I have Window 7 installed on my laptop and I can install Linux (Ubuntu). I just wanted to install it with the following conditions:
At the time of booting I get option for both OS, but if I delete Linux OS it should not affect the booting process of Windows. May be it automatically gain Windows bootloader or if its Grub, its OK.
I am not aware of what is "sda" at the time of installation. Can I create "sdb" without destroying Windows partitions and install Linux in this "sdb"? I got free space in my system.
