SER5 MAX will not boot from scratch Win11p install

dmk888

I cleaned the NVMe partition table on first boot, downloaded a nice fresh Win11p media creation-made install USB, and installed to the NVMe without incident. The drive shows in the BIOS, but not as a “Windows Boot Manager” option like the other half dozen SER5s I’ve got. There is no CSM option in the BIOS and I’ve tried just about everything to no avail. I’ve even imaged a working NVMe onto another drive and it gets further but will not boot either. Please help.

Hello there,

Could you please send us a picture of SN code(two lines) at the bottom of machine ?

You can try to clear CMOS : Please turn off the PC , unplug the power supply and HDMI cable , and press the CMOS pinhole ( the CMOS pinhole is in the audio port) for about 10 seconds. Ten minutes later, plug the power supply and HDMI cable, turn on the PC again.
Please wait about one or two minute, if you can go to the system.
Please repeatedly press delete key as soon as your restart the PC, go to BIOS. Go to Boot option, enable fast boot, press F4 to save.
Here is the tutorial ：https://mega.nz/file/XypwTISY#DVT0BsjOgiPkZ-drQaj88JH9Z7f7qpKGP2E3nMHW8ms

Have a nice day~

I continue to struggle with this PC.

I can’t get more than 50pct through an install of ANYTHING from Windows to Linux before it just shuts itself down.

Hello there,

After analyzing your issue, we do not consider the SSD itself as the root cause for the failures, and here is our breakdown plus recommended actions:

Issue Analysis
In your first phase of setup: The NVMe drive could be detected in BIOS, Windows installed successfully, and disk imaging finished partially.

These facts prove the SSD’s basic read/write hardware function works normally. The missing Windows Boot Manager entry in BIOS is mainly caused by UEFI firmware compatibility on this specific unit, rather than SSD hardware damage.

The random full-system shutdown halfway through OS installation (applies to Windows, Linux and all other systems) is a classic sign of abnormal power supply, thermal throttling or motherboard NVMe slot power delivery faults on the mini PC.

Sudden power-offs during installation only damaged the SSD partition table secondarily, instead of being triggered by a faulty SSD.

Suggested Verification Steps
Cross-test the SSD: Install this NVMe drive into another working SER5 unit from your fleet.

If the drive can complete OS installation and boot properly there, the SSD is confirmed healthy, and the defect lies with the original machine’s motherboard/power module.

Test a known-good NVMe SSD on the problematic unit: If the new drive also suffers random shutdowns during OS setup, the root cause is definitely the host device rather than your original SSD.

After cross-verification, we can arrange targeted after-sales support for the faulty hardware accordingly.

Please let us know your cross-test results whenever you are available, we will follow up promptly!

Have a nice day~
