Why is my system not showing my hard disk?

Huma August 25, 2012

I successfully made a bootable USB using the instructions at //www.makeuseof.com/tag/usb-installation-disk-windows-7-extra-software/ (the comments are closed there). The OS on my system (Win Vista) got corrupt and my DVD drive is also not working.

I changed the boot settings and was successfully able to boot it from the USB drive. The Windows installation started but when it asked for the target drive it is not showing my hard disk partitions (which were 4 in number). Although I can see the hard drive in the BIOS setup. Cant make out what the problem is.

    Hello, try easus data recovery wizrd professional:
    try it, is free trial to download. That was the only app that worked when I find in troubles. It is capable to recover deleted files too.
    I'd suggest you to run an antivirus scan after the recover.
    Let me know if it worked; if not I'll help you; contact me on twitter: @cypherinfo
    If you do not have access to your hard disk may be: it is a boot disk; so when you plug it windows cannot recognize it: you have to access it and change not to boot disk; the other one is you have to assign it ownership and admin permissions; right click go to security tab, click advanced under the Permissions for SYSTEm and go on.

    Thanks everybody. I think there was some problem in the hardware connections. I reconnected everything on the motherboard and it started showing my hard disk :-)

    Perhaps, the windows setup has changed the partition from primary to system partition, 'cause thats what happened to me. I got a paragon disk and copied the data in the drive to external drives. You can also write cds with this. then re-install the window by complete formatting the HDD.

    Read the above comments that maybe can help!
    I would also recommend to check this partitions using linux. If they don't show there too, probably it might be a driver corruption...
    If you see them using linux and can't find any solution, then, I would consider booting with another system (linux will be better), and format your hard drive. Than, after formatting, clean install your windows again.

    If your hard drive don't appear in other os too, and you don't find an answer here, I would consider going to a computer repair shop...
    Hope you find an easy solution here, though!

    perhaps partitions were erased and become one big hard drive?

    boot on Hirens boot cd
    launch mini xp and see if your partitions are there.

    perhaps the letter assigned to the partitions were somehow removed.
    Assign, change, or remove a drive letter
    boot on windows and choose command prompt option to assign letter to partitions

    Can you see the drive(s) in Disk Manager?

    Right click on Computer select Manage then Disk Manager.
    Let us know so we can advise you further.

    The only times I have seen this is when the partition table is corrupt on the drive or when the partitions are ones Windows does not recognize (ext4, etc). Can you see the drive and partitions when booting a Linux LiveCD? Are you using hardware RAID? If you are using hardware RAID, you may need to install the proper drivers so the installer can see the drive(s).
