You can't do a repair install unless you can boot into windows.
If you used the commands you specified, the data should be on the disk .
How do you mean you have to do a reinstall?
You will probably be able to reinstate the partition fully intact.
Download this - it's free and burns itself to cd
Paragon Backup & Recovery Free Edition - Free Download
Boot the cd , Select Normal Mode >Partition undelete
If that doesn't do it,
Try the partition recovery on the PW boot disc.
Free PW Bootable CD allows user to boot computer directly ...
Boot the cd, click the Disk at the top of PW main window to select it.
Click partition recovery in left pane. Do a quick scan of the HD .
Tick ALL partitions you want to keep, APPLY.
It is very likely they will recover the partition - a lot quicker and easier than a reinstall. They are both very useful boot discs to have .
