When you try to restart your PC, you get a blue screen error.Īnd on trying to configure boot options from BIOS options, you will only see SATA SSD and HDD. Thus, I would recommend reinstalling Windows with the other Windows drive disconnected.Īnother instance where this problem comes up is, while installing Windows on M.2 SSD, you physically removed all other storage devices from the motherboard (SATA SSD and SATA HDD). To continue with UEFI in booting and installation, check your boot options and disable secure boot, then look for UEFI settings and follow prompts.Īlso, if you reinstalled Windows, with Windows already installed on another connected drive, it may have reused the UEFI partition on that drive instead of writing it to your M.2. Either switch from UEFI to BIOS or get your installations for Windows for UEFI.
For instance, it’s probably because it’s in UEFI format. There are many reasons as to why this is the case.
