Dell Chromebook 13 with Windows 10 and Ubuntu 18.10 on dual boot, using MrChromebox UEFI Firmware (4.9)
What happened
I wanted to install Ubuntu on an external usb drive. I took two drives, installed the live version of ubuntu 18.10 on the first, booted into it, and then used the installer to install ubuntu on the second usb.
When the installation finished, I removed the drive and rebooted – just to find out that the laptop boots into GRUB 2.2 (with “Minimal BASH-like editing supported”) rather than into Ubuntu.
I can still boot into Windows by selecting it in the boot manager but if I do nothing the computer goes into GRUB.
What I did
testdisk's first analysis could not find any partition, so I did the deeper search. Here is the result
Code: Select all

The harddisk (256 GB / 238 GiB) seems too small! (< 12 TB / 11 TiB)
Check the harddisk size: HD jumpers settings, BIOS detection...
The following partitions can't be recovered:

Should I just try to change that partition characteristics from `D=deleted` to `P=primary`?
Are there any other partitions I should recover? When I try to visualize file in many of them (like the preceding one) I only get this message: `Can't open filesystem. Filesystem seems damaged.`
Or should I just give up and reinstall everything or is there still some hope?
