This happens when you don't have a separate /boot partition. While it is allowed to have multiple /boot partitions, grub can only read from one by default, which in this case is your sabayon's /boot. Manually copy the other kernels and initrd to sabayon's /boot and then edit mnu.lst appropriately. Or look at device mapping in grub, where you don't have to do any manual copy. If you have multiple linux installations, its better to have a /boot partition and use it in all installs. Makes life easier. > > 2) What is the importance of a file system.

NTFS is a proprietary fs from Microsoft. ext[2,3,4]/ jfs /xfs et al are nix/bsd filesystems that have their own usage criteria. Dig deeper here: http://www.sabi.co.uk/Notes/linuxFS.html & here: http://www.debian-administration.org/articles/388 > 3) What should be the file system and mount point of a partition for > data storage. > Mount point can be anything, it's up to you to define. Filesystem depends upon what you're storing in there. IMHO, ext3 or xfs are pretty stable and been use in a long time. If you want windows to be able to read that partition your options are limited to fat32 or ntfs. > 4) If i delete all partitions , can the data which was in a > partition, be restored .??? > No. If it's a journalled filesystem then no in most cases. There are tools which allow file/folder recovery but I haven't seen any which can recreate full partitions. > 5) What is the best way of doing partitions ????? > Just remember to have a /boot as a primary boot partiton for all linux installations ~ 500MB. Rest is all up to you. I keep a separate /home partition (~60G) which I use as home on all linux installations. Rest all goes to distro root partition. EG: <boot-500M><root1-10G><root2-10G><root3-10G><home-60G> Now root1,2,3 can have any linux installation and all my settings in /home will work fine regardless of which distro i'm on. As a general tip, try going through Linux From Scratch or Gentoo Handbook to get familiar with Linux userspace. > > Kindly help. > _______________________________________________ > Ilugd mailing list > Ilugd@lists.linux-delhi.org > http://frodo.hserus.net/mailman/listinfo/ilugd > -- -- Ankit Chaturvedi GPG: 05DE FDC5 468B 7D9F 9F45 72F1 F7B9 9E16 ECA2 CC23 <http://www.google.com/profiles/ankit.chaturvedi> _______________________________________________ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd
