I'm trying to install Ubuntu on my external HDD. For some unknown reason, when I install the bootloader on the external HDD, it doesn't boot, showing only a blinking cursor with nothing happening. I was wondering if I install the bootloader on my internal hard disk but on a drive different from my Windows drive, will grub fail if I do not have the external HDD connected to my PC?

You should install GRUB to your boot partition (if you are booting Windows successfully). Obviously, your BIOS settings is configured to boot from that drive, thus it posses bootable flag partition. GRUB should not fail booting Windows if your external drive is not present, but logically it will be unable to boot ubuntu if external drive is not connected. If you connect external drive, it should be able to boot into both Windows and Ubuntu.
