Formatted my linux SSD some days ago. Somehow that messed Windows up from booting. If I went into the bios, and selected the Windows Boot Manager, it would just go back to the bios. If you boot the DVD in UEFI mode, Windows 7 can repair it for you. Just click next on the first screen, then click repair, it’ll search for Windows, and you’ll get a popup asking if you want it to repair your startup problems.
To boot the Windows 7 DVD in UEFI mode, put the disk in, reboot, and go into your bios. Most likely your bios is different then mine, so you’ll have to look around.
