Firstly I backed up & recovered all data from missing partitions with the help of Easeus recovery wizard. then ran windows setup. I setup it showed only C drive, then i formatted it & deleted the partition. Total HDD size was only 35 GB. Then restarted windows setup, then it showed one missing partition (D). Then I formatted this partition and deleted it, So unallocated size became 135 GB. Then I again repeated the above step & finally E drive also came. then formatted it deleted it, to till then I got the full storage of my 250 GB HDD, After that I partitioned again , installed windows. Now its working fine.
But till now I couldn't find the reason behind all the mis-happening.
