No, it's just fdisk trying to guess the type of a filesystem that isn't

 It definitely works here, and fdisk shows it to be a hybrid image. You
 are writing it to the USB device itself and not a partition on it?

Yeah, I'm sure. But it might be a weird BIOS problem, since I can only
boot from USB sticks when they're sticked into a USB slot at the back.

There's some more straws to grasp, namely the partition table that the
OP created with fdisk, as well as the first partition on it:

Assuming the USB is still on /dev/sdb, then use fdisk to delete
partition /dev/sdb1.

Then manually delete the USB DOS partition table:

dd if=/dev/zero of=/dev/sdb bs=512 count=1


Finally, reinstall the iso once more without creating any partitions manually:

dd if=/home/joseph/Downloads/install-amd64-minimal-20140828.iso of=/dev/sdb

sync

NOTE: Make sure that /dev/sdb is indeed your USB stick or you'll cause damage
to whatever is on /dev/sdb.

If I recall correctly, when I make my sysrescue USB stick, I don't
create anything.  I just run the script.  If I am updating it, I use dd
to erase everything off the stick then run the script.  I don't recall
creating partitions or anything tho. 

I'm sure this will be figured out eventually.  It's likely some small
thing that makes a big difference.  We have all been there before.

  Joseph, I am assuming you are trying to create an install disk? If so,
  you shouldn't have to do all these steps. I normally just download the
  minimal install ISO and write it to a USB drive with the following
  commands:
  
  # dd if=/path/to/minimal-install.iso of=/path/to/usb-drive bs=4096
  # sync
  
  You don't have to mount the USB drive. Use sync to ensure that all the
  data has actually been written to the device before you remove it.
  
  I have run across problems with some ISO files that don't play nice
  with this method, but this one seems to work well with the Gentoo
  minimal CD. Also, keep in mind that you don't really need to have the
  Gentoo install disc to install Gentoo. It's certainly EASIER to follow
  the handbook when you have the minimal install disc, but just about any
  Linux live CD will work as long as the architecture matches (chroot
  from x86 to amd64, for example, will not work). Anyway, if this is not
  what you are trying to do, maybe you can give us more details.
  
  I run it on 1MB USB stick, it did not work:
  dd if=/path/to/minimal-install.iso of=/path/to/usb-drive bs=4096
  sync
  
  I think the dd will work with LiveDVD but not liveCD.
 
 Why not use unetbootin?

 and their scrip made the bootable USB just fine, it works.
 But it bugs me that Gentoo instruction didn't work.

Best thing to do:
Check that that script actually does and figure out which step(s) are

Hi,

Just wanna say few words to clarify few things about bootstraping. If you know 
what you are doing, this all is very simple.

What you need for a working system is a working root filesystem that contains 
all the scripts, modules and executables. A minimal cd contains this. You could 
also use stage3 tar ball.

Then you need a working kernel image and possibly a initrd. There is a working 
kernel on minimal cd.

All begins with boot loader. That loader is loaded by BIOS first. Then boot 
loader starts executing and loads kernel with right parameters. Kernel takes 
over and loads rootfs and so on.

On normal disk (USB, sata, ATA, SCSI (and DVD i think)) you have a normal MBR 
(first 512 bytes of disk) which BIOS loads to 0x07C0 address in memory and 
starts executing. So just install boot loader (like grub) to the beginning of 
the disk and it will boot. With right commands/config you can load the kernel 
correctly and boot.

CD is different. BIOS can't read ISO file system. For CD boot you will need to 
create image of a floppy-disk and install your boot loader into that image. The 
boot loader has to have drivers to read the real ISO file system so that it can 
load the kernel into memory and boot. Because of this a plain cd isoimage is 
unbootable although all necessary stuff is there. It is easily arranged so that 
it becomes a bootable USB disk.

This is odd as you have created a bootable USB stick. Are you using EFI?

