Cannot install OS 5.1 - fails with errno 5 "Input/ouput"

Question

I've been trying to install elementary OS 5.1 for the past couple of hours with no luck. The installer keeps failing 2/3rds of the way with the following error message:

The installer encountered an error copying files to the hard disk:
[Errno 5] Input/output error

I'm trying to install elementary OS from a USB stick onto a fresh hard disk (bought the SSD today).

My system

• Intel i5
• 8GB ram
• GTX 650 TI
• the fresh 120GB SSD (previously working components). ISO filename: elementaryos-5.1-stable.20191202.iso

What have I tried to do:

• I've tried to burn the latest ISO using both Etcher and Rufus, but with no luck. I've tried both ISO and DD versions in Rufus - no difference.
• I've checked the hash, which matches up with the hash on the installation guide page.
• I've tried to set up custom partitions when running the installer - tried both ext4 and ext3 partition settings.
• I've tried to select the "Try elementary OS" option, and then running the installer from terminal with ubiquity

I am honestly at a loss of what to try at this point...

Please help :)

thanks in advance.

Solution

I had the same issue with Elementary 5.1(Hera) and tried the following things.

• Downloading the iso again
• Did hash check and found it's ok
• Recreate the USB using Unetbootin, then Startup disk creator
• ubiquity --no-migration-assistant
• Restructuring partitions

But none of the above worked.

Finaly what worked was, i wrote the image to a DVD using Brasero and tried. It worked like charm.

I know it's wierd, but that simply worked. I have read this solution in other forums too.
