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.

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
Units = sectors of 1 * 512 = 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

          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)
