From the looks of your fdisk and menu.lst, you must have changed things around a bit when you reinstalled winxp. In particular, it looks like winxp was originally installed on the first primary partition on your hard drive, sda1. However, on reinstall, either you or the windows installer decided to create an extended/logical partition, sda5, with sda1 as the container and install winxp there. Try changing your windows entry in menu.lst to:
Code:
title Microsoft Windows XP Professional
root (hd0,6)
savedefault
makeactive
chainloader +1
To see your new windows partition in ubuntu you will need to edit your /etc/fstab line changing the sda1 entry to sda5.
It is the installer that fails to deliver a correct booting choice for Windows. Nothing wrong with the existing system.
Try this, when see Ubuntu booting screen instead of choosing a system to boot just press the "c" key to get a Grub prompt.
You should be able to boot up Windows manually by these commands
Code:
root (hd0,3)
makeactive
chainloader +1
boot
If the above works amend the /boot/grub/menu.lst for Windows as follow
Code:
title Microsoft Windows XP Professional
root (hd0,3)
chainloader +1
Once you make (hd0,3), which is sda4 in Linux term, "active" (bootable in Linux term) it should remain active forever unless a stupid installer changes it.
You have sda4 and sda5 MS partitions. XP always dumps the boot loader in the first partition it detected so the Windows boot loader NTLDR should be in sda4. Sda5 is the XP partition but it should have no boot loader of its own inside. XP cannot boot itself from a logical partition and relies on a boot loader in a primary partition to pull it up. Therefore it has to be sda4.
Lastly after you know how to boot a Linux manually please type this command in a Grub prompt
Code:
geometry (hd0)
If you can see partition (3) and (4) displayed and they have partition type b for fat32 and 7 for ntfs then Grub proves to you that it "can" see Windows.
Since you have told the world "Grub can't see Windows" I gather you own Grub a apology. Fair?
