Computer stopped booting

[Kochon]

Hello everyone!

My computer has Win7 Pro x64 and XP in dual-boot, and recently Win7 started going slow when watching mkv videos, and one day it completely lagged to hell, so I rebooted, but it won't boot again, it goes to system repair, but it fails, error found is :



Startup Repair fails from the DVD, too. Could anyone help me out?

Looks like a driver is corrupted. Boot to Startup Repair from DVD and select Command Prompt. From there, type "chkdsk /f" (without the quotations).

Let me know the results.

Well, actually my DVD drive is broken, any other suggestion?

Do you have a USB flash drive?

 

[Kochon]

Sure, you suggest I make a repair USB drive? I've already tried but it failed to boot...

1. Download the Repair Disc (.iso), select the 64-bit (x64) edition, DO NOT select the other one.

N.B: This is a torrent download. Your Internet Browser won't support downloading torrent files. You may find a torrent program to download it in Google. I highly recommend BitTorrent. It's easy to use and fast.

2. Download the Windows 7 USB/DVD Download Tool to burn the .iso to the USB.

3. Follow the on-screen instructions in Windows 7 USB/DVD Download Tool.

4. Once you got the Repair Disc in USB, follow these next steps.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

5. Turn on your computer, boot into your BIOS. (This happens before booting into Windows)

6. Where it says something like "boot menu", "boot priority", or something like that. Make sure USB Flash Drive is the first priority.

7. Save the changes in BIOS and reboot the system

8. Plug in the USB and hopefully, it'll start booting repair tools from the USB stick.

Then follow what I said earlier.

Select Command Prompt. From there, type "chkdsk /f" (without the quotations).

If you're stuck, I'd recommend Brink's Tutorial.

Select Option 2 for the tutorial.

The tool says it's not a valid ISO file, even though it actually is, it's the one from Neosmart, at this point I don't know what to do :S

 

[DeanP]

Download and use UltraIso instead,

Chkdsk /f return:

The type of file system is NTFS.
Cannot lock current drive.
Windows cannot run disk checking on this volume because it is write protected.

Running chkdsk alone returns that everythings fine, no problems found.

Sorry for the double post, but I really need my computer back any suggestions?
