So I wiped my hard drive and now want to reinstall Windows XP Professional from my installation disc, but my disc just kicks me into PC DOS prompting me for input from the A:\ drive. Trying to install from the genuine SP2 CD gives me errors before it even finishes loading the installation files. My computer is a Compaq Presario, AMD 32-bit Sempron, 768mb RAM. Ever since I backed up my files and had two failed wipe attempt using first DBAN and then HD Shredder Home Edition noting has really been working. Any help from anyone would be greatly appreciated.
