Bug#733049: debian-installer does NOT add bootable flag in guided partitioning mode

[Andres Cimmarusti <acimmarusti@gmail.com>]

Package: debian-installer
Version: 20130613+deb7u1+b1
Severity: normal
Tags: d-i

Since version 7.0 of wheezy, the debian installer has had this problem. 
The debian installer in guided partitioning mode does NOT automatically 
add the bootable flag to the appropriate partition. This can result in 
unbootable systems, especially for beginners.

This should be corrected in wheezy and beyond.
