I have 3 Hard drives:
OS (C

- 11.8GB Free of 99.1GB
RECOVERY (D

6.05GB Free of 9.99GB
LOCAL DISK (F

413GB Free of 465GB
My C drive is obviously my main drive, the recovery is..i dont know it was there when i got the laptop and the F Driver is an external. (Maxtor)
What i want to know can i install the Windows 7 on the External Hard Drive (F) and when i boot up my PC i can select between the 2.
But in the F Drive is like games and other stuff, and theres about 10 folders in there.
How would i go about installing Windows 7 and if i can and install it on my external will that effect anything to do with my cdrive?
If i do download it i will be downloading the 64bit version as ive looked to see and my laptop is capable.
what type and size of disk will i need?
Thankyou
