So I'm a big fat idiot.

I installed Ubuntu 11.04 on my school's laptop, and here's come the time that I have to turn it back in. I wrote GRUB to the Master Boot Record, thinking it wasn't going to be permanent.

So, fast forward to yesterday. I decided to hell with this, and popped in my Windows 7 CD, deleted the whole partition, formatted to NTFS, and installed Windows 7 on it. I'm surfing the web and my computer overheats [totally typical]

I boot up, and get this:

Try (hd0,0): FAT32: No GRLDR Try (hd0,1): invalid or null Try (hd0,2): invalid or null Try (hd0,3): invalid or null Try (hd1,0): NTFS5: No grldr Try (hd1,1): invalid or null Try (hd1,2): invalid or null Try (hd1,3): invalid or null

Cannot find GRLDR. Press space bar to hold the screen, any other key to boot previous MBR... Timeout: 5

The timeout part just counts down to 0 from 5.

I need to turn in this thing before tomorrow, please please please can someone help me out?
