[13:07] <Dan> Hi, quick question on providing some feedback on the information presented on https://help.ubuntu.com/rst/, The intro write up is great, the procedure for changing from RST to ACHI is excessevily complicated and actually does not work as described.  I found a very simple process on DELL's help posts here
[13:07] <Dan> https://www.dell.com/community/Desktops-General-Read-Only/AHCI-disabled-on-XPS-8900-desktop/td-p/4673037   in summary use MSCONFIG to select safe boot mode, shutdown, boot to BIOS, change SATA operation from RST to ACHI, reboot, use MSCONFIG to deselect safemode boot, reboot -- done
