Into the recovery console input FIXBOOT the system will prompt you sure you want to write new boot sector to the target disk partition according to Y, then press enter after the success of the writing system according to the EXIT to restart. If still won't do is likely to be the master Boot Record MBR the Main Boot Record damaged at this time we are going to use you this command but the command the risk is too big may damage the partition information data loss so don't use until the end Using methods like FIXBOOT input into the recovery console you the system will have a warning message determined to perform press Y and then press enter to then recovery console prompt state press EXIT to restart. (2) the system boot file damage or loss When the system starts tip can't find the NTLDR restart or NTDETECT.COM the system requirements.

In fact the two files can be found in the installation CD i386 directory packing directly copied to the system directory. First enter the recovery console then enter assumes that the disc drive is D dish "COPY D: \ \ i386 \ \ NTLDR C: \ \" or "COPY D:\\i386\\NTDETECT.COM C: \ \" such as tips can file exists cover then knocked at the EXIT to restart.

Enter the recovery console and then into the i386 folder of the disc first to make sure we are missing files compressed. If there is no compressed we directly copied to the target location is ok ok. such as NTDLL DLL if will use EXPAND command is compressed such as NTDSBCLI. DL_ last as long as the suffix is underlined is compressed . COPY of the format is COPY Spaces Spaces source file target folder For example COPY D: \ \ i386 \ \ NTDLL DLL C: \ \ Windows \ \ System32 EXPAND format EXPAND Spaces Spaces source file target folder For example EXPAND D: \ \ i386 \ \ NTDSBCLI DL_ C: \ \ Windows \ \ System32 reading recovery console using tutorial Windows XP system Finally couldn't solve the if through recovery console also then you can buy a Windows PE system PE to important documents copy CD start reshipment system at last