If not, does your BIOS have options for booting from different devices,
USB CD, USB HD, USB Zip, etc? You may need to try different
alternatives, one system I have wants to boot USB sticks as Zip

A couple days ago someone mentioned ArchLinux's ISO - in the interim,
you *could* use that if you just need something right now. The gentoo
devs are great, but the ArchLinux devs produce an amazing ISO - it
supports 32 and 64-bit as well as both non-EFI and EFI boot. Then it's
just a simple 'dd if=path/to/archlinux.iso of=/dev/sdX  sync'. I've
used the archlinux iso to install Gentoo since forever purely for this
reason.

Yes, I thought you'd say that. I think you have something odd in your BIOS, 
which is objecting to (or not recognising) some feature of the various 
bootable ISOs you put on that stick. Is it a very old BIOS? I remember you did 
say it was an old machine.

You may simply have to accept that some things will boot, others not.

How does the output of fdisk -l from the sysreccd stick compare with that
from the Gentoo stick? What happens when you try to boot the Gentoo USB
stick? I think you've already been asked that but I don't recall seeing
an answer.

I'm inclined to blame your motherboard's USB controller for this failure

 No, it's just fdisk trying to guess the type of a filesystem that isn't

 There's some more straws to grasp, namely the partition table that the
 OP created with fdisk, as well as the first partition on it:

 Assuming the USB is still on /dev/sdb, then use fdisk to delete
 partition /dev/sdb1.

 Then manually delete the USB DOS partition table:

 dd if=/dev/zero of=/dev/sdb bs=512 count=1


 Finally, reinstall the iso once more without creating any partitions
 manually:

 dd if=/home/joseph/Downloads/install-amd64-minimal-20140828.iso
 of=/dev/sdb

 sync

 NOTE: Make sure that /dev/sdb is indeed your USB stick or you'll cause
 damage
 to whatever is on /dev/sdb.

 What actually happens when you try to boot ?
 do you get any messages?
 some bios will require you to specify usb boot device type of cdrom or
 hard disk
 do you have a press F11 for boot choices menu or similar?
 it could be that you have usb cdrom selected as primary boot device, ide
 disk as secondary and then other removables after this.
 please confirm your bios boot orders


 Booting sequence is USB and HD.  If I will not insert bootable USB it
 will boot from HD
 It works, as the bootable USB I created with Systemrescue CD script it
 worked.  When I plug in the USB stick it boots from it.

However, there is a difference between USB-CDROM and USB-HDD and USB-FDD
each of these is a different type of device.
which is set in your BIOS ?
the systemrescue-cd must be a version that your bios recognises, if your
bios doesn't like USB-HDD boot then that is most likely the issue you have.

have you tried installing grub2 and doing a direct iso boot ?  the
gentoo minimal install cd support doing this for a long time now, and is
my preferred route as you can load on the iso images and just change the
grub conf menus

It is very confusing.
The box 1.) (above) I was testing it on my old USB stick I generated few years ago (it boots OK), it boots USB stick generated by Systemrescue CD.

It does not boot USB stick I generated a new one (manually), nor does it boot USB stick
generated by DD or UNetbootin

The second box after checking second time it boots USB stick generated by dd

How do you generate a USB stick manually? What does that even mean?
 
 The second box after checking second time it boots USB stick generated
 by dd and Systemrescue CD but it will not boot USB stick generated
 manually or by UNetbootin

UNetbootin only works with some distros, it is not a universal solution
like hybrid ISOs. IMO it is redundant now we have hybrid ISOs and in my
experience, very few distros are not hybrid nowadays. So forget
Unetbootin.
 
 Apology the this long thread, but I'm still confused.  I could
 understand why it would not boot USB stick generated manually but why
 it will not boot USB stick generatd by UNetbootin but it boots stick

Because they create the stick in different ways, and there are several
different types of USB device to emulate when doing so. If the only ISO
that will boot from your computer on a USB stick is System Rescue Cd, use
that. It's one of the best distros for installing Gentoo anyway.

  A USB stick is ***NOT*** a zip-drive or a floppy drive.  That could be

They would make more sense.

  Then the USB key shows up as an option in the boot-order menu...

It is my observation with many (if not all) of my systems that the USB stick
was in fact not considered a USB device but an HDD. So to boot from a stick,
instead of changing the boot order to USB → HDD → CD-Rom → whatever I had to
put HDD at the top and then – within the HDD selection – move the USB stick
above the internal HDD. But then again, those were mostly laptops, whose
BIOSes always seemed very crippled to me.

