need help on /boot partition!
hi all
i want to install opensuse and fedora 9 in my PC. i have a win xp pro too. I've not any problem with dual boot (Linux and windows). i want to know: is it a good idea to create a boot partition for my Linux installation? and if it' good, should i create one boot partition for each Linux? one for fedora and one for opensuse. for example i have a 2gb swap partition and I'm using it for both Linuxes! what size of boot partition is enough for me? thanks all |
Assuming your boot loader is similar to the GRUB, you would probably be happier with a single boot directory shared by all your distributions. The main advantage of that arrangement is that you only have one boot configuration file that will need to be modified when any of the distributions change.
On the other hand, if you use your BIOS to select a boot location when you boot, then all distribution can be on different drives, with their own boot loader on that drive. The advantage of that arrangement is that each distribution is completely isolated from any other distribution. Thus each distribution can manage it's own loader without any possibility of changes in that distribution impinging on the loading of other distributions. Note, however, that this method does require that each distribution be on a different physical drive unless your BIOS can activate a specific partition as a "boot" partition "on the fly." That's because each distribution in this method is using a different boot loader. |
really what is /boot partition? why we use it?

You don't need /boot partition and I wouldn't recommend that you create one.Install Fedora's or Suse's boot loader on the MBR and the other one on the root partition.Since you are having Window$ put Linux distros on the logical partitions and Window$ on the primary,otherwise you may run into the problems while trying to boot into the Window$.

Here's a link that describes what a boot partition is and reasons for using it. It is written specifically with Ubuntu in mind but the basic theory is the same for any distribution:
http://users.bigpond.net.au/hermanzo...boot_partition If you have multiple distributions, you will need to edit the menu.lst file and place entries there so you can see them on boot. This file is in the /boot/grub directory. In Fedora, it is named grub.conf rather than menu.lst. |
If you use Fedora, you had better install a boot partition. Fedora's default installation will give you a virtual drive, and you can't boot from that. Once you set up one boot partition you can boot as many distros from it as you choose, if you use grub and proper configuration.

Use /boot directory but not a separate boot partition

What I try to do when I perform an installation is that I attempt to create a GRUB menu configuration for each system, but instead of installing it to the MBR, the Master Boot Record, instead I install it to the /boot/grub directory of each system I install. Then, once everything is installed, I go back to the system from which I want to manage GRUB, mount the file system of the system I recently installed, and copy the GRUB menu entry from that system to the one I am using to manage the MBR instance of GRUB. That works with one exception - if the GRUB entry has a SCSI disk ID for the location, it may have to be replaced by the device name or, if you can find it, the UUID. Then the scheme works properly. This may all be confusing, though, so if there is anything that you do not understand, please ask. Hope this helps and is not too confusing. |
The comments and references above should make it clear to you. Be sure that you understand the difference between a partition and a directory, and the difference between the directory organization on a Linux system and a Windows system. (Basically, that Linux uses a single file system, and Windows uses a separate file system for each partition.)
This may help you follow the advice offered by masinick: Quote:

If you want to use an encrypted root file system (probably a good idea for a laptop at least), a separate /boot partition will be necessary.

True, though some consider whole partition encryption more secure than directory encryption. If you put /home on its own partition,then you might as well have done /boot. The point is, for partition level encryption, you need at least 2 partitions...but we're probably getting off the OP's topic.
