Thanks for your answer.
The software I’m trying to install are from the spanish goverment, they have linux versions that run on Ubuntu directly or using wine, I’m trying to install them on SUSE and I can’t. Those kind of applications are not in the Open Build Service. By the way, I don’t know how to look for applications in the servers for SUSE. My main concern is that I need to install some of those applications for tomorrow, that’s why I want to install ubuntu but I don’t have a CD or DVD with SUSE desktop software (I bought the laptop yesterday but in the box there were only the warranty document from HP and the laptop itself, but nothing else). In the shop, they’ve told me that I should have a way to recover the system installed in the computer by the manufacturer (HP), if not, I could lose the warranty on the product.
I must apologize again about my lack of knowledge… I don’t know how to execute the command zypper or how to use dd (I’m not a big help).
Is it possible to install Ubuntu on Suse and keep the original system? I’d like to know to learn how to use it, but now I need to install those programs urgently.
