Windows 10: No external hdd or touchscreen after clean windows install

I re-installed win10 on my ASUS Q302LA laptop after completely wiping the c: drive using Ubuntu. I installed Ubuntu in order to delete the "Old windows" folder, which apparently can only be done from windows if you have god or "trusted user" status, whatever the hell that is. After installing over Ubuntu using win10 from an iso optical disk, the usb ports and device manager no longer register my seagate external hdd. Now this is scary because the seagate is a "backup" drive and now it's useless. It's still good and works fine with my hp elite so nothing's lost, but the idea that were I not to have a second computer my data would be unaccessible by the very products supposedly designed to keep it safe. The touchscreen feature is also non-functional. I'm not sure whether this is a win10 problem or an ASUS driver problem specific to this computer.

Touch Screen on Windows 10 Not Working

You said there "probably" would be a yellow tag next to the device. However there is no yellow tag next to anything in my device manager. I just did a clean install of win 10 and now the touchscreen doesn't work on my asus q302la. Also, the computer
will not recognize the Seagate external hdd.

 

Windows defender No longer working

1. Was AVG installed when you upgraded to Win10?

2. When (exact date) did you replace/upgrade the HDD & then do a clean install of Win10?

3. Did you back up any data to an external source before you replaced/upgraded the HDD and then restore to the data to the HDD after doing the clean install of Win10?

 

I disabled "legacy usb" and "xchi pre-boot mode" in the bios set-up and it works now.
