Ok, it must be something else then. Usually, when there is a problem 
with disklabel, a standard recommendation is to zero out the first few 
megabytes of the disks and then write a brand new disklabel to make 
sure that everything is ok (warning: this will irrecoverably destroy 
all data on the disks!). It goes something like this:

1. Boot the installer as usual.
2. Proceed to the point where the disks are detected and partitioner 
is started.
3. Press 'Back' button until you get to installer menu.
4. Choose an option to start a shell.
5. Run the following commands:

dd if=/dev/zero of=/dev/sda bs=1M count=100
dd if=/dev/zero of=/dev/sdb bs=1M count=100

6. Exit the shell and restart the partitioner.
7. Choose the guided partitioning, it should write a new disklabel and 
create the partitions.
8. Continue installation as usual.
