Installing new windows 7 64 bit

[rudrashukla68]

I have two os installed on my HDD, Ubuntu and win 7 32 bit, I want to remove Ubuntu and install win 7 64 bit, I searched in msconfig boot, there was no Ubuntu in it , only win 7 32 bit, so I just want to install win 7 64 bit, so what steps should I do to remove these both systems and get my desired one without losing any data on other drives.

Disconnect the other drives. Format your OS drive and start from scratch, once happy everything is running ok reconnect your data drives.

You really should have your important data backed up.
