I had installed ubuntu (twice actually) onto the same drive. I wanted to 'try again' since one of them didn't install correctly and the other installed differently, but it worked. I was getting frustrated with the grub menu because it was really sloppy (There were two windows loaders-one with the windows boot loader to go into Ubuntu-2 different versions of ubuntu-from the first install for some reason- the memtest, etc.).

In my attempts at getting rid Ubuntu to do a fresh installation, I went ahead and deleted the partions that weren't the swap or main via Windows 7. As I said, I am a noob. Now, even though I though I completely got rid of Ubuntu, which includes the grub menu, when I boot my PC I am brought directly to the Grub Rescue. And from what I've found from other forums, the grub rescue isn't even completely functional for me (it doesn't recognize any commands that it should support besides 'ls.' It also returns and 'unkown filesystem' for any partition I try to view or boot.)

Is there any way that I can boot straight into Windows? I fear I may have gone about deleting those partitions in the wrong way. If so, what are my options?

Along with this, I don't have access to a Windows CD, but can get one for Ubuntu if necessary. I did try to boot from a flash drive with the Ubuntu iso though, and that brought me to the grub rescue prompt as well. –  Jaden Rasmussen Dec 13 '12 at 20:40

I don't if its possible to get rid of grub entirely, and boot just windows (without simply reinstalling windows), but you can fix your grub - just get an ubuntu live cd (or USB) and use Boot-Repair - the 2nd option listed at https://help.ubuntu.com/community/Boot-Repair

Assuming your partitions are still in order, you can fix the MBR in Windows Recovery and it will boot back into Windows.

If you do have an Ubuntu partition, it won't be wiped so you might need to do additional clean up no your partitions afterwards.

Assuming you are using Windows 7 (this should also work on Vista and Windows 8):

  1. Put the Windows 7 installation/Upgrade disc in the disc drive, and then start the computer (set to boot from CD in BIOS).

  2. Press a key when you are prompted.

  3. Select a language, a time, a currency, a keyboard or an input method, and then click Next.

  4. Click Repair your computer.

  5. Click the operating system that you want to repair (Windows 7 in this case), and then click Next.

  6. In the System Recovery Options dialog box, click Command Prompt.

  7. Once in the command prompt, type exactly Bootrec.exe /FixMbr and then press ENTER. You will see "operation completed successfully." (Doesn't even take a second. Don't be alarmed )

  8. Reboot and set BIOS to boot from the HDD again.

GRUB will be overwritten in step 7 and Windows bootloader will once again take control of loading your OS(s).

Then load your bootable pen drive or CD so,your your problem will be solved.

All the best!
