Short version:
I need to edit the partition number of the boot manager as it seems to point to a non existent hard drive.
In old MBR speak, I want to set the right drive active and edit the boot.ini to match. But under uefi bcd.
Long version:
Frequent crashing lead to to try and reset my win 10 install on the weekend. After multiple attempts that went nowhere, I created a USB boot stick with the win 10 media tool and set about the install.
Which also had issues because of partition ordering problems.
I ended up deleting the boot/system partitions on the m2 drive figuring windows would figure it out...
But each time it boots it seems to want to go to a partition 3 and fails. The only way I can boot is to boot off the USB, and go to repair. Then the boot menu has "exit and boot win 10 on partition 4" which is successful.
I've poked around with easybcd and visual bad and it looks like the successful boot is reading the bcd from a hard-drive 10. But that doesn't exit when I look under the driveletters tool. There's a 9 and there's a 12 (and others) but no 10 (nor 11).
I also see many windows boot managers when I hit the uefi boot menu on start up.
If this was mbr, I could just edit the boot.ini on each partition and add multiple options to try different drives and partitions. And then once I work out which one is correct, delete the other entries.
But easybcd etc only seem to let me pick "drive letter c" and so on. Which doesn't work because it seems to be saving to an invalid store (accessible when booting to repair via USB rather than booting from one of the drives). Grr.
Push comes to shove I'll create another partition on the drive, disconnect the data drives and try another install on the weekend. But if anyone can help me get into the guts of the bcd and clean it right up, appreciated.
