    Restore partition table?


    (copied from another forum location)


    Okay, so long story short I recently tried installing Ubuntu dual boot with my Windows installation as I had done with a previous system. I somehow failed to notice I had whole disk selected rather than the option for partition. Well. Obviously it wiped my whole disk along with my Windows 8 installation. I aborted the Ubuntu install progress right away and shut down, of course it was too late to save everything.

    I resorted to Testdisk. It was able to find my C: (windows) and M: partitions, which I am able to restore in order to copy and access my data, but not simultaneously. It must be only C: (Acer) or M: at a time.

    At this point my data is safe. My only concern now is fixing the Windows installation, I had neglected to create a recovery drive until after this headache transpired, and that was done with my friends Dell machine. I do not have any Windows 8 discs or drives, nor do I know how to aquire it without purchasing, which is not an option.


    I suppose I'd like to know if I'm going to be able to boot Windows again, using testdisk to restore the proper partition table setup and (I don't need M:, it's been backed up)

    I cannot restore or refresh the system via the recovery Usb created on the other pc as it reports the drive is locked.

    Laptop is an Aspire V5-552p-x440.


    I'm doing this from my phone, if any additional information is needed that I missed I'd be glad to provide. Apologies on the messy post.

    Note : I cannot access Acer Recovery

    Hi Welcome to 8Forums,

    You may try to attempt to do a partition recovery using Partition Wizard MiniTool Home Edition or Partition Find and Mount. If both of those applications would not do any help then I'm afraid your best option is to acquire the Acer recovery disc in order for you to restore your laptop in its usable condition.

    I'm unable to use partition Wizard because I don't have a disc drive and putting it on usb seems impossible, especially within Linux.

    Star,

    I copied the following directly from my pdf copy of Windows 7 Resource Kit, and should be similar to win 8:

    "Startup Repair is by far the quickest and easiest way to solve most startup problems .However, if you are familiar with troubleshooting startup problems and simply need to fix a boot sector problem after installing another operating system, you can run the following command from a command prompt (including the Command Prompt tool in the System Recovery tools).

    bootsect /NT60 ALL

    Bootsect .exe is available from the \Boot\ folder of the Windows DVD and can be run from within WinRE or Windows 7. After running Bootsect, you should be able to load Windows, but you may not be able to load earlier versions of Windows that are installed on the same computer. To load other operating systems, add entries to the BCD registry file, as described in the section titled “How to Create an Entry for Another Operating System” earlier in this chapter ."
    Basically, you need bootsect.exe, boot to a command prompt, then run the bootsect command above and you should be good to go if I understand your problem correctly. I did a quick search, and you should be able to d/l bootsect for win8 64bit, and add it to a startup usb drive or something similar.

    If you need further assistance, let me know.

    The command completed mostly successfully but I'm still met with" no bootable device, hit any key " When booting without the HP recovery drive (remember my system is an Acer) .
    A:, and D: completed, though device\harddiskVolume2 got " could not open root directory : parameter is incorrect "
    Sorry for the small replies, still only able to visit via phone

    Do you have access to System Recovery Tools? How did you get to command prompt? (Are you able to hold F8 at boot, or did you boot to a disk/flash?) - I want to know what kind of tools you might have available to fix the boot record, etc., - Microsoft usually includes several specifically for the purpose of restoring corrupted or overwritten boot credentials.

    I am using a recovery usb created on a separate system.

    I've since been able to restore my partition table more using minitool usb (finally) and currently diskpart shows on disk 0 :

    Vol 0 A: ESP fat32
    Vol 1 D: Acer ntfs
    Vol 2 E: Push Button Reset ntfs
    Vol 3 F: RECOVERY fat32



    I'm now able to boot the hard disk to an error reporting a booked Bcd, but attempting repair says system resource not found. I should be able to use alt f10 to access Acer's recovery environment but I'm unable.

    OOps.


    Your best bet is to d/l the 8.1 with update iso ( no idea if you have Core or Pro) .

    Put it on flash drive - (Rufus - Create bootable USB drives the easy way is probably easiest for that). Boot it up and try running startup repair.

    If no joy, then use the generic key to get it to start the install. Go to Drive options (advanced) and delete the first 2 partitions. Install into the unallocated space you just created.

    After it has installed, you can get your oem key from the firmware and enter it in the activation window.

    If the recovery partition has been unaltered, by all means do so. I believe the access to the recovery process is Alt + F10 at boot, it could also be just F10. If unable and your recovery disks do not work, you will have to order a new set from Acer.

    I've looked everywhere for an 8.1 core and I can't find one.
