Why does Windows 7 not recognize my new hard drive on which I installed Ubuntu?

Divyam December 26, 2010

I have Windows 7 Ultimate 32-bit. I had bought a hard drive of 500 GB and installed Ubuntu on it. But now Windows doesn’t find my hard drive when I go to My Computer. What shall I do so that Windows finds my hard drive?

    One last thing: In Windows 7 You also need to initialize the disk in "Disk Management" before the operating system will recognize the disk.

    Look in Windows "Disk Management". See if it is sharing a drive
    letter with another drive. If so, there is an option to change the
    drive letter.

    You may have to initialize the drive. Just boot it to windows, initialize the drive and then see what happens.

    Otherwise, you can use a utility called Gnome Partition Editor – check for a command called gparted, or just “sudo gparted” , and this should allow you to allocate / initialize the drive.

    How To use Linux Swap Partition as windows Swap file

    1. Go to the website below, and download the swapfs zip file to a windows accessible folder:

    2. Write down the location of your linux swap partition (for example, mine is the 4th partition on the first drive; /dev/hda4 or (hd0,4). hda=hd0, hdb=hd2, etc... If your drive is sdaX, check your bios settings to determine which drive it is.
    (Do not include extended partitions, only primary and logical).

    3. Extract the contents of the zip file to its own folder, and open up the file "swapfs.reg" for editing, changing the two lines that read "\Device\Harddisk0\Partition1" to the location of your linux swap partition (in my case "\Device\Harddisk0\Partition4").

    4. Copy the driver (swapfs.sys) to "%systemroot%system32drivers".

    5. Reboot, and verify you swap settings under system settings, in the control panel (you may have to turn off the old paging file manually).

    6. Enjoy the extra disk space!

      A swapfs.sys can handle only one swap partition. How can I use multiple linux swap partitions< if I had one?

    Excuse my poor proof-reading skills. The second sentence should read as: "For the most part Windows 7 **SHOULD USE** NTFS..."

    Windows 7 can be formatted in FAT, FAT32 and NTFS. For the most part, there are almost no reasons to format as anything less than FAT32. And preferably one should format as NTFS, since it supports larger files and better reliability.

    Ubuntu and Windows 7 use differing file systems; W7 will not recognize anything other than MS file systems. For the most part Windows 7 NTFS and Ubuntu commonly uses ext3. Special software is required in order for a Windows system to recognize an ext3 file system.


    If you are attempting a dual boot setup, strongly consider EasyBCD, which greatly simplifies the dual boot process. Please be aware that you can damage your system by incorrectly configuring EasyBCD, since it deal with files that are crucial to system stability.


    Good luck!

    Try deleting Ubuntu from the HD. After this, Windows should recognize it.
