Hi Wen,

I'm still no further along with this install. I have tried again today with the KXstudio live disc, and for whatever reason the ssd is now no longer being recognized from the live disc and from Win7. The instructions listed in the links you sent I had pretty much already followed as I had used this guide http://www.linuxbsdos.com/2012/07/23/dual-boot-ubuntu-12-04-and-windows-7-on-a-computer-with-2-hard-drives/2/ . I checked my bios and made sure i selected ahci where it was applicable but this did not fix anything. I have to say i am out of ideas (and motivation) here and will need some help if you are able to spare some time. Many thanks.

Justin

Unless you're dual-booting, *always* set your SATA controllers to AHCI.
The options "legacy", "hybrid" and "PATA" are worse choices for Linux.

Erratum: current hardware seems to add NVMe, which appears to be better?

The default should be relatime (check /proc/mounts),
which should be near enough.

Changing it to noatime will break a handful of programs,
but you probably don't use them anyway.
