Hi guys, I am completely new to Ubuntu. I am having a problem booting Ubuntu 18.04 from my external hard drive, and I would really appreciate your help if possible. I have already checked a lot of threads similar to my problem but none of these worked for me - or at least I was not able to make them work - so this is why I decided to write my own thread.
So, here is my situation:
My laptop is Hp EliteBook 840 G1 and has Windows 7 Professional Edition 64-bit on it. In the beginning, I tried to install Ubuntu on my laptop's HDD, but because the disk is dynamic would not let me install Ubuntu on it.
So I decided to go for installing Ubuntu on my Seagate Portable 2TB External Hard Drive Portable HDD. I formatted the disk to NTFS (it would not let me shrink it while it was exFAT), made a 40 GB unallocated space, and then began the installation of Ubuntu. I gave 8 GB to swap space, 32 GB to ext4 and the installation seemed to be successful. After the installation was completed, it asked me to restart my computer. So I did and this was the last time I saw my installed Ubuntu.
While my laptop boots, I go to Boot Device Options and select the external hard drive, but it just sends me back to the HP screen which is the first thing that appears when my laptop boots. If I don't to anything, it just boots Windows of course. (Also if I boot the USB I used to install Ubuntu, I can get to the "Try Ubuntu" screen).
I changed the BIOS boot order and put the external hard drive first, but this just puts my laptop in a loop appearing the initial HP screen again and again.
I was now trying the boot repair, but this message appeared:
"SFS detected.
You may want to retry after converting Windows dynamic partitioning (SFS partitions) to a basic disk.
This can be performed via tools such as TestDisk or EASEUS-Partition-Master / MiniTool-Partition-Wizard.
Do you want to continue?"
So, basically I am stuck with not knowing if it would be safe to proceed with this. I have read some other articles but didn't get a clear answer.
I really feel that my problem is not that complicated and that I am probably missing something, but I am completely new to Ubuntu, so I would really appreciate your help.
Please let me know what other additional information you need in order to help me, and I will provide it here.
Thank you very much in advance!
