WinXP installation failure alternative solution

The author's computer installed Windows XP system, because the use of too long running speed began to slow down, so I have to format the C drive to reinstall Windows XP. First boot into the original DOS state with the CD, format the C drive with the Format command. Then restart the WinXP installation disk into the CD-ROM drive and start installing the system. The first step is to copy the windows file to the hard disk, and the prompt will automatically restart after the copy is completed. Everything looks very normal, but there is a problem after the restart.
A prompt appears on the screen: "The C drive has an error and cannot be installed. It cannot be repaired." ” This error has never been encountered before, so I went to the network to find a statement, and finally found a solution to the problem, the emergence of such problems are generally used when installing the system with a new hard disk, the only way It is to re-partition the hard disk and reload it.
But the author has important data in the hard disk in the back partition, can not be re-partitioned. This can be difficult. If you want to re-partition and export the data beforehand, it is easy. You can hang the hard disk on another computer and copy the data directly to another hard disk, but there is only one Computer.
Jing Jingxin to think about it, is it necessary to change the hard disk master boot record when Windows XP is installed, have to re-partition to solve the problem? Can re-partition only change the partition information to solve the problem, such as the partition size has changed. Then open the computer and continue to try this method, enter the DOS run PQ partition software, and then adjust the size of the C drive.
Reduce the space of the C drive, so that the partition information of the C drive will change, and only the capacity of the C drive will be adjusted, and the data in the subsequent partition will not be lost. After the adjustment, save and exit, or reinstall Windows XP again in the previous order. When the file is restarted after restarting, the problem does not appear and the installation ends smoothly.
This error can usually occur when installing Windows 2000/XP/2003, although the chances of occurrence are small. But if it happens, changing the size of the system installation disk is the best way, it will not affect the data in other partitions.
