I have purchased my laptop last year in 2009; it came with Windows Vista Business. Now using Vista was horrible for me, I din not like Vista at all, now last month I brought new Windows 7 Ultimate. I did not want to remove my vista since it was full licence version so I thought of installing my Windows 7 multiboot so that I have both Vista and 7.

So I successfully installed my windows 7 ultimate. Now during installation there were couple of errors which made my installation not complete.

So I needed to remove my Windows 7 and reload it again and this is how I did it.

Format the Partition with Windows 7

For this on Windows Vista – right click on My Computer – Select Manage – Down you see Disk Management – Select that and go to Drive /partition which has your Windows 7 Operating System.

Right click on partition and select format – select quick format and select ok.

This process removes the Windows 7 Operating System from your system. Now you need to remove the multiboot selection entry from Boot screen. For that  click Start – Run – Type msconfig – a window open and you need to select the Boot tab – in that window you see an entry with Window 7.You need to delete that. That’s it.

I did this process and reloaded my Windows 7 and now its working fine.

Warning:

1. Formatting drive removes all the data. So if you have any data in the drive save it / back up it first.
2. Always have whole system backup before doing any critical changes in the machine, so that if anything bad happens you can restore back the whole system.
3. Be careful when editing the MSCONFIG boot tab; remove only the windows 7 one not the Windows Vista (or current OS).
4. If have doubt clear it before action so that you don do blunders.
