UPDATE:

 

I was able to find the version of Windows that I had purchased a couple years ago:

 

Microsoft Windows 7 Home Premium with SP1 64-bit Operating System (PC)

 

This was upgraded to Windows 10 after a few months, but my only concern is the 'SP1' portion. Does this cause any issues with the suggestions listed below (I'm not sure what this falls under in terms of OEM/Retail)?

 

Thanks again.

Hi everybody,

 

Recently due to a few months worth of PC issues, my hard drive has seemed to come to a sudden crash and wont let me login into Windows 10 (Home Edition 64-Bit) anymore. Every-time I launch I get a stop code of: '0xc000021a', or a loop of Windows' 'Automatic Repair' whose recovery/reset options have not been very successful.

 

I've decided, after trying numerous ways to recover my hard drive, to purchase a new one as I didn't have any important files on my current HDD - just the operating system. But before I purchase this new hard drive, I was curious if there was any way I could transfer Windows 10 over to the new hard drive without actually being logged in. I'm not sure if it was a retail or OEM license, but I'd really like to transfer it however possible so I don't have to spend ~$100 on a new license.

 

I don't have the full specs of my HDD, but I do know that it has 1TB storage and 7200RPM. This also goes for the new HDD I plan to buy.

 

Thank you,

 

vinnishi.

If this was an upgrade from a previous OS then the license is on Microsoft servers. If Windows 10 came pre-installed on the computer then the key is in firmware. 

 

Either way you can download Windows 10 using the Media Creation Tool which will allow you to create a DVD or USB flash drive. When you reach the screen asking for a key click next. I don't believe a HDD change is enough to disable your activation if this was an upgrade.

That sounds good, but the only issue is I don't believe I have the key written down. I know I could find it on my specs page if I logged in, but that's obviously not feasible. Is there a way I can retrieve this key so I can reuse it in the media creation tool?

It doesn't matter how Windows 10 came to be on any machine, provided it is a legal and activated installation, you can always reinstall Windows 10 no matter what OS or OSes might have been installed on the machine subsequently.

 

OEM licenses are kept by Microsoft servers just like retail ones are.  So long as the motherboard in the machine remains unchanged and you had a activated copy of Windows 10 on the machine at one time you can replace virtually any and every other component of the machine you wish and still reinstall Windows 10 later.

Thank you all for the helpful responses.

For 100% clarity:   You do not need to reinstall anything related to Windows 7 at all.

 

1.  Go to the Microsoft Windows 10 Download Page  

 

2.  Download the Media Creation Tool

 

3.  Use the Media Creation Tool (MCT) to download the Windows 10 ISO  (I suggest you actually save the ISO file rather than use the MCT to create a bootable USB drive.)

 

4.  Burn the ISO to optical media (if the machine on which you have the new drive and intend to load Win10 has an optical drive) or use Rufus to create a bootable USB drive.

 

5. Boot up the machine on which you intend to install Win10 after having placed the device on which you have bootable Win10 media ahead of the HDD in the boot order.  I am presuming you know how to get into UEFI/BIOS to do this.

 

6.  Follow the instructions in the Windows 10 installer.  You should not be asked for a license/product key.  If you are then just hit next; it will be found automatically for you if the machine previously had a legal copy of Windows 10 running on it.

Thank you so much for the in depth instructions, I really appreciate the help. My new HDD will be coming in tomorrow, and I hope this will fix my issue!
