Experts share the secret of repairing Win7 and win2008 dual system error

Computer pre-installed win7 system, usually work and entertainment use is very good, but sometimes the development program needs to use the server function system, for this purpose installed Server2008, the installation part It works fine; after installing Office 2007 and Live Services, only a small number of programs are not installed and a small number of devices are not configured. At this point, I start to import old data. The reason why the author did not immediately realize the problem is because the author first started to reload the backup data. When the author installs the DVD, the system pops up the error message "The boot device could not be found". At this time, I am embarrassed, how to solve the first reaction of the head?

First of all, the author used to use the F8 key when the CD command disappeared and waited for the unsuccessful start. Then you will select “fix my system> and <;start repair", Windows will find the crux. This time, although I replaced the installation DVD, I chose the same steps as above and got the same result. It just needs some command prompts and gives some startup configuration data editors (BCDEDIT) that can see which parts are being used as startup.

To see these details, the command prompt must be given along with Run as an Admimistrator.

BootMgr calls the device from the option D: driver —— which is the author's external eSATA driver. In order to edit its value, the author enters: bcdedit/set{bootmgr} device “partition=C:” I am sure that the C: driver contains the bootmgr that the D: driver used. However, this does not help much in solving the problem.

Next, I will extract the bootmgr backup by typing: bcdedit/export c: \\filename. Then, restart the computer from the DVD device and select “Repair System”. Then choose to go to the command prompt and delete the bootmgr.efi file from both the internal drive of the computer and the external eSATA driver.

Finally, shut down the system and disconnect the external eSATA driver. Then turn on the power and boot from the DVD device. I chose "Repair System", and when the automated process scans for Windows installation, it immediately finds the problem with the startup and recommends fixing it. The author agrees with the system's repair suggestions and restarts the computer without an external eSATA drive and DVD device. So it succeeded.

At present, Windows Server 2008 and the upcoming release of Windows 7 have become the focus of security, so companies (especially those still using XP) should consider deploying this combination as early as possible, but pay attention to the double The system is prone to problems, so pay special attention to certain considerations when using these two systems.
