I have mechanical HDD with windows 10 pro -it is labled disk0. I bought a new NVME2 and installed win 10 pro it is labeled disk1. I did not disconnect disk0 when I installed disk1. when I boot up I get a screen which asks me to select disk 0 or disk 1, and can get into either one no problem.
I decided I didn't need disk0 anymore and wanted to get rid of all partitions on it so went into cmd>diskpart>select disk 0>clean. this deleted everything in disk 0.
now disk1 doesn't look like it has any of that reserved windows partition, boot\file page\etc. so when I restarted my computer, it keeps asking for boot file. I guess it relied on disk 0 to boot. is there any way to make disk1 bootable? or do I need a fresh reinstall of windows on disk1 (and make sure I don't connect disk0)?
I tried reinstalling windows on disk 0, but I don't get that dual boot screen selection option anymore. it just boots straight to disk 0.
