My laptop is divided into three drives: C, D and E. Windows was installed in C and Ubuntu was in D. I format C and E by deleting and to NTFS using gparted. But when I restart, it tells me a "missing Operating System". How can I tell the BIOS to boot from D? Or is there anything I can do? I installed several big software in the Ubuntu system, so I don't want to reboot from a USB and to lose the saved data. Thanks!

Thanks for all your answers. My question is solved. I just reboot from a USB and re-install the system and software.

  • It sounds like you were using WUBI, in which case, you're going to have to reinstall the proper way. – psusi May 14 '13 at 15:25

Try Boot-Repair.

Boot-Repair is a simple tool to repair frequent boot issues you may encounter in Ubuntu like when you can't boot Ubuntu after installing Windows or another Linux distribution, or when you can't boot Windows after installing Ubuntu, or when GRUB is not displayed anymore, some upgrade breaks GRUB, etc.

To use boot repair, you can download the ISO, and brun it to a CD. Once the CD is done, go ahead and boot from it, and just follow the directions.

It sounds to me like your bootloader was installed on C: and in formatting that, you lost your bootloader.

See here: How do I reinstall bootloader?

I would suggest trying to repair GRUB. The easiest way to do that is probably to use Boot Repair application. Just do these on Live-CD or Live-USB session. You do not need to burn on CD anything if You have disc or pen-drive with any version of Ubuntu or - I think - even any Debian distribution installer. Anyway launch Terminal and paste following commands there to install Grub Repair.

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install boot-repair

After installation, launch Boot Repair using Bash and try default repair. Reboot. If the problem still occurs You can try Boot Repair advanced options.
