SOS can t install the system

An example of someone else.

Example: One day, when the computer restarts and enters WinXP, the system prompts: "SystemRoot System32 file is illegal or the file is corrupted, the system cannot boot".

I thought that I could use the Failback console to repair corrupted files.

Just restart your computer and select the Crash Recovery Console. Everything goes into the windows directory step by step. But I don't know which package the file is located in on the installation CD, so I type the following command:

expand G: i386: for the drive letter), lists all the files in the driver cab archive on the Windows installation CD, found in the archive.

Immediately enter Expand G: i386 C: at the DOS prompt

windows\system32\。Restart the computer immediately, but I didn't expect the same prompt as the first time, it seems to have failed.

But it clearly indicates that the copy is successful! If you think about it, could it be that other files were renamed by the setup program when the system was installed? (Just like win98 was renamed from win98).

So I used the expand d g: i386 command again to find hal*dll file, the result is to find six files, in order to copy to c:

Windows system32 and restart the PC after renaming, no. Copy again, restart after changing the name, and finally recreate the cute desktop!

After successful startup, immediately enter the system C: Windows system32 directory to view the properties, mouse click on the "version" tab on the "source file name", the source file name is indeed is.

1. First of all, close all other running programs, because it may be that the use of other programs occupies the target volume, resulting in the problem that it cannot be locked.

2. Before installation, some users open the DG partition tool, and at the same time, the tool will occupy the target, and the task manager can be called up to close all non-system programs.

3. Restart the computer after closing the program, do not open other irrelevant programs after entering, and install it directly, and you can install it smoothly at this time. Or use the U disk boot disk to enter the PE system, format the installed target disk, and reinstall the system, so that the target cannot be locked prompt will no longer appear.

2. Start the partition assistant, click the SSD hard disk, and click the partition alignment (4K alignment) in the [Partition Operation] item on the left side of the partition assistant window;

What is 4K Alignment, i.e. a hard drive that is formatted in accordance with the 4K sector definition, and data is written according to the rules of the 4K sector.

The impact of not doing 4K alignment on SSD hard disks: If 4K alignment is not carried out, in the previous specification, the write point of the data is exactly between the two 4K sectors, even if the minimum amount of data is written, the two 4K sectors will be used and rolled together, so the impact on the write speed and read speed will be great, so the 4K must be aligned.

For SSDs, if 4K is not aligned, it will greatly reduce the speed of data writing and reading, and will cause unnecessary writes to SSDs.

After kalignment, click the [Wizard] item on the left side of the window to migrate system to solid state disk, and in the open migration system to solid state disk window, click: Next;

4. Follow the prompts to migrate the system from the original mechanical hard disk to the solid state disk.
