I just shut down my dual boot by reformatting the Linux partition and running Ubuntu in a virtual machine instead. This is the walkthrough:
1.) Reformat the Linux partition to NTFS with the Windows partitioner tool (don’t forget to backup any important work first!).
2.) Restart with your windows cd and use the repair tool by using the ‘R’ option. Use the commands ‘fixboot’ and ‘fixmbr’ with no options to get rid of the GRUB dual boot.
3.) Install VMWare workstation.
