  1. bad sectors on hd and win 10 wont boot now


    Hi All,

    I need to low level format my hd as it has bad sectors on it and then install win 10 home. Win 10 is not booting and says no system found.

  2. HDD Bad Sector

    Hi Nataniel!

    I am not sure what your question is exactly, but one thing I'd recommend for sure will be to look for a replacement drive since there is already a bad sector on your current one.

    Basically there are two kinds of bad sectors - hardware and software:

    • Hardware ones are caused by physical damage or becoming magnetically fixed, and they are unrepairable. In short, once they appear it's only a matter of time (no way to say how long) until the HDD fails.
    • Software bad sectors on the other hand occur when something called an Error Correction Code (ECC) doesn't match the contents of the hard drive. These can be repaired by overwriting the data on the drive with zeroes (a.k.a. low level formatting) and sometimes
      by running a **chkdsk [write the letter of the drive:] /r** in the CMD.

    As for getting the information from the drive if one of the partitions fail, most likely you won't be able to, which is why I'd suggest to make a regular backup of your most important data.

    Hope this helps and feel free to ask any questions you may have.

    Win 10 HD went BAD and now cannot dual boot after attempting restore image

    HD Fail, need to restore dual boot system Win 10 and Win 7

    1) Installed Win 10 from iso in April 2016.

    2) Original system was Win 7 Home Premium so this resulted in a dual boot system which has had no problems.

    3) A few days ago received notification in POST that the HD containing Win 10 OS was bad.

    4) Made image of Win 10 partition on external USB HD. Also tried to use Paragon Back Up and Recovery to create an image but this failed with Disk I/O error.

    5) Used Hiren to test HD with HD regenerator which showed multiple bad sectors which were recovered. But due to long time, only tested the first 140GB which should have covered OS partition.

    6) Installed SSD and formatted from Win 7 system.

    7) Tried to restore Windows Image from 4). But image not locatable and worked through all the options to try to restore.

    8) After installing Win 10 originally, I made an image using Paragon which was the bare bones Win 10 immediately after installation. I used this to restore Win 10 onto SSD. Network was disconnected for the remainder of these steps since I did not want to complcate
    the issue by Win 10 trying to instal updates.

    9) System would not dual boot and had to choose "Use another OS" which took me into Win 7 which was OK.

    10) Removed Win 7 HD so only system was the restored Win 10 on SSD. But this failed to boot into Win 10 with File \Boot\BCD missing.

    11) Used win 10 recovery CD to repair Start Up and Win 10 finally booted up and seemd OK.

    12) System then shut down with Critical Process Died error. Rebooted back into Win 10 and seemd OK but eventually another critical process died message.

    Questions :

    1) What is best way to get back to dual boot system ?

    2) If I do a clean install from the Win 10 iso (which seems to be the only option left), will this incur a charge from Microsoft since I am past the date for the free upgrade.

  4. bad sectors on hd and win 10 wont boot now

    Win 10 HD went BAD and now cannot dual boot after attempting restore image

    A few days ago received notification in POST that the HD containing Win 10 OS was bad.

    Made image of Win 10 partition on external USB HD.

    -> That's like taking out a fire insurance policy after noticing the flames in the roof of your house.

    To restore dual booting, do this:

    • Create at least two disk partitions.
    • Install Win 7 in the first partition, using your Win7 installation DVD.
    • Boot the machine with your Windows 10 media creation tool and install Windows 10 in the second partition.
    Since your machine already had Windows 10, it remains registered and you will not need and product key.
