Help with IBM personal Computer,recovery disk

[Maven13]

When trying to wipe clean the hard drive,the recovery disk prompts me to type agree,then hit enter,and it then says it has received a bad command,after it commands you to do what you just did.
Got the trojan from hell, and now I just want to install Windows XP, but when trying to install,it copies the windows ,and now...there is no room left for error.
Please help me?

What OS did the computer originally come with?

Use a boot diskette to wipe the hard drive.

Reinstall windows, it pretty much destroys anything on
the MBR.
