Hello everyone! I don't know if I'm posting this in the right place, but I'm giving it a shot and hope that I can get some good help. I've just built a new computer here and I have a Samsung 980 Pro M.2 NVMe boot drive, and installed 3x WD Red drives for storage. I have now tried installing Windows 10 21H2 and I am selecting the NVMe drive to install when asked where I want to install the operating system and it runs through the installation just fine, everything works etc etc. But then when I go look in the disk manager I can see that it has partitioned the NVMe drive (Drive 3) such that it has the system installation on it (and a smaller OEM partition whatever that is). Then it has partitioned one of the WD Red drives (Drive 0) to contain the System Reserved Partition(!?!) and also it looks like another unused partition??? I thought it was supposed to put ALL the special partitions needed to boot the computer on the boot drive? Is this a bug in the installer or what is going on? Any help or insight into why this is happening would be very helpful, as well as some guidance on how to avoid this happening.... Kindest regards.
The Setup program might have preferred the WD drive for booting over the NVME one. This can sometimes be troublesome if a system prioritizes e. g. SATA drives over M2 ones. Best practice: Connect all WD drives only AFTER Setup is complete. That way, Setup has no choice but to use the NVME drive.
Thank you for the suggestion! I could disable the SATA drives in BIOS for the installation. Will try this tomorrow. Kindest regards.
not disconnect ! or disable sata in bios use this methode disconnect any mechanical drive ! more safe !
If what you are saying is I should not be disabling the mechanical drives in BIOS, but actually physically UNPLUG them either on the drive side or the motherboard side, then this would be very hard for me to accomplish due to the clean cable management in the new computer build as well as the graphics card actually blocking access to the SATA ports on the motherboard making it necessary to completely remove these if I were to be able to do that. I tried simply disabling the 3x mechanical drives in the BIOS and that has made it so that the Windows Setup can only see the NVMe drive, which should make it possible for me to install now without having that stupid issue of the System Reserved partition ending up on Drive 0 (First mechanical drive) instead of Drive 3 (NVMe).
