双启动Windows 8& Windows 7的 [英] Dual boot Windows 8 & Windows 7

问题描述

我使用bcdedit / copy {current} -d" Windows 7"

制作副本，并将设备+ osdevice设置为指向我的Windows 7卷。

在下次重启时，有一个选项可以选择应该加载的操作系统，

但是启动几乎整个Windows 8后。

当我选择Windows 7时，机器完全重新启动并启动Windows 7.

这样我们就会在整个Windows 8启动过程中浪费时间  +重新启动。

 

是否有更有效的方法在启动时选择操作系统（不加载太多Windows 8）？

bootmgr（win7）和&之间的二进制文件比较。 bootmgr（win8）显示了很多差异。

解决方案

是的，安装自己的bootloader。 我写了一个类似的答案给另一个用户问同样的事情，这是我给他的指示：

 

步骤1：插入Windows 7恢复盘并等待它启动进入

步骤2：点击"修复我的电脑"。磁盘启动后

步骤3：点击更多选项，然后命令提示符

步骤4：输入命令提示符：bootrec then，键入bootrec \ fix MBR

步骤5：在命令提示符下键入exit或单击其上的x将其关闭

步骤6：重新启动PC ，它可能会默认启动到Windows 7，而不是然后向您提供启动选项，然后，当它启动时，应该从Windows使用第三方启动管理器（我个人最喜欢的是EasyBCD）

STEP 7：重新启动一旦启动管理器设置已经应用

步骤8：如果不成功则重复步骤1-7

  ;

希望有所帮助，Windows 8上的引导程序是为了简单起见，但是，请记住，这不是最终版本，并且会有更多的改进及时到来。

I made a copy with bcdedit /copy {current} -d "Windows 7"

and set the device + osdevice pointing to my Windows 7 volume.

At the next reboot there's an option to choose the OS that should be loaded,

but AFTER booting up nearly the whole Windows 8.

When I select Windows 7 the machine reboots completely and start Windows 7.

That way we're loosing time with the whole Windows 8 boot process + the reboot.

 

Is there a more effective way to select the OS at Startup (without loading so much Windows 8)?

A binary filecompare between bootmgr(win7) & bootmgr(win8) shows a lot of differences.

解决方案

yes, install your own bootloader.  I wrote a similar answer to another user asking the same thing and here are the instructions I gave him:

 

STEP 1: insert your windows 7 recovery disk and wait for it to boot into it

STEP 2: hit "repair my computer" once the disk has booted

STEP 3: hit more options, then command prompt

STEP 4: type in command prompt: bootrec then, type bootrec\fix MBR

STEP 5: type exit in the command prompt or click the x on it to close it

STEP 6: reboot your PC, it MIGHT boot into windows 7 by default rather then presenting you with the option to boot however, it is then when you should use a 3rd party boot manager (my personal favorite is EasyBCD) from windows once it boots

STEP 7: reboot once the boot manager settings have been applied

STEP 8: repeat steps 1-7 if unsuccessful

 

Hope that helped a little, the bootloader on windows 8 was made for simplicity, but, remember, this isn't the final release and that more improvements will come in time.
