Hello, a friend of mine accidentally deleted an important file from his sys32 folder, and now they system will not boot. I placed the disc into the drive to try to reinstall and booted from the disc. As the disc finished loading, the status bar at the bottom read "starting up windows" or something of that nature. immediately I got the blue Stop error screen with the following error message Stop: 0x000007E (0xc0000005, 0xf53e0bf, 0xf898a208 0xf8989f08) Pci.sys- Address f853e0bf base at f8537000, datestamp 3b7d855c There is nothing to do after this screen but restart it, and I do not know what else I can possibly do to fix this computer. If anybody has any information it would be greatly appreciated. I searched this on th microsoft website and it came up with no results!
