Any idea how to install gentoo on a bootable USB external HD?
I can not boot anyway.
Here is what i did

build a 32bit gentoo on my USB /dev/sda4
use genkernel to build a kernel on /dev/sdb2

it stopped at booting, and jump into Boot()::, I have no idea why.
Please help me

Did you actually finish installing?

If so do you use GRUB or LILO? Please post their configuration files.

my problem is caused by the initrd created by genkernel, there is no /dev/sdb* block devices.
I tried to mount that initrd, but it outputs the following errors:

I have gentoo (2.6.11-gentoo-r3) on an external USB drive. Grub on the MBR of the external drive.
It works fine .

for the "unrecognized block device sdb", try to put 'udev' in your kernel line.

But first of all, show your partitioning scheme, your /etc/fstab and your grub.conf

Oops, forgot this: :lol:

your mount seems to complain:

sudo mount -o loop /mnt/gentoo32/tmp/initramfs-genkernel-x86-2.6.12-gentoo-r9 /mnt/loop
ioctl: LOOP_CLR_FD: Device or resource busy
mount: you must specify the filesystem type

You can try:

sudo mount -t cramfs -o loop /mnt/gentoo32/tmp/initramfs-genkernel-x86-2.6.12-gentoo-r9 /mnt/loop
