Comment 0 for bug 259540

I started the Ubuntu 8.04.1 amd64 CD in Windows and selected "Install inside Windows" option.
Then in the "Ubuntu Setup" dialog I left the default options (which were : "C:", "15", "Ubuntu", "English" and "administrator") , entered a password (twice of course) and clicked "Install".

After some copying it rebooted.
In the Boot menu I choose "Ubuntu". For a few seconds it displayed a warning*, then started loading.

After the desktop was loaded, an error dialog appeared, saying:

No root file system is defined.

Please correct this from the partitioning menu.

(see screenshot)

After clicking OK, the same dialog reappears. (many times)
So the installation is stuck at this point.

The existing OS is Windows 2008 Datacenter x64.
The harddrive is a Dynamic Disc, having one NTFS partition (C:).

* - the warning is :
Warning: Unrecognized Partition Table for Drive 80. Please rebuild it using
a Microsoft-compatible FDISK tool(err=114). Current C/H/S=16383/31/63
Press 'ESC' to enter the menu...

Feel free to ask for any other information.
