No luck I'm afraid...it's not looking too good for the laptop.

Avira did not even find any "Suspect files"

Back to the Recovery Console:

Type in the following pressing enter after each line:

d:
cd i386
copy iastor.sys c:\windows\system32\drivers
copy atapi.sys c:\windows\system32\drivers
copy lsass.exe C:\windows\system32
exit



Try to boot, did it work?

Well there's been some progress.

I replaced all three files of which the iastor.sys file did not need to be overwritten, so i'm guessing it was not present on my laptop.

Now when I try to boot the laptop a blue screen appears with the following message: -

" A problem has been detected and windows has been shut down to prevent damage to your computer.
If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:

Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated.
Run CHKDSK /F to check for hard drive corruption, and then restart your computer.

Technical Information:

***STOP: 0x0000007B (0xf7c0d528, 0xc0000034, 0x00000000, 0x00000000)"

In the Recovery Console, run this command:

chkdsk /f


then let me know if it helps.

Tried to run chkdsk /f but it returned

"Invalid parametres type /? for Help"

Recovery Console did however give me the options of: -

CHKDSK /p
CHKDSK /r

with recommendations for running /p then /r then /p again. I did exactly that and it returned with CHKDSK finding one or more errors after /p then CHKDSK repairing one or more errors after /r and finally CHKDSK finished the scan with no errors after the second /p scan.

After all that on booting the laptop up the same error screen as mentioned in my previous post appeared.

Hope that makes sense.

In the following article, it asks you to reformat and reinstall Windows.
[You must be registered and logged in to see this link.]

I am sorry you have to reinstall Windows, but you have over two bootable disk errors, which signify severe corruption on the partition itself, not Microsoft Windows. In the event this happens, it is best to just delete or format the partition that Windows sits on, then create a new simple volume to let a fresh install of Windows to lie on.

Ok no worries, I am extremely grateful for all of your time and help.

Does this mean that I will lose all of the data on my laptop? I have lots of files on my laptop that are extremely important.

Any further help would again be extremely appreciated.

On OTLPE, you might be able to transfer files to a flash drive, then you might save the data.

I still have some testing to do on OTLPPE to be sure of that.
