Greetings,
New here, and struggling to boot StartOS (nonfree.iso) on my desktop for a Bitcoin node setup due to a “Reboot and select proper boot device” error or BIOS loop. Below are my hardware specs and a summary of steps taken.
Hardware Specs
- Motherboard: MSI MAG Z390 Tomahawk (MS-7B18)
- CPU: Intel Core i5-9600K @ 3.70GHz
- RAM: 16GB
- Storage: Samsung SSD 970 EVO Plus 500GB (NVMe M.2)
- Additional Storage: 1TB Drive
- Notes: 2018-era board, integrated graphics, Ethernet for BTC node.
Installation and Troubleshooting Steps
- Install:
- Flashed nonfree.iso to USB, booted, and installed on Samsung SSD (erase confirmed).
- Install succeeded, removed USB, and rebooted.
- Result: “Reboot and select proper boot device or insert boot media in selected boot device and press a key” error.
- BIOS Adjustments (Round 1):
- Set Boot Mode Select to LEGACY+UEFI, Boot Option #1 to “Hard Disk: Samsung SSD.”
- Saved/exited.
- Result: Same boot error.
- BIOS Adjustments (Round 2):
- Set Boot Mode Select to UEFI, Boot Option #1 to “UEFI Hard Disk.”
- Confirmed Secure Boot and Fast Boot Disabled.
- SATA Configuration: AHCI mode, M.2/Optane Genie Disabled.
- Saved/exited.
- Result: Boots to BIOS menu (loop).
- Other Checks:
- No standalone CSM option (part of LEGACY+UEFI).
- Tried reinstalling in both UEFI and LEGACY+UEFI modes, same issues.
My search results have not yielded anything so far.
Tried to be as complete as possible to give an idea of what I’ve tried so far.
Any advice is appreciated!