If you run sync and the prompt comes back for the next command, then
sync should be finished.  I guess one could try the eject command too. 
I think, THINK, it makes sure things are synced before it finishes.

 You don't have to mount the USB drive. Use sync to ensure that all the
 data has actually been written to the device before you remove it.

The ISO image has to be created as a hybrid image for this to work. Use
isohybrid from syslinux to convert non-hybrid images. You can easily test
if an ISO image is hybrid with fdisk -l, if it shows a partition table
the image is hybrid.

 Joseph, I am assuming you are trying to create an install disk? If so,

 commands:

 You don't have to mount the USB drive. Use sync to ensure that all the
 data has actually been written to the device before you remove it.
 
 I have run across problems with some ISO files that don't play nice
 with this method, but this one seems to work well with the Gentoo
 minimal CD. Also, keep in mind that you don't really need to have the
 Gentoo install disc to install Gentoo. It's certainly EASIER to follow
 the handbook when you have the minimal install disc, but just about any
 Linux live CD will work as long as the architecture matches (chroot
 from x86 to amd64, for example, will not work). Anyway, if this is not
 what you are trying to do, maybe you can give us more details.
 
 I run it on 1MB USB stick, it did not work:
 dd if=/path/to/minimal-install.iso of=/path/to/usb-drive bs=4096
 sync
 
 I think the dd will work with LiveDVD but not liveCD.

Why not use unetbootin?

I'm pretty sure the Gentoo minimal image is - I've been dd'ing the iso's for

Besides, running `fdisk -l /path/to/image.iso` does return a partition list

As mentioned by Alan, you haven't clarified what you meant by 1MB USB stick

The conversion process is non-destructive, it uses space normally unused
on a CD/DVD ISO, so the process is safe on any ISO. I've used it on
dozens of ISOs distributed to tens of thousands of users and not had a
single complaint yet.

In my experience, anything over 4k makes little or no difference. The
filesystems have a 4k block size, so the default of 512 is dead slow, but
once you hit the block size the improvments stop.

I usually use dcfldd these days, which seems to do a good job of working

Joseph, I am assuming you are trying to create an install disk? If so,
you shouldn't have to do all these steps. I normally just download the
minimal install ISO and write it to a USB drive with the following
commands:

# dd if=/path/to/minimal-install.iso of=/path/to/usb-drive bs=4096
# sync

You don't have to mount the USB drive. Use sync to ensure that all the

[snip]

Some ISO images already have the appropriate boot sector; for example, Arch Linux ISOs. In this case, all you need is to write the image using dd ... of=/dev/sda or 
similar. 

But if the ISO image is not specially prepared (like Gentoo minimal ISO's) to be used from a USB drive, you need to copy the .iso file to the disk as an 
ordinary file – mount, cp, all that – and install a bootloader such as Syslinux or lilo or GRUB. 


Unfortunately the instruction on Gentoo Wiki is missing something, so it 
doesn't work either.

it doesn't work :-/

You didn't answer this.


Yes, when I writ the image to USB the USB is not mounted.
USB is /dev/sda1
and I'm writing it to /dev/sda




Yes, you MUST run sync after dd. When I tested the minimal install
image just now, dd returned after less than two seconds. sync took a
little longer...



Yes, I did use sync after dd makes no difference.


Have you tried this with more than one drive, to rule out hardware
problems?


Well, I don't expect USB to be a problem as SystemrescueCD can generate bootable USB on the same stick and it boots correctly; so I don't suspect hardware to be an 
issue.

Just to make sure, you don't use UEFI on your host do you? The gentoo minimal 
CD doesn't support UEFI as yet (whereas I think sysrescd does).

 unetbootin uses some $MAGIC that doesn't work with all ISOs. isohybrid
 seems to work with everything and is much simpler to use too.
 
 I just tried it as root:
 isohybrid  install-amd64-minimal-20140828.iso
 dd if=/home/joseph/Downloads/install-amd64-minimal-20140828.iso of=/dev/sda

This is rather strange.

What do you see when you run 

 fdisk -l /dev/sda

*after* you have completed dd and sync as you show above?
