安装完Ubuntu后系统就用grub接管了Windows7的启动选项,但哪天不想用Ubuntu了,除了用wubi安装能够吃后悔药外,用Windows7的安装盘修复只需要一个命令,一眨眼的功夫就能正常用Windows7单启动了。
无论Ubuntu分区是否已经删除,开机出现grub>字符无法启动系统,或者Ubuntu还呆在它的ext4分区中,直接用Windows7光盘启动系统,然后照一下步骤:
1、用Windows7光盘启动系统后会让你选择语言,默认的或者自己随便选一下后按下一步;
2、在下一个界面会提示安装Windows,此时选择左下角的修复计算机;
3、等待系统找到Windows7系统后按下一步;
4、选择最后一个“Command Prompt”;
5、在弹出的命令行对话框中输入“bootrec.exe[空格]/fixmbr”,按下回车后就已经删除了grub,很快。。
退出光盘重启计算机后系统就已经自动进入Windows7了
bootrec.exe 的其他参数:
* /FixMbr. Re-writes the master boot record (MBR) of the system partition to start Windows Vista. This won’t overwrite the existing partition table.
* /FixBoot. Writes a boot sector onto the system partition to start Windows Vista.
* /ScanOs. Scans all disks for Windows Vista installations and displays them to you. Oddly, this didn’t work for me, even on a test system that was starting just fine.
* /RebuildBcd. Scans all disks for Windows Vista installations and prompts you to pick the ones you want to add to the BCD.
