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.

This is exactly the problem! The big aim is to make it seen for all computer during the boot of the machine by the BIOS (F12,...) to select which device/media/.. to boot/start. |

Hi Guys!
All the trick is here to be seen by the bios during the power up of the machine.
Code:
DETECTED BY BIOS !!!!
Disk debian-8.1.0-i386-xfce-CD-1.iso: 676 MB, 676331520 bytes
255 heads, 63 sectors/track, 82 cylinders, total 1320960 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x639f344e
Device Boot Start End Blocks Id System
debian-8.1.0-i386-xfce-CD-1.iso1 * 0 1320959 660480 0 Empty
debian-8.1.0-i386-xfce-CD-1.iso2 8428 9067 320 ef EFI (FAT-12/16/32)
NOT DETECTED BY BIOS !!!!
Disk live/linuxmint-17.2-xfce-32bit.iso: 1474 MB, 1474297856 bytes
64 heads, 32 sectors/track, 1406 cylinders, total 2879488 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x5a5982d9
Device Boot Start End Blocks Id System
live/linuxmint-17.2-xfce-32bit.iso1 * 0 2879487 1439744 17 Hidden HPFS/NTFS
https://www.adayinthelifeof.nl/2011/...l-disk-images/
Some possible eventual idea:
Code:
Device Boot Start End Blocks Id System
linuxmint-17.2-xfce-32bit.iso1 * 0 2879487 1439744 17 Hidden HPFS/NTFS
dd if=/dev/zero of=linux-image.img bs=1024 count=1724288
Device Boot Start End Blocks Id System
linux-image.img1 2048 2879487 1438720 83 Linux
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
losetup -o 106496 --sizelimit 1474297344 /dev/loop2 linux-image.img
losetup -o 1474297856 --sizelimit 1765670400 /dev/loop3 linux-image.img
mkfs.ext2 /dev/loop2
mkfs.ext2 /dev/loop3
fdisk linux-image.img
Command (m for help): p
Disk linux-image.img: 1765 MB, 1765670912 bytes
255 heads, 63 sectors/track, 214 cylinders, total 3448576 sectors

Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x8133a058
Device Boot Start End Blocks Id System
linux-image.img1 * 2048 2879487 1438720 83 Linux
linux-image.img2 2879488 3448575 284544 83 Linux
no!! => dd if=linuxmint-17.2-xfce-32bit.iso of=/dev/loop2
../debian-8.1.0-i386-xfce-CD-1.iso2 start8428 9067 320 ef EFI (FAT-12/16/32)
Device Boot Start End Blocks Id System
linuxmint-17.2-xfce-32bit.iso1 * start0 end 2879487 1439744 17 Hidden HPFS/NTFS
8428 -> 4315136
9067 -> 4642304
mint:
2879487 -> 1474297344
mknod -m0660 /dev/loop17 b 7 17
losetup -o 0 --sizelimit 1474297344 /dev/loop17 linuxmint-17.2-xfce-32bit.iso
