Re: Failed to switch root

Wednesday, 26 June 2019

Hello,

In conclusion "temporally".
1) I could not boot on the first OS installed because 
linux instead of linuxefi 
and
initrd instead of initrdefi were used in the menuentry
If seems that moving from fedora 28 to fedora 30,
a) the grub.cfg generated does not keep track
b) acually, the new generation of grub.cfg (after the transition)
does not manage any menuentry.
2) When a grub.cfg is generate with grub2-mkconfig, even if multi
boot are detected (like on 2 different HDs), during the grub menu,
it is only possible to choice the boot kernels from the OS which
has generated the grub.cfg.
3) How to access to the other entries (ie on the OS sitting on the 
other HD)?  Using efiboofmgr -c
Here is efibootmgr
