Title:
Ubuntu32bit generally cannot work on 64bit UEFI computers so
Ubiquity32bit should warn the user when EFI can be detected
Status in Ubuntu Website Product:
Fix Released
Status in “ubiquity” package in Ubuntu:
New
Bug description:
ALL THIS BUG DESCRIPTION CONCERNS ONLY 64bit UEFI COMPUTERS
(= most of Windows8 computers, so sadly most of recent computers)
we have 2 big issues:
1) Ubuntu-32bit ISOs cannot boot in UEFI mode (bug #1025555 ), so
Ubuntu32bit will always be installed in Legacy (non-UEFI) mode. Thus,
Ubuntu32bit cannot boot after installing it, except if we install an
UEFI bootloader such as grub-efi.
2) According to comment 7 of Bug #1020446 , 64-bit UEFI firmwares
generally will only load a 64 bit boot loader. This is a limitation of
the firmware.
So in most cases, installing Ubuntu-32bit fails, and there is no way to make it work !!!
(except if we turn the firmware in Legacy mode, but in this case Windows8 won't boot any more...)
I let Ubuntu devs find a solution, but I'd suggest that the installer (Ubiquity) of 32bit ISOs should strongly recommend to install a 64bit ISO instead. (AND ubuntu download page should propose 64bit by default.)
