I want to install openSUSE on my new laptop. I partition my hard drive (600gb) with 5 parts:

c: 97gb d: 150gb e: 150gb f: 100gb g: 50gb and 38gb unallocated part

In the openSUSE installation, the yast makes a 2gb for swap 14gb = root , 21 gb = home, but in Installation Overview under Booting has a red error:

 the Boot loader Installed On a Partition that does not Lie Entirely Blew 128 GB .The system maight Not Boot;

What`s the meaning of this error?

That means that you don't have a separate boot partition. Instead the /boot is under /, the root partition. It also means that /boot is very far from the beginning of the disk.

Various systems may have problems when /boot is too high on a disk. Since your /boot is under /, it is on the end of the drive. Error simply warns you that /boot may be too high on a disk and that such position could cause problems.

In general, best way to do partitioning is to have a small boot partition at the beginning of the disk and mount it under /boot. This way the root partition may be anywhere.

The error is there because BIOSes have limits on position of boot partitions. There is a nice article here which explains several limitations which were common on BIOSes. Today, computers shouldn't have such problems, but it is always better to err on the safe side.

and what about size of the boot partion? – Milad Sobhkhiz Mar 29 '11 at 14:39
    
@Milad Sobhkhiz It's not going to be very easy. If you're having problems, then you'll need a boot partition at the beginning of the disk. Try to shrink your C partition form 97 GiB to for example 96 GiB and place the boot partition in the space you got after shrinking. Also note that boot partition should be a primary partition. – AndrejaKo Mar 29 '11 at 14:41
    
@Milad Sobhkhiz I think that 1 GiB should be enough for boot partition. – AndrejaKo Mar 29 '11 at 15:37
