I wanted to install elementary OS Hera, but failed numerous times. I get the "errno 5 input/output" error during installation. I searched through forums and what not and tried everything they mentioned:
1. Flashing ISO & DD both; 2. Checking for damaged sectors (none); 3. Using Ext4 & Ext3 both; 4. Installing directly and through "Try Elementary"; 5. Checking HASH in rufus (it's the same); 6. Tried the commands in the terminal (ubiquity --no-migration-assistant); 7. Testing RAM for problems (none); 8. Secure boot is off
Maybe the only thing I haven't tried is installing with a CD. I forgot to mention I am using a 1TB USB flash drive.
I have a laptop "Toshiba Satellite p50-c-169".
PS: NTFS file system + GPT partition
