"input/output error during read on /dev/sda" during installation [closed]

Solution 1:

From your description, it sounds like your disk is dying. To confirm this, I suggest using a low-level disk integrity checking tool, like Salvation HDD Scan and Repair

Formatting the disk will only resolve problems at the filesystem level. If the aforementioned tool detects any errors, your only recourse will be to replace the disk.

Solution 2:

I have experienced this problem because of bad installation media. Download from torrent or check the MD5 sums against the ones here.

Solution 3:

I had this problem too; I fixed it by changing the HDD to SATA mode in BIOS.
