Hey,

I recently lost my wallet. My computer was giving me a boot error that it was missing a windows file and could not start up properly. I attempted to repair the file using startup repair and run a system restore, both to no avail. I then proceeded to attempt to re install windows on my drive. The installation was getting caught up on completing installation so I was forced to shut down. So after all this happened I plug in my USB to a separate laptop to check if my wallet is ok; its not. For some reason I dont have the wallet.dat file on the USB with the bitcoin file (dumb, i know). So now I've got a drive that can't boot plus my extra drive (either one could have the wallet.dat file on it) and I'm lost. Im looking for any help I can to recover my coins Sad.

Read some posts and it looks like a member named casascius can help me out, but Im new to this site and it doesnt look like im allowed to PM yet for some reason??
Any response from anyone is much appreciated. Thanks.

@OP: if your wallet.dat is lost, then your bitcoins are lost.

I'm getting tired of this. it's always the same problem.
Either the official Bitcoin client should use a deterministic wallet, or newbies should be directed to use deterministic clients.

but just like car keys or your sanity, they may not be lost permanently, and could still be recoverable.

Remove the hard drive from the computer that isn't able to boot, and insert it into an USB caddy. Hook that up to a working computer, and browse the drives contents and see if you can find the wallet.dat. Good luck!

You might also try this; Make a Linux boot CD (an ISO image). You can download one of many kinds for free. Now boot your computer from the CD. If it wont, you will have to go into the bios and set it to boot from CD/DVD first.
Once booted you may be able to browse the HDD that is in the machine. If you find your wallet.dat file, you can copy it to a USB stick.

Good luck mate. I'm sure it will happen to me one day also.

It sounds like your drive is not completely gone.
As long as you didn't format it the wallet.dat should still be there.
Thus downloading a Linux Live CD (e.g. Ubuntu) and then recover your wallet.dat sounds to me the easiest way.

Check out Cwallet (on this forum). You can print your private keys with it in a nice QR code.

sounds obvious, but don't download it onto the hard drive with the wallet.dat on it.

So point them in the right direction

Your wallet should be located (in Windows 7) at C:\Users\<Your User name>\AppData\Roaming\Bitcoin. Try to use some recover software (like Recuva http://www.piriform.com/recuva ) to see if you can get it back, maybe you can recover it from the pen drive.

Either this, or just hook the hdd to a new working pc/usb caddy to access the files inside. Your HDD doesn't seem to be fried.

this is sort of off-topic, but what do you do when windows 7 tells you access denied on that folder? i was trying to help my brother back up his wallet but a) windows explorer wouldn't even let him navigate to that folder, and b) when i helped him get there via the command line, the copy command told him 'access denied 0 files copied.'.

Is he on admin? If so, he might need to take ownership of the file.

i don't know... he owns the computer, and no-one else uses it... it seems retarded to me that win7 by default won't let you access your own files. i'll check out the link, thanks.

Were you using a bitcoin client when the harddrive failed?  I'd think it could be retrieved..

Can a person run their btc client from a flash drive, and allow all bitcoin directories to stay on that drive? the default is application data folder, I havent bothered seeing how to change it yet..
