I am at my wits end with this computer. I bought and Acer Aspire 4752 with a fully loaded version of Windows 7 on it. I prefer Ubuntu so I began to install 14.04 from USB.
Got the error: [Errno 5] Input/output error
This is often due to a faulty CD/DVD disk or drive, or a faulty hard disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers), to check whether the hard disk is old and in need of replacement, or to move the system to a cooler environment.
So I tried a different USB stick, same error. Tried different versions of Ubuntu, got the same error. I've used startup disk creator and Unetbootin to make start USB boot devices.
I can boot with the USB drive and run Ubuntu that way. I even checked the hard drive using the tools in Ubuntu. Everything was fine, except it said the hard drive was hot. I tried a different hard drive. Got same error above. I ran a test with mem86, everything was fine. No matter what I do, using the USB gives me the Errno5 error.
I then switched to using DVDs. Now I keep getting an uncompression error when installing Ubuntu 14.04 or 12.04.
I can't figure out for the life of me why I get nothing but errors. Can anyone help?
