Well i am gonna take a stab here. I am not shore what your asking, do you know how to format in bios? Cause you said you chose to format local disk c, but then you ask how to format local disk c after that, so i am litlle confused on what you want to know.If you want to know how to format in bios and never done it before look at step 1, otherwise skip it.

1. First make shore you have ALL the original disks you need for your pc drivers ex: Motherboard,gfx card,windows cd and so on. Secondly make shore you backed up any files or folders you want to keep or re-add later after format,and store them on an external hdd or a cd or so on. Allso keep in mind if you format for the first time, note that you will loose ALL your data on the formatted drive and will have to reinstall everything that used that drive. So if you have say a drawing programe installed on "d",but the pics and work and so on are saved to "c" you will loose them and in some cases the programs or files wont work on "d" after formatting c, beacuse the "path" was in "c" and is now missing. Hope this makes sence, i am no expert.

Now to format. When you start the pc and the black screen or your motherboard logo comes on press "delete" key on the keyboard, this will take you into the bios, depending on the bios this will look different on each motherboard,but look for a tab calle boot or boot settings at the top of the pannel, go to it and search for boot prioraties(this could be a sepperate tab, or under boot settings) Now in boot prioraties choose your dvd/cd rom as first/primary boot device and after that press f10 to save and exit. ( If you strugle with this read the info in the bios next to each tab that you are on,it says in short what to do, or how to change it. If you still don't know i can upload a screenshot of it).

2. Now after you chose dvd/cd as your primary boot device, insert the windows os dick and reboot/reset the pc, when the black screen comes on and asks to press anykey to boot from disk press litterly anykey and the windows install will start, just follow all the onscreen instructions, and when you get to the part where you should choose where to install windows, click on the drive you want,then at the bottom click advanced then delete that partion(only "c", don't do anything to "d", or click on c to format and select the formatted partion "c" and click next, the installation will start.

Again,there is a good chance that files and programs on "d" won't start if they have a path to "c" or saved important files on "c" This is not a detailed way to do it, hope you understand what the risks are and understand from my weird and strange guidline how to format, if not i will upload step by step screen shots, or maybe some of the pro's can help better.

It's not wise to back up your data on another partition on the same HD, but if you have no other alternative (DVD, external, another computer on network, 25gb free storage on Skydrive with each Live ID) then boot the Win7 installer, choose Custom Install, then when it presents the drive selection screen, be sure to only choose the C: Windows 7 partition and not D: where your data is stored.

Follow these steps to get a perfect reinstall of Win7 and maintain it flawlessly: Reinstalling Windows 7
