Windows 7: Installation error "Windows could not update registry data"

Installation error "Windows could not update registry data"

Hi, this is my first post but I have found tons of help on this forum before. My problem is that while installing windows 7 the error "windows could not update registry data in the installation" keeps poping up during the "Installing updates" step, right after the "Installing feature" is completed. I downloaded the several iso from this and this webpages. Also tried USB and DVD (at 1X speed). Found great help on the SSD / HDD : Optimize for Windows Reinstallation and Clean Install Windows 7 guides, I follow them every time I try an installation. But doesn't matter what I do the error "windows could not update registry data in the installation" keeps poping up.

Since I have to keep using the laptop for work I installed Ubuntu 12.10 to finish some projects (worked fine for over a month, no problems) but now I have some days off and I want to fix this.

Other things I have tried that didn't worked
*Using only 1 Ram slot
*Make sure that the HDD is first in boot priority
*Install Win XP
*Iso without ei.cfg

I'm running a Dell XPS Studio 15 L502x laptop, so no RAID.

Thank in advance to anyone that can help me.

PD: I apologies for any misspell or error of any kind, English is not my first language. =D

If you haven't wiped the HD yet then run your Dell Diagnostics to check hardware condition: Dell Diagnostics Utility - How to Run the

Unplug all other HD's and peripherals,

Boot into BIOS setup to enable Legacy BIOS if present. Next check BIOS Boot order for an EFI Boot Disk and if present remove it, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into 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 to open a Command Box, type:

SELECT DISK 0 (after confirming Windows 7 target HD #)
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)

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.
