I installed ubuntu server on my windows 7 computer and can't reboot windows 7. I want know if I accidently formatted my hard drive or if I accidently replaced my OS. How do I download ubuntu from the ubuntu server terminal?

Are these two separate questions? How does, "How do I download ubuntu from the ubuntu server terminal?" relate to the rest of your question? Also, please run df -h; mount; sudo fdisk -l; sudo parted -l on the Ubuntu Server system and edit your question to include the text it tells you...*if* you are still booted into the Ubuntu Server system. Then shut down the Ubuntu server system with sudo shutdown -P now. (If you aren't still booted into it, don't boot back into it--instead, use a live CD to gather this information. This is in case you did overwrite your Windows system and documents.) –  Eliah Kagan Nov 16 '11 at 0:24
    
Please also see the considerations in the Data Recovery documentation, if it is at all possible that there were important documents in your Windows installation that were not backed up when you installed Ubuntu Server. (Whether or not your Windows system has been destroyed can be determined given the output of the command I provided in my previous comment, but if there's any possibility of loss of important data, you shouldn't use the installed Ubuntu Server system more than a few seconds longer than necessary, as that could cause more loss.) –  Eliah Kagan Nov 16 '11 at 0:27
    
I want to download ubuntu to check if my files are still there because I don't have my windows 7 disc to redownload onto my computer. –  Janbro Nov 16 '11 at 0:28
    
Are you still booted into your Ubuntu Server system? If so, please run df -h; mount; sudo fdisk -l; sudo parted -l and report the results (then shut down as explained above). If you had any important documents in Windows, then it's critically important that you do not create files in your Ubuntu Server system, as doing so is likely to overwrite the data and make those documents impossible to recover. Therefore, unless you have no important documents in the Windows system that are not backed up, you should not download an Ubuntu live CD .iso image in the installed Ubuntu Server system. –  Eliah Kagan Nov 16 '11 at 0:33

The text from the command line that you have included does not show anything that looks like a Windows partition, so it is highly likely that you have installed Ubuntu Server to the entire disk, destroying your Windows system. While it is extremely unlikely that you could recover your Windows system, it may be possible for you to recover some important documents that it contained. You can follow these instructions for doing so, starting with shutting down the system immediately (sudo shutdown -P now) if you have not done so already.

You'll need a live CD/DVD or live USB flash drive for this, but you should not attempt to create it on the current Ubuntu system, because (1) the longer you run the Ubuntu Server system, even if you are not doing much with it, the greater the risk of irreversible data loss from the contents of the old Windows partition, and (2) if you were to download a large file (like the Ubuntu desktop CD .iso image) on the system, that would be very likely to overwrite data that had belonged to files that were stored on the Windows system, very possibly including the important documents you wish to recover.

If those instructions don't enable you to recover your lost files, then you'll have to decide whether or not it's worth it to hire a data recovery specialist, which could cost thousands of dollars. You should probably not hire someone who is not a specialist for this purpose if these methods are not successful, because only a specialist is likely to be able to recover data not recoverable by those methods.

As for getting Windows back, you will need to reinstall it to achieve this. If your computer came with Windows but did not come with installation media (like a CD, DVD, or USB flash drive) then it is usually possible to order a Windows installation CD/DVD from your computer's manufacturer at relatively low cost (certainly much less than it would cost to buy another copy of Windows providing a new and separate license).
