Hi guys,

I'm falling at the first hurdle a bit here. I've used dd to put the latest minimal .iso onto a usb stick however, when I boot into the environment I get stuck when the kernel looks for the rootfs and the cdrom.
I've tried various methods on the forums to get around this

1. rootdelay=10
2. slowusb
3. scandelay

nothing seems to force the kernal to see /dev/sdb. When looking for rootfs I did offer up "/dev/sda3" where my current rootfs is and it booted my computer back into Ubuntu but when offering "/dev/sdb1" or "/dev/sdb" it says "Not valid rootfs.

Any advice before I just go out tomorrow and buy some CD's? I'd rather get cracking tonight in all honesty

Is your bios set to/capable of booting from usb?
Is the usb boot defined as the first boot device?
Legacy bios or efi? etc.. etc.. But more importantly:
Are you absolutely sure you want to do this with the minimal-iso it's-very-minimal.
If you just want to boot an install environment systemrescuecd is a preferred option, it's gentoo under the hood, with a heap of useful tools, and great install instructions. You can follow the handbook install without change. It's almost the defacto default around here.

Might save you from buying some cd's anyway.

Cheers

Best install media:

Best usb install procedure:

Takes a bit more than dd a minimal iso on to a usb to get a bootable usb

Or why not install from ubuntu?

Hi Guys,

I used the SystemRescueCD method and it worked perfectly.
I have a working Henrik installed now, marking as Solved.

Thank you
