Windows and Ubuntu are enabled by default.

Because too many times of updating the kernel of UbuntuLinux are involved, the startup information of multiple kernels is included in the file. So simply put WindowsXP to the first position, because the first one is started by default. Under setdefault = "0" is the/etc/grub. cfg # DONOTEDITTHISFILE # Itisautomaticallygenerated of Ubuntu10.04 on my desktop

Because the Ubuntu Linux kernel has been updated too many times, the startup information of many kernels is in the file.

So simply put Windows XP in the first place, because

The first one is started by default.
