Cannot load Linux Mint 17.1 Rebecca on Lenovo 7220

[Don Oliver]

I am trying to install Mint 17.1 Rebecca 64 Bit on Lenovo ThinkCentre Model 7220 with Intel Dual Core 3.0Ghz. The disk will start to be read then a message appears on screen saying :No Emulation System Type -80". The disk stops being read and the PC reboots and goes through the same cycle again. I was able to install the 32 bit version but had to use the 2nd option on menu to force the installation. I looked for this same option on the 64 bit version menu but do not see it. Tried the "compatability mode" but that didn't work either.

2nd question - I already have 32 bit going on the Lenovo. Is there a way to upgrade to 64 bit without going through the iso disk method?

Unless you have way more than 4 Gb of RAM, I suggest you stick with what works . .

That may be the best option although I do have 8Gb of RAM

You cannot turn a 32-bit installation into a 64-bit installation by some kind of "upgrade process". If you want to turn the existing Mint 17 32-bit installation into a Mint 17 64-bit installation, this will be a fresh installation from scratch.
