You will need your Win7 disk or borrow one.
Then follow this guide.

You will need the WIn7 installation disk or System Repair Disk.

Boot disk then Mark Win7 Partiion Active.

Then run Startup Repair - Run 3 Separate Times until Win7 starts and is labeled System Active in Disk Mgmt.

Then post back a screenshot of Disk Management - Post a Screen Capture Image so we can help you delete the XP partition and recover its space as you desire.

It is never correct to delete an OS by its files, only by its partition.

Reboot and tap the one-time BIOS Boot menu key to get a menu to boot the disk. Follow the steps I gave above.

If necessary because the Boot Menu key won't access, you can enter BIOS setup to set the CD/DVD drive to boot first, save settings and reboot, Press Any Key to Boot Disk: How to Boot A Computer from CD or DVD - YouTube
