Vista - Reinstall windowvista Homebasic using recoverydisc

Hello anybody helpme please,

This is my first time for joinning and asking about my

computer problem.Last 4 months ago,I bought a new laptop computer

HP-Compact Presario V6000(Window Vista home basic version) first time.

But the shop didn't give me a installing disc for my

computer.the shopkeeper said that I can make a recovery disc using

with recovery manager program from my computer.And made it.

One month later, I got a copy window vista Ultimate disc

from my friend and installed it for a month (actually I didn't

understand that's need to activiate during 1 month before expired

that kind of version).After that I tried to reinstalled my origenal

version of vista homebasic using with my recovery disc.But there was

showing that "your recovery disc is unable to install and error

message" behind blue screem.And I asked to one of my friend and he

tried to reinstall again my vista home basic.Maybe he called to

costumer service and fixed it my computer become to genuine.But my

friend is not here anymore.Please try to read and help me as much as you
can.take your
time.

Ok.the question is

1.How do i reinstall my window homebasic using my recovery disc?

2.There's showing a file(bootsect.bak) in drive C,what does it mean?

3.Do I need to Reactivate again if I reinstall ?

3.How different between genuious and none?

4.How can get window areo and media center for my computer (any free

version (or similar)on internet)?
5.How can use sonyericsson K750i software with visita(not compatiable with
vista XP only)


-That is..Thank you very much ,waiting for your any suggestion.
