Windows cannot copy files required for installation. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070570

I figured it out.  Looked at the error logs and saw I didn't delete the temporary installation folders.  Deleted them and got past the error.  FYI for anyone else.

is this really the solution?

For the person who asked the question, yes it was. It's not the only answer.

Does this mean the CD is corrupted? I just wasted $200 f***ing $$$ for nothing.

If the DVD is bad you can return it, or replace it.

Error 0x80070570.

This is common for a Dell computer, but can happen on non Dell computers. It appears that the built-in SATA drivers aren't recognized during the Windows 7 extraction portion of setup (when your BIOS is set with RAID Autodetect/AHCI).  This can work for Dell PC and a non Dell computer:

   Note: you should install the latest BIOS update from Dell's support.dell.com website first, or your manufacturers website for a non-Dell computer.

1. Boot into the BIOS (for Dell press F2 while the Dell splash screen is showing, other computers may use a different button).
2. Go to Drives > SATA Operation. (will be different for a non-Dell)
3. Change from "RAID Autodetect / AHCI" to "RAID Autodetect / ATA" (or something similar)
4. Press escape, choose Save / Exit.

Play it safe, shut down your PC and disconnect all USB devices (except the keyboard/mouse) before trying to reinstall.



This can also sometimes be caused by bad RAM, you can use the memory test feature on the Windows 7 DVD.


This error might also occur if the hardware is not compatible, you may check if your computer meets the hardware requirements for Windows 7 from the two links below:

If the above doesn't work run chkdsk in Windows Recovery Environment [RE] which might help to fix the issue. You can access Windows RE using the Windows 7 installation disc or a system repair disc you created earlier. To use this method, you need to restart (boot) your computer using the disc.

1. Insert the disc.
2. Restart your computer using the computer's power button.
3. If prompted, press any key to start Windows from the installation disc.
• If your computer isn't configured to start from a CD or DVD, check the information that came with your computer. You may need to change your computer's BIOS settings. For more information, see BIOS: frequently asked questions.
4. Choose your language settings, and then click Next.
5. If you are using the Windows installation disc, click Repair your computer.
6. Select the Windows installation you want to repair, and then click Next.
7. On the System Recovery Options menu, click command prompt to open it.
8. In the command prompt window, type the following command and press enter Chkdsk /F /R
9. Press Y when you are prompted to check the disk the next time that the system restarts.

Note: During the restart process, Windows checks the disk for errors, and then Windows starts. Now run the check disk in command prompt, follow the steps below:
