Hello!
I installed an Hyper-V 2012 core with two VM.
The hypervisor is on an 4TB raid and there are two other 1TB raid for backups, snapshots etc.
I saw, that the(4TB) drive was unexpected small (2TB) and via diskpart and a look into the BIOS settings i saw that everything was in legacy/BIOS mode.
I tried to Reinstall the Hyper-V in uefi and hoped that i only have to delete C:, but in the setup of the Hyper-V there where no disks shown, even in diskpart at the repair options.
Whats options do i have now? I need the full disk space, because one vm ist quite big.
Thank you in advance!
