Windows 10: Remove OS from OLD Hard Disk Drive

Hello,


I installed an SSD on my Laptop. I did a fresh install of Windows 10 on the SSD and formatted the old HDD, but somehow when I boot up my laptop it still goes to the Windows Boot Manager asking which operating system to use. I probably made a mistake because the HDD still has Partitions for Recovery, and EFI System.





Here's what I've done to get to this point:


1. Install SSD

2. Install Windows on SSD using USB

3. Format the Windows partition on the HDD Backups D:\

:)

 

Remove spare hard disk as system disk

Thank you for your reply.

There's a possibility that your HDD was detected as OS drive during the Windows installation. To remove your HDD as system disk, we suggest reformatting it. To do so, please follow the steps below:

• Open Disk Management.
• Right-click on your HDD, then select Format.
• On the Format windows, type your preferred Volume label,
  File system (NTFS is recommended), Allocation unit size (leave as Default).
• Check the Perform a quick format option, then click
  OK.

Note: Please back up your files before reformatting the drive.

Feel free to post back should you need further help.

How to Partiton a Hard Drive in Vista

This is a way to get Vista to see another hard drive that is not associated with the OS. There is some times when your new hdd doesn't seem to want to work well with Vista. But, there is a solution in it.

Open the Computer Management By doing these steps.

• Click on the Start Button
• Click on Control Panel
• Click Administrative Tools
• Double click on Computer Management

You are now in the Navigation panel of the Computer Management.
When in Computer Management, you then have to allow the new drive to be recognized.

• Double click on Storage
• Double click on Disk Management

Now in the middle of your screen there is the layout of the Disk Drives that you have. The drives that are partitioned will show by the drive lettering. The others will just show up as having nothing at all in them. Below that there will be the Disk drives that are installed into the computer. You'll see that the primary one will all ways read as "Disk 0". Then you will have Disk 1 and so on. Under the Disks there will also see your CD-Rom drives.. If there is more then one, it will be labeled the same as Disk drives..

On to the Partitioning of the drive in question.

• Right Click on the drive
• Click to format the drive or Enable Volume. There will be a series of windows that open up. This is Vista's formatting. Just go threw the windows, and make sure everything is the way you want it to happen.
• Once the formatting is done, will take some time depending on the drive size.
• Right click on the drive
• Click on Mark the Partition as Active

After you have done those steps, The drive will be up and running threw Vista.



:Side Notes:
If you are not the Administer to the Os, then you will have to enable it..
You may also want to redo the drive lettering of it all. But, I really don't see a reason to do so. If you do, you have to redo drive paths and so forth.. A lot of work on something so small...
