[SOLVED] Some questions with dual booting

[Alex]

I recently bought a second hand HP laptop, which has Win 7 installed and running OK. I would like to retain Win 7 as I need it for a few non-Linux programs, on the other hand I love using LL for most tasks. So, I am considering having a dual boot machine, hence some questions:

1. Is it recommended that the dual boot be done using easy BCD? As shown in this video:

2. Is it a good idea to retain all banking/payments/ transfers in LL - because it is more secure?

3. How much HD space should I allow for the LL portion?

4. If a virus/malaware happens to infect the Win 7 partition is it likely to contaminate the LL partition?

5. Are there any other problems that a newbie like me should watch out for?

Thanks for your help
