Long story, short story. I have a Sony Vaio laptop, model SVF 1421S1E, which I use mainly for teaching purposes. Since I need both Windows and Linux I intended re-partitioning the 750GB drive to allow me to install Mint 18.2 alongside Win 8.1. Trying to generate a clone before i did the re-partitioning failed due to 'read errors'. SFC showed unfixable errors, it then failed the long Seagate generic test, so Chkdsk /r and another long test - failed.
This laptop now has a brand new 1TB drive in it, considering its expected use a ridiculous capacity. I installed 8.1 on it then reduced the size of the partition to give me ~300GB of space for Linux and installed Mint 18.2 from a USB stick into this partition. The installation has failed twice with the message that the Grub package did not install.
I am thinking of basically blanking this hard drive and returning it to one empty partition and starting again. But should I install Mint first or Windows ? Or is there a better way of going about this than starting all over again. Win 8.1 is working but I have no choice to get into Mint.
