Hello everyone, I have a problem. I’m trying to install Zorin OS 18 on my Acer Extensa 215-22. I downloaded the latest version of Zorin OS 18 (Zorin-OS-18-Core-64-bit-r3), then Rufus on my computer. With my empty 8GB USB drive, I selected the USB drive and chose (Zorin-OS-18-Core-64-bit-r3) in GPT mode since I’m currently on Windows 11.
Then I disabled “Enable Fast Startup” in the Control Panel in Windows 11. I went into the BIOS by holding down Shift and then restarting the computer. After that, I disabled Secure Boot.
Next, I launched Zorin OS 18 from my USB drive. I reach the setup menu and it says “Check finished: no errors found,” but then nothing happens — the screen freezes with the Acer logo and the Zorin logo. Even after waiting 10–15 minutes, nothing changes.
I completely reset my computer and tried again, but it’s the same issue. If anyone has any ideas to help me, please let me know.
PS : I don’t have (HDD0 → EFI → ubuntu → shimx64.efi. Select shimx64.efi and confirm by pressing Yes).
For me, it’s HDD1 → EFI → (there is no “ubuntu” folder), but there are some other folders.
Did You checked that Your BIOS is in UEFI Mode? Did You checked the Checksum of the downloaded ISO? How is Your USB Stick formatted. Is Fast Boot and TPM in BIOS disabled, too?
Another thing you might check, which has been run into a few times here and there, is unplug everything you possibly can while you're testing this. Every once in a while something that you might have plugged in (even an external mouse) could cause some boot issues. I'd also make sure you're not plugged in to any external monitors and strictly use the built in screen (as I believe this is a laptop from a quick google).
What boot options do you see when you're selecting something to boot from the bios screen? I see you say you don't see an "ubuntu" folder?
In the System Information window (opened with Windows + R then msinfo32), under System Summary, the BIOS Mode is correctly shown as UEFI. In the BIOS (accessed by holding Shift + Restart), under the Boot section, Boot Mode is set to UEFI. The USB stick properties show FAT32 file system. The bootable drive was created with Rufus 4.13 (rufus-4.13.exe) using the ISO Zorin-OS-18-Core-64-bit-r3, which has a size of 3,699,168 KB in my Downloads folder. The partition scheme is GPT and the target system is UEFI (non CSM). The SHA256 hash of the ISO file matches perfectly: 09959CE793B8A065B70207E46CD646B1DE805FC7E0BAD925CE28DF6E04B7F807 (verified in PowerShell with certutil -hashfile "C:\Users...\Zorin-OS-18-Core-64-bit-r3.iso" SHA256). I have also disabled Fast Boot and TPM in the BIOS (Security → TPM (TMC) State set to Disabled).
Thanks in advance for your replies. I’m really fed up with all these bugs and I’m paying very close attention to every single one of your answers and pieces of advice.
I wonder about graphics, since you are seeing only a blank screen.
What GPU are you using?
AMD Radeon(TM) Vega 8 Graphics
EDIT : same bug on linuxmint-22.3-cinnamon-64bit
I would be curious to see if using Ventoy would be better. Last year I replaced Windows 10 with LMDE 7 on a client's Acer Notebook. Vntoy comes with MOK, and I had to enrol the EFI from USB in order to install Linux Mint Debian Edition. I would also then make sure when you boot into the BIOS in respect of boot order that you choose the displayed name of your usb device which has EFI at the end of it.
