Fault 1: MBR fault
Fault performance: similar to "ldf; press F11 start to system restore" after booting. Error message
Cause analysis: Many software such as one-click Ghost, in order to achieve the purpose of priority startup, install The hard disk MBR is often modified, so that the corresponding boot menu information will appear at boot time, but if such software is defective or incompatible with Win7, it will easily lead to Win7 not starting properly.
Workaround: For the repair operation of the hard disk master boot record (MBR), you can easily solve this fault by using the repair tool ——Bootrec.exe that comes with the Win7 installation CD. The specific steps are as follows: first start the computer with the Win7 installation CD, when the CD is booted, press Shift+F10, call up the command prompt window and enter the DOS command “bootrec /fixmbr” (see Figure 1), then Press the Enter key and follow the prompts to complete the rewrite operation of the hard disk master boot record.

Fault 2: Oxc000000e fault
Fault performance: The system cannot log in to the system normally when booting, but directly pops up the Oxc000000e fault prompt shown in Figure 2.
Cause analysis: Due to the installation or uninstallation of some special software, it often causes very serious damage to the Win7 boot program, so Win7 will have Oxc000000e error when starting, which will not start the system properly. In this case, pressing the F8 shortcut will not bring up the Win7 advanced boot menu, and of course it will not be able to perform the repair operation in safe mode.

Solution: The following five DOS commands are executed in sequence at the cursor position of the window shown in Figure 1. (Figure 3, C drive is the system disk installed by Win7, the same below): Br>c:
cd windowssystem32
bcdedit /set {default} osdevice boot
bcdedit /set {default} device boot
bcdedit /set {default} detecthal 1
Tips: If You don't have a Win7 installation CD, you can also enter the above five DOS commands in the WinPE environment.

Fault 3: BOOTMGR is missing error when booting
Fault performance: Whenever booting, the error message shown in Figure 4 will appear, and the system will not log in normally. . The error message, translated into Chinese is Bootmgr lost, press Ctrl+Alt+Del to restart.
▲图4
Cause analysis: The cause of this startup failure, or because the Bootmgr file is indeed lost, this is the most common; another possibility is due to disk errors.
Workaround: If the Bootmgr file is missing, you can use the method of rebuilding the Win7 boot file to solve the problem. The operation steps are as follows: execute the following two DOS commands in the cursor position of the window shown in Figure 1:
C:
bcdboot C:windows /s C:
Then restart the system, you can see Win7 The familiar boot menu, and then select the first Win7 menu option, after some initialization, we can use Win7 system normally.
If you still can't solve the problem after the above steps, then the fault is probably caused by the disk error. At this time, you can try to run the chkdsk /f command in WinPE environment. The fault can be well obtained. solve.
Failure 4: BOOTMGR is compressed error when booting
Fault performance: This fault is similar to “BOOTMGR is missing”, which is also the same as booting and cannot log in to the system but only “BOOTMGR is compressed” error message ( As shown in Figure 5).
▲图5
Cause analysis: The cause of this failure is caused by the compression of the system disk.
Workaround: Start the system with WinPE, run its own command prompt tool and execute the following DOS commands in sequence:
c:
cd windowssystem32
compact /u /a /f /i /Sc:*
After executing the above DOS command, the command prompt tool will start the full decompression of the C disk file, and then restart the system, you can log in to the Win7 system.
