Over the past few months I've learned enough to be dangerous with Ubuntu. My 2008/2009 MacBook Air hard drive crashed, I installed a new SSD, and begun setting up this machine to support my personal data & various development efforts + testing out different OS's.
I'm pretty sure I need to make changes and I'm researching + posting here to identify what they are. The image below shows the existing setup. Keys are, boot partition for chain loading / independant grub, potential for multiple OS's, personal files accessible by other OS's. When setting this up I did recieve some errors about GPT and the ubuntu partioning tool kept creating 1mb unallocated regions at beginning and end of drive.
- Change "bios_grub" partition to a primary ext4 and manually install grub2
- Move FAT as primary partiion behind bios_grub
- Swap after FAT (Signifying beginning of seconary logicals)
- /boot after swap, this ensures all logical partitions are in consecutive order (I thought I set it up like that but was tired when I started).
- Split up my / with a few partitions to support other Linux distros.
Summary of questions:
- Proposed changes make sense?
- Proposed changes made without formating disk / loosing data?
- How do I check if GPT is on the drive and should I be using that?
- Some handy terminal tools to trace booting and diagnose all may be helpful.
Image of existing Gparted below. Any help or direction is appreciated; I want to be sure before moving forward and possibly boching things up worse! At a first glance GParted / partitioning tools don't appear to be flexible enough to allow me to make the changes I need without creating a new table from scratch an deleting everything Thanks!
