Will custom install reformat all my drives?


New Member
I have a Dell system with 2 internal hard drives. I have backed up all of my data to the second hard drive. When doing a clean (custom) install of Windows 7 will it reformat both drives or can I tell it which ones to format?

As Drew said

Only the drive you select for the OS install will be formatted

But you WILL get the choice to format the other drive(s), so be careful

Just look really close at which HD you select for format and install. There are many posts here where people picked the wrong one.
