I have a 1GB USB stick which is too small to fit any useful data but manages to run a custom Arch-iso. So I thought it would be a good idea to create a live stick for emergencies with tools I might be needing.
The problem is I don't know (yet) which tools might be useful until I really need them. Right now it fits intel graphics driver, LXDE, Chromium and ZFS tools. A partitioning tool would probably be handy.
If you're trying to save space, Arch should already have fdisk and possibly gdisk installed. They're CLI programs though, so if you'd rather use a GUI, go for gparted, as @Th3Z0ne said.
It doesn't really matter whether you go for the normal or the portable version. The portable version just means that Rufus will run from a single exe file, rather than going through the process of being installed on your PC.
rufus is 100% the way to go on windows win32 disk imager is also a option but i have had it destroy a drive when windows just randomly ejected it
dd on linux is amazing too unetbootin is kinda meh but is a option if dd fails
as for the OP question. Here is a good list of what you need
gparted | good partitioning tool ddrescue | always a good thing to have filesystem drivers | might need to mount ntfs, hfs+, etc linux-headers | might need to make a kernel driver all of the grub tools | incase grub poops out on you networking drivers | might not have what you need already installed adb | a good thing to have since it is small and you never know when you will need it
This installation will be on new build booting for the very first time, so do you still think I should use Rufus? I'm still having an issue where the drives are not found, and this after a new download.
Unless you are not using an ISO file from the usual sources I can't imagine anything to go wrong.
If you say 'new build' I guess you are having a recent motherboard, right? Your bootable stick should show up after plugging it in and rebooting into BIOS/UEFI. Rufus allows you set up your stick for both variations, for a modern build however I recommend the option "GPT partition scheme for UEFI".
Me as well. I'm willing to bet it has a variant of every tool posted above (haven't read them), and has had every tool I've ever needed on it, at least to some extent.
