PC won't boot aswrvrt.sys
« on: February 21, 2019, 11:31:11 PM »
I'm guided by this thread - https://forum.avast.com/index.php?topic=53253.0

Obviously I cannot run MBAM as the PC isn't booting?

I just booted from USB in a recovery environment where I ran Farbar Recovery Scan Tool, I'll attach FRST.txt but I don't seem to have Additions.txt?

I also tried running 'aswMBR.exe' whilst in the recovery environment but that gives me "The subsystem needed to support the image type is not present"

So that's about the height of it. A little background, I have a SSD (boot drive) and a partitioned HDD (SSD backup / Work files)

Initially I tried the recovery environment and it say it fixed it, got me to reboot and and was actually running from my backup image of my SSD on my HDD. Therefore I powered down and disconnected the HDD SATA cable so it doesn't complicate matters further.

I'll await your guidance, thank-you in advance.

EDIT : Just to be clear, i've booted Windows 7 from USB and selected 'Repair my computer', it tries to fix things but ultimately cannot, then i select 'Advanced options' and finally 'Command Prompt', from there i am able to run 'FRST64'.

No, my apologies, I didn't see it. I just booted again from my Windows 7 USB and it attempted to repair and failed, finally allow me to go in to the Command prompt and re run FRST64. I see no option to tick 'addition.txt'.

All I see is the following;

Whitelist section, Registry (ticked), Services (ticked), Drivers (ticked), Known DLL's (ticked)
Optional Scan section, List BCD (unticked), Drivers MD5 (unticked), 90 day files (unticked)

I pressume that you couldn't boot into Safe Mode. Am I correct?

Unfortunately no safe mode, same error

Obviously no start button, however I navigated to D:\Windows and then typed notepad to get Notepad running, in the recovery command prompt C:\ is System reserved. I did however type everything exactly as instructed..

Results attached

Can you now boot Windows?

Sorry, I never even tried, I was awaiting instructions.. OK, so just tried to boot Windows and even though I was holding down F8 it didn't prompt me with a menu and went straight into loading 'normal mode' Windows 7, the animated Windows icon appeared for a fraction of a second and then it rebooted. I let it do this twice to make sure it wasn't loading 'normal mode' Windows 7. The third attempt I choose 'Safe mode' and it started to load (with all the white writing coming up on screen) and then a few seconds later it rebooted itself.

Sorry, it won't load Windows at this point...
