Hi Terry - I'm assuming your C drive includes a 'System Reserved' partition?

You can unmark a partition as active using "diskpart" commands. Please follow these steps:

Open an elevated command prompt (run as administrator)
Type in diskpart and press Enter.

Now we're going to identify which partition you need to work with:

Type list disk at the prompt and a list of disks will be displayed numbered starting at 0
Type select disk # replacing the # with the appropriate disk from the list
Type list partition and a list of partitions for the selected disk will be displayed
Type select Partition # replacing the # with the appropriate partition from the list

To unmark the selected partition as active, type in the command: inactive
Exit the command prompt using command: exit
Reboot the system.

Hope that helps.

Of course!! What was I thinking! Sorry mate.

A couple of suggestions:

1) Download bootable MiniTool Partition Wizard, burn the ISO to disc and boot the PC from the bootable disc: https://www.partitionwizard.com/partition-wizard-bootable-cd.html

Or, download GParted bootable ISO here: http://gparted.org/livecd.php

NOTE: I'm not sure if either software includes a feature to unmark partitions as active so it would be a look and see situation.

2) Download a Windows 7 SP1 ISO using the software discussed in this article here: https://davescomputertips.com/easily-download-windows-isos/

Or, if you have a product key, you can download the ISO here: https://www.microsoft.com/en-au/software-download/windows7

Okay, so specific to Chrome.

Download and run the Chrome Cleanup Tool here: https://www.google.com/chrome/cleanup-tool/

Next, reset all Chrome settings: https://support.google.com/chrome/answer/3296214

Finally, scan the system with AdwCleaner: https://toolslib.net/downloads/viewdownload/1-adwcleaner/
