Hello,
Thinking about the isntallation issues, I have 2 concerns: First one. What should be the size left over the 1st partition of the disk for the MBR? I may not have enough size. Is it documented?
Thank.

MBR is pre-reserved space at the front of the disk, before the first partition. AFAIK you can't put a partition there, so you've no need to worry about it.

I do not think so. If there is not enough room in front of the first partition, the MBR is not going to fit. I already had this glitch. For example: fdisk -l /dev/sda /dev/sda1 4096 6008309 3002107 82 Linux swap / Solaris gives enough room for the MBR, but
fdisk -l /dev/sdb /dev/sdb1 63 24981074 12490506 7 HPFS/NTFS/exFAT probably does not give me enough room to fit properly a MBR

this has NOTHING to to with the MBR it is GRUB2 which is bloated like a OS itself
For example: fdisk -l /dev/sda /dev/sda1 4096 6008309 3002107 82 Linux swap / Solaris gives enough room for the MBR, but
it gives you enough room for GRUB2 any modern partitioning tool starts the first partition at 2048
fdisk -l /dev/sdb /dev/sdb1 63 24981074 12490506 7 HPFS/NTFS/exFAT probably does not give me enough room to fit properly a MBR
is a partition scheme created many years go

I've still got some of these from dual boot installs transferred between discs (have experienced problems getting Windows to boot after changing the first sector to something sane in the past). I assume at some future point UEFI Grub is going to have problems with this, but still using BIOS for the moment.

I don't think so. http://en.wikipedia.org/wiki/Master_boot_record#Disk_partitioning tells us that the MBR is at the beginning of the physical drive, not in a partition. If you'll scroll down, you'll also see that the MBR is still only 512 bytes. Here's what fdisk -l has to say about the first partition on my main hard drive:
/dev/sdb1 * 63 83885759 41942848+ c W95 FAT32 (LBA)
I assure you, there's an MBR there because it's been there since before I installed (and switched to ) Linux.

the problem is that Patrick doe snot understand the differnece between MBR and the different grub-stages which has nothing to do with partitions at all

Yes, that is right, I am sorry for the confusion.
Hello,
Unfortunately, after I remade a new DVD, the issue is still here: Fatal error after installing 4 or 5 packages over 1318(hwdata or setup) Is there something wrong with this partitionning: / /boot /usr/lib64 /usr/local /usr/src /tmp /home ?
Thank.

Obviously needed.
/boot
Generally advised to have a separate boot partition.
/usr/lib64
I believe this will cause many issues. I'd advise against it.
/usr/local
Fedora doesn't put anything in here so should be fine.
/usr/src
Again not really used for Fedora so should be fine.
/tmp
In Fedora 18 'tmp' is a RAM backed file system, so you probably don't need this (unless you have other requirements). Probably a better use of a partition would be to put 'var' on it.
/home
Generally advised to have a separate home partition.
So you're mostly fine, with the exception of '/usr/lib64'.
Hope that helps, Thanks, Michael

no installer since years starts with the fist partition in a range you have to think about
