I recently installed Ubuntu 14.04 on my laptop. I already had a single Windows 7 partition and two linux partitions. The problem is that Ubuntu overwrote the grub bootloader, and now there is no option to boot to my encrypted debian install
Here is my disk layout
- Windows partition /dev/sda1
- Extended partition /dev/sda4
- Ubuntu / and /boot on /dev/sda5
- /boot for Debian (ext3) /dev/sda2
- LUKS volume
- ROOT-FS / for Debian
- SWAP-FS swap for Debian
I want to be able to boot to the encrypted debian install, Ubuntu and Windows from the grub boot screen. How can I do that? I don't want to use paid or closed-source software.
Bonus: move the debian /boot and grub to a usb stick and boot from that.
