I need help immediately. I bought a new computer. It came installed with windows 7. I want to install xp. But whenever I boot from cd it shows an error. Windows encountered an error and set up needs to shut down. Check your hard disk for virus and corruption. Check if hard disk is configured properly. Uninstall any newly added hard disk. There are no viruses in my system. Kindly help me. Thanks in advance.
First thing first: If your machine has came preinstalled with Windows 7, then it must be a Genuine licensed version. And if you are installing XP over it, it would most probably be Pirated.
Q: Now, do you
REALLY want to lose a
GENUINE LATEST VERSION of Windows with a
DECADE OLD pirated Windows?
If answer to above question is Yes, then try SAM's method.
And if the disk is correct, try to Nuke Hard drive from s/w like, Darik's Boot And Nuke | Hard Drive Disk Wipe and Data Clearing And then try to install XP.
