I have used our LiveUSBcreator for multiple installs but it always took care off everything for me.Including non PCLinuxOS ISOs ?
Well, no-just PCLinuxOS. I never realised that distros use different install methods.
Would other distros most likely fail using our LiveUSB creator, or is that just a precaution?
They will almost definitely fail ..... success would be accidental and unusual
LiveUSB Creator is designed for PCLOS ISOs and files only.
Okay, I have an 8 gig USB stick. Let's suppose I create 2 gig partitions and install PCLOS on one (using LiveUSB, or maybe even UNetbootin). If I install a different distro to each partition I assume I will need Grub to manage the boot process, correct? If so, any pointers on how to set up Grub to do that?
Select one of the installs to be the manager of the booting ..... lets say PCLOS.
You install the PCLOS Grub to the MBR, and the others to the boot sector of their respective partitions.
You can then edit the PCLOS menu.lst file to 'chainload' the other partitions.
That keeps things nice and clean.
Of course you can go one better ..... create a small FAT first partition with boot flag set. (a few MBs will do)
Into that install Grub.
Create a menu.lst file there with nothing but chainload commands for all the partitions.
Install that Grub to the MBR, and all the OS's grub installations to their partition boot sector.
Now you have your own grub on the first small partition, and can call any partition you wish.
Making changes to the OS on any partition does not change the Grub partition.
The only thing I would point out ...... not all utilities will allow you the freedom to select where to install grub, so be careful one of those does not try to take over.
