I'm exploring CachyOS and have the ISO file ready, but I don't have a USB drive on hand. I was thinking about using a small partition from my external SSD instead. However, every flashing software I tried, like Balena, Rufus, and Ventoy, attempts to flash the entire SSD instead of just the specific partition I want to use. Is there a workaround to create a bootable partition on my SSD, or do I need to find a USB drive?

I saw USB sticks for just $5 at a drug store the other day. Definitely worth considering if you need something quickly.
Honestly, getting a USB stick would be the easiest solution since they're pretty cheap and can save you a lot of hassle. But if you really want to go the partition route, you can flash the ISO directly to a partition using a method like direct write in Linux. Just keep in mind that it's a bit more complex than the usual software options.
If you decide to stick with your external SSD, Ventoy might help you out. However, it usually requires wiping the SSD first, creating two partitions—a small bootable one for Ventoy, and a larger one for storing any ISOs you want. I found it helpful for having multiple OSes and tools on one drive, but just make sure you back up any important data first!
Wait, did you mean you installed the ISO onto your system? You typically don’t install an ISO like that; usually, you’d boot from it using something like a USB drive. Just checking because the process can be a bit confusing!
