I have a problem with my hard disk so I removed it, stripped off an external hard disk and inserted it into my laptop. Now i want to install windows 7 on this disk but the installation is not showing me format and disk partition option. I want to know if my hard disk will be formatted if I go on with the installation?

When you choose custom installation at the time of installing instructions of Windows then tgere is an option Drive options which will show you advance option for a selected partition. – avirk Jun 12 '13 at 0:31
@avirk i know but all the options are greyed out – whatever Jun 12 '13 at 0:45
The options shouldn't be greyed-out. See How to Do a Clean Installation with Windows 7. – martineau Jun 12 '13 at 1:03
If all else fails you can always use GParted. – Karan Jun 12 '13 at 5:10

If you have a windows XP operating system disc with you, then try to do partition by using it and then insert windows 7 disc and go on with the installation.

Can you explain why the XP disc would work but the Win7 one wouldn't? – Karan Jun 12 '13 at 5:09
because i have noticed that there is a possibility of changing basic disk to dynamic when windows 7 disk is used. this happens when we create more than 3 primary partitions. so to avoid such issues windows xp disk is better. – Renju Chandran chingath Jun 14 '13 at 11:22
