I'll usually delete the partitions since formatting can trip up a Windows install. I start with a blank drive.
But and this is important, why not use the factory recovery system because most folk can't find drivers and apps for their PCs today?
I am suspicious that I have a key logger installed on my computer as my insta account got hacked 2 times, so in my computer I have 3 partitions of hardisk. I have 3 questions related to it:-
note:- I have a live usb with win8.1 in it bootable usb to install win 8.1
1.) now if I install iwn 8.1 in another partition and then format the main local disk with the original or stock OS will the key logger be removed and will I be able to boot my computer?
2.) If I format all three partitions I mean first format the non OS partitions and then format the official partition will I be able to install win8.1 with the bootable usb I have on the partition and will I be able to run my computer or would it be a piece of crap?
3.)IF not any of these will work what do you suggest I do ?
