When you see "Boot device didn't show up after " in USB booting again

This is an old problem with our new iso: Boot device didn't show up after 30 seconds...

It sprung again when I try booting from USB using our recently release 2010.05.iso. This time something different happens. I mean you can not solve the problem by the method mentioned in this thread (http://bbs.archlinux.org/viewtopic.php?id=77815). You can not because when you are thrown into the ramfs shell, and issue an `ls /dev/sd*', you won't find the node /dev/sdb1, but only /dev/sdb! Don't do `ln -s /dev/sdb /dev/disk/by-label/ARCH_201005', it won't help. What you need to do is unplug your USB and replug in. And then you will find the node /dev/sdb1 which is linked to by /dev/disk/by-label/ARCH_201005.

Is it a bug?

EDIT:

It is not. I later found the file system in my USB is NTFS, which is surprising because I remember it was once formatted to ext2. So I reformat it to ext2 and everything works flawlessly,

This happened to me when I made the bootable usb key with unetbootin.

Then I tried with isohybrid and dd: it worked just fine.

Which image is it, and how did you transfer it to USB? Did you try with another computer? netinstall x86_64 is booting up just fine for me.

I used the i686 iso, dd to USB. I tried with another comp, the same.

Re: When you see "Boot device didn't show up after " in USB booting again

I passed through similar situation, my environment is as follows:

To prepare a USB disk under Windows XP SP3
Using archlinux-2010.05-netinstall-dual.iso
    (I also tried and bump into the same error messages on archlinux-2010.05-netinstall-i686.iso)

The USB Label is originally named MULTIBOOT (which should be modified to overcome the problem without manually perform
    ramfs$ ln -sf /dev/sd[x] /dev/archiso
    ramfs$ mount -t vfat /dev/archiso /bootmnt
  post by tiny.ian in the thread http://bbs.archlinux.org/viewtopic.php?id=77815 )

The format of my USB disk is FAT32

I use syslinux 3.86 under WinXP SP3 to prepare the USB disk by
syslinux -ma -f F:
while F: is my USB disk ID show in WinXP SP3

After that, I also use WinCDEmu to open the "archlinux-2010.05-netinstall-dual.iso"
and copy all files in the newly mounted iso file into my USB disk.

Enter into my USB disk,
Change Directory to boot
and modify the "isolinux" directory into "syslinux"

Change Directory to boot\syslinux
Rename two files
isolinux.bin -> syslinux.bin
isolinux.cfg -> syslinux.cfg

To overcome the difficulities, open syslinux.cfg by text editor (I use notepad++)
search ARCH_201005 and replace it by ARCH2KT5
(2KT5 is named after 2Kilo, Ten and Five, which make the label ARCH_201005 no longer than 8 characters. I agree with cwjiof's post, and I guess any string whose length falls between 1 to 8 shall also work.)

RENAME my USB disk Label to ARCH2KT5.

Reboot using the USB disk and my problem was solved just as the thread mentioned (http://bbs.archlinux.org/viewtopic.php?id=77815).

Hope this experience would be some help.
