I installed a second "Felicia2" in hd2, at partitions it identifies as sdc11 & sdc12 on Sunday and set it up as I like it. Recovered from hibernation yesterday but today -> BusyBox!
Tried Recovery mode, boot log on screen says sdc11 not found. Higher up, it has scanned drives and found what it calls sdd with partitions 1, 2, (5, 6, 7, 8, 9, 10, 11, 12) - That is clearly hd2.
So I have booted into "Felicia1" in hd0, at partitions it sees as sdb2 & sdb4. (No extended partition). [Swap partitions ignored in this report].
Felicia1 in hd0 has /boot/grub/device.map showing sdb,c,d; Felicia2 in hd2 has /boot/grub/device map showing sda,b,c. There is no sdd here.
So why did the bootloader working from grub in Felicia2 see hd2 as sdd?
This question links with erratic behaviour of installer: sometimes it sets /boot/grub/device.map with my 3 hd's identified as sda, sdb, sdc; sometimes as sdb, sdc, and sdd.
