I've tried installing Mint 13 KDE 64 bit via DVD and via USB stick. I've also verified the MD5 on the iso file. I've burned multiple DVDs (on multiple drives and computers) and USBs, downloaded from multiple mirrors, etc. I've tried installing to multiple hard disks on two very different machines (1 personally made reasonably high end desktop machine, and one fairly new Dell laptop.) The desktop has 8 gigs of RAM and and a quad core Intel CPU. The laptop has 4 gigs of RAM and a pseudo-quad cure Intel CPU (dual core with hyperthreading.) Smallest disk I tried was a new Samsung 830 120 gig SSD. Others were true hard disks with the smallest being 160 gigs. I'm using the full disks for the install. In all cases, I get the following results:
1.) Live CD boots and runs fine.
2.) If I try to install, using any permutation I can think of on partition selection, including manual and EXT3, versus EXT4, series formating, the installer crashes during the format process (disk prepare showing 33%.) It gets a little further (to the enter user/computer names, but still showing disk prepare at 33% with EXT3.
3.) Same results if I boot into compatibility mode.
4.) If I interrupt the boot to live CD and do an integrity test, I always get "1 file failed," but no definition of what file. Again, from multiple DVD burns, multiple downloads from mirrors, multiple USB sticks, all with the ISO MD5 verified.
5.) Since I'm in live CD (I assume to be the reason), I can't update the installer or run the package managers/updater. All crash with various forms of IO error, or can't update files.
6.) I've successfully installed current KUbuntu and Mint 13 Mate on these same machines.
7.) I've run extensive Memtests and disk verifies on both machines and all physical disks I've tried.
8.) In no case am I trying to multi-boot. I'm physically putting in a new drive, and removing "old" system drives.
9.) About the only thing I haven't tried is installing an older version of Mint KDE and upgrading. I really prefer clean installs.
I'm a somewhat experienced Linux user (multiple distros for about 5 years) and a very experienced Windows user (considered a geek by some), but not a Linux guru. I'm at a loss. I prefer the KDE desktop, but prefer Mint to Kubuntu. I've seached Google and Mint forums on this, but haven't found anything that helps. I'd really like to get this install working, but have run out of ideas.
