I've recently built a new PC (upgrading from GTX550...), but it won't boot from my Windows 10 USB in UEFI, resulting in not being able to install Windows.
- Will boot straight to UEFI/BIOS
- Will boot from USB if set to Legacy boot mode Hardware list:
EVGA Z170 Classified K (BIOS v1.04)
G.SKILL Tridentz 3200 16GB (8GBx2)
EVGA GTX1080 FTW Hybrid
Samsung 960 evo m.2 (500GB)
Samsung 850 evo sata(1TB)
Corsair H100i v2
EVGA SuperNova 850 G3 Attempts of solving the issue:
Here are some actions i tried before posting:
- Disable USB Legacy mode
- Set USB Key to top of boot priority list
- Disable CSM
- Tried both in AHCI / RAID SATA
- Disconnect all SATA drives
- Installed Windows in Legacy boot (results in MBR partition) to install Z170 drivers and NVMe driver, then try to boot in UEFI from USB, to no avail.
- Windows 10 USB is purchased from Microsoft, it is in FAT32 format. I assume they were made with clean installations in mind.
Is there something I'm missing? or am I taking the wrong steps into install Windows in a NVMe SSD?
This is my first time dealing with UEFI, so please forgive me if there's some sort of stupid mistake I'm making.
Any help is appreciated. Thank you in advance.Solution:
(or more like how I solved the problem)
- Boot with Legacy, and install Windows 10 (MBR Partition) to a spare SATA Drive
- Create Windows10 Install Media with Microsoft's Media Creation Tool
- Turn off machine, then disconnect all SATA drives from MB
- Turn on machine and boot to UEFI/BIOS, then restore to default settings
- Turn off Fast Boot, and disable CSM
- Make sure Boot is set to UEFI, and list USB Key as top priority
- Save and Reset
After that, it boots to the USB Media I just created with the Media Creation Tool.
