Problem installing Windows XP Pro digital signatures

Hello everybody!

I am trying to install xp pro on a Compaq Presario C700, when finished copying files, nothing more to install, get an error message saying that this is a serious error that can not install the catalog of digital signatures sp2.cat. With another cd of xp not a lot of copying files and thought it was the CD, with versions such as Colossus also gave me errors, but now is with a xp pro ordinary. In addition, I have not encountered these error messages or by any thread of this forum or none.

Has anyone seen something like this?

As you mention in your post, I get the idea that in all cases (as in the Colossus) are illegal copies of windows, that's exactly what you risk when you work with them, to generate errors that seem to come out of nowhere.

Hello,

I have also been tested with other OS, but also hackers who until now had not given me any problems. I thought that it was best for the hard disk controller, which in addition to downplay the native mode of the SATA Bios, I had to put the driver with F6 once it starts, but I can not find the driver for that model, and models like I did not recognize them.

Question:
-I am putting the driver of similar models from HP via USB or does that can be q that's why I do not recognize?
-What has happened with the Compaq Presario C700?
