You don't uninstall an operating system, you simply overwrite it. You should be able to go to the partition manager in Windows and tell it to delete the Ubuntu partition and expand the Windows partition to fill the empty space. Then you'll need to run the Windows recovery to rewrite the MBR to remove grub. You should make backups of your information before doing this.

Rewrite the MBR before deleting the Ubuntu partition. I don't know about 7, but in XP this is done from the Recovery Console on the install CD.

Do the company provide and install image? Do they have an IT department? Do you have any data on the hard drive that you need to keep? Which version of Windows? Do you have a "recovery CD", a full install CD, something else or nothing?
The advice above is good but if your company has an IT department you should give it to them, if not you should make sure you have a backup of any data you need before making any changes.

Which version of windows. If it's XP you can replace the old MBR using the fixmbr windows program from the windows rescue disk, or the installer disc in management mode. You can remove the Linux partitions in the Windows disk manager, or from your Ubuntu luve distro or the install disk. Some Linux distro's save a cooy of the original MBR in the /boot/ directory. You might want to copy it to a usb flash drive. Using the dd program from Linux, you can restore the first 446 bytes of this file to the MBR to restore the original. The last 64 bytes cintain the original partition table, but you may have reduced the Windows partition to leave room for Linux.

If you used wubi to install Ubuntu, then Linux is in a file inside windows. In this case, you only need to restore the MBR and delette this file. Also check if Wubi has an uninstall option. It may do both. Note: I've not used Wubi, so I don't know if this is the case.

If you use Vista or Windows 7, the drive management programwill allow you to resize partitions. After you resize a partition, windows may want to run a chkdisk program the next time you reboot.
