I took my hard drive out of my old computer and stuck it in my newer one. Took my brother's hard drive out of his computer and stuck it in my old one because it was faster than his. Now it will not boot up it goes to this screen: I've selected all the options and all it does is reboot and go to the same screen. I can't reinstall because it didn't come with software. I don't remember were I put the recovery discs I had to make either. I didn't change the jumper setting on the hard drive. My old computer is similar to his just a different model and newer than his, both are Compaq Presario SR1303WM (my brother's) and SR141NX (my old one). Please help, I didn't back up any of his files. Only thing he had on there were pictures but still they were pictures from his vacation and other outings.
