Linux LIVE Distro with great UEFI Support !! (debian like)

Hello

I have tried debian installed xfce and it has a great uefi support. I can install debian without any single problem.

However DEBIAN LIVE has no support of UEFI. You cannot see the pendrive into the menu bios to boot!

I just tried makululinux and again the same. A live without uefi.

A particularity to boot well with UEFI is the ISO (image) live with 2 partitions (such as debian installer stable).

Well, if you know, any please help us !!!!!!!!!!!

looking forward having a nice answer to not found results.

The problem with booting to uefi dvd sometimes is you have to select a uefi source if that is possible on your system.

There are many web pages on uefi and non are exactly the same some suggest that you do this or that on your uefi settings but as far as I've seen, there are no two uefi systems alike.

I use a Fedora 22 live system and that boots fine in UEFI mode.

thank you. It actually narrowly depends the bios version. The AMT bios of various machines are more or less different. Some of them are fine with UEFI. Today I could boot the last mint distro with uefi without a problem, however if you use another pc, this same flashdisk will not be detected by the bios boot menu.

You know, ... I did a live with SYSLINUX and UEFI, and it sounds even better than the LIVE of Mint.

Syslinux vs grub2, actually syslinux is comfortable and could boot even better and it is more reliable on uefi's.

From my experience with getting UEFI to work, probably comes down to if hybrid is turned on by default in the firmware version. With hybrid turned on, most live images will try to boot as a legacy system, even though while it allows for legacy booting, it's not in any way easy to get legacy booting. Needs to be fully legacy boot, or fully UEFI with the hybrid option/allow legacy roms option turned off so that it will ONLY do UEFI boot. Again, that's just what I've seen in everything I've used.

Hi Guys!

All the trick is here to be seen by the bios during the power up of the machine.

Code:

Some possible eventual idea:

linux-image.img2        2879488    3448575      284544  83  Linux



    2048    2879487 

 => 106496

=>  1474297344



  2879488    3448575  

2879488        gives 1474297856

3448575        gives 1765670400



then create loopback devices:

 mknod -m0660 /dev/loop5 b 7 5
