Replacing laptop internal hard drive

This laptop had slowed down.  I knew I needed to replace the internal hard drive, but wondered if the Windows 8 DVD I had from before would work.  It worked last time when a new drive was installed in 2014.  But will it work again.  Won't it say that the operating system has been used before? 
I gathered all the information about this machine from old records.
Here is the whole deal:

November 26, 2011-Inspiron 14Z ordered; $757.46; 8G RAM; expected shipping date 12/6; expected delivery 12/9; computer received on Saturday, 12/3; used easy transfer cable to transfer data to the new laptop.

The laptop has Seagate Momentus 7200 750 GB 7200RPM SATA 3Gb/s 16 MB Cache 2.5 Inch Internal Notebook Hard Drive.

Dec. 1, 2011-ordered USB enclosure for laptop hard drive $9.xx.

Dec. 5, 2011-Met with MA; visited Microsoft store; bought Windows 7, MS Office 2010, and Web Expression.

Laptop hard drive changed on Nov 7, 2012.  It is a good idea to change the internal drive in a year or two, before a catastrophic failure.  Have learned this while reviewing ISO9000.

April 28, 2913- ordered laptop battery online.

FEb. 12, 2014--Having second thoughts on buyin a new laptop, this one's LCD screen has given problem before, cannot afford a breakdown; buy new, then add 4GB RAM to make it 12GB RAM, ;at Dell.com; the top of the notch lapotops have i7 processor, 8 GB RAM, 1 TB HDD; this one has i5, 8GB, and 1 TB; no need to buy new computer; just buy new hard drive.

Feb. 26, 2014-This laptop [Dell  Inspiron 14Z, i5 processor, 8 GB RAM] is slowing down.  At Fry's; Saw 1 TB 2.5 inch 7200 rpm, 16 MB cache Seagate SATA hard drive; it is now time to change the hard drive, talked to MA [Microsoft] on the phone; later sent him email to get me Windows 8 Operating System; Getting new HGST Travelstar 1 TB, 7200 RPM, 6 GB/s 32 MB cache, price at Amazon is $84.99.

Jan. 4, 2016--At Amazon.com, ordered Inspiron 14 Z 65 Wh laptop battery for $27.42

Jan 20, 2016--New keyboard ordered for this Dell Inspiron 14Z laptop (this laptop was bought on Nov 26, 2011, almost 5 years ago). Laptop is fine; processor (i5) is only one generation old (currently Dell selling i6), RAM of 8 GB is still double of what most laptops come with. It was just he keyboard giving me a lot of problems: top row keys, Q through P would stop working, and then start working after some time. Thought it might be a driver problem, but no yellow sign visible by the keyboard, under device manager. Finally thought of getting a new keyboard; got the best deal at ebay; ordered one (total $10.07).

Keyboard replacement worked.  Everything is fine.

Oct. 2, 2016--This laptop has been shutting down unexpectedly.  Do this: 1. Use compressed air to blow dust, 2. Buy new hard drive and replace it (but then how to use Windows 10?).

Apr 16, 2017-Is the hard drive of this laptop going to give up?  At times it is very slow; may be because of the hard disk space used to the maximum (with only 65 GB free).

Apr 16, 2017--Have to decide.  Buy new laptop vs. keep old laptop but make updates.

New Dell Inspiron 17 5000;  i7 processor; 8 GB RAM; 1 TB HD; with Windows 10, but MS Office only 30-day trial; $549

Issues: Where is the Windows 8 OS software?  Where is MS Office 2013 key? [need key after downloading from their web site.]

August 3rd 2017. Thursday. It is absolutely great that after a little effort I found all the software I need when I get the new hard drive for my laptop. All the important software including the operating system were in a blue bag. It is a Microsoft bag that I got from the Microsoft store when I visited my friend MA who was working there at that time. This blue bag has the AutoCAD 2011 software; it has the Windows 8; MS Office home and student 2013. I have the Windows 8.1 Pro which was the latest operating system at that time and it has both 64-bit and 32-bit DVDs and then there's this key which has the product key information on the back which will be used after I install it. The only problem is that this is not the latest operating system and also the one that I installed before. Will it work?  When it was installed on this drive, one day it suddenly updated to Windows 10--so now that I am using it again, will it not let me do this?  That is a very big question.  I do not have an answer.  In the same blue bag I have the Corel Video Studio CD. And then I have other information about drivers and utilities needed for the Dell laptop.  I think this will come very handy because a lot of drivers are needed once I install the new operating system. The same blue bag also has other CDs that were never used. There's one called Microsoft expression Studio; then it also has office home and student 2010 which I think was used many times. 

August 6, 2017.  Have found this great article on how to transfer Windows 10 to a new drive.

https://www.microsoft.com/en-us/software-download/windows10

The information in the article says I need a high density DVD [of more than 8 GB capacity—the ones I have are 4.xx GB] or a USB drive.

Looked in my stuff and very fortunately found a 75 GB drive from around 2007 (?).  Was able to connect the drive to this laptop, but then noticed the power supply to the drive.  Looked for the right power supply but could not find one in my arsenal.  When I came back to this laptop, the drive had opened up on the screen!!!!  It is completely empty: all 75 GB of space.  Now going to do what the article is asking me to do.

The above did not work!

August 6, 2017.  Tried creating Windows 10 back on the 75 GB USB drive.  This drive when connected to the left side USB port (USB 3.0?) works fine, but when connected to the right side USB port (USB 2.0?) starts giving a repeated clicking sound as if the drive is trying to read but is unable to do so.  Used the drive in the left hand side port, but the process did not work. Got an error message.  Error code:

0x80070002-0xA0019

Read online about it; found out other people having same problem.  On one recommendation, formatted the 75 GB drive to FAT (actually xFAT), and then tried to make a backup.

August 7, 2017. Checked this morning.  The backup on the 75 GB still did not work.  What are my options?  First, Keep trying the 75 GB drive. Second, use the 1 TB Passport drive; remove data on it and use it to make up the back up drive. Third, When the new drive comes, try to install Windows 8 on it, using the CD I have. Fourth, When the new drive comes, use that as an external device and make backup on that drive, and then use the drive internally.  Fifth, Get a double layer DVD and try to burn the backup DVD.

 August 8, 2017.  Received the new drive.

Aug. 9. New 2 Tb drive installed. Two mishaps.  Screws fell down. Later, compressed air caused moisture; it had to be dried.

But good things: 0. New Drive worked fine 1. Windows 8 DVD from before worked, 2. No drivers were needed to be installed. Did the machine get the drivers directly from the MS site?

Lesson for next time. Keep the Microsoft username and password handy.  Right after Windows installation. Connect to the Internet. And then install MS Office (office.com/setup) [username and password needed; MS office key needed]; with MS Office, can open Excel file and look at the username info needed to install other things.
