just make a new boot.ini with this text :
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Professional" /noexecute=optin /fastdetect
after this save the file as type "all files" and name it boot.ini (save it in my docs) then go to c: and enable viewing of hidden files and folders. and also both the option below as hide protected system files and the other one too.. now if you have a boot.ini in C: then open it and delete anything written in it .. now copy the text which i wrote above and save the file (YOU WILL ALSO HAVE TO REMOVE READ ONLY ATTRIB. OF THE FILE FIRST)
IF YOU find no file in c: then copy the file you saved in MY DOCS there and change its attrib to read only ..
YOUR SYSTEM WILL BOOT OK now
