Need help to setup windows 10

style master · 16 Jul 2017

Hi, I have an Acer Aspire V3 (originally bought with Win 8).
Few weeks ago I updated it to Windows 10 and now Windows 10 is working fine (even if slowly).
I want to format my hard drive and setup again Windows 10 (the classic setup, not just an update... so yes, I will loose all of my files).
I've downloaded the MediaCreationTool, and already setup a bootable usb with Win10.
Now comes the questions:
1) Should I change the BOOT mode from UEFI to Legacy in order to setup Windows 10? (right now is UEFI)
2) In the attachment you can see the partitions that I have. Can someone guide me to the formatting? The partitions are too much for my knowledge and I don't want to make stupid mistakes.
I'm a noob so sorry for this post.
Thank you

13. If Installing Windows 10 with UEFI
A) Delete all partitions/volumes on the Drive # (ex: Drive 0) that you want to install Windows 10 with UEFI on until that Drive # shows as unallocated space. (see screenshot below)

Careful. If any partitions contain valuable data, OP should back up data first.

There is no need to turn off Secure Boot, there are rare instances where it needs to be turned off, but for most, just leave it on. Windows 10 install media has the files needed for Secure Boot. I don't ever turn it off when doing a UEFI install.
