Windows 7: Re-installing Windows 7 Error Help Please

Re-installing Windows 7 Error Help Please

I am not tech savy, so pardon me if I say the wrong thing or don't understand the answers!

I have a HP Pavilion dv7-6c95dx entertainment PC (laptop) that was working for about a year. It started bluescreening, so Microsoft Tech support tried everything, and finally erased the computer entirely and mailed us Window 7 Home Premium and told us to reinstall it. We tried to install the 64 bit version, (and the 32-bit version after the 64 failed) and after 84% installation (64 bit) I get this error code: "Windows cannot install files. The files may be corrupt or missing. Make sure all files required for installation are available and restart the installation. Error Code 0x80070570"

I have called HP and since this laptop is just over the 'warranty' they will not help me without charging me. I paid Microsoft $150 for a service contract, and after we got this error code they are refunding me the full amount and they have washed their hands of it. Does anyone have any step by step directions on how to fix this or what might be the problem? Any assistance is appreciated.

Hi there,

Try again with one stick of RAM and if it doesn't work, move the same RAM module to the other slot. If it still doesn't work, try the other RAM stick in each of the two slots.

One of the RAM sticks or RAM slots could be defective.

If that fails:

In your BIOS, check if the voltage and timing are set according to your type of RAM.

Test the RAM - Test with Memtest86+ for 5-6 passes or overnight.

In addition test the HD with maker's Hard Drive Diagnostic Procedure extended CD scan.

Unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. (If an EFI BIOS you'll need to decide if you want UEFI BIOS vs. Legacy BIOS. If UEFI follow these special steps for Install, otherwise enable Legacy BIOS or Compatibility Support Module to proceed with normal install.) Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here.

At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

DISKPART
LIST DISK
SELECT DISK 0 (after confirming Windows 7 target HD #)
CLEAN
CREATE PARTITION PRIMARY
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failures.
