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

        The computer is pre-installed with Win7 system, which is very good for work and entertainment. Sometimes, the development program needs to use the server function system. For this reason, Server2008 is installed, and the installation part runs normally. After installing Office2007 and LiveServices, only a small amount is left. The program was not installed and a small number of devices were not configured. At this point, I started importing 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 displays the error message "Cannot find boot device". The case this time on the ignorant, how to solve it head first reaction?

First, the author disappears before instruction in the CD waiting to start unsuccessful, will try to use the F8 key. Then you will select "Repair 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 view these details, the command prompt must be given together with the Run as Admimistrator. Equipment

BootMgr from a call option is D: drive - that is, the author of the external eSATA drive. 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, author input: bcdedit /exportc: filename to extract a backup of bootmgr. 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 in the internal driver of the computer and the external eSATA driver.

Finally, shut down the system, and disconnect the external drive eSATA connection. 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.

currently WindowsServer2008 and the upcoming release of Windows7 has become the focus of security concerns, so companies are (especially those businesses still using XP system) should consider deploying this combination as soon as possible, but be aware that the dual system prone The problem, for this reason, pay special attention to certain considerations when using these two systems.
