Ubuntu trial on bootable usb mode works fine, but after doing full installation and then removing the USB as i was instructed to, I get the following error after being stuck in loading screen after choosing Ubuntu in grub :
end kernel panic - not syncing: VFS: unable to mount root fs pn unknown block (0,0)"
I am using msi laptop with Nvidia drivers.
Do you have dual boot? Do you have grub installed? have you tried booting another kernel version? or safe mode?
have you tried using google?
Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
I would say this is similar, but an older version of your question.
the mentioned topic should help you, but some CLI experience might be handy.
Actually I had the same issue and I have not identified the solution yet, I may have found the work around for that.I installed ubuntu in a dual boot configuration from a bootable USB stick which I have created using GPT partition scheme. I got the above error. Then I tried to create a bootable USB drive using MBR partition scheme and tried to install it now.I was able to install and boot it without any error in legacy mode.In my laptop,Windows uses UEFI mode and Ubuntu uses legacy boot mode. Although this may not be a perfect solution to your question, this can be a nice workaround for someone like me who cannot boot using UEFI.
First, you can try this :
The boot from livecd option and try using the terminal to fix your installation. Instructions in this link : https://askubuntu.com/a/48516/395498
although this is for an older version, i think if it was me, i would give it a go, just because the installation is already broken, this might fix it.
if this fails, or produces more faults, have you tried reinstalling? since you already deleted the entire harddrive, this might be your quickest option. i first would try to repair it using the topic provided, you can copy the link to a usb drive, when booted from live cd you can copy and past the link into your browser.
