I'm trying to install Ubuntu (version 20) on a USB drive using a Dell computer with Intel Rapid Storage Technology (RST). The Ubuntu installer complains about a conflict with Intel RST and I'm directed to the following page which suggests how one might resolve this but, from what I can see, with significant risk to the Windows OS already installed:

https://discourse.ubuntu.com/t/ubuntu-installation-on-computers-with-intel-r-rst-enabled/15347?_ga=2.46699879.1733397468.1588515427-430611100.1559067266

Given the risks, I do not want to meddle with the BIOS settings as suggested. I am trying to install on a USB drive so theoretically it shouldn't matter about the configuration of the internal SSD. Is there a way to get around this check so I can proceed with the installation onto my USB drive?

  • You can temporarily turn it off, then turn it back on after you install. But see these: Intel Optane - See Intel response that no performance difference between RAID & AHCI. communities.intel.com/thread/121155 & dell.com/community/Laptops-General-Read-Only/… You need to partition in advance and either turn off internal drive or see this work around to get Ubiquity to install to external drive.

    RSTe is not designed for Linux.Set the BIOS to use AHCI instead.

  • @oldfred I'm concerned about the risks to the existing Windows installation in turning RST off. Is there any risk in turning the internal hard drive off temporarily? Is the idea that the installer will then proceed past the RST check and allow me to install on my USB drive?

  • At most you may have to reinstall a Windows UEFI boot loader. UEFI forgets UEFI boot entries. It always seems to lose Ubuntu entrys, but almost all systems seem to look in ESP and find Windows when a drive is plugged back in. Everyone dual booting with Windows is using AHCI. But as with all major system changes, you need to have good backups, and a Windows repair/recovery flash drive.

  • @oldfred Thanks for your help with this. You can tell I'm a bit unsure about a lot of this. I have borrowed a laptop using AHCI and have been able to use it to install Ubuntu on my USB stick. I thought this was progress but while the USB boots up on this borrowed machine, on my machine the USB drive is not shown in the BIOS boot menu. Do you know of a way I can get my machine (using RST) to recognise the USB as bootable?

I was a bit "scared" by the options detailed above. While I have made back-ups of my data and have a repair/recovery flash drive, it'd be a hassle having to go through this and something I was keen to avoid. My solution in the end was to install Linux as a virtual machine using VirtualBox. This worked a treat without any conflict and is actually better than the dual-boot solution I was pursuing originally because it allows me to run the two operating systems simultaneously.
