I want to setup my Dell Latitude laptop with an Ubuntu 10.10 in addition to the already existing Windows 7 installation. Windows is installed on the internal hard drive, which has a Bitlocker encryption. Ubuntu is supposed to run off a second hard drive, which I inserted in the laptop's modular bay through an adapter. Therefore, it is occasionally swapped with an optical drive and is not present every time. The setup is:
/dev/sda1 /dev/sda2 ntfs Windows 7 (encrypted) /dev/sdb1 swap /dev/sdb2 ext4 for Ubuntu /dev/sdb3 (additional data partition)
My first attempt was to install Ubuntu regularly to the second hard drive. This overwrote the Windows 7 MBR. The catch is: Bitlocker now refuses to boot (maybe because the MBR was changed?), and if I remove the second hard drive, grub enters rescue mode.
I tried restoring grub with
sudo grub-install --root-directory=/mountpath/of/sdb1 /dev/sdb
and also reinstalling Ubuntu and putting the grub in /dev/sdb, but advising the BIOS to boot from the modular bay hard drive, it won't find GRUB.
I further tried to add a GRUB2 boot entry via EasyBCD, but it won't find it, either (Says "No ang0")
Any ideas how to implement such a setup?
