Hi,

What's the comma= nd you use in grub legacy ?

BTW, you should know that device number = of grub2 is not the same as
grub legacy, the first partition is (hd0,1) = instead of (hd0,0).
Anyway, you can use ls to list the current devices.<= BR>

Hi,

The partition number= difference I am aware of.That difference was taken into account.

In the case of grub legacy,the grub.cfg was in this way.

menuentry "Windows" {

rootnoverify=0A

}

As windows is in the 3 par= tition, using ls (hd0,3) I could see windows files.

I am not sure wheth= er this is a filesystem issue (ntfs) which grub2 is not able to identify as= such (or) Grub2 is not able to read the boot sector correctly.( As  l= egacy grub was able to boot quite easily the same thing)

I am badly stuck and I dont want to go back to legacy grub also.
