Public bug reported:

Initial situation: HP Touchsmart 520, 64bit 4GB, pre-installed Windows7
(on sda1 and sda2), non-GPT disk, 356Go unpartitionned space after
Windows.

Installed Ubuntu 11.10 via automatic installer. Ubiquity gave no errors
nor warnings during install.

After install: 
- after reboot, no access to Ubuntu. PC boots directly to Windows.
- see attached files: /var/log/installer/syslog  ,  /var/log/installer/partman  and debug files,
- see BootInfo summary created via Boot-Repair: http://paste.ubuntu.com/890361  (apparently boot is in EFI mode)
- Ubuntu contains /boot/grub/grub.cfg , but no core.img and no grub.efi
- MBR has not be modified (it contains no GRUB)

** Affects: ubiquity (Ubuntu)
     Importance: Undecided
         Status: New
