Здравей,
Ето част от текста за инсталиране на Grub:
...BEGIN...
The most critical part of understanding GRUB is getting comfortable with how GRUB refers to hard drives and partitions. Your Linux partition /dev/hda1 will most likely be called (hd0,0) under GRUB. Notice the parenthesis around the hd0,0 - they are required.
Hard drives count from zero rather than "a" and partitions start at zero rather than one. Be aware too that with the hd devices, only hard drives are counted, not atapi-ide devices such as cdrom players and burners. Also, the same construct is used with SCSI drives. (Normally they get higher numbers than IDE drives except when the BIOS is configured to boot from SCSI devices.) When you ask the BIOS to boot from a different hard disk (for instance your primary slave), that harddisk is seen as hd0.
Assuming you have a hard drive on /dev/hda, a cdrom player on /dev/hdb, a burner on /dev/hdc, a second hard drive on /dev/hdd and no SCSI hard drive, /dev/hdd7 gets translated to (hd1,6). It might sound tricky and tricky it is indeed, but as we will see, GRUB offers a tab completion mechanism that comes handy for those of you having a lot of hard drives and partitions and who are a little lost in the GRUB numbering scheme.
Having gotten the feel for that, it is time to install GRUB.

Но тук реалният проблем е LVM-а.
От предния пост разбирам, че sda1 е /boot (100MB) а sda2 е LVM със всички останали дялове (вкл. root) вътре.
При мен /boot и /root са на отделни дялове а останалите са в LVM2 контейнер. Но не е FC5 (въобще не е Fedora, Gentoo).
Предполагам, че FC5 има/използва initrd в което е вграден и LVM, но каква точно е конфигурацията, нямам представа.
Питай и в ML на Fedora, все някой трябва да знае.
Иначе имаше едно Howto за LVM със /root дяла вътре, потърси в
http://www.gentoo-wiki.com. Това обаче е относително специфично за Gentoo, но може да даде някои насоки.
