I have some problems setting up a dual boot between Win10 and Ubuntu20.04. To be specific, it seems the bootloader grub doesn't find my second hard drive. Note: I've added some pictures at the bottom.
My setup:
- Microsoft Surface Pro (2017) with internal SSD (256GB)
- SanDisk - High Endurance MicroSD-Card (128GB)
My Plan: Set up a dual boot with Win10 on the internal SSD and Ubuntu on the added MicroSD-Card.
What I did: Note: I've tried to install Ubuntu serveral times now and always ended up with the same grub-problem.
- I used "rufus" to create a bootable USB-Stick. I made sure that UEFI is enabled. (pic. 1)
- I disabled "fast-boot" in Win10 and "Secure-boot" in UEFI
- I booted with the USB-Stick, went into live-mode and installed Ubuntu. On my...
- ...fist try I chose "Install Ubuntu alongside Win10".
- ...second try I chose "something different" and partitioned the drive myself (like in the answer on this question).
- ...third try (current state) I chose "erase disk". Every time the installation went well, but not once I could boot normally.
My Problem: When I restart after installation I always end up in the "grub bash like" terminal (pic. 2). I read in a tutorial that I have to tell grub where my "root" is, but when i type "ls", the second Hard drive (MicroSD-Card) doesn't even show up. When I type "exit", Win10 boots normally. When I reboot, enter UEFI and tell it to boot into Ubuntu directly, it works (pic. 3&4). But on every "normal" boot, it sends me to the grub terminal.
What I've tried:
- I've tried different installation methods (no difference)
- I've tried using the Boot-Repair tool. No effect.
I've had the same problem a year ago with my main Desktop-PC (I also used a separate SSD for Linux) and had the exact same Problem. Last time I surrendered. This time I want to find a solution.
Pictures:
- Rufus - Bootable USB-Stick
- Grub2 - Bash like terminal
- UEFI - Boot-configuration
- Grub2 - Boot-menue
Edit 1: I tried boot-repair again, this time in advanced mode. These were the settings (those were default)
The returned Summaries:
Here is a Picture of the partitions in GParted
New Problem: Now I can't even boot manually into Ubuntu via UEFI anymore. The entry is still there but if i chose "boot with ubuntu" the screen goes dark for 2 sec. and I end up in UEFI again.
Note: I had to delete some pictures because i can only incluse 8 Links.
