Windows 7 - Hard Drive space disappeared/lost

Hey guys
So I bought a windows 7 netbook a few months ago, and within the first couple of weeks it caught a big virus and almost nothing in the computer was working anymore. So I panicked and since this was the only computer I had, I downloaded a copy of linux, put it on a bootable USB and installed Linux over windows 7. Then eventually I made another bootable USB for windows 7, and I put it in and it only showed one hard disk where it was possible to install windows, and it was the C drive with only 97 gigs of memory (the computer actually has 250 gigs). So I installed windows over linux and now Im wondering where is the rest of my hard drive? Is there any way to get it back?

Thanks

before you install windows on the choosing your hard drive to install to, from there you can choose to create partitions, delete them, or format entire volumes.
Your best bet is to format the entire drive this way and do a fresh install.

So, are you saying that you used about 150GB for Linux(ie, 97 for Windows Partition & the rest 150 for Linux Partition)?
Technically, Hard Disk have Partitions/Partition Drives like C:, D:, E: etc based on your hardware configuration. C: is usually used to install Windows OS & any of the other Partition to install Linux OS in a Dual Boot Environment. If your Hard Disk is not properly partitioned, if you don't have other partition drives like D:, E:, etc, while installing Linux, you can manually configure to use a specific amount of Hard Disk space for Linux.

Did you make the OEM manufacturer's Recovery Disks?

No unfortunately make any repair disks. Rookie mistake. I'm doing a fresh install of windows as we speak and I'll choose the option that formats the entire drive. Hopefully this works I deperately need the remaining space.

Problem solved! I went tothe disk management tool, deleted the Linux drive and used that space to create a new NTFS drive! Thanks guys!!!
