Qubes 4.2-rc5 update did not generate the initramfs images in the system partition /EFI/qubes. Broken installation, I can’t boot anymore

For those who come across this post, the problem was something else, not related to Qubes. Ubuntu installed on another disk, automatically over-writes the boot partition of Qubes:

Qubes-OS in one SSD, and Linux in another SSD. Any problem?

I knew Qubes created different partitions on the same hard drive. I have an Alienware 15 r2 which has two drives. Using Legacy mode I have installed Qubes to the SSD, and Windows 10 to the spinning drive. (forgive me, I must have Windows for one or two uses) I do not recommend Alienware for use with any Linux. The XPS that can come with a Linux desktop, well, not as secure as using Heads. All I can say is: If one only has one drive. “Windows does not play well with others.”

This seems to be a bug.
