ok. Thank you very much. On 11/28/06, Andrei E. Warkentin <[EMAIL PROTECTED]> wrote:
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.
