Scared to install windows 10

[PC Beginner2000]

So its pretty easy a friend of mine made a couple partitions
and installed ubuntu on one partition windows 7 32 bit and 2 system check softwares
with a program i dont know

and now when i boot up the pc i can choose which os i want to boot up
but now when i tried to install windows 10 64 it said that i need to choose a drive
and it shows me all the partitions so im scared to choose a partition
because it may screw up the hole dual booting software
and i dont know how to delete it
so please help me on sort of resetting the hole hard drive to remove the partitions
or anything else
to just install windows 10
i dont mind if my files get lost

Please dont mind my bad english
Also if the category is bad please move this thread

Did you buy win 10 or just have a installer?

Either way, just follow this and it will show you how to delete the old partitions that have the dual boot on them and just put win 10 on

The only difference is, if you have bought win 10, you put its code in, if you just have the instller, ou will need your win 7 serial number to register win 10

Why would you buy win10 when upgrade from legit win7 is for free?
Just upgrade your windows7 to Windows10. It would upgrade to win10 32bit version though.

Are you sure you need 64bit windows? Do you have more than 4GB of ram?

First off you cannot upgrade a 32 bit system to a 64 bit system, so skynetrising is right about doing the free upgrade. If you do want the win 10 64 bit OS, that requires a clean install. When you try to install and it shows the 2 partitions the discription should let you see which partition has what on it. When you install the new OS it will automatically rewrite the MBR so you should not have a problem in that regard.
