I'm having an issue with my pc. I want to boot from USB flash drive. I enter BIOS and select the first boot device and select my USB flash drive. The changes do not reflect on the screen. If I just press F12 after post, and select my USB flash drive, it doesn't boot.
I disconnected two of three new HDD I've added to my array pool. I can now select and apply my boot order changes and boots properly. I have a total of 10 hdd (2tb each) but can only use 8 hdd to boot correctly. Is this a PSU issue? I'm currently running a 750w PC Power and Cooling PSU. No discrete gpu, only acting as a NAS.
I've tried clearing CMOS but no luck either. Should I start with replacing the PSU or mobo first?
