ubuntu uninstallation

Did you install Ubuntu with Wubi (from within Windows) or did you boot from the CD and repartition your disk, reducing your Windows XP partition? (It sounds like you did the latter and reduced your Windows partition to 3GB, but we need to clarify which it is.)

you can remove ubuntu deleting the partition and rezise the windows partition, but if you are goin to boot a restart again you dont can get into windows.

you have to format with windows cd.

but why windows, ubuntu is free and is of all.
