If Windows will not boot correctly. For instance, a blinking cursor shows up and after a few seconds the computer reboots itself and continues the same process in an infinite loop.

The problem can occur when re-imaging the disk which may cause issues previously installed Linux partitions, and with the GRUB bootloader.

Assuming that the Linux partition is no longer needed…

To fix the problem and have it boot straight into windows (without using GRUB).

• Create and use a “Windows Repair Disk” and boot from that repair disk.
• Follow the instructions from the disk and do all the startup repairs.
• Finally you need to get into the command prompt which is an option in the repair disk and run the following commands.

  bootrec.exe /FixMbr
  bootrec.exe /FixBoot 
  bootrec.exe /RebuildBcd

• Reset the computer and it should now boot straight into windows without any problems. Since this was formerly a dual boot, what do I do with the left over space which use to be used for Ubuntu? Use GParted to resize and append the left over space back to my windows partition.
