Shouldn't have done that. I'm assuming "sys" here is from Win9X or DOS.
The bootsector provided by NT looks for a file in the root of the partition called "ntldr", which in turn looks for "boot.ini" "
ntdetect.com", and (obviously) ntoskrnl.exe and the initial drivers loaded.
Basically, if you didn't "sys a: c:", it would have worked just fine (the way you chainload from grub looks right). But you overwrote the NT bootsector with a DOS/Win9X one that looks for
io.sys/msdos.sys. Go boot from a Windows installation disk and tell it to repair your system.

Hi ,Coly:
Thank you for your answer.
I have used the command
sys a: c:
then when I boot from the harddisk, an error occure "missing operation system"
Then I boot from my flash disk and enter the grub
grub>root (hd0,0)
grub>makeactive
grub>chainloader +1
grub>boot
then I entered the DOS.
How can I load the ntldr?

this will help you to boot the xp. BTW, maybe you need to re-install the
grub in your ubuntu.
