I just installed Fedora 18 alongside a pre-existing windows 7 from a live-usb to a single 1TB hard disk with multiple partitions.
created all necessary partitions as recommended:
/ :40GB /boot :200MB /home :350GB
BIOS BOOT of 1MB
The setup ended with a successful installation message but when I rebooted the GRUB didn't load. In fact the BIOS didn't show HDD in the boot order.
When I again booted using live-usb I saw that all the partitions were existing.
I tried reinstalling; the setup detected previous installation. I reinstalled with same partition sizes but again the boot failed.
I had read, recently, about installing Ubuntu in EFI mode, which specifies that:
- There needs to be a EFI boot partition (Optional: with mount label /boot_efi).
- It needs to be in the starting of the disk and should be FAT32
A windows EFI boot partition already exists. I thought I shouldnt mess up with this and created a separate BIOS BOOT partition for linux. I was not sure how to assign this as a EFI type partition. When I continued with the installation I saw that grub was installed and updated too. But again linux failed to boot.
