This is well discussed (examples at http://www.google.com/search?hl=en&q=XP+Uninstalling+Ubuntu+WUBILDR
But if this was mine I would delete the line with wubildr from the boot.ini.
I recently installed Ubuntu 9.04 and want to delete it out of my computer. I Installed into windows xp. So i went to add/remove progs and uninstalled it. but when i restart my computer i get to the boot screen an have chose from xp or ubuntu? why is this? please help. I have partitioned 5 Gb for ubuntu how can I get it back and use it for xp? can i got to the file "boot.ini" found in C drive and erase the text where it says 'C:\wubildr.mbr = "Ubuntu"' and change the value of partition from 1 to 0 in that file? will this help ? or is there a better way?
