Author: ekohl Date: Thu May 22 14:55:04 2014 New Revision: 63411
URL: http://svn.reactos.org/svn/reactos?rev=63411&view=rev Log: [USETUP] - Fix a failed partition type assignment, when unpartitioned disk space is converted to an extended partition. - Rename the extended partition list to logical partition list. - Add a pointer to an extended partition to the disk entries. And keep it up-to-date when the primary partition list is built or modified. - Add the 'Unpartitioned space' partiton entry to the logical partition list when an extended partition has been created. - Remove all logical partition entries when the coresponding extended partition will be deleted.
