Getting Namespace lookup failure while installing LL 4.0

Please post the error message here
(there are many different namespaces)

I've now added the screenshot

[kpanic]

So, when does this happen? While installing (the screenshot does not support that) or after the installation?
Can you boot the installation CD / USB ?

[Asif Ansari]

This is while installing, Yes I can boot from the pen drive and right when I select "start linux lite" option it gives me this error

[kpanic]

Ok, try this:

When you get the Menu, press 'e' to edit the boot parameters.

Then find the row which begins with the word 'linux'. Then navigate (using the arrow keys) to
go to that line. Then press End key to go to the end of that line or navigate there using the arrow keys.

Finally append the text 'acpi=off' to the end of the line and press Ctrl+x to boot

[Asif Ansari]

No I do not get the grub option, so there's no "press e to edit" option, it's right after booting from the installation media (Pen Drive)
I tried to press "tab to edit" and add acpi=off to that line.still the same issue

[kpanic]

Oh yes, this GRUB version seems to be different - it is the TAB key instead of 'e'.

Can you disable ACPI (Advanced Configuration and Power) from BIOS?

[Asif Ansari]

No option to disable acpi in BIOS

[kpanic]

When you add the boot parameter acpi=off you must be very careful.
The text must be in the same line where the 'linux' entry is. And you must have exactly ONE space between the last
character and the text acpi=off

Also, there must not be anything else after the acpi=off text - not even a space character.

Example:

Code:

linux /boot/vmlinuz.... bla bla bla quiet splash acpi=off
