    If you've lost the partitions on the disk, you could try using Partition Wizard Bootable CD or Bootable Flash Drive to recover the partitions...

    @GMan: What about the data that was in my D, E & F drives, would that also be available in the Windows.old folder?

    I would like to follow your recommendation but at the moment I do not have a DVD writer available on a functioning laptop to burn the .iso. So, is it okay to proceed without the SP1 version?

    @Calico: I'll try to recover the partitions thought these options and revert.

    Of course. I then recommend you install SP1 from Windows Update, which will take a little time.

    Your other partitions will not be affected when installing Windows to the partition you already had it on. They will be available immediately when getting back to Windows desktop, unless you've already done something to ruin them before while trying to make the USB.

    You can boot to GParted to have a look at how your partitions currently are, but for that, you'd need to also make a USB or CD installer.

    -----

    And to be clear about something before: You can put Windows 7 on USB to install from, but you can't install it to a USB stick and use it like a hard drive to run Windows normally.

    I had 5 partitions on my 320GB drive before this happened but now when I got into the Win 7 installation's Command Prompt only a single ~320GB partition of type RAW is being displayed. While trying to do a custom install aswell only a single partition is being displayed. Hence I'm a bit concerned if those partitions are still available.

    Does this mean the partitions are no longer available/corrupted?

    The Bootable Flash Drive suggested by @calico seems to be available only on the paid enterprise edition of the Partition Wizard!

    Am in the process of dowloading GParted...

    Unfortunately, your partitions are all messed up. You can likely recover/restore them somehow, but I haven't needed to do anything like that in a real long time so I can't make any suggestions how.

    Some 3rd party software will be able to do it. GParted might even be able to do it, but don't quote me on that one.

    In the worst case scenario though, yes, it is possible that they can not even be recovered, even with tools that can do so. If the data is important to you, I would clone the drive before doing any commands to it at all. This way, you have a backup to try with after (after then backing THAT up.)

    You can put the drive in a desktop and boot to Clonezilla to clone it.

    This might actually fix it but I dunno: MBR - Restore Windows 7 Master Boot Record - Windows 7 Forums

    Like I said though, anything you try, I'd backup the drive first.

    If you're unable to create a boot CD, It's still possible to mount the iso on USB and boot from it, you'll just need a little preparation.

    1. Download RMPrepUSB
    2. Install and run
    3. When the dialogue opens, choose 'Prepare Drive'
    4. Set the parameters as seen in the image
    5. Select Install Grub4Dos
    6. Open the USB/Grub folder
    7. Edit Menu.lst with a text editor
    6. Add the following at the bottom of the file

    title Partition Wizard
    find --set-root --ignore-floppies /pwhe7.iso
    map --mem /pwhe7.iso (0xff)
    map --hook
    root (0xff)
    chainloader (0xff)

    7. Download the Bootable CD
    8. Copy the ISO to the root of the USB (not the Grub folder)
    9. Boot from the USB and select Partition Wizard

    The issue has been resolved. This is the sequence of steps that I had followed-


    1. Created a bootable USB following the steps outlined at
    Hiren's BootCD From USB Flash Drive (Pen Drive) www.hiren.info


    2. Copied all the applications from Hiren's CD onto the USB
    Hiren's BootCD 15.1 - All in one Bootable CD www.hiren.info


    3. Booted the troubled system into Mini XP using the bootable USB


    4. Used Partition Wizard (bundled into Hiren's CD) to recover the partitions


    5. Ran Win 7 installation DVD's Startup Repair twice to restore/fix the boot sector


    The system is now back to normalacy with all the data intact.


    Thanks calico, GMan and all others who have contributed to this forum for your help!

    Awesome. Very glad to hear it. You know what the funny thing is? About 2 minutes before your post just now, I was reviewing the thread for the heck of it - and then I see your post now like magic.

    haha great - enjoy! And excellent job, Calico too.
