Windows 7: Boot critical file is corrupt

Regulus Leonis,

Go to the ASUS website. Download the manual for your computer. That manual will tell you how to change the boot order.

I strongly recommend putting WDO onto a USB stick. Heck, that DVD you burn will only be good once since the AV database is updated several times a day!

Even department stores, large food stores sell USB sticks. Get a 4 GB so that you have plenty of room (hard to find anything smaller nowadays).

Let's fluff out those system specs a little. Here is how:

Update your SevenForums System Specs
User CP (located on the top menu bar) |
Your Profile | Edit System Spec
(left-hand column)

To gather info, use Speccy (my favorite) or SIW or System Info

In the System Manufacturer Block, enter:
Manufacturer and Model and
ADD the word laptop, desktop, netbook or tablet.
For example:
Toshiba Satellite L305D notebook.

Provide full windows version info, for example:
MS Windows 7 Ultimate SP1 64-bit

Use the “Other Info” block for Optical Reader,
Mouse, touchpad, wifi adapter, speakers, monitor, etc

Scroll down and click on SAVE CHANGES.

You will find that in Speccy, you can select info from the display
using your mouse/touchpad and then paste that info into your specs.

SIW is a marvelous program, but the free version does not offer
this capability.

Reboot and tap the Asus F8 key repeatedly and vigorously to get a BIOS Boot Menu and boot the CD.

Defender may also not clean up Alureon rootkit. Below is the recommended tool. We may also need to call on specialists from our Security forum.

Quote:
Next Download TDSSKiller from Kaspersky to your directly onto your Desktop
  • Now double click the TDSSkiller.exe file to run it ( if using Vista or Windows 7 do not double click on it but rather, right click and select Run As Administrartor. )
  • Allow the application to run if prompted by Windows or any security programs you have installed
  • It will start the scan and run rather quickly and will notify you of whether anything is found or not.
  • Follow the instructions to delete/quarantine if asks you what to do when if finds something.
  • Whether an infection is found or not, a log file should be created on your C: drive ( or whatever drive you boot from) in the root folder named something like TDSSKiller.2.1.1_27.12.2009_14.17.04_log.txt which is based on the program version # and date and time run. Please attach this log to your next reply.

Once inside the BIOS, then go to the BOOT options, from that point on, select a device and you'll probably get still another display.

ASUS does wierd things when it comes to selecting the boot device and the boot order.

Toshiba is much better, but you've got an ASUS. (I also have an asus netbook and changing the boot order is a pain).

Shouldn't the F8 BIOS Boot Menu key work, as long as it doesn't get to Starting Windows when it turns into Advanced Boot Options pumpkin?

No.

He wants to boot into the bios.
See the previously attached snip which is directly from the manual for his notebook.

Yes I saw that is how to access BIOS setup which is normally a separate key.

Is the F8 key which has always been the BIOS Boot Menu key for Asus' no longer that on netbooks?

It hadn't crashed all day until 15 minutes ago and it's crashed a few times since then. F2 takes me to the Boot Setup menu. When I get there, I see:
"CD/DVD ROM DRIVE BBS PRIORITIES"
When I hit enter on that, it takes me to one priority and nothing happens. F10 = Save, so should I hit F10 after selecting "CD/DVD ROM DRIVE BBS PRIORITIES" ? Then Esc to exit?

Edit to add:
I just came back to type that message as fast as I could without reading other recent posts because I thought I only had 2 minutes before another crash. But it has yet to crash so far this time.

Karlsnooks, I saw that page in the manual, as well, and it seems to suggest pressing Esc will give me options of where to boot up to. But it seemed like Esc is just exit. I don't know what a splash screen is so I don't know when to hit Tab.

Download the manual. The manual , at about A-15, shows how to use the boot options.

Greg,
What I know is that for his notebook, one uses the F2 key.

I also know that WDO will remove his malware (the same one has been removed from others).
