Wed 20 Nov 2019 10:23:07 PM UTC, original submission:  

First, I have some strategic questions:

 1. The Ubuntu installers automatically invoke grub-install in UEFI mode on UEFI hardware, even if I want to install grub2 on an external SSD. Can I avoid this, i.e. use the legacy BIOS/MBR-mode grub2 booting? In my case, Ubuntu 2019.04 installed itself on an external SSD in MBR mode on an UEFI laptop and pointed the EFI partition to Windows’ GPT EFI partition (/dev/sdb1) so that I can only boot Ubuntu on that same laptop or on PCs with the same Windows GPT EFI partition.
 2. Can grub2 cope flawlessly with MBR partition tables that were converted by gdisk to GPT and for which no space was reseved for EFI or grub2 partitions? Is it required to move existing partitions to make space for UEFI or grub2 partitions at the beginning of the disk?
How can I tell grub2 to copy to an (external) SSD disk the contents of a Windows UEFI partition in an adapted form so it can boot in standalone boot as external SSD on a different PC/Laptop without Windows? Copying the partition with cp, tar or dd and calling grub-install did not work for me so far – resulting in the errors below. Must the flag --removable be used for an SSD?
 3. Ideally, I would like to create a multi-boot system with Windows 10 and different Linux variants – all bootable by grub2. How do I do this to run as smoothly as possible?

  a) What should I do before installing Windows 10? Should I create a small GPT partition for grub2 and mark it as such? Should I create different EFI partitions, e.g. for Windows and the different Linux variants?

 b) Should I install Windows 10 before any Linux or vice versa?

 c) Is it possible to put an EFI partition into the logical partition space on an MBR SSD, e.g. as /dev/sda5?

 d) Must an EFI partition or a small GPT partition for grub2 be the first one on the disk/SSD (as some contradictory sources claim)?

 e) Is there an easy way to integrate a /boot partition back into the main Linux installation and telling grub2 about it? I figure that the hard way – once the grub2 install works – is to adapt the grub.cfg file accordingly and copying the files together into one partition.

I’m trying to repair a broken grub2 boot in /dev/sdb with any of the recent Ubuntu versions: I prepared these statements:
Configuration: /boot = /dev/sdb1, / = /dev/sdb3, UEFI = /dev/sdb4 (is created by this script)

    sudo fdisk  /dev/sdb # possibly convert to GPT; create partition 4 of type EFI: code ef
    sudo gdisk  /dev/sdb # create partition 4 of type EFI: code ef00
    sudo partprobe
    sudo mkdir -p /tmp/lin1/mnt/boot
    sudo mount -o nouuid /dev/sdb3 /tmp/lin1
    sudo mount -o nouuid /dev/sdb1 /tmp/lin1/boot
    sudo mkdir /tmp/lin1/mnt/boot
    sudo mkfs.fat  /dev/sdb4
    sudo mkdir -p /tmp/lin1/mnt/efi
    sudo mount -o nouuid /dev/sdb4  /tmp/lin1/mnt/efi
    sudo mount -o nouuid /dev/sdb1  /tmp/lin1/boot
    sudo bash -c 'for i in /dev /dev/pts /proc /sys /run /sys/firmware/efi/efivars /bin /usr /var /etc; do mkdir -p  /tmp/lin1$i; done'
    sudo bash -c 'for i in /dev /dev/pts /proc /sys /run /sys/firmware/efi/efivars /bin /usr /var /etc; do mount -o nouuid -B $i /tmp/lin1$i; done'
    sudo chroot  /tmp/lin1/
    sudo grub-install --efi-directory=/tmp/lin1/mnt/efi --boot-directory=/tmp/lin1/boot --target=x86_64-efi /dev/sdb
    sudo bash -c 'for i in /dev /dev/pts /proc /sys /run /sys/firmware/efi/efivars /bin /usr /var /etc; do umount  /tmp/lin1$i; done'
    sudo umount /tmp/lin1/mnt/boot
    sudo umount /tmp/lin1/boot
    sudo umount /tmp/lin1/
    sudo sync
    sudo hdparm -Y /dev/sdb

I run into these 7 problems (these problems all occur occasionally after pretty much the same grub-install as shown above, depending on host system, Ubuntu version, additional Windows10 UEFI partition present and if the SSD is connected internally or externally):

 1. At boot time: a start job is running for /dev/disk/by-uuid/…. (also
    after adapting the block ids in /etc/fstab)

   

 2. Ubuntu systemd: Received SIGRTMIN+20 from PID (plymouthd)**

 3. Ubuntu kernel: ucsi_ccg 0-0008: failed to reset PPM!
 4. Ubuntu kernel: ucsi_ccg 0-0008: PPM init failed (-110)
 5. Grub: error: file ‘/grub2/i386-pc/normal.mod’ not found  - Entering rescue mode (the normal Ubuntu 2019.04 x64 EFI install
    directory is /grub/x86_64-efi)
 6. Grub boot:**

    Dependency failed for File System Check on /dev/disk/by-uuid/CA82-D0E8
    Dependency failed for /boot/efi

 7. chroot: failed to run command ‘/usr/bin/bash’: No such file or directory:

Problematic Part:

    soc1@soc1-MS-7B17:/bin$ sudo chroot /tmp/lin1/ /usr/bin/bash
    chroot: failed to run command ‘/usr/bin/bash’: No such file or directory
    soc1@soc1-MS-7B17:/bin$ ll /usr/bin/bash
    -rwxr-xr-x 1 root root 1113504 Nov 20 20:00 /usr/bin/bash*
    soc1@soc1-MS-7B17:/bin$ ll /bin/bash
    -rwxr-xr-x 1 root root 1113504 Jun 7 00:28 /bin/bash*
