Z370 classified K device cannot detect Ubuntu SSD
I previously could locate Ubuntu in my boot override list within the BIOS, but it seems to have vanished. I haven’t updated either Ubuntu or the BIOS. The OS is now on a different drive, specifically a secondary SSD, yet it still isn’t visible. Can I make a drive appear during startup? If not, is there a way to ensure Windows 10 adds Ubuntu to the boot selection?
You need to reinstall GRUB. This can be done using a live ISO or by starting Ubuntu with Refind.
You want to deploy Refind on the live storage and execute it in that environment?
Refind is a bootloader that also functions as a live USB. It can start Ubuntu automatically if you haven’t used crypt. If your new SSD matches another model, you might mount its EFI partition from Windows using DiskPart, copy the GRUB file, and then mount the second SSD’s EFI partition with the same GRUB setup. Remember the first partition must be labeled EFI.
I believe I resolved the issue, but my BIOS isn’t showing the separate SSD as a boot choice. I’m currently using grub2win, which is really slow and causes my boot time to increase significantly.
It would have been more advantageous to start with the Refind live USB and then install GRUB via the Ubuntu command line or set up GRUB directly on a live Linux system. Still, you were lucky to discover a workaround. In Linux, it’s preferable to handle problems independently.
