I could not find my original post and answer which was on 11/21/10. It was answered by Andre Da Costa. The advice given did not work...disable security, disconnect devices, do a "chkdsk", and then do "msconfig" to disable startup programs and all services except Microsoft. I also ran the upgrade advisor which said I was good to go.
I put this problem aside for awhile planning to contact Dell to get help to get Windows 7 installed. In the meantime another problem occured due to malware and registry errors. I had to have a tech come to my house to get this fixed. The result was that I had to backup all my data and then reinstall my original Vista. He said that with a clean install of Vista there should be no problem upgrading to Windows 7 and then reinstalling all my other software. He could not stay to help with the upgrade since this was likely to take several hours to complete due to all the Windows updates that had to be downloaded and installed. It took over 7 hours to get all the updates.
So now I get the same error. Do I do the original advice again? That took a couple of hours and only found a couple of errors, which were fixed.
Thanks Kris Besch
Thank you for using the Dell Community Forum.
What computer system do you have that is giving you this error? Have your tried just doing a fresh install of Windows 7 without doing an upgrade? Did you download Windows 7 from MSDN?
I have a two year old Dell Inspiron 530. I have an upgrade disk that I purchased from Dell after chatting with a rep who said there should be no problems. Can I do a fresh install with an upgrade disk? My son, who works as a programmer said that a fresh install would be better also. He said I should try to just boot up from this disk by putting the disk in but when it comes to the screen to coose what to do, I should shut down the computer. Then turn it back on again and it should then install. Do you think I should try this or just a regular installation disk?
Well it didn't work your way or my son's way. I still got the same error code at 33% of the first step - copying Windows files. And just to be clear, you said to "boot to the Win7 disk". To do this I put the disk in the drive. When auto-run opened, the choice was to run Setup or look at the files on the disk. I chose to run Setup. I hope this is what you meant.
Here is the error word for word:
Windows cannot copy files required for installation. Make sure all files required for installation are available, and restart the installation. Error code 0x800700001.
Where are the required files? On my system? On the disk? Is this disk possibly corrupt? Also, when it got to the screen to pick which partition to install to, I chose the C drive but I noticed two links on this screen - refresh and load drivers. Am I supposed to do something here? There was also message that popped up regarding making a new partition and restarting Windows. I didn't think I was supposed to make a new partition.
I also tried to do this with my security software turned off. No luck there. All I have installed since reinstalling Vista are Adobe reader and Windows Security Essentials.
So what do you suggest now?
You are receiving this error because Setup is unable to validate the Windows image file; it believes it to be corrupt.
There are a number of things that can cause this but most often it's due to "bad media".
Assuming that this ISO you downloaded has a valid CRC check, you should try to :
When you choose to download most software from the Microsoft Store, you have the option of using Download Manager or downloading from your browser. However, when you purchase Microsoft Windows 7 from Microsoft Store, you have an additional choice to make: whether to download a collection of compressed files or to download an ISO file. An ISO file combines all the Windows 7 installation files into a single uncompressed file.
If you choose to download an ISO file (so that you can create a bootable file from a DVD or USB flash drive), copy your Windows 7 ISO file onto your media and, run the Windows 7 USB/DVD Download Tool. After you do this, you can install Windows 7 onto your computer directly from the USB flash drive or DVD.
Note: When you download the ISO file, you must copy the file onto a USB flash drive or a DVD to install Windows 7. When you're ready to install Windows 7, insert the USB flash drive into your USB port or insert your DVD into your DVD drive, and then run Setup.exe from the root folder on the drive.
The advantage to following this process and creating bootable media is that it allows you to install Windows 7 without having to first run an existing operating system on your machine. If you change the boot order of drives in your computer's BIOS, you can run the Windows 7 installation directly from your USB flash drive or from a DVD when you first turn your computer on. (Please see the documentation for your computer for information about how to change the BIOS boot order of drives.)
If you need to download the software again, you can go to your Download Purchase History in your Microsoft Store account and access the download there.

When creating a bootable USB device, I am getting an error about bootsect
To make the USB device bootable, you need to run a tool named bootsect.exe. In some cases, this tool needs to be downloaded from your Microsoft Store account. This may happen if you're trying to create a 64-bit bootable USB device from a 32-bit version of Windows. To download bootsect:
My USB device is not in the list of available devices
If you don't see your USB flash drive in the list of available devices, please make sure the drive is inserted in the USB port, and then click the Refresh button beside the list of available drives.
I inserted a blank DVD in my DVD-ROM drive, but the Windows 7 USB/DVD Download Tool doesn't recognize it
If there are multiple drives on the system, the tool will select the first one that is capable of burning DVDs. If you have multiple DVD-R drives, try inserting the blank DVD into another DVD-R drive. If that doesn't help, please make sure that your disc isn't damaged and that your DVD-R drive is operational. Contact Product Support if issues continue to arise.
I inserted a blank DVD in my DVD-ROM drive, but the tool won't let me burn it
Make sure the disc isn't a dual-layer DVD disc. Currently, dual-layer discs are not supported within the tool.
I don't think this answer applies. I did NOT download the upgrade. I bought an upgrade disk through Dell. Do you think this disk is corrupt? Should I request a replacement disk?
