Windows 7: Windows 7 Instalation CD error

after my harddrive crashing and getting a new one i installed a new one and now i am trying to install windows 7 on this fresh hardrive and it gives me this error after about 10 minutes of it installing nothing installs and i get this error " windows cannot install required files. The file does not exist"

May be the installation media is damaged.

You may download the official ISO of your version of Windows 7 SP1 ISO from here , burn it to a DVD or make a bootable pendrive DVD died. How do I reinstall OS with external USB DVD drive and try installing.

Installing from a pendrive will be faster.

what program should i use to burn this dvd and how would i do it will the pen drive also work with a sd card?

Write to flash stick or burn to DVD using Windows 7 USB-DVD Download Tool

I tried the disk and at first it has started to install and then I lt froze and the 2nd time I did it it gave me this error

Did you download the latest Digital River ISO with SP1 and then burn it using Download tool or ImgBurn at 4x speed. If not burn another now.

Next try writing to flash stick with same tool.

Where can I find the latest

Jumanji linked it for you a day ago. We assumed you were using it.

yes u used his link i assumed it wasent the latest but i guess it is and i downloaded this one -Windows 7 Home Premium SP1-U ISO
English x64: X17-58997.iso
i will try another dvd and i used the windows application for the first one
if not i will reply when i get a usb stick and i will see the outcome

Try also wiping the HD first: SSD - HDD Optimize for Windows Reinstallation

Unplug all other HD's and peripherals.

Reset the BIOS to defaults. Set SATA controller to AHCI first to try install.

Remove all but 2gb RAM to try install.
