Uninstall ubuntu, install windows 7

Hi, i have a problem, right now I have ubuntu 10.4 on my laptop but I want to install windows 7, the problem is that, the auto run disk (w7) doesnt run, i tried to search overt the internet, and have no lucky, it says that i have to boot it on BIOS , but i cant acces it. i tried to press, F2, F12, esc, DEL and still do nothing.

sony, VGN-NR220E
It use to have w.vista
pentium dual core

Do you have something that can helpme??

no i have not, but this disk is brand new i think it supposed to boot in another computer, is the home premium version

just installed on a dell. f12 to choose boot order and then scroll down to CD

I did i it 2 min. ago,and nothing >(

Dude press ESC. Works on my Compaq.

Sony uses the F2 key. Tap it repeatedly every second as the computer boots up. Enter BIOS setup and set DVD drive to boot first like this: http://pcsupport.about.com/od/tipstr.../bootcddvd.htm

Wow, how many people here replied without eading his whole post? he said has tried all that and it doesnt work, telling him another button wont help him! im extremely pissed off at the fact that the only people who replied are people who didnt even read his post as I am having the same problem as he had.

All Linux code must be deleted using the CLEAN ALL command.As you have had linux on the HD you need do a Clean all & full format.

Do a full clean & full format in command prompt.
1) Boot DVD & Press Shift+F10 (for command prompt)
DISKPART : At PC Startup
2) Boot DVD, & Command Prompt at Startup

Type in command line
DISKPART
LIST DISK
SELECT DISK # (win HD)
CLEAN ALL
CREATE PARTITION PRIMARY
SELECT PARTITION 1
