If you want to run os from USB then why don't u try hive os? If it's only for mining I think hive os is better for the driver configuration. If you insist on using windows then 120 gb ssd is quite cheap right now.
May be the OP can't configure the miner themselves? No matter what some people will never be friendly with Linux based OS, they are better off with windows OS for Mining, I could remember the first time I tried Linux out, it's was hell 🤣🤣🤣
You have obviosously never used a modern linux based mining OS. There is very little linux involved with the user. mmpOS / HiveOS / RavenOS / Smos...are all simple and easy linux OSes. In fact they are much easier than working in windows ..no drivers...no swap files...no virtual memory issues or mysterious system updates that break everything.
When we recommend switching to linux mining os..we are not talking about you just downloading and using the genersl linux os. That does require a bit more knowledge and work. We are talking about an OS that fits on a thumb drive and has a gui inteface for everything you need to do. Most linux mining oses run from a web panel. You are saying you can handle a web interface with sliders and check boxes for settings. No linux knowledge required. Best of all people can try them for free and without even removing or replacing thier windows OS.
Its your fear of the cli that holds you back...and funny part is you dont have to ever work from a flashing cursor if it bothers you so much. The tools are superb. In fact memory tweaks are easy these days. Even flashing bios is easy on these oses.
I would not recommend windows off usb thumbdrive. Linux mining os sure.
Have had to replace more risers than thumbdrives in last 5 + yrs of mining.
