You can download a recovery image from their support page (google is your friend)

Dell are pretty good.

Download Network drivers from their Support page (use your Service Tag to get the right drivers) before you format and put them on a USB key.

Format, reinstall Windows, Install network, go back to their webpage and use the 'Detect' feature and it will find and install all the drivers you need.

I did follow all steps from dell website.

Downloaded on USB drive and when i plug that into the laptop i want to reinstall os, it does not recognize it.

Kept on saying about GPT and MBR partitions.

could not get pass through that.

Now when i plug it in today, i dont even see the option to select my drive to boot from...

how do i start this process form scratch ?

as my usb does not showup on my system

When you downloaded to the USB, did it run any software to make the USB bootable, or did you just copy files to it?

The USB needs to be bootable.

What model is the notebook? I can have a look at the Dell support site.

FIRSTLY - What OS are we talking about? Is that the original OS, if not what was the original OS?

Windows 7

Is that the original OS?

What edition of windows 7, is it 32 bit or 64 bit? What have you downloaded onto the USB??

Is it trying UEFI boot or Legacy Boot (or does it even have those options)?

The dell tools create a bootable USB - is your USB seen in Windows?

Is that the original OS?

 

Yes,

i load my service tag on that dell software and it gave me only one option

Windows 7 Sp1 professional 64 bit

Download size 7.06 gb

 Trouble uploading image, showing the following message for 10 minnutes

Uploading...
No files uploaded

Here is what i see when i tap F12 while restarting

Boot mode is set to: UEFI; Secure Boot: OFF

Legacy Boot:

        Internal HDD

        USB Storage Device

        Cd /DVD drive

       On board NIC

Other Options:

              BIOS Setup

              Device Configuration

              Diagnostics

              Change Boot Mode settings

So when i choose USB Storage device, Next screen shows " Invalid partition table!

Something not right with the USB stick then.

When I had similar issues (needing to create a UEFI boot stick) I used Rufus (free download) to create a bootable UEFI stick, then just copied the contents from the boot dick I already had. If dell offer an ISO (disk image) you could get it to create the stick using the ISO, but I just copied the files over.
