Grub 1.99 loader drivemaping 2 HD issue.

[Wilscco]

Grub 1.99 loader drivemaping 2 HD issue.
Old desktop Intel 845, Pentiun 2.40, 2GB
2 Sata drives:
Hd0 with Windows Xp
Hd1 with Ubuntu 11.0

Bios booting default: Hd1 (where grub is installed)

Selecting Windows booting option sends error and Ctrl-Alt-Del reset message.

The old grub I had with OpenSuse was so simple, and drive switching-mapping worked so well with only two short code lines: map (Hd0) (hd1), map (Hd1) (hd0) for drives shifting
BUT now...

This code does not do the job for Windows Xp booting


Please help to fix the code, so mapping works and I don't have to get into BIOS to change default HD.
Thanks in advance. Wilscco

You shouldn't have to be doing this by hand.

Instead, boot into Ubuntu, open a terminal and enter "sudo update-grub". That will regenerate the default GRUB config file -- and the new one should point properly to the Windows partition.

If Windows still does not start after a reboot and OS selection, then remove the Ubuntu drive and confirm that the Windows drive will boot into the desktop on its own.

Mark thanks for your answer. But it just did not work.
Sata HD with windowsXp partitions boots fine by itself. Either leaving or removing the second sata HD with the Ubuntu 11.10 system and grub. The update via "sudo update-grub " added a new line to grub with previous system option. the WindowsXp option code remain unchanged and same error occurs
