Windows XP is missing after I installed the new operating system Windows 8.
This article will help you find Windows XP back to the operatiing system selection menu.
1. Run cmd as administrator and type these commands
bcdedit /create {ntldr} /d "WINDOWS XP"
bcdedit /set {ntldr} device partition=C:
bcdedit /set {ntldr} path \ntldr
bcdedit /displayorder {ntldr} /addlast
bcdedit /timeout 10
2. Copy 4 files from Windows XP system disk root to the Windows 8 system disk root
boot.ini
bootfont.bin
NTDETECT.COM
ntldr
3. Have fun!
