I have ubuntu running smoothly on my internal NVME drive. I want to install ubuntu on ny external SSD also.

So I went ahead and installed it on the drive using manual partitioning (efi, swap, and root)

After the installation the first issue I faced is my internal drive’s grub is messing with my external drive’s grub. There are multiple grub entries. When I loaded the system in the grub menu there are two options run ubuntu or run ubuntu on nvme partition. When I click on first ubuntu it says load the kernel module first. I went to the boot sequence deleted all the grub entries. Created a new entry. Somehow after some random tries external drive’s ubuntu booted successful.

But there are issues terminal is not opening so I went ahead and did reinstallation. Again I somehow booted into external drive’s ubuntu while starting I saw some decompression errors and then GUI popped up with system encountered some errors and it is not loading. But cli mode (alt + f3) is working fine.

I am not able to understand what’s the issue here. I also checked the ISO’s checksum as I thought the iso might have been corrupt but its correct.

  1. I want to understand how grub will work in this case. There are many articles for windows + linux but none for linux + linux installation
  2. I want to make it work seamlessly in GUI mode
