How to completely remove windows 8.1

[Sam172]

I am getting rid of my old PC and I want to completely remove Windows 8.1 64 Bit OEM so that I can install it on my new PC. Could someone give me a step by step run through on how to uninstall the OS from my PC (or link to someplace that does)?

I do not understand this... are you trying to take your current OS and put it on another PC?

I want to know how to uninstall my OS.

Let me get this clear:

You want to delete the OS on this computer, and leave it with nothing at all? Be aware it won't boot to anything but BIOS.

That is exactly what I want. Can you help?

Do you have a Windows 8 install disk lying around?

I have the original disk I used to install it (Windows 8.1 64 Bit OEM).

I have the original disk I used to install it (Windows 8.1 64 Bit OEM).

Remember, this will delete ALL personal files; everything.
Also, confirm there is ONE hard drive installed in this computer and that ONE hard drive has the operating system you want to delete. If yes, move on.

Boot from the disc and go through the menus as if your installating until you come across "Upgrade" or "Custom" installation. Select Custom installation, and click the circled object shown int his photo:

After that, select the first partition on the list and press delete. Do the same with all the other partitions until it just shows something like this:
698GBs Unallocated

Once you're done shut down the computer, restart it, eject the disc tray, take disc out, shut down, done.


Then you ought to be good to go.

Thanks for the help, but I'm having trouble figuring out how to find the boot from disk option. (My motherboard is a Gigabyte AMD Motherboard GA970 A) If you could help with this as well I'd be extremely grateful.

Are you in BIOS? is there a tab called Boot? If so, go to that and let me know if there are any options like "Boot Override"

this is what I see:

Please select boot device
UEFI: ST000DM003-1ER162
P2: ST000DM003-1ER162
SATA PS: HL-DT-ST BDVDRW UH1
UEFI: HL-DT-ST BDVDRW UH12NS30
Enter Setup

Which should I choose?

 

[jaguarman]

My guess is
UEFI: HL-DT-ST BDVDRW UH12NS30


Let me know what happens.

 

[Sam172]

UEFI: HL-DT-ST BDVDRW UH12NS30


Let me know what happens.

I am given the option to "Install now" or "Repair your computer"

If I click "Repair your computer" I am given these 4 options:
Continue (exit and continue to windows 8.1)
Use a device (use a usb drive, network connection, or windows recovery DVD)
Troubleshoot (refresh or reset your pc, or use advanced tools)
Turn off your pc

Hmmm...scratch that. what is your computer model or is it a custom build?

Start the computer and press F12 repeatedly, a boot menu hopefully will come up. Select the DVD drive from the list...might say something about LG if it's an LG disc drive.

Select

and if it asks about entering setup, select that.
I will be back tomorrow to help further.

Apologize for the delay Sam. Do you mind posting a screenshot of the boot menu?
