I want to try to install Ubuntu 16.04 on a new laptop. This laptop has 64 GB eMMC storage which has pre-installed Windows 10. I don't want to change anything or break Windows installation. Because I don't own this laptop, I only borrow it for several days. I want to return it to the owner as original as I took it from him. But I want to install and test if this laptop compatible with linux or not.
So I put a 16 GB micro sd card to card slot of laptop, plug Ubuntu 16.04 installation USB pen-drive to USB slot and installed it. I followed these steps:
64 GB eMMC storage seen as emmcblk0 and it has 4 GPT partitions One of them is EFI partition.
16 GB sd card seen as emmcblk1 and I formatted it as one ext4 partition and emmcblk1p1 used for root partition during installation steps. I did not create any other EFI or swap partitions.
I choose to install bootloader to emmcblk1 (I tried with another installation to emmcblk1p1 and I get same result). I did not choose to install to emmcblk0 because I don't want to change anything 64 GB eMMC Windows disk.
When I try to boot system, I get 2 EFI entries called "ubuntu", and If I try to boot from one of them system drops to GRUB2 shell prompt. When I run ls command, I can only see (hd0,gpt1) (hd0,gpt2) (hd0,gpt3) (hd0,gpt4) entries. These are 64 GB eMMC drive's GPT partitions and I don't see emmcblk1 from GRUB2 shell.
What should I do from this point? What's wrong with this installation steps?
