w7 not booting up after problems w virus

to start off I had virus/malware/spyware on compute that pretended to show computer crash and everything failed. I used tsdkiller and fixed that part. Then I had google search engine virus still on there which kept redirecting my searches. I used the hitman which deleted all the spyware cookies and something else I didn't get a chance to see. Then rebooted the computer and came up w blue screen error. Stop 0x0000007b (0x80786b58 ,0xc000000d,0x00000000,0x00000000). Keeps going to this, did f8 at boot and tried all the different options to no avail. Repair computer doesn't work, none of system restores work. I have Dell 1720 originally had vista but got disk for w7 from friend so just that op is installed. I have w7 cd still but not cd code. Don't want to reinstall vista bc have expensive software on hd w no CDs left for them. I also ran all the test systems nothing came up w problem. If need more info let me know. Thanks.

 

I'm not sure exactly what the antivirus programs did but since no one has answered I will give a couple of suggestions that might rule a couple of things out.

1) From command prompt you want to try a chkdsk /r on your Windows partition to see if it is a fileystem error. When you choose repair your computer, does it search for Windows installations and give you the drive letter in the little box/window? If so you can type chkdsk L: /r (where L is the letter of your Windows partition so substitute the correct letter for L).

If it doesn't give you the letter you can type diskpart at the command prompt and then type list volume at the diskpart> prompt. Your Windows partition will be the largest one probably over 100gb so get that drive letter. Then type exit to close diskpart and use that drive letter in the chkdsk command. Then see if it will boot.

2) In your BIOS (F2) during the Dell screen. You should find SATA Operation under System Configuration and you want to change it to ATA mode. Then ESC key where you will be prompted to Save and Exit. Then see if any change when trying to boot.

 

I'm at my work now so I was able to upload some attachments of what I did/error message I got. Tried solution number one and it was a no go. The system configuration was already at ATA mode. I also did the options of advance system repair (all the different systems test for trouble shooting and the separate memory test) with no help.

To add on before since I was trying to type with my touchpad, I did get it to boot up one time after playing around with it for awhile trying every solution I could think of. I don't think it was a fix because I didn't catch the stupid automatic reboot for windows upgrade that shutdown the computer, then after that it was the same old error message again

 

This guy had a very similar problem and seemed to be helped by recreating boot files on his OS partition. I'm not sure why that worked? It is rather simple to try so I would do a diskpart to see if that is an option for you.

Go to command prompt and type:
diskpart
list volume
exit (when done)

Let's see what partitions you have on your HD. Output should look something like this:

 

Okay i posted that and I saw the that the other guy did some bootrec so i posted that with the same results as him.

 

Hi

The x07B error you are getting is an inaccessible boot device. Assuming that you have done nothing to the physical disks themselves, I would think that your virus may have disrupted the MBR (Master Boot Record).

I don't know what you may have tried already,but when working with trying to rebuild a MBR, this is what I usually do.

First of all, you need to boot to a Windows RE environment. You will need a copy of the Windows 7 DVD. Start the setup and when you get passed the language screen of the setup, select repair your computer. Hopefully here you will see your Windows installation, if not no worries, hit {shift+f10} to go to the command prompt.

Next since you are going to be doing some destructive work with the Windows boot store, it would be a good idea to back it up by using the command

BcdEdit /Export C:\MyBcdBackup.Bcd

After that try and rebuild the MBR with

BootRec /FixMBR
BootRec /FixBoot

If you saw your Windows installation earlier try and reboot to see if it fixed your problem, if you can not boot to Windows then try the commands below to help.

If you did not see your Windows installation listed then you will have to use these commands as well.

BootRec /RebuildBcd
BootRec /ScanOS

That should fix everything, I have fixed my share of systems doing this so good luck..

TeeStar's plan is fine. I, personally, prefer not to rebuild the MBR on OEM systems like Dell unless absolutely necessary because it can interfere with ability to use special keys to get to the recovery partition.

My plan would be to see if partition 3 is active and if not set it active and then see if when booting from install DVD and the recovery environment the Win7 installation will now be seen and the automatic fixes will work to get the partition bootable.

If you want to try that go to command prompt and type:
diskpart
select disk 0
select partition 3
detail partition (see if the Active status is Yes or No)

If active status is No then type
active
exit
exit

Reboot from the DVD go to the Repair option to get into Recovery Environment and see it it now finds your OS partition as it scans and offers to automatically fix problems.

***
If partition 3 is already active then you would have to try something else.

BTW, do you know what that 2gb partition is at the end of you HD? Did you create it?

 

TeeStar I tried the BootRec /FixMBR and BootRec /FixBoot which was completed very quickly and said successful. Rebooted computer and it was a no go. Sach2 partition 3 was active and ran automatic repair again and could not find a way to fix it. I have don't know what that other partition could be. I don't know how my buddy got w7 to install but maybe it was from the previous os which was Vista. Is there a way I could copy the files from the hard drive and then just transfer them back onto that hard drive once i did a complete reinstall?

 

You can copy data files from the HD and copy them back after a reinstall. But there is no way to get your programs working after a reinstall (except by reinstalling the programs which you don't have the discs for).

Did you try setting the Sata Operation in BIOS to ACHI and trying to boot? If it doesn't help set it back to ATA.

You might want to download Puppy Linux as an ISO file and burn it to a blank CD or DVD. Imgburn will burn the disc using the "Write Image File to Disc" option (Guide). That would give you a bootable disc which would let you copy your data files to a USB flash or external HD.

I may be off track here. The 7b error should not be related to boot files but I don't like that the bootrec /scanos did not find any OS partitions. I think using Puppy to rename your C:\boot folder may force the Win7 DVD to take a harder look at the HD to find your Win7 partition and try to automatically fix the problem.

***
The reason I mentioned the extra partition is that I had seen some threads where malware was creating partitions at the end of the drive. Yours looks like an extended partition rather than primary so I don't think it could cause too much trouble, so it is probably not malware related.

 

Tried setting the Sata Operation in BIOS to ACHI and no success. I'll try using Puppy this week when I get a chance.
