On a computer running windows 7, I created a new partition and installed Ubuntu on the empty partition. Then in windows, I deleted the partition that ubuntu was installed on. After restarting my computer, I get an error:

error: no such partition

It sounds like when ubuntu was installed, it wrote over the windows bootloader, and I deleted the partition that Ubuntu's was on.

It sounds like I can reinstall the windows bootloader using a windows 7 disk, but will this erase the data that was on the windows partition? If it does, is there any way to recover that data?

Your best bet it to insert the Windows 7 installation disk and boot from it, then click "Startup Repair". That usually works 99% of the time. (You won't lose any data or anything like that)

Yes this should work. If you don't have a windows 7 disk there are a couple of stripped startup repair cd/dvds floating about that don't actually contain the entire OS so they are freely distributed. – RobotHumans May 12 '11 at 19:31

Insert your Windows 7 CD and choose Command Prompt or Recovery Console - I can't remember which one.

At the command prompt, enter the following:

bootrec.exe /FixMbr

That should then restore your Master Boot Record, and allow the computer to boot into Windows.

Super Grub Disk can fix MBRs. It's my choice for these scenarios mainly because I don't know DOS commands but I do know *nix ones.

It's also free software.
