Windows cannot install required files. The file may be corrupt or missing.

Make sure all files required for installation are available, and restart the installation. Error code: 0x80070570 The particulars of my setup are as follows: • Late 2008/Early 2009 Unibody Macbook Pro • 2.66Ghz C2D • 8GB RAM (OWC) • 240 GB SSD replacing the original HDD (OWC, running 10.7.3) • 1 TB HDD replacing the optical drive (WD, partitioned 150GB for Windows install) • External USB enclosure w/ Apple Superdrive (OWC) • Install source is a System Builder DVD of Windows 7 Pro SP1 x64. Hopefully I posted this in the right forum. Thanks so much for taking the time to help!

Resizing Windows 10 Bootcamp partition manually. Expanding the Windows partition. Backup all your files (optional but strongly reccomended). Mar 1, 2018 - Use the Boot Camp Assistant to download the Window Support. On my Mac, these files were downloaded to the ~/WindowsSupport directory.

Hello, I don't know if this will help at all but I recently tried to install Win7 64 OEM on my Mac Pro and ran into similar problems because of multiple hard drives. After I pulled all the internal drives and shut down anything external, it actually would go through the entire install process properly. Unfortunately all I get now is a single underscore white cursor at the top left of the screen when I try to boot but at least Win7 installed. Perhaps I'll have to pull the SAS card for the external LTO-4 drive next. Maybe disconnect one of your drives that you aren't installing on and give it a whirl.

I've run into this issue installing on an HP 620 Laptop [Only 1x] when upgrading using CLEAN INSTALL on SSD. You want to make sure you aren't use IDE [AHCI should be set for any type of SSD].

Expanding Windows files is based off the media type you using to install the OS to machine. I used a DVD i downloaded of the.iso and tried both USB external and CD-ROM drive. Both stalled @ 88% forever. I then loaded a new.iso from msft.digitalriver download onto a 4GB USB Thumb Drive, and BAM!! The 'Expanding Windows Files' continued past the 88 percent mark and finished the install completely.

SOLUTION: Try another media type as this was my issue. DVD = FAIL USB FLASH DRIVE = SUCCESS! Hope this helps anyone out there who runs into this issue, Thanks, Kent C. I just experienced the same issue. The cause was a malfunctioning power supplier Hi Alonso, im having the same problem. Download free fundamentals of multinational finance moffett pdf.

How did you identify that it was the power supply. I'm trying to install using a DVD drive. My power supply is a a Corsair CX430. Disk is a SSD Corsair FORCE GS 128GB.

Windows worked fine but then one day started playing up and hanging. It was always hanging when Windows tried to do a system backup. Do system backups consume more power from the power supply? Is there a way to fix the power supply from the BIOS? I remember once someone over the phone asked me to fix something related to the power supply in the bios. ASUS PBZ68-V LE. Now that I think about it, ever since then my Windows Backup feature stopped working!!!
