Windows doesn't recognize all my hdd capacity.

I've just bought a new laptop. It was with Linux Boot-Up system. I installed Windows 7 Ultimate x64. Installed all drivers that were on official Acer homepage. Then I saw that the Windows doesn't show all my HDD capacity. It should show 500gb, but it shows only 232GB.
What should I do?

Hello hemis, you said when you bought your laptop, than there operating system was "Linux". Therefore, I think, your hardisk formatted as linux file system base. Windows file system and linux file system is totally different. So when you installed windows 7, at that time you format your c: drive. So widows seven only recognize your c: drive. Because window's seven recognize that file system. Please you format all of other partition on your hardisk by "NTFS" file system. To see your all of other partition go to "run" option and write "diskmgmt.msc" and then press enter. Here you see all of your hardisk partition. Now select drive and right click and then chose "format".

All the best.

Hello Hemis,

Open Disk Management by going to Run and typing "diskmgmt.msc". Select the non C: partition (most probably a linux partition), right click with mouse and select "Delete Volume" and in next dialog box click on "Yes". This will remove the partition and make the space Unallocated. In this space you can create either single or multiple partitions.

To create a partition, right click on the unallocated space and select "New Simple Volume". This will open "New Simple Volume Wizard". Click Next. In this box to create a single partition filling complete unallocated space just click Next. Otherwise reduce the Size in Simple volume size in MB (up-down arrow buttons) or directly entering a value of your choice. Click Next and again Next.

Now select file system as NTFS (preferably for Win 7) or exFAT for a extended FAT partition. Keep default allocation unit size. At Volume Label you may give a name or do nothing. Put a check mark on "Perform a Quick Format" and no check mark on "Enable File and Folder Compression". Click Next and review the settings you have made so far and Click Finish to exit the wizard. Now in the Unallocated space a partition will be created and formatted with a drive letter which appeared and selected in the wizard.

You may always go back in the wizard before pressing Finish to change any values you have accepted before.
