I have Windows 2003 installed in C and Win XP in D......Then I formatted C and installed Windows 7, but after that I am not able to boot Win XP...... I have tried BCDEDIT & EasyBCD but didnt work for me..... And later I realized there are no files in D to boot Win XP( ie, boot.ini, ntldr, ntdetect etc)...... I copied all required Windows booting files from other system to D drive and I edited Windows 7 boot with BCDEDIT to point NTLDR on D drive...... Then I was getting error like,Invalid boot.in filebooting from C:\WindowsNTDETECT.COM Failed.....Plz help me to find the solution..Thanks
