I recently purchased a Dell Vostro notebook with Ubuntu Netbook edition 10.04 pre-installed. I tried adding a partition and installed Windows XP but it didn't work out due to too many partitions in the system already.
Now I have restored the laptop to factory setting using Dell Utility partition and the Windows partition is completely deleted, however my grub2 still shows Windows on /dev/sda2
Microsoft Windows XP Professional (on /dev/sda2)
Any ideas how to remove it from grub? I know I can remove /etc/grub.d/30_os-probe but I am more interested in why os-probe is showing the deleted partition.
