Windows 7: Error Code 0x8007050


27 Jan 2011   #1

Windows 7 Ultimate 64 Bit
 
 
Error Code 0x8007050

I have been encountering this same error code in one of my machines. I get the Error Code: 0x8007050 during installation of Win 7 Ultimate 64 Bit. It occurs during the expansion of files phase, during instalation, with the message "Windows cannot install the required files. Make sure the required files are available..."

Machine Specs: Intel DP43TF MB, Intel Quad Core 8300 CPU, 4GB OCZ ATI DDR2 RAM, Antec 500 Watt PSU, Hitachi HDS725050 KLA360 HD, and later a Seagate ST3640323AS HD.

In previous installations of Win 7, I've observed that about 29MB are copied to the System Reserved partition. In this scenario, only 11MB are copied. I've performed the following trouble shooting in order:

- Changed out the DVD drive. Tried installation again without success.
- Performed factory system restore on the hard drive. Tried installation again without success.
- Replaced the hard drive with a new one. Tried installation again without success.
- Removed all PCI cards, and tried again with just the PCI-E video card. Tried installation again without success.
- Replaced the PCI-E video card with a PCI card. Tried installation again without success.
- Cloned the "System Reserved" partition from another PC with a functioning install of the same OS. Tried installation again without success.

It should be noted that this specific machine was previously running Win 7 Ultimate 64 Bit. I was simply attempting to upgrade the hard drive. I've also tried to install Win 7 Home and Win 7 Pro, all with the exact same error code, which occurs during the same phase of installation.

I also tried to perform an Upgrade install. The machine accepted a complete install of Win Vista Ultimate 64 bit (twice), but had the same error codes appear during the Upgrade install to Win 7 Ultimate 64 Bit. I reformatted and reinstalled same Vista 64 bit OS. I tried to install Win 7 Pro 64 Bit, and again encountered the same error codes. Incidentally, I have used 3 different Retail Win 7 install media.

The machine passes all MemTest and CPU diagnostics. What is the soluton to this problem...?

Hello wprivera, welcome to Seven Forums!



If the Windows 7 install disk is one you burned yourself it may be a bad burn and needs to be done again, if so this would be the first thing to try.

Use the free ISO burner at the link below to burn another at a speed of now more than 4x and select to let the program to verify the disk before it finishes.

Then second, after you have copied out or made back-ups of the data you need to save; you will need to do a wipe (secure erase) of the entire Hard Disk Drive, then use the outline in Step Two #2 to create a single 100GB partition to install Windows 7 to, later the rest of the HDD unallocated space can be added to the OS partition, if you choose; have a look at this info below and be sure to post back with any further questions you may have and to keep us informed.

After you have made backups of everything you care to save and you want to do a real wipe "clean all" to the Hard Disk Drive (HDD) have a look at this tutorial at the link below, it over-writes everything, all the old Windows code including all the old Windows drivers, giving you the best possible space to install Windows 7 to; it goes hand-in-hand with a clean install.

Solution:

In my original post I stated that I was using Retail Instalation Media, not something that I burned. In any event, since I posted the question, I "stumbled" upon the solution:

Restored BIOS settings to Failsafe Default. After a little deeper investigation, I discovered that the BIOS was configured to automatically detect RAM default settings. It had incorrectly set them to 5 - 5 - 5 - 15 and 1.8 v. OCZ recomends that this particular RAM be set at 4 - 4 - 4 - 15 and 1.9v to 2.1v. I manualy changed these settings in the BIOS. The machine accepted a clean install of Win 7 Ultimate 64 Bit. This is the most convoluted problem I've encountered to date.

Did you try to confirm by setting BIOS back & forth??

Did you verify that BIOS memory setting was the problem by changing back to original settings and seeing if you got the same install error message?

IT IS VERY HARD TO BELIEVE that a memory BIOS setting could reliably cause the exact same software generated error. Why would memory fail at the exact same poing in software installation?

I apologize for just stumbling on this thread. Because wprivera writes so well and appears very organized, I wanted to raise this question, although the thread is now stale.
