I having trouble with installation of Fedora and/or Centos.

On first steps of installation, on step What type of devices will your installation involve, whatever I choose, same thing happen: I get window with message

An unhandled exception has occurred. This is most likely a bug. Please save a copy of the detailed exception and file a bug report.

In Details window there are lots of messages. At the end there are:

ERR kernel:[ 81.854179] device-mapper: table: 253:1: raid45: unknown target type WARNING kernel:[ 81.854183] device-mapper: ioctl: error adding target to table

Same thing occur with several versions of Fedora (17 and 16, x64, live, etc) and with Centos distribution also.

Can you please give me some advices how to avoid this messages? Thank you in advance!


It's Intel Xeon CPU, E31220 @ 3.10GHz.

In BIOS, ACHI Capable SATA Controller is defined in RAID Mode.

RAID Mode Options are defined as Intel(R) ESRT2 (LSI*). Tried also as Intel(R) RST, but always the same error occurred.

Perhaps you should change the configuration from AHCI to IDE.


Can you give some more info on the hardware you use?
