Unable to boot up

July 23, 2012 at 15:27:47
Specs: Windows 7
I have a dell laptop running windows 7, 64 bit. I acquired a virus and before I could get it cleaned off, my machine shut down. When I try to boot, even in safe mode, all I get is a blank screen with a blinking curser at the upper right corner. I have tried a recovery disk (booting off the cd drive) and it goes though the motions as if it s going to work but eventually goes back to the same problem, still no bootup. Any help I can get would be greatly appreciated.

Hi ttown5255,

My name is Munawar from DELL social media outreach team

With reference to your post regarding your computer not booting to windows, I would suggest you to run startup repair using the Operating systems disc (Windows 7).

In order to do that, please perform the following steps:

1. Insert the OS disc while the computer is on and turn off the computer.

2. Restart the computer and keep tapping the F12 key as soon as you power on the computer.

3. On the boot device menu, select on-board CD/DVD drive and hit enter.

4. Then, you will see a message which will appear for 1 or 2 seconds which will say “Press any key to boot from CD or DVD”. As soon as you see this message, press any key on the keyboard to proceed to the next step.

5. On the next screen, select U.S English as the keyboard layout.

6. Next, on the install now page, select “Repair your computer” which will appear on the bottom left hand corner of the page.

7. It will then take you to the system recovery options page. On the system recovery options page, please select “Startup Repair” and hit “Next”.

8. The OS disc will repair all the damaged Operating system files and boot the computer to windows.

In case the Startup Repair did not fix the problem, Please try the same steps again
Follow from Step 1 to Step 6, then on the system recovery options page select the option "System Restore" and select the date to which you want to have the computer restored.

Please let us know if this helps

I tried both suggestions with the exact same results; when the machine reboots I get a blank screen with a blinking cursor. Do you think I need to reinstall windows, and if I do, will I lose all of my data.

Maybe. Maybe not. Obviously the OS (Windows) is not working anymore so we need to use another OS (in this case Ubuntu) to fix it ... maybe. If we can't then yes you'll have to reinstall (and loose your data). Follow this link to learn how, try it, and let us know: http://www.addictivetips.com/window...

" if I do, will I lose all of my data"

Yes. To do it properly, you need to delete ALL your partitions.

Make sure when you reinstall, you delete ALL partitions & format to NTFS.

I tried this, and everything appeared to work. I restart the computer and got the same issue; blank screen and blinking cursor. And still not able to boot in safe mode either.

Three Live CD Antivirus Scanners You Can Try When Windows Won’t Start
http://www.makeuseof.com/tag/live-c...
Can’t boot your computer, and think the problem is malware? Boot a live CD made specifically for scanning your computer without starting Windows. A live CD is a tool that boots completely from a CD or a flash drive, meaning you can use these tools whether Windows is working or not. A variety of live CDs exist that make it possible to scan your computer for viruses.
Recently I wrote the manual 50 Cool Uses For Live CDs. In this manual I pointed out a variety of different disks made specifically for scanning for viruses. Five such tools are highlighted in the manual; find out about three of them below. Be sure to download the manual to read about the rest!
