Vista OS disk for Gateway used to install on another Laptop

Is it possible to use a Vista OS cd for a Gateway laptop to install Vista on another Laptop? I wish to do this since the other Laptop didn't come with an OS cd, and recently I had to completely replace the corrupted Vista with Ubuntu I now need to reinstall Vista but only have my Vista disk for my Gateway laptop.

Maybe. If you have the Vista key for this computer in particular, a OS install should be possible for any type of CD. You´ve to try it to know for sure if yours CD works. I sucessfully installed with OEM install cd´s in diferent computers (Dell Notebook, Dell Workstation, HP). But none were Vista. The last one was XP SP2.

Talvez. Se você tiver a chave de registro do Vista para este computador em particular, a instalação do S.O. deveria ser possível para qualquer tipo de CD. Você tem que tentar a instalação para ter certeza. Eu instalei com sucesso usando cd´s de instalação OEM em diferentes computadores (Notebook Dell, Estação de Trabalho Dell, Notebook HP). Mas nenhum deles era Vista. O último era XP SP2.

No, most OEM install cd's are made only for that specific computer model and will only work with that computer.
