Unable to Boot from Hard Drive I/O Error and Error 0xc000000f

I have a question: Since you didn't post back the requested picture of the results of PW Partition Recovery Wizard, how do we know the partitions which were deleted were found?

Again, how did you delete these partitions exactly? If they only had the Clean Command run on them then I've never seen the partitions not be able to be recovered using PW. It's a simple undelete operation - you tick the boxes of the deleted partitions and restore them. But we saw no boxes or anything else to judge by.

However if you formatted the partitions then both the partitions and the data are rarely recoverable, almost never. So did you format?

I see you are there.

You are using Hiren's boot CD.

Unfortunately I am not conversant with it. I do not understand why it is showing some 26 drives.

( May be you have to come down to my level of creating a bootable DOS pendrive, from which you can run PhotoRec. Then we will be speaking the same language :))

Anyway, I presume you have created a Recovery folder in an external drive/pendrive.

What is its capacity?

Now shut down your PC #1, plug in that external drive/pendrive, switch on the PC, boot into PhotoRec from your Hiren's CD and let me know what are all the drives seen by PhotoRec in the first Window - complete details.

Today I shall have to run around a lot on Personal work and so my presence here will be sporadic.

I shall still be peeping in once in a while.

The pendrive as you call it is 8GB and I had already plugged it into PC 1.
The first screen shows:
1. 931 Gib HD (Main Drive)
2. The pendrive 8 GB

I am at school right now but i have left the computer on at home showing the data from my above post.

I did NOT format:
Here is what i did clarifying the best i can:
First: A problem with the hard drive (Error occurred after computer restarted from a Check Disk Scan), recieved Error 0xc000000F "Boot selection failed, a required device is inaccessible."
Second: Tried to fix it, ended up using Windows Recovery CD > Open Command Prompt> Diskpart>ListDisk>Select disk 0>clean>Exit>Exit. Then Shut down the computer.

After realizing that i just erased data that was already inaccessible i searched the forums and eventually posted.

I could not take screen shots from DOS (that i know of) and i posted the results of the PW in a previous post they were:
1. Reserve Partition size 100MB
2.Boot size: 3.01MB
3.Boot size: 3.01MB
4. Boot size: 3.01MB
5. Boot size: 3.01MB

(I did not tick the box to restore any of those.) Is that what I should do?

This is why Jumanji asked you to post a picture - taken with a digital camera, with file attached using paper clip in reply box. If you had questions about how to do this then always ask back.

These results you report above are all the PW found, after both the quick and full scans? I don't understand why if you only ran the Clean Command the partitions are not there to recover unless you or PW are reporting the sizes wrong.

I'm sure I don't have to remind you that running the Clean command was totally reckless and likely forfeited your data on some random whim that had absolutely no basis whatsoever. Actually its worse than random because its the command that one uses to deliberately delete everything on the drive! Why would you do this?

Check once again that there is no more found by PW Wizard than the 112.4 mb shown. Go ahead and tick all boxes for what it did find to recover it to see if it perhaps is misreporting and will actually will recover all data. Then browse in with Win7 disk to see if you can find the data. Is it able to detect the OS in "Repair My Computer?" If so you can attempt Startup Repair - Run 3 Separate Times confirming first that System Reserved is Partition Marked Active .

I can't recall a time that PW has been unable to simply undelete partitions that had the Clean Command written on them. It's a mystery. But if it won't then continue with data recovery.

greg, I also do not understand how his file system got damaged or disappeared if he had only run the clean command.

It it had not disappeared then PW would have definitely found it from the first sector of that partition where the partition boot record exists, just as it found the System Reserved partition.

Though the OP had not provided a snapshot, he has confirmed that even after a full scan he could see only the System Reserved Partition and four small boot partitions ( Which is an anamoly PW most of the time comes with and should be ignored.)

Even if the Filesystem has been damaged or has disappeared, and even if that main partition has been accidentally deleted including the Partition Boot Record, PhotoRec should be able to recover/ reconstruct his data. So I am working on that premise.

The only problem now is that with him using Hiren's CD we are not talking in the same language. :)

Hi @6arret, I just now created a bootable MSDOS pendrive with Rufus, extracted the zipped Dos version of Test Disk Dos/Win9x and copied all the files into that MSDOS boot pendrive. I also created a Recovery Folder on a 750GB external drive.

Shut down the PC, plugged in the MSDOS pendrive and also the 750GB external drive booted from the MSDOS pendrive, against the C: > prompt typed photorec.exe [ENTER] and here is the first screen.



It shows my 16GB MSDOS/Test Disk pendrive, my 750GB external drive into which I will copy the recovered files, and my 500GB System drive from which I want to recover data.(identified by their capacity)

I would now select the 500GB system drive and go ahead with recovery.Destination the Recovery Folder on the 750 GB external drive. I shall not do anything with the 16GB pendrive from which I booted.

So if your first screen shows the internal drive from which you want to recover and the external drive to which you want to copy the recovered files, rest should fall in place.

(This post I started off long back and after all distractions in-between could complete only now. Hope it falls in place. (I see some conversation has taken place inbetween.))

Thanks, I just wanted to make sure both OP and PW are reporting the PW findings correctly in the absence of a picture. If you think that's all that can be done now with PW, then please continue with the data recovery.

First Screen appears OK. Disk 80 1TB is the internal drive from which you want to recover files. Disk 81 is your 8GB pendrive onto which you want your recovered files to be copied. Right ? Fine then.

First Screen: Highlight (select) Disk 80 [Proceed]

Does the second screen say "Please select partition table type. press Enter when done."? Yes/No

(Here you will select [Intel] Intel/PC partition and press Enter. In case this screen does not appear, it could signify that Test Disk/PhotoRec does not see any semblance of any type of partition existing. And without inputting the partition type/file system, I doubt whether it will be able to reconstruct the files. This is the first of its type I am seeing and so I am only guessing it to be so. And so we shall continue and see what happens.)
So now you get into a screen which says
P Unkown start:0 0 1 121601 end: 80 63 Size: 1953525168
[search] [options] [file opt] [quit]

Here you should highlight/select [file opt] by using the right arrow and press enter to get the file options screen where you will deselect the unwanted file types and select only the file types you want to recover.

In case you do not get this files option screen, we have to close this as an unsuccessful attempt, whether you like it or not and whether I like it or not.

and look out for some other file recovery process.

If everything goes fine and you come to the stage where you have to select the destination, exercise caution.

By manipulating the up and down arrows and left,Right arrows you should be able to change between directories and drives. Be sure to select your 8GB pendrive and not your system drive.

If it is the root of your 8GB drive or you had created a Recovery folder on your 8GB pen drive and can get into that folder, which will be shown on the screen, give the C (capital C) command to write/copy into that.

To make sure only I had advised you to create a Recovery folder on the drive into which you want to copy since untitled ROOT can be deceptive.
