    I have vista home 32 bit and tried to fix what I thought was TDDS rootkit. I used Malwarebytes to scan and fix 4 errors and then used Kaspersky virus removal. After that I went to blue screen 7b. Can't boot in any mode. I have read many posts online about similar situations but can't seem to follow a procedure to get working again. Can you help?

    Thanks.

    Attached is fixlist.txt

    Now re-enter System Recovery Options.

    Did you do any troubleshooting on your own before you posted here?

    I am mostly interested if you went into the system BIOS at all.

    I did change the harddrive setting in BIOS from SATA to IDE, rebooted, no change, changed it back to SATA, no change. That was the only change in Bios I made.

    Do you remember what the HDD controller setting was set at originally before you had these problems?

    Try toggling this setting once again (change it to IDE, and if applicable AHCI), then revert it back to SATA if the PC still does not boot and perform a new FRST scan.

    You probably know this but now that I'm back BIOS it was RAID not SATA. So switched to IDE, no change. ACHI no change. ATA/IDE mode Native the whole time and SMART enable. Back to RAID no change. Each time I try and boot I get the launch startup repair option, when I try and choose it it does nothing just resets the 30 sec timer. I choose boot windows normally then get the blue screen right after the window logo shows. Thanks for your help tonight I'm off to bed. Hopefully you'll find an answer.

    Sorry, too many cold meds last night. I guess I sent the wrong file. Is this right?

    Go into a bit more detail on this.

    Do you have your Windows Vista DVD? Can you try entering Startup Repair from there?

    I have tried fixing from the windows dvd many times, no luck. Actually I found an old image and got it to restore last night. not the best solution but at least it is working again. Will have to reinstall some things and find some data files but didn't have any confidence we could get the thing fixed. thanks for your help.
