He is saying to force the unmount using the provided commands in a terminal Opened on the LiveUSB.
So I have to boot in zorin os with pendrive and try that command?
Does it have terminal?
Yes, to both.
I use terminal with LiveUSB all the time.
I am starting to suspect a corrupted .iso burn.
Can you please (I know, this is very frustrating) re-download Zorin OS 16 from a Different Mirror, then use Unetbootin or Rufus to burn it to either a thoroughly wiped USB stick or a Different USb stick?
I thought all this was on Zorin OS 16 Core.
Are you installing Zorin OS 15.3 Lite?
Yes I'm gonna install lite version.
32bit or 64bit?
64bit it is...........
This usb stick is right cause my friend also used this and it was a success but since his system was based in mbr and mine was gpt so I created again.
A USB stick can go out at any time.
Ok well:
Either. Or xterm.
That is the Terminal Preferences dialog to configure the terminal, not the terminal itself.
You might try alt+F2 and xfce4-terminal
Strange, zorin now asks me a username and password
After I used that command.
on the LiveUSB, User: zorin
Password:
Password is just blank.
It's incorrect Nah I'm sorry I used capital z insteal of small one it worked
what should I do now?
Nvm, I'll try zorin core tomorrow for the very last time. If it works then no problem.
I don't know from where the problem is coming:-
I created unallocated space.
Also, disabled fast boot, fast startup boot, secure boot, hibernation mode.
Mode boot set to Uefi. Also Tpm disabled.
My disk was in Gpt style scheme So I created GPT style bootable pendrive with zorin os Lite. Still rip.
The problem appear is that something is using mount or my laptop is denying the access of it.
You may try sudo umount -l -r -f /cdrom
in terminal, but may need to perform grub repair after.
