Format Hard Drive...

Hey guys, I have a HP Pavilion dv7 laptop. Recently, my computer has encountered some sort of hard drive issue. It started with the constant windows repair loop (yes, I tried all the solutions to fix this) and we found out it was an issue with my C drive. Anyways, I can't boot my computer, nor can I access safe mode. It tells me I need a windows repair disk.

I enter one that I created with my mother's computer and it runs. But, it tells me that my computer is missing drivers.

Anyhow, I don't have any sort of repair disk because the computer I got was refurbished from Microcenter and didn't come with any sort of disk. I've the computer for just over a year now and have had no issues with it until Sunday.

Is there a way that I can format my C drive without actually being able to boot windows? I can access the C drive from the repair disk and it tells me "you must format this disk to use it," I press "format" and it tells me that this disk cannot be formated because it may be disconnected or in read only mode. I went ahead and reconnected the wires from the hard drive to the C drive to see if that was the issue, same problem.

Anyways, how can I format my C drive?

This is extremely helpful, thank you VERY MUCH. The issue.. How do I find my Windows activation key if I cannot start my computer?

Thanks for all the help guys, probably seems like I'm a newbie. XD Anyways, it's all fixed now. I didn't even have to format my C: drive, just had to repair windows. Apparently it had suffered a "Fatal error" during an update.
