I have a cheap laptop: ASUS E403S Laptop - Intel Pentium CPU 2GB RAM 32GB eMMC Storage 14" Screen Windows 10 … I think it was upgraded to Win11 before trying this Zorin installation. So, I installed Zorin 15.3 Core (“Zorin-OS-15.3-Core-64-bit.iso”) on this machine, from a USB. Before that the machine was performing very slowly (=poorly). The installation went normally, without problems. And there were no visible errors to mention during the process.
BUT after installation (after re-boot) I got into very bad glitch/Catch-22 dilemma! When starting the laptop again it doesn’t recognize anything on the USB and the only other thing it does is it comes into a menu that has three choices:
- Advanced options for Zorin
- System setup
On the bottom of the screen it has three keyboard options, but they are basically the same as those three listed choices too. And there is a timer bar on top of the screen … advancing… if you do not choose anything it will choose number one of those choices (starting Zorin) .
If I choose number one all I get is this:
error: /boot/ vmlinuz – 5.4.0-96-generic has invalid signature
errorr: you need to load the kernel first.
Press any key to continue...
And I get nowhere from this message…. Since it brings me back to the original 3-listing
If I choose number two all I get is this:
Zorin, with Linux 5.4.0-96-generic
Zorin, with Linux 5.4.0-96-generic (recovery mode)
Zorin, with Linux 5.4.0-47-generic
Zorin, with Linux 5.4.0-47-generic (recovery mode)
When choosing any of these lines I get the same message as in first case (with the exception of those “96” -→”47” changes in text.
The third option takes me to the Asus BIOS (American Megatrends, version 213, GOP version 8.0.1033) … where I can only choose now the “ubuntu” as my boot preferences.
I AM STUCK! Can you help….. please.
One more thing: Anything else I seem to able to do at startup is to hit ESC while starting... and then it takes me into GNU GRUB version 2.02 view with some text and then the command line saying “grub>”. Since I am noobie in the Asus I am at loss.
This laptop does not have possibility to just remove the hard drive since it is welded I guess on the motherboard.
How can I get the computer back somehow so I can re-install Zorin (any other version) or any other Linux distro???
