Hello Arun,

it might be a messed up partition table as far as I can tell. Did you mix Windows and Linux software to partition your disk? I highly recommend a) backup your data b) try running TestDisk or even better, download Parted Magic which has great testing and recovery tools, new versions of fdisk etc, and of cource it includes TestDisk.

Also have a look at this, I don't know if it's exactly the same case though...

Hi Arun_kumar_k,

As I can see that all your disk space has been used by your Windows and Linux install. "Partition 1 does not end on cylinder boundary" as I can see from the output does end the cylinder boundry. But this error is common when you use "parted" utility in linux to create partition and then switch to fdisk for managing them. As I can see Partition 1 is your Windows partition and primary partition as well and the message can be considered bogus if you are able to boot into both of them.

The partition error that you are seeing could be because of the difference between the way Windows and Linux handles partition table. As long as you are able to boot into both of the OSs it should not be a problem. However, if that is not the case then there is a problem.

As you said that you are not able to install linux onto this machine. Are you trying to triple boot? Or you are trying to delete the existing linux partitions and perform a different linux distribution install? If latter is the case then do you not get option to expand hard disk and see the existing partition table? Do you get any error message. Usually during linux install if you are using GUI install then linux launch disk druid for partitioning. Are you not able to do anything with that?

Make sure that you take a good backup before trying anything
