WIN 7 wont Boot!

[thead73]

i ran malwarebytes then win 7 wont boot up. i cant F8 and get to safe mode either. i tried the Win 7 DVD and the startup repair didnt work either. i can see C: drive directory in the dos prompt and can see files on hard drive. i think malwarebytes deleted something in windows startup. can anyone help

on some of these programs you need to watch what it does .


what was it doing before you ran the malwarebytes .

Brand and model of your computer?

Which Windows 7 CD are you using?

Can you reboot and enter the recovery partition?

i just ran a malwarebytes full scan and went upstairs to eat sandwich. computer was runnin fine just wanted to scan to check for any bad cookies or what not. when i came back 30min later screen was off and wouldnt resume. so i rebooted it and now it doesnt load win7 just says insert CD/dvd. i just looked in bios and the time is set to march 2000. and it wont let me change it. under IDE channels it see my cd/dvd drive but i dont see my Sata hard drive listed any where, did bios not detect it?
this is a computer i built to game on. it has a gigabyte board. i was running win 7 ultimate.

when i run the win7 dvd i can get in dos prompt and see my C: drive and windows dir.
i would like to see if i can get this to boot as i dont want to reload win 7 and have to start all over with all my games and patches and drivers. thanks

Hi,

Its possible that Malwarebytes deleted a system file that was infected, causing instability in your system - Malwarebytes doesn't touch anything that is not infected. What was your reason for running Malwarebytes in the first place? What is the original source of your Windows 7 installation?

i tried startup repair many times and it said it couldnt fix the boot problem. my bios does not seem to show my sata hard drive. but when my win 7 dvd is in i can access my windows folder and contents and browse them. i also did a chkdisk and it came back with no errors. any help restoring what got lost so i can boot up win 7 whould be great thanks

Hi,

What type of infection did you have when you started running Malwarebytes? What is the source of your Windows 7 CD/DVD?

It's not an IDE, so can't check the jumpers. Can't flash the BIOS, hum?

 

[thead73]

i dont know of any infection. i run malwarebytes every now and then to check if there is anything bad to remove. last time i ran it it found nothing. this time i started full scan and when i returned monitor was off and would not resume. i had to reboot computer and now it wont boot. i think my win7 dvd is a oem i purchased online when i built this computer.
any help would be great thanks. windows gives me a boot error file \boot\bcd

i think my win7 dvd is a oem i purchased online when i built this computer.

Hi,

Can you be more specific? Which online location did you purchase this system builders OEM?

i believe it was newegg. should i see the sata hard drive listed somewhere in my bios because i dont see it listed all i see is the cd/dvd drive

 

[thead73]

also my bios date went back to march 2000 right after i ran the malwarebytes scan. i just put it back to 2012. what is going on with this computer.

Just got here, trying to read through all these symptoms. Weird!

Tell us exactly what happens after you power up. Do any screens show up? Does the screen remain black? Take the side cover off. Do you here any sqeaking or grinding noises? HDD can fail both electrically, and mechanically. Cause randon crashes and data loss. This error message, when do you get it. Is there any code numbers. Tell us in a, step by step, as it occurs.

 

[thead73]

when i turn on comp post looks normal, but does not load windows just has text saying boot from cd/dvd. hard drive seems to be still good, hard drive light blinks normally and i can access C:dir in dos prompt and it shows windows directory space avail on drive

 

[thead73]

i believe malwarebytes deleted something and windows dvd startup repair wont fix it. anyway to replace startup code to get it to boot win 7?

 

[quickdraw2011]

I believe the only thing to try is a system recovery. If it will not recovery, then I'd look toward a hardware failure. So, it happened to occured during a system scan. That does'nt mean Malwarebytes cause all this. It just may of been enough to send the HDD into failure. I've seen motherboards do the same.

 

[Sub Zero55]

You could take the HDD and try it in another PC?

Does your motherboard have a green light, if so, is it blinking?

 

[thead73]

yes the hd light is blinking slowly just as it always has. i can access the C:\windows directory no problem. i even copyied the software , system, and Sam files that were backed up from last weeks registry. that worked fine so i think the drive is okay. but it still wont boot. something is still missing

 

[gregrocker]

If you didn't complete the scan by cleaning up any items which Malwarebytes found then it didn't remove any. More likely it found an infection which became agitated and spread, or something unrelated happened.

thanks for the replys. i have no idea what happened. i finally got it booted last night. and went to malwarebytes log and it didnt have logs or info from the scan, so i think it didnt remove anything. it might of been a bad hard drive or bios error. i dont know. all i know is weird stuff was happening. time was off in bios and it wouldnt show hdd in bios at all. but i could access drive from win7 dvd command prompt. after resetting bios a bunch of times and it finally saw hdd. and after coping some registry backup config files. and some other tinkering it finally booted. i replaced cmos battery today even though i dont think it was dead. its runnin fine now we'll see how long it will last. thanks again
