Bug Description
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/
- see BootInfo summary created via Boot-Repair: http://
- Ubuntu contains /boot/grub/grub.cfg , but no core.img and no grub.efi
- MBR has not be modified (it contains no GRUB)
WORKAROUND: purge and reinstall grub-pc via Boot-Repair, with nomodeset option, allowed to obtain GRUB menu with access to Ubuntu and Windows. See resulting BootInfo: http://
That means Ubiquity should not try to install grub-efi on this system, but grub-pc (+nomodeset) instead.
