win7 ubuntu 双系统启动选项DIY.doc

Win7 ubuntu双系统启动选项DIY本文由本人原创，各位爱好Linu的好友，若要转载，请注明出处，如有不明之处，请用QQ:334245938联系我。一、问题：分别安装完Win7与ubuntu12.04后，发现启动选项显示太多，如何在启动计算机启动后，只显示win7与ubuntu系统两条选项，使计算机的启动选项更加的简洁呢？二、改决方法：1、运行计算机的左上角“DASH主页”启动器，在框中输入终端命令符“terminal”,点终端图标即可自动进入mmmm-slsj:$(注：绿色字是你们的计算机的名称），在命令行输sudo -i，些时屏幕显示sudo password for mm:在此处输入你的安装ubuntu时密码，些时屏幕显示rootmm-slsj:#2、在命令行输入：gedit /boot/grub/grub.cfg，进入 boot/grub/grub.cfg的编辑，把原文按以下内容改好后，保存，退出。3、重启计算机。ok！你的计算机已经是双系统的简洁启动界面了，只显示win 7系统与Linuxubuntu 系统两条选项，默认第一选项是win7系统，第二选项是ubuntuu系统，Linux ubuntu 系统选项的下一级菜单下可选ubuntu系统的其他选项。4、grub多系统管理器的编辑成果。# DO NOT EDIT THIS FILE# It is automatically generated bny grub-mkconfig using templates# from /etc/grub.d and settings from /etc/default/grub# BEGIN /etc/grub.d/00_header #if -s $prefix/grubenv ;
