Bloody heck, i fear i have destroyed everything. i will spare you the details, but basically. . is it possible to restore your comp with System Restore (on XP). . via dos?. . as i cant log in to windows (starts logging me out the instant it logs in) i created a dos boot disk on a working xp machine, booted with it on the broken machine, and can get a dos command screen up .what now? Or are there any other dos functions i could attempt in order to fix the problem? And also, (its a "Tiny" computer), the HDD has a special section of it (maybe even a seperate partition?) containing the OS in its original state, right? (or wrong) . .so can i some how restore the computer to its factory settings, by deleting everything other than the OS in its original state?. . i dont have a copy of Windows on CD, nor a reload CD thingy Bearing in mind that i cant get into windows, so all of this needs to be via dos . . i think . .well, i dont know, thats why im asking you lovely people help would be much appreciated. this isnt even my own computer which i have destroyed, so im panicking. .
