Reinstalling Windows 10 from a partition

I have a Compaq pc that originally came with Windows 7. I had problems with it and installed Windows 8 on a separate partition. When Win 10 came out, I beta-tested it on the Win7 partition. I ended up deleting the Win8 installation and keeping the Win10, but I have been having problems with it.
Malwarebytes found a myriad of problems.
In the old days of Windows98, I got in the habit of partitioning my hard drive so the OS is separate from the personal files. I currently have 4 partitions on my HD: The OS on C, recovery on D, (E and F are DVD drives), G is Files and H is extra, where I used to have Windows 8 installed, but which is now blank. I would like to copy a program to H that I could boot to that will let me format my C partition and reinstall Windows 10 fresh. I would appreciate anybody who has a link that would help me. Thanx!

Hello and welcome to the forum.
The first thing you should probably consider is that.....
The task you describe will not protect you if your hard drive suffers some catastrophic failure as your "recovery partition" will be on the hard drive that has failed.
To make another partition on your system drive "bootable" will require the use of a third party product. Something like EasyBCD.
Your best bet would be a more conventional approach
Acquire the latest ISO for Windows 10 from Microsoft
AND then....
Once you have downloaded the ISO you can use ImgBurn to burn it to a DVD
Rufus to burn it to a USB ThumbDrive
Boot your computer with one of those.

IF you decide to go ahead with your original idea this may help you with that pursuit

If you go the Install Media route, during the install you can delete or reformat partitions. You might remove the critical partitions for Windows and reinstall back in that space. You would need to remove two partitions for a Legacy install and 4 partitions for a UEFI install, which yours is probably not.

If you wanted a Partition manager to make changes, there are some which are bootable so you would not need to install something on your empty partition.

There are also some versions of anti-virus software that can be run during a boot to clean out anything hiding in that process.

Does Malwarebytes find any viruses on partitions other than your OS partition?

And as Trouble mentioned, an older drive can begin to fail and show all types of problems.

A picture of your Disk Management window can always help in these situations.
