Sugar on a Stick not booting into Sugar

[CarolineM]

​http://download.sugarlabs.org/soas/snapshots/1/Soas-200902231225.iso

Created on windows with Fedora usb creator.

Boots through Fedora 10 starup then.

WARNING: Cannot find root file system

Create symlink /dev/root and then exist this shell to continue the boot sequence.

bash: no job control in this shell

Have seen the same thing on my own laptop (Dell Precision M60).
What helps for me is to remove the usb stick and then insert it again.
Wait for all the messages (identifying the stick and recognizing
the device, /dev/sdb in my case).
Then hit return so you get the shell prompt.
Exit the shell (e.g. using Control-D).
For me boot continues and the sugar UI appears.

My guess is that the stick is not properly dismounted
at shutdown due to the computer shutting down too fast
and removing power to the USB stick before it is finished
flushing the data.

I used the same stick on other laptops which did not show
this behavior.

This problem occurs when you create the stick on windows, then remove the stick after flashing without ejecting it first from windows.

I added a note about this to the Windows Installation instructions.

This happened to me today with a USB stick that had been working through at least 2 reboots then I took it into the field and it gave me this error.

Any Fedora guy could tell me what's the chance of getting this issue fixed by reproducing with a true fedora live image and filing a bug in ​https://bugzilla.redhat.com/ ?

I am still having this problem on the 2/28 snapshot. Even being very careful to always properly eject the USB I can't create a working stick.

Results when I take out and put in the USB stick after initial failure

I am seeing this intermittantly on my laptop. Tonight i have a stick that does not boot my laptop but does boot a desktop.

Do we know what the root cause of this problem might be?

Today I saw this when I created a SoaS1 -3/21 stick.
First time I formated with FAT32
Error.

I reformatted with FAT and it worked.

However, as this problem has been so internment for me I am not at all sure the FAT32/FAT was the difference.

I had this problem today with a stick that was formatted FAT

More interesting data.

I made a stick with the windows fedora USB Creator.
Then I made another one.
The second one failed.
Then I reformatted it FAT and it still failed
Then I reformatted in FAT and restarted the USB Creator and had success.

I find liveusb-creator in Fedora 11b needs to be closed and restarted EACH time it is used or it may fail

Can you report it in ​https://fedorahosted.org/liveusb-creator/ and link it form this ticket? You will need to register there in order to submit a ticket.

Thanks!

I haven't seen this issue in a while so I'm going to close for now.

Some comments from #fedora-devel:

(16:32:51) bernie: has anyone tried booting live fedora usb sticks on macbooks recently?
(16:33:33) wwoods: bernie: that ain't gonna work.
(16:33:54) jeremy: bernie: macbooks don't boot from USB unless the USB stick is set up as EFI bootable. and then you're in a whole other world of pain
(16:34:05) clumens: YOU ARE ENTERING A WORLD OF PAIN.
(16:34:09) wwoods: thanks for that, apple
(16:34:42) bernie: wwoods, jeremy: oh, I see
(16:34:45) skvidal: wwoods: didn't you get the pointy stick with your apple?
(16:34:56) skvidal: wwoods: the one they ship w/the laptops so you can jab yourself in the eye
(16:37:04) bernie: wwoods: there's no easy way to build a bootable EFI USB stick with Fedora on it?
(16:37:15) wwoods: bernie: none that I know of
(16:37:24) wwoods: there might be a *hard* way
(16:37:33) bernie: not even with bootcamp?
(16:37:52) jeremy: livecd-iso-to-disk has a --mactel/--efi switch which works on many. but then you get into efi + modesetting failures in a lot of cases
(16:37:57) bernie: it makes XP boot, doesn't it mean that it fakes a PC BIOS?
(16:38:05) jeremy: bernie: all that bootcamp does is partitioning
(16:38:26) jeremy: bernie: when bootcamp was originally released, they also included a firmware update which does a fake bios. that works for cd booting, but their bios doesn't support usb booting
(16:38:42) mjg59: And also doesn't have that support on the Xserve
(16:38:49) bernie: jeremy: I see... apple is great
(16:39:02) mjg59: They implmented what they needed
(16:39:14) skvidal: bernie: keep drinking that kool-aid :)
(16:39:22) pjones: well, a CSM. which isn't necessarily a "fake" bios, but still.
