I'm having trouble booting ubuntu from an external hhd. First off I guess specs. Computer is lenovo t530 thinkpad. External hhd is seagate expansion desk (3tb). In the t530 there are 2 drives. 1 500gb hhd and 1 16gb ssd. Windows 7 installed on 500gb drive. Lenovo recovery stuff is on the ssd.
Here's what I've done: created Bootable usb memory stick. I can boot the live usb/cd from that and mess with ubuntu live. I've then ran the installer from the desk top of ubuntu live. Created 2 partitions on ext. Drive. Both ext4. Mounted and formatted one (roughly 11gb) for the Linux install and one roughly 9gb ( for swap. And changed it to swap). Now here I've tried 2 things. First I tried to install bootloader on the partition that I installed linux on. Later to find out that's not correct. So then I just installed bootloader on the actual device. Gparted lists drives and partitions as follows : sda (windows drive) sdb (external drive with partitions sdb, sdb1,sdb2,sdb3.) And sdc (ssd). So I installed bootloader on sdb. Everything seems to install fine. When I go into bios I can see the ext drive in boot priority and can change priority. But when ext drive is first it just boots to black screen with a blinking cursor. Windows still boots fine if it's first. And the memory's tick boots fine if it's first. Guess I'll stop there and hope for some advice. Thanks.
