Cloned Identical HD's - How to know which is booted?
by Fairway from LinuxQuestions.org on (#4ZQ6Z)
Dual Boot Win10 / Ubuntu 18.04.4 System has been running great. Added a M2 Nvme SSD and cloned it with the original installed SATA HD. I can read/write to both drives.
Grub shows the Windows 10 and Ubuntu on /dev/SDA/1 (SATA) as well as the Win 10 and Ubuntu on the /dev/Nvme. (Both are 1Tb drives).
How do I confirm Im actually booting to the nvme (even though I cursor down the Grub selections and select that option).
I haven't done the obvious "disconnect one and see if it still boots method yet and thought there would be an easier way.
How can i confirm I am booting to the nvme SSD and not the old SATA?
Thanks F
