or installed Linux O.S. before).
I purchased one 2.5 inch HD and case, so I can connect it with my laptop via USB 2.0 port. Now, I want to install SUSE 10 on this external USB HD. My Laptop (IBM T40) supports USB boot but I have red that there is a problem that some Linux installing software do not recognize external USB HD. There is also a problem (from forums) that some people by accident installed some of Linux O.S. componets on internal HD and their Windows, normally, crashed.
I wanted to be sure that nothing from my old HD is lost and I simply physically replaced my old HD with new one (now there is not possibility that anything form old Windows HD will be ruined). I normally installed SUSE 10 and everything worked fine. But, when I put my new Linux HD in case, returned my old HD, restart system with USB (with my linux HD) boot as primary boot, SUSE did not want to boot...
This is obviously the wrong way of safely installing Linux...
Now, how can I make SUSE 10 boot from my external USB HD ???
P.S. Windows XP HD still works fine
