Problems with WXP installation.

[hecpok]

First of all, I am sorry for my bad English. I had problems installing Windows XP. I installed software "PLOP MANAGER 5.0.4." into a small hard disk of 20 GB without parting it. The menu appeared without problems with option USB. I inserted my 2GB pendrive into the USB conection and it showed the blue screen with the option to format my hard disk on the selected partition. But when I formatted the disk, then rebooted the computer and continued with installation, it suddenly stopped, showing the following mistake message : "I cannot find installation files". What can I do ?

Thanks very much for your help.
