Tonight, I tried to install ManDrake Linux 10.0 by using 3 installation discs on a reboot.... During the installation, the computer froze and I had to restart it. Now, I can not format and install either... Prior to the installation, I had Windows XP. My computer is a Dell 9100, P4 3.0 w/ HT, 512 RAM, 40 GB HD, Radeon 64MB. When I insert the XP setup CD and attempt to reinstall, it prepares to setup, however it then switches to the blue screen of death and says "c0000221 unknown hard error systemroot/system32/ntdll.dll" Please, someone help me with this, I have no idea of what to do!
