Intel Clear Linux tolerates drive switching, Debian gives "Missing OS GRUB"
by iamnoex from LinuxQuestions.org on (#5P3SA)
I have a number of drives that are connected to the power supply by DPDT switches, including a pair of boot drives that can be toggled (when the system is powered down). One drive has a Windows 7 installation and on the other I installed Debian 11 from the Live image.
The Debian install went smoothly and I made a number of reboots. However, after switching to the Window 7 drive and back to Debian I get a "Missing OS GRUB" message. On the other hand if I install Intel Clear Linux from the Live image, I can toggle back and forth without losing the Linux installation. The Windows 7 installation is not disturbed by any of this.
This seems to be an issue involving UEFI and GRUB that affects Debian but not Clear Linux. What can I do to remedy the situation for the Debian boot drive? Is there another distro besides Clear Linux that would tolerate the switching process?
