Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
To get started, I need to know what type of computer you are using, a Windows XP, Vista, Windows 7, Windows 8, Windows 10 or a Mac.If its a Mac, please check the OSX version as follows, Click the apple sign at the top left of your screen, then click about this mac. And then where it says version, send that to me as a reply.
Thank you.. Since this was just working before you downloaded the driver.. Lets turn back the clock.. The system restore below will not erase your Pictures, programs, or files.. And if we dont like the outcome.. We can undo it.
we need to do this special trick to force a repair screen.Start the computer, then immediately press and hold power to shut it down.repeat that 4 times, and then the last time when you start the computer do not press and hold power.It should go to a blue screen menu. On the blue screen menu, Choose troubleshooting, advanced, and then choose system restore.Once system restore loads, choose a restore point that was one day before this problem started and then carry out the system restore.That should fix the issue, but if you get stuck or this doesnt work then please send a detailed reply and I will assist you further as needed.
And if this does work please remember to return here, click and submit a 5 star rating to show I was able to help you solve the problem!

You will have to repeat the first steps..
And to clarify, when you power the machine on and it shows power, you must then Press and hold power, the physical power button until it drops power. Dont just tap the power button.. press and hold it.
Repeat that 4 times and on the fourth time when you press power, we should get a new screen
Is this a desktop, or a laptop?
What model of laptop is it? Name brand and model if you could that way I know precisely what we are working with.
For it to say unmountable boot volume..
Did you go into the Bios settings menu via the f1 or f2 keys and change or tinker with your boot order, or boot modes?
The computer cannot read an ISO file directly..
It has to be burnt to a USB or a DVD using a special program.. You cant just copy the iso file onto the disk and expect it to work.
With that being said, Lets try this.. Shut down your gateway, start it and immediately tap F1.
Then, we need to load defaults, save and exit.
Once done, let the computer try to start and tell me what happens next.
Lets try delete to enter setup.
Here is where we need to load defaults and exit.. In the bios screen.
Also, It could be your BCD or boot file is borked.. You mentioned you created a Windows ISO disk.. So I take it you have a second windows PC nearby you and I could use to make a proper boot disk?
I definitely do not think its your motherboard.. What we need to do here is create a proper repair DVD or USB.
The iso file you had, was it for your same exact version of windows 10?
If so, we need this free program called rufus.. This will make a bootable USB drive we can reinstall or repair windows with.. ( using the same iso file )
Or, if you need or want to stick with a DVD.. You need this specific program to burn that iso image to the disk properly
From this page, use mirror 7 for the download. With that being said..
If you let me know when you will be with your friend again or if you talk to your friend and can forward me t heir contact details.. i can work with them to insure that we have the cd or USB formatted correctly.
And then you and I can continue with the repair or reinstall steps using the correctly formatted cd or usb..
And speaking of your laptop.. If you have a spare usb drive at least 4 gigabytes in size.. We can use your laptop to make a bootable usb, exactly the same as a bootable cd.. So if you have a working machine and a USB thumbdrive, thats an option you and I can proceed with now.
All right.. if needed, I can connect and do this for you..
First, we need a windows 10 iso.. I assume you have an iso image on the CD?
Can you insert the cd into your current computer.. Then, explore the file on the cd and tell me if it shows a windows image or .iso file?
If so, whats the exact name of the iso file on that cd?
No worries.. The media creation tool is microsofts version of the tool thats supposed to Make the cd...
Your friend was moving in the right direction, but taking steps like this are foreign to most people and mistakes will happen..
So heres what we need to do.
Download the tool on this page to your computer.. Then, open and run the tool and tell it to make a USB.
if you get stuck at any point, let me know! Consider the download and creation takes about 1 hour with reasonably fast internet..
Lets just focus on the download first.
Then next.. If you go to your my computer screen..Do you see the drive listed nearby your C drive?
My apologies for the delay.. Its gotten quite a bit late my time..
Would you mind greatly if we continued tomorrow? Ill be working throughout the weekend.
I think that you and I are capable of performing any steps they would perform at a shop.
If you did not have access to a second computer, that would not be the case.. but it is the case that you have a second computer and a USB drive. So we should be able to do nearly anything a shop can do.
Ill look forward to working with you Monday.
Hello again.. I ended my shift a bit early yesterday, and Im starting a bit early today.
When you can, send a reply and let me know when you might want to try and continue, thank you.
