I recently got a new computer and I have been trying to get a dual boot Windows/Ubuntu to work, so I got Ubuntu on a USB key( using Rufus as recommended in the Ubuntu page) but when I try to boot from the USB key and select Try Ubuntu without installing, I get the following error (and some variations of it)
Couldn't get size: 0x8000000000000e BusyBox v1.27.2 (ubuntu 1:1.27.2-2ubuntu3.2) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) mount: mounting /cow on /root failed: invalid argument overlay mount failed
I have tried with to different usb keys, and also disabling secure boot and fast boot.
After trying with nomodeset as recommended by sudodus, I get the following:
[ 9.028870] Couldn't get size: 0x8000000000000e [ 13.311279] overlayfs: unrecognized mount option "lowerdir=" or missing value BusyBox v1.27.2 (ubuntu 1:1.27.2-2ubuntu3.2) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) mount: mounting /cow on /root failed: invalid argument overlay mount failed
I also have seen so post where people with a similar problem solved it by installing the appropriate GPU driver, but in that case the problem was after installing and rebooting, in my case I don't even get to install (or try it). Some info about the computer in case is relevant:
Asus FX505GD_FX505GD Intel i5-8300H 2.30Ghz Nvidia GeForce GTX 1050 4GB
The original OS was Microsoft Windows 10 Home
I'm happy to provide any other information, but I don't know what to look at.
Update: Following the answer of Akeo, I remove the persistence from the USB key and finally I manage to get into the try version of Ubuntu, but another problem appeared when I turned off Ubuntu ( from the try version, It was a bit late so I decided to install it later the next day). It took a long while ( about 3 min.) for the desktop to disappear (in the mean time it was frozen). When if finally disappeared I found this message(which again contains the
Couldn't get size error):
and it continues:
This makes me worried about installing it from this USB key.
