I have a 200 Gbs HDD with vista and I decided to install Ubuntu 12.10 over it, but I found that it erased all the partitions and data and showed the file system as 198 GBs, so I tried to reinstall the windows then to recover the data but I couldn't, and after reinstalling Ubuntu and recovering some files it shows file system of only 186.3 GiBs, and some one told me that it's the same as 200 GBs
Now I totally removed Ubuntu and installed win 7, but it also shows me the partitions and the space as 186.3 GBs not GiBs with about 3 GBs missing at each partition
How can I make use of all the 200 Gbs and make windows shows the right HDD capacity???
Thanks in advance for your help.
