[REDACTED]

Hi, firstly sorry if this isnt the correct place to put this post.

My computer wouldnt start this morning so i tried to boot into safe mode but it stops at the line

Loaded:\windows\System32\Drivers\aswRvrt.sys

googling this line brung me here, not sure what else to say or what information is required but to start off i'll tell you i'm running Windows 7 Pro 64 bit and we can move on from there. Guess all i can do for now is await any replies. Hope someone can help.

OK   boot to the recovery console
Select Command prompt
At the prompt type the following and press enter :

chkdsk c: /r

Once it has completed try a normal boot

[REDACTED]

still wont boot, it takes me to a Windows Error Recovery screen, when i select Start Windows Normally it goes to a Starting Windows screen with the logo and nothing else happens.

[essexboy]

Try the Repair my computer option now... If that fails then try and run a fresh FRST scan please

[REDACTED]

i dont get the screen that has the option to repair my computer. when it starts up it asks me to choose a language then searches for an installed os but it doesnt find one.

[essexboy]

Did chkdsk find errors as your MFT was corrupt

[REDACTED]

Sorry i dont know mate i never actually looked, i know stupid but i was kinda hoping it would be ok. When i get time ill run it again and record what it says. Im heading off to work soon and wont be home again until probably sunday afternoon maybe monday morning can we resume this then?

[essexboy]

Aye for sure

[REDACTED]

[essexboy]

Unfortunately it looks like you will need to re-install windows

then searches for an installed os but it doesnt find one

suggests that there is a major problem with the MFT

[REDACTED]

Kinda had the feeling that was going to be the outcome after seeing the frst log, let me ask you this, was avast responsible for this?
