[SOLVED] cannot boot ubuntu from live usb

zoelee4 · 09-23-2016, 06:40 PM

I cannot boot into my ubuntu live usb from my razer blade (2016) I get the error message:

Code:

unable to mount root fs on unknown-block(0,0)

which I think is a driver problem with the kernel. however I don't really know and I have no idea how to fix it. I am trying with ubuntu 15 at the moment, but I have tried with 16 and 14 and always get the same error. also I really don't care what distro it is as long as I can boot from a live usb. thanks!

I assume it has to do with how the boot sequence is viewing the order of drives.

How do you boot to this usb? Do you move it above hard drive in bios hard drive order or do you select a usb boot option?

This means kernel has no driver for your HDD controller. Or, in case of EFI stub boot this means root=<root device here> was not passed to the kernel.

I select they drive by holding f12 at boot to get a drive list.

I tried it with a new usb and it now says: https://mail.google.com/mail/u/0/?ui...5760-local0&zw

It looks like Asus has changed the firmware key map. I have owned several Asus MBs, and they always used F8 to select the boot medium. So is F8 inactive?

Booting an external medium from a UEFI computer is different. They usually have two boot modes, standard and legacy. If you provide more information on how you created the live usb, maybe it will ring a bell with some of the posters here.

f8 also works, I just use f12 because it is also how you select your boot device. I have found where the legacy options are and I turned them off. then I tried with gentoo. it worked, so I guess that is fixed. ubuntu still does not work, but that is OK.
