I have 6 partitions with grub from an existing Linux OS on /dev/sda8. I want to install 12.04 on /dev/sda1 but since this partition has 31G allocated i want to resize it to 10G and create 2 more partitions from the remaining space. I want to know if by doing this will all my existing partitions get shifted and thereby i might have to reinstall them again or is it just a matter of reinstalling the grub on one of them (say Ubuntu) and add the remaining ones?
I've sda1, sda5, sda6, sda7(swap), sda8, sda9, sda10, i plan to delete sda1 and recreate 3 partitions and have 12.04 installed in one of them, the existing ones might also get shifted, as a result grub on sda8 might not work so my machine would be completely unusable until grub is fixed.
Will a resulting not optimal partition order cause any of the existing Linux OS's to not boot or is it just a bad partition table arrangement which won't really affect any OS in the disk?
I had a bad experience last time around when disk numberings got rearranged and i had a tough time recovering everything. Don't remember what happened, so wanted to avoid any such issue this time.
Edit: @Elijah/@Takkat - This is my first time using this website so didn't know i had to edit my original questions for additional information. I'll do that going forward. However i didn't find any delete option for two of my answers to remove them. Can you please remove those two answers? Thanks in advance.
