UEFI & Ubuntu netinstall crashing - AdrianSt - 2014-09-12 10:45

Hi there,

I've tried launching Ubuntu's netinstall (precise/amd64) through iPXE and UEFI.
Sadly it crashes saying it cannot find the root block device.
Disabling UEFI and using BIOS it launches just fine.
The same happens with Fedora's netinstall.

Code:

VFS: cannot open root device "(null)" or unknown-block(0,0): error -6

I used these settings:

Code:

:ubuntu-trusty-amd64

initrd http://de.archive.ubuntu.com/ubuntu/dists/trusty/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/initrd.gz

chain http://de.archive.ubuntu.com/ubuntu/dists/trusty/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/linux fb=false

boot || goto failed

goto start

:install_fedora

initrd http://ftp.uni-kl.de/pub/linux/fedora/linux/releases/20/Fedora/x86_64/os/images/pxeboot/initrd.img

chain http://ftp.uni-kl.de/pub/linux/fedora/linux/releases/20/Fedora/x86_64/os/images/pxeboot/vmlinuz inst.repo=http://ftp.uni-kl.de/pub/linux/fedora/linux/releases/20/Fedora/x86_64/os/

boot || goto failed

goto start

Under UEFI, kernels (currently) need to be told the name of the initrd file. Try adding "initrd=initrd.gz" to the Ubuntu kernel command line, and "initrd=initrd.img" to the Fedora kernel command line.

Thanks, that did the trick.

By the way, wimboot is awesome. Thanks to your brilliant work I can now operate a hybrid UEFI/iPXE Server without relying on Microsoft's horrible WDS PXE implementation for Windows rollout.
