Re: REMOVE OPtion from WIndows Boot Manager (nothing works)
Lets go one step back.
You had a dual boot of 11.10 and WinXP.
Next you installed Win7 over WinXP.
Next you installed 11.04 inside Win7.
You removed Ubuntu using disk management.
If so, step 2 removed grub from the MBR and you could only boot windows. That's good.
Next step 4 removed your old 11.10 partition(s); it did NOT remove your wubi installation.
What's left is Win7 with a functional wubi installation. I'm not a wubi man. What happens when you try to boot Ubuntu? still working?
If you don't make backups of your important data, your data is obviously not important to you.
