how can i install Windows 7 on one of my hard disk's partition?

Hello everyone,

Due to the fault on my hard disk, i was forced to format one of the partitions and install Windows 7 Professional 32-bit. But, the installation process can not proceed after Copying the operating System files and displaying an error message.

What is the best remedy to install the operating system on the first partition without losing the data on the 2nd partition?

What kind of fault does your HD have? It may not be able to support a reinstall. To check this you'll need to run the HD maker's HD Diagnostic extended CD scan which can also repair surface errors.

Then run Disk Check to check the file System after formatting a partition with the Win7 installer, then reboot into it, press Shift + F10 at first screen to open a Command Line to run chkdsk /f as given in the tutorial in blue link.

You need to back up your files externally before doing any of this, as should be done anyway especially if you have a HD with "faults."

Once these tests clear the HD, wipe the HD to try booted installation following these steps:

Thanks for the quick reply. But, i was able to sort out the problem. If it helps others, here are the steps the went through:
1) At Windows 7 start screen (after language selection) hit SHIFT-F10 to get command prompt.
2) Run the following commands:
list disk
select disk 0 (your disk may be a different number)
list partitions
select partition 2 (in my case)
format fs=ntfs
exit (exits diskpart)
exit (exits command prompt)

3) Reboot computer.

4) Run setup again and it works fine.
