Hello guys,

i really hope you can give me some new input here :(

The Situation:
Asus Ultrabook Ux31e with only a SSD and USB2.0/3.0 (no optical) was totally messed up. Several viruses -> got rid of them.
But some atheros driver related BSoD still remained, even after a clean driver install. So i tried the repair from inbuilt recovery partition. Not working at all (various errors, sometimes just random shutdowns).
Went on to repair via usb repair stick...and there it got complicated: Boot Manager cant load because of critical system file missing or corrupt. Depending on EFI disabled or not it was pcw.sys or tcpip.sys.
...and windows wouldnt load at all afterwards, just stopped there (in safe mode it loads drivers to those points).
Had a Kali Linux Live usb laying around and used it to check for bad sectors. 3 read only runs - no BS. Thought to myself "well, screw it" and used format on the ssd ( including the recovery) to try a clean win7(64 as it came with that one) install from usb on an empty disk. EFI disabled (when enabled, even with stick setup for EFI, it just gets me to bios).
Guess what...recognizes the stick just fine, loads the files from usb until - bam - windows failed to start. tcpip.sys missing or corrupt (0xc0000098).
The bios version is 211 and the options there are limited to Legacy y/n, EFI y/n and Boot order.

Anyone came across something like this? I read like several dozen pages of forums but everything I tried brought me nowhere near a solution...i´m lost and quite frustrated after like 2 days of trial and error =(

Thanks in advance!


UPDATE: FYI of course I used different official Win7 Iso, so those were not actually corrupt.
In my darkest moment I switched to a 32bit distribution of Home Premium and voilá...it works.
Doesnt really count as a solution as it came with 64bit pre-installed, huh?

 
Solution
I worked out your problem.
You should at least have in the bios an option of secure boot.

If this option is enabled.
Then it was the reason for the failure of windows 7 64 bit.

This would be the case if you in fact had windows 8 64 bit prior to it installed.
And then as you say formatted the SSD drive that contained The working windows boot partition, and also the backup image of the windows os install.

When secure boot is enabled in the bios it stops any changes being made to the prior boot record of windows, It being modified, or over written.

This is why it halted when trying to install windows from a dvd or usb stick.

At what point does the windows install halt.
By that I mean.

Do you get to the point of windows setup where it asks you to select a drive to install windows to IE the ssd drive.

You problem is most likely if you get to the screen where it asks you to install windows, and you select the ssd drive.

Is that you have not pre loaded the sata driver for the laptop that is required.
If you look down to the left, in blue is the option to install a third party driver before the windows install to your ssd drive.

Or when it gets so far through setup or installation it will not be able to copy files to the SSD drive.

Hey Shaun, thanks for the reply.

The problem is, I never actually get this far.

Starting the laptop ->

But it results in one like this (with my error being windows32/drivers/tcpip.sys):
0xc0000098-Windows-8-Release-Preview.jpg


When I press enter to continue I get to the Selection Screen where EMS Setup is the only option:

With pressing F8 for advanced leads to one like this:

Now, whatever option I choose, be it safe mode, debugging...without driver signing...it again leads me to the error from the first picture.
As I said, using Linux, there was no problem adressing the SSD and the error now is actually similiar to the one that occured while I tried repair with the usb drive for the first time - with all the drivers still in place.
