Need help!Format netbook

i have an acer aspire one 751h which is running windows xp and edubuntu( it is ubuntu it just contains some extras for school). I don't like neither windows xp nor edubuntu.I want to acces recovery partiton(PQSERVICE) and change its file in order to istall windows7 or windows 8.I have an iso for windows 7 or windows 8. 1) how do i gain acces to PQSERVICE
2) how do i put files for windows 7 or windows 8 in this partition(should they be an iso or should i extract them?) and how do i erase the old ones? 3) after doing these how can i install windows 7 or 8(for example before i had been pressing alt+f10 so i can enter acer erecovery and install windows xp) ?
please help!
I tried to install windows and ubuntu directly through a usb but it failed. An error occured. that's why i'm trying to install them this way.
Disclaimer:My recovery partition contains windows xp and edubuntu and i don't want them

 

I did a clean install of Windows 7 on a similar machine, an Aspire One 532h. I burned the ISO file to a DVD and got an external DVD player that connects to the netbook via the USB port.. By doing a clean install, Windows 7 reformats the entire hard drive of all partitions.
