Alright so first things first I’m a newbie to PC building and wanted to do it for so long- yay for adult money!

Here are my parts to begin with (US based)
Corsair 3500X RS
Corsair iCUE Link Titan 360 RX
Gigabyte Radeon RX 9060 XT 16gb
ASUS ROG Strix B550-F
Corsair RM750e
AMD Ryzen 5
T-force delta RGB DDR4 16gb

Now, I got it installed 2 separate times. After the first time, I unplugged the USB I booted it with and it crashed back to bios and I was able to reinstall with the same USB and it went back like nothing happened. I played on it for weeks no issues. NOW I tried to remove the USB again, and it ran fine, saw there was a software update and restarted and bam back to BIOs. Now it will not load anything. I have a Mac mini as my other computer so I’ve used Balenaetcher to flash the iso file onto the drive and then also worked in terminal via Claude instructions… and I’m so stuck. Any advice????
