Fix: 0xc0000098 Error In Windows 8

I have installed the Windows 8 in triple boot with Windows 7 and Ubuntu 12.04 a couple of weeks ago. Everything was working fine like a charm. But when yesterday when I booted up the laptop. I came across this error and thus unable to boot.

Windows Boot Configuration Data does not contain valid OS Entry

Then I checked the installation parameters and found that everything was set correctly. I tried to troubleshoot it with the Repair Disk but with no success. Finally I got it fixed and the way which worked for me, is being shared below, so that others can benefit from it.

Troubleshoot 0xc0000098 Error

Basically you need to performed a chkdsk operation to sort out the issue in such cases. But when I tried this, it doesn’t work at all and I  received the following message:

The type of the file system is NTFS. Cannot lock current drive.

Then I came to know about the integral workaround, which goes like this:

1. Boot into safe mode with elevated command prompt.

2. Type DISKPART command. It will launch the Disk Partition utility.

3. Now type the list volume command. It will list the volumes on system. Carefully note the volume for Windows 8. The image shown below is just for convenience of users for applying commands.

4. Moving on, type select volume ### where (### represents the drive number in which your Windows is installed. It’ll select the volume in which you are getting the error i.e. the drive for Windows 8.

5. Finally apply the following command :

attributes volume clear readonly

Applying the above command will fix the basic writing problems with the drive associated.

6. Type exit to leave diskpart utility.

Thus the manual workaround is over. Now its time to check for disk errors, to do that type:

chkdsk /f

chkdsk /r

That’s it. Now the Windows will ask you to reboot and on reboot it will fix the issue and make the way for normal boot.

Note: The Command applied in step 5 will work only if your system drive is infected and you’re getting errors on it. On a normal system, on which you have not experienced such error, applying the command of step 5 will yield a bunch of command list, but will not make the default drive writable.

If you have also received this error, feel free to share your problem. Different systems may need different fix for same issue due to configuration parameters. The way shared here just worked for me and I hope it works for your too. If it doesnt, you might want check out if running Startup Repair helps you.
