Installing Ubuntu 20.04 on dual boot windows HP Envy consumer laptop. Got the error to disable RST. Consumer HP lap with insyde bios f.47 which does not allow "Advanced option" to disable RST and change to AHCI. Dont want to mod the BIOS. I disabled optane memory via Windows APP. but no luck. same laptop was running Ubuntu 18.04 without any issue. is there a way to bypass the RST check by Unbuntu installer. Thanks
I have Win 10 and wanted to do the same. What I did was logged into BIOS and switched RAID ON to AHCI. Then I made sure and booted to the USB, and installed 20.04 to replace 18.04 (the first option). Reboot into your new install of Ubuntu (still in AHCI) and go to 'Drives'. Set your windows drive/partitions not to automatically mount on system startup. Then you can reboot, go into BIOS and switch back to RAID ON. Now windows will boot fine and so will Ubuntu. If you don't set your windows drives to NOT boot automatically in Ubuntu then with RAID ON Ubuntu will spend a minute at the spash screen trying to find the hidden drives. Works fine, just a little awkward that you can't just install 20.04 with RSK enabled.
