Monday I purchased the Intel 750 (400gb) nvme ssd for my GB z170x gaming 7 mb.
I did a clean install of W8.1pro with an Rufus uefi usb stick and initially every went okay, until I switched off my pc.
After a cold boot I get a msg. Reboot and select a proper Boot device.
Checked all settings in the bios, and Windows bootmanager is listed as the First boot option.
storage boot option and other pci device Rom have been set at UEFI.
Have already installed a different Bios but still the problem.
So a reset goes perfectly but a cold but gives the problem.
Any tips before I return this 750 to the shop?
Intel Toolbox and latest Nvme drivers installed.
Tks.
