    Windows 8

    Help please, novice error committed

    I'll cut a long story as short as possible.

    I was running a digital audio workstation with Windows 7 and decided to install Windows 8 on the same hard drive.

    After about a week of tediously installing about a million programs and plugins and satisfying myself that everything worked, I wanted to remove the old version of Windows 7.
    Not sure of myself I asked my brother who told me simply to "just.delete the ' Windows.old ' folder"

    So I did but, apparently, I should have known to use the disk clean-up utility. My brother says he was stressed out at the time or he would have warned me.

    Anyway, I restarted.Windows a while ago and was confronted by the message "disk read error".
    Obviously my boot sequence is still looking for the Windows.old folder.

    I really do not want to reinstall Windows, and presumably all my applications, so could somebody please give me some alternatives?

    Hi Big P,

    Now, I'm no expert but I'm having trouble directly associating your act of deleting that windows.old file causing a disk read error. However, since you haven't provided your specs, I have no alternative suggestions at this time but if it is a manufactured system build, you might want to see if they have any built-in diagnostics that you can run.

    Also, could you please confirm that you upgraded from Win 7 to Win 8 and that is why you had the windows.old file present?

    Hi Big P.

    Welcome to the forums!

    I don't see any reason why deleting the windows.old folder will cause you to get a "disk read error". I know you should run a scan on your disk to see if there are any corrupted files on your computer. Perhaps one of the Windows 8 gurus here can tell you how to do that as I am not really all that experienced with Windows 8. You can try googling how to do a scandisk on windows 8 in the meantime.

    Good Luck!

    Just deleting the Windows.old folder would not cause this. The Windows.old folder is just a backup of your previous install. There isn't anything in there that your current install needs to run.

    They are all correct. Deleting the Wondows.old folder did not cause this issue.
    Disk Cleanup does the exact same thing, so there would be no difference between using either method.

    I would try the repair advised above.

    Also, if you can get the make and model of your Hard Drive, I would download their Diags and run them to see if the HDD is bad
    Keep in mind that Hard Drives can go bad at any given time,, from 5 min of use to 30 years. There is no telling when they can or will go bad.

    Well, I believe your account could be correct. I think I remember seeing a situation in Windows 7 where the system was set to boot through a Windows.old folder instead of the current install. I have also seen installs that needed the DVD in the drive to boot.

    Hopefully, running a repair will help your situation, but if it doesn't, let us know. If it tells you a Restore is needed, first try cancelling out of that and let the system reboot. There are some situations where Windows 8 does not know it has actually done the correct repairs.

    If it doesn't work, I would suggest either using Diskpart from the Recovery Environment to check the drive for partitions or a Third Party partition manager, like Partition Wizard. Having a good picture of how the drive is set up could be helpful. It may take something as simple as a Bcdboot.exe command to get the system booting again.

    Also, make sure your bios is set to boot to the correct device.
