I have a dual boot system (Windows 10 and Ubuntu 21)
Lenovo Z50-70
I upgraded my storage to Samsung 870 QVO 1TB.
When I reboot the machine via Windows, the machine reboots normally and
SSD is detected. However, when I reboot the machine via Ubuntu, the
machine will reboot but it won't detect my SSD.
I have upgraded to the latest Ubuntu distro and have the latest kernels,
etc... I have validated that my installation and boot partitions are
correct.
Other people who faced an issue similar to mine were using SSDs with
NVME. However, my SSD is SATA based, not NVME so neither applying the
fix I found about setting nvme latency nor upgrading distro have solved
the problem.
On Windows, I had initially the same problem but on Windows after
selecting AHCI Standard SATA mode, the issue was solved. On Ubuntu, I'm
already in AHCI mode but the problem persists. I did few times grub boot
repair to validate if it was something messed up with my boot
configurations but turned out that it's not.
I'm able to use Ubuntu 21 at the moment. However, I'm unable to perform
a reboot. Every time I have to shut down the machine and then manually
push the laptop's button to launch it again because if I accidentally
hit reboot via Ubuntu, the machine will not find SSD and on next boot,
the BIOS falls back into Windows Boot Manager and I have to run grub
boot repair all over again via live USB.
I hope that you will find a solution for this problem soon.
