Debian Installer can't see my partition table

[Conrad Nelson <yaro@marupa.net>]

Hello Debian Mailing List,

I am trying to go back from Debian Sid to Jessie or Wheezy, but when I 
run the installer (Latest Wheezy netinst disk image.) and go into manual 
partitioning, it does not see any of the partitions on my primary hard 
drive.

fdisk sees them with no issue:

/dev/sda1   *        2048    35653631    17825792    7 HPFS/NTFS/exFAT
/dev/sda2        35653632    35858431      102400    7 HPFS/NTFS/exFAT
/dev/sda3        35858432   861427696   412784632+   7 HPFS/NTFS/exFAT
/dev/sda4       861427728   976784129    57678201    f  W95 Ext'd (LBA)
/dev/sda5       861429760   861818879      194560   83  Linux
/dev/sda6       861820928   966774783    52476928   83  Linux
/dev/sda7       966779370   976773145     4996888   82  Linux swap / Solaris

How can I get my partitions known in the installer?

Thanks,

Conrad
