Hi everybody,
I suggest that we try to make a Lubuntu iso file, that can boot in
'all' computers with intel/amd CPUs.
Why? I fail to see any benefit from this.
I think it is good to have a portable live or persistent live system on
a USB pendrive. You need not carry a computer, only the pendrive, and
you can borrow almost any computer to run it.
It used to be possible with 32-bit systems, but now there are more
and more UEFI systems, which need a 64-bit version to boot. Many of
them can be switched between UEFI and CSM, but some are locked to
UEFI. This limits the portability of live CD/USB drives and
persistent live USB drives, they work
- either 32-bits iso files for 'all' non-uefi systems - or 64-bits
iso files for 'all' 64-bit systems.
Which seems perfectly reasonable to me.
Reasonable if you intend to use it to install, but it is better for a
portable system, if there are no such limits.
What would be needed to make a 32-bit system 'licensed' to run in
UEFI?
What makes you think you need anything licensed to boot with UEFI?
Reading the discussions about UEFI, and how people are trying to make it
dual boot with Windows 8 in UEFI. Maybe licensed is the wrong term,
maybe the term is 'a key'.
Try to boot a USB drive, any 32-bit Ubuntu family version! It will not
work. All these USB pendrives work when I switch UEFI off. But this is
not possible in some computers.
Clonezilla i686-pae boots from CD, Lubuntu 12.04 i386 non-pae boots
neither from CD nor USB. Lubuntu 12.04 64-bits boots from CD. Ubuntu
12.04.2 boots from USB, but I think it is 'licensed'. A brand new
download of debian-live-7.0.0-amd64-lxde-desktop.iso does not boot from
USB, but it boot fine when no UEFI.
I tried recently with a grub2 and iso system in a USB pendrive. I
could boot it in my Toshiba with UEFI (with a complaint, but it
booted), but after booting into Windows, the 'grub2 and iso pendrive'
was no longer bootable. Maybe it was blacklisted by some UEFI
janitor, maybe something was overwritten. So I think such a generally
portable live system needs to be created in a professional way with
the licensing tools, that are used in the 64-bit iso files.
With out any error messages etc. this could be totally unrelated to UEFI.
I can try again, but what I know is that for example Ubuntu 12.04.2
boots from USB repeatedly without any problems. A 32-bit system with the
same 'license' or 'key' should work too, and would be a good candidate
for a truly portable system.
I think an iso for 'all' intel/amd computers would be interesting
also for Xubuntu.
I'm willing to test it in low-end and high-end computers, but I
don't know how to create it.
