You received this bug
there is now a tool called USB startup disk creator available in
ubuntu that automates all the needed work here; and it works perfectly
fine. I tried using the UNETBOOTIN approach, but it produced a version
which ran into many of the problems listed above by Jan. This was with
the latest ubuntu
I have tried both jaunty-alpha6 alternate x86 and intrepid alternate x86
images.
usb-creator (intrepid deb installed on hardy) made a stick that said no
operating system
or operating system errors on a dell optiplex 760. unetbootin made a stick
that booted.
Both jaunty and intrepid ISOs have
Symlinks (/dev/cdroms/cdrom0 - /dev/sde1) does not work on
vfat.
I have extracted iso-scan.postinst and put it in the top of the usb stick
to run manually. Doing so gives modprobe error module loop not found.
I commented out that line and ran the rest immediately after , but the
debootstrap
OK,
I got further with solving the problem, it seems to work now.
Steps I did:
- make a vfat -F 16 onto the USB stick
- syslinux -sf /dev/sdx1 (sdx = USB stick)
- copy the contents of the alternate CD to the stick as close as possible,
including the hidden .disk directory
(I used tar)
-
OK, it works that way:
USB stick needs two partitions.
first is a small vfat with copies of the boot files from the CDROM
(isolinux, install,.., but not the dists). copy install/isolinux.cfg to
syslinux.cfg and run syslinux.cfg
second partition is = 720 MB. copy the CDROM blockwise (dd ...)
