Installing crashes halfway through "Copying Files," showing an I/O device error error number 5.
There was problem in beginning of installation too--Ubuntu was not detecting the installed Windows 8 system.
My system is a dell Inspiron 5520 laptop, with a 1 TB WDC hard disk in GPT, with EFI.
My current partition layout is:
102 MB EFI SYSTEM partition
200 GB Windows 8 ntfs
22 GB root Ext4
8 GB swap
20 GB home Ext4
680 GB ntfs Drive for storing all my files
I tried installing both from a DVD disc and a USB drive; both resulted in the same error.
The built-in Dell hardware diagnosis utility showed both hard disk and DVD drive as healthy.
What may be the reason and how can I install ubuntu along side my Windows 8 system?
