Post by: matty.green2000 on November 25, 2015, 01:21:41 PM
Hi,

I recently installed Avast Antivirus Free on a few computers, i later uninstalled it, because it were stopping programs working over the network, after it uninstalled, i restarted the computer, as i was prompted to. When it restarted it booted into Startup Repair, but it states that "Startup Repair cannot repair this computer automatically".

This is the Problem's Details
Problem signature:
Problem Event name : StartupRepairOffline
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown
Problem Signature 04: 21199533
Problem Signature 05: AutoFailover
Problem Signature 06: 13
Problem Signature 07: CorruptFile
POS Version: 6.1.7601.2.1.0.256.1

Please can i get any assistance, i do not want to re-install Windows 7, because then i will have to set up the network again, is there any other way to clear this issue?

The tool needs to run in safe mode.
If that isn't working either...

Scroll down to "If you cannot  Boot the computer" and follow the instructions.

I created the boot cd, but while it is trying to load the Reatogo desktop, it give me a blue screen, i've tried it with 7 of the computers. I then restart the computer without the cd in, and it gives me the same error. What else can i try?

Okay, so i used Rufus and i loaded the FRST.exe onto the flashdrive, i then rebooted the computer, which then booted into the FreeDOS kernel, i then typed in the command "FRST.exe" and pressed enter, it then said that "This program cannot be run in DOS mode".

What should i do now?

You need to create a bootable usb stick with Rufes that boots Windows.

So if i create it so that it boots windows, won't i lose all the data on the computer?

No, you need to create the usb stick so that a windows environment is loaded.

OK you have two files missing... One I can replace with FRST but the other unfortunately will require a repair install  http://www.sevenforums.com/tutorials/3413-repair-install.html

Could i not possibly copy those two files from one of the working computers and then just them onto a broken computer using the copy command on cmd prompt?
Title: Re: Avast Uninstall Problems
Post by: essexboy on December 01, 2015, 10:21:07 PM
No, because this one is created by the system and is specific to it

C:\Windows\system32\codeintegrity\Bootcat.cache IS MISSING <==== ATTENTION

I created a system image off of one of the working computers and then i created a recovery disk, i then loaded the system image onto a hard drive, i then booted the computer into the recovery disk and then used system recovery to load the system image onto the computer. Hope if anyone has this problem they can use this information and use the help from eddy and essexboy, thanks so much for the assistance.
