Windows 10: Professional cleaning: what's involved?

I doubt my brother has taken a backup in his life - on this or any other computer ;-)

 

Do you have any local friends that are experienced in working with PCs that could possibly help you along and assist with interpreting the info you're given?

When you’re first getting your feet wet in PC repair, learning from people helping you on the net doesn’t always cut it. I’m not great at explaining things. Also, I’m not an expert by any means so keep that in mind. You never stop learning when it comes to PCs.

You’re fortunate in this situation because you have a PC that doesn’t require any backup and presumably you’re not on a strict time table. Just relax and take it slow.

If you’re still unable to get DBAN going, perhaps it’s best to put that aside and concentrate on getting the Windows 10 install media created. Once you’ve created that, review the instructions for booting that I posted above and see if you can get into the installation setup.

 

This is an old vid, but may be of help. There should be other info available on the Acer Forum or website.

Acer Laptop/Computer - How To Wipe and Restore Hard Drive to Factory Default - YouTube

 

I had a bunch of distractions and got sidetracked with them but now I'm back and ready to work through the instructions I've been given on this thread. But first, I need some clarification.

I think we've established that my brother's computer is running Windows 10 and that he has UEFI.

1. I'm looking at the link that talks about creating bootable copies of Windows on flash drives or DVD - Create Bootable USB Flash Drive to Install Windows 10 Installation Upgrade Tutorials - but I'm darned if I'm clear on which of the many variations on that page I should be following. I initially did the instructions in Option 1 but now I'm thinking I need to do Option 2, especially #6 within that so that the UEFI is handled correctly. Is that correct?

2. I'm still concerned about erasing the hard drive by some method or another but I'm confused about the timing and technique. It seems like there was a concensus reached suggesting how to clean the hard drive when I reported that I couldn't get the computer to boot into DBAN - please correct me if I'm wrong - that included these steps:
==========Boot from a windows 10 installation drive

Press shift+f10 to get to command prompt

Type

diskpart

list disk

select disk n (n is number of drive to be wiped - normally 0 if only 1 drive)

clean all (all does secure wipe - can take a long time - do overnight)

exit exit======

Assuming those are the instructions to follow, I'm not clear on the timing. It seems logical that I would need to do those instructions FIRST before attempting to reinstall Windows. Is that correct?

 

Go to this page and download this tool. Execute the tool and follow the instructions. The tool will walk you through creating the media. Have a blank DVD or a flash drive ready, depending on which method you want to use to install.

Get this out of the way first:

Download Windows 10

 

Many of them will format the drive and reinstall Windows without looking at the pc to see if the infections can be removed without a format.

Some may actually have a look at what's present, even though they probably have no idea what it actually is.

 

Not to turn this into a debate, but I’m of the opinion that unless you’re an OS engineer or a professional security researcher, you don’t have the knowledge or skills to clean malware from an existing OS install and say with 100% confidence that the machine is clean. That goes for me, most people on the net and a lot of computer shops. That’s a very specialized area of expertise.

It doesn’t take an expert to zero a drive and install an OS.

It’s all about what level of risk you’re willing to accept.

 

I second your opinion, fortunately there are quite some people that can actually do this the right way for free. I happen to train for this so hopefully one day I will be able to do this kind of tasks.

Before this goes south ways, please keep in mind I merely answered the OP's question with my opinion and experience with computer stores.

 

Hats off to you. Malware disinfection Is a whole new level of tedium that I care not deal with. You have to really like this stuff to do it.

I’m all for trying to save an install that isn’t related to malware, but if I’m dealing with an infection, it’s orbital bombardment for me. Absolutely no patience for it.

 

I realize you two are discussing important issues related to my issue but I'm still struggling a bit with the questions I asked in post #32 in this thread. I've created the media (on a 32 GB flash drive) to recreate Windows 10 on my brother's computer using my own computer. I put the flash drive in his computer and clicked on Restart (I had his computer on to verify that the Windows version was Windows 10 Home), then started pressed F12. I pressed it many many times from a second or two after I clicked on Restart, and it still booted into Windows 10 and presumably NOT from the flash drive.

I haven't done anything yet about cleaning his hard drive yet so it's undoubtably still full of crap. I'm assuming I need to follow the instructions I cited in post #32 before I actually install the new copy of Windows but haven't seen anyone confirm that. (It makes no sense to me to install the new copy of Windows 10 and *then* wipe the hard drive but then Microsoft does lots of things that make me raise my eyebrows in wonder so I'm not ruling it out.)

But mostly, I'm stuck trying to get his computer to boot from the flash drive, which seems to depend on getting that boot menu by pressing F12, which isn't working.

 

Apparently, Acer's first instruction in their Help for changing the boot order from the boot menu is,...

https://us.answers.acer.com/app/answ...ing-boot-order

 

Assuming F12 option is enabled as Bree mentioned, the easiest way to tell people (that I’ve found) is to start tapping F12 repeatedly as soon as you click restart and don’t stop until the boot menu is displayed.

 

Does he have a UEFI bios? If he does, open an admin command prompt and copy/paste this into the command window shutdown /r /fw /t 0 and press enter. He doesn't have to press any key. It will boot into BIOS where he can change the boot options. This only works with a UEFI bios.
