Windows 7: Got A Virus, Did A Windows Reinstall, Now Have An Error Message

Got A Virus, Did A Windows Reinstall, Now Have An Error Message

Hello Everyone, I'm new to the board and I just want to start off by saying thank you to any help you can give in advance.

Here are my computer stats:
Acer Aspire One 7741Z
17.3" Display
3GB of DDR3 Memory
250GB Hard Drive
Windows 7 64 bit

My issues started with me getting a trojan.agent. I had several trojans and viruses and I could only be in safe mode for any extended period of time. If I started in normal mode, I would get the BSOD in about 2 minutes.

I went through a number of steps to try and correct the problem under the supervision of another forum. We did combofix and a million other things it seemed the problem remained.

Finally, I just decided to reinstall windows. Everything went fine through the reinstall and I was really happy. But then when it restarted, it started normally and sounded good. But when it went to setup the computer I got this error message: to install windows, click ok to restart the computer and then restart the installation".

I restarted the computer and of course got the same message.

Also based on the research I've done, it seems like there are some changes that can be made in BIOS to help fix the problem. However, any of the changes they suggest, I can't find those settings (voltage, plug and play, etc.). It seems my options in BIOS are very limited.

Any help you give would be great. It could save me from buying a new laptop. Thanks.

Where did you get the Windows 7 installer? Try downloading the latest official ISO with SP1 from here: Win7 Home Premium x64 SP1 English Official ISO download

Burn to DVD or write to flash stick using Windows 7 USB-DVD Download Tool.

Unplug all peripherals, follow these steps to Clean Reinstall Windows 7 Factory OEM

You can also try running Acer factory recovery from its partition? Acer Support: Restoring a system to factory load . If this is what you did, then run Startup Repair from System Recovery Options

Next enter BIOS setup and reset to defaults. Then look for SATA controller setting and set to AHCI.

Next try wiping the HD with Diskpart Clean command: SSD - HDD Optimize for Windows Reinstallation

If install continues to fail during setup phase, try entering Device Manager during install to uninstall any device drivers which are showing in error, then when install completes update from desktop: Device Manager - Access During Windows 7 Installation

If error continues, report back or google the verbatim error message to find how others have solved it.

I suggest the following. Load your installation disc and find the Command Prompt (under the repair options). Then run these commands:

Diskpart
List disk


Select disk n(where n is the number that was given for your disk where you want to install)
Clean
Create partition primary
Assign Letter=T (you can choose any other letter, but it must be available)


Active
Exit

I always assign my own letter so that I can id the partition I just created.

Now install into this partition.

Wow such quick replies. Thanks!

I used the Acer eRecovery disc to reinstall. So should I still try that Windows 7 Dvd link and try and do it that way? Is that better than the Acer eRecovery disc?

It's a cleaner reinstall since it doesn't include the Acer bloatware and useless factory utilities which have better versions built into Windows 7.

The steps are all in Clean Reinstall Windows 7 Factory OEM including to put the Wireless LAN driver on a stick or CD so you can get online quickly after install to get the latest drivers from optional Windows Updates. Any other drivers then missing in Device Manager can be found on the Acer Support Downloads page here: http://support.acer.com/us/en/produc...1&modelId=2193

If you have access to a Windows 7 System Repair Disk you can boot it now to run Startup Repair a few times as it might yet start.

If you'd rather try again using the Recovery disks then I'd wipe the HD first using the steps given earlier. It's too bad you didn't run the Recovery Partition as it is a more stable method than the Disks. There's a possibility it might still run if you try it from the tutorial linked.

Let us know how it goes.

Okay I have another question and forgive me if this is said somewhere but in step number seven it says to enter the Product Key. I don't have a product key to enter. The computer came with windows seven on it so I never needed a product key. Where should I look for that? I've looked on the computer but I can't find it. Suggestions?
